OverviewThe development of UMTS has increased the need for dynamic networks that can be configured by remote real-time access. Remote-controlled electrical downtilt (RET) has become one of the most important features of such networks, providing several benefits including:

❑ easy configuration/tuning of new equipment.

❑ power control and cell breathing through variation of antenna coverage footprints.

❑ fine tuning of soft handover situations during running operation.

❑ real-time adaptation to changes in capacity need, for example during rush hours.

❑ remote re-configuration when changing network plans or expanding existing networks.

The Powerwave RET System is designed to meet the high requirements for reliability, flexibility and efficiency needed for remote control of mast-mounted telecommunication equipment. The system consists of a Master Control Unit (MCU), and one or more Antenna Line Devices (ALDs).

MCUThe Master Control Unit (MCU) controls the Antenna Line Devices (ALDs) and supplies DC power to them on a common bus. ALDs are connected to the MCU either by using the existing RF feeders in your system, or by using a separate cable.

Powerwave offers a complete range of MCUs, RET units, TMAs, and supplementary equipment, all parts of which are compatible with the requirements of the AISG specification.

The MCU monitors system status, and receives commands and configuration instructions from a Network Operations Center (NOC). You can access an MCU through a site LAN by using a web browser, through an SNMP agent by using the Powerwave NetWay Manager (NWM), through a standard Telnet client, or by using a text terminal. The MCU acts as the primary station, controlling data signalling as well as ongoing activities. The ALDs act as secondary stations reporting data and carrying out instructions received from the MCU.

A standard MCU is illustrated in Figure 1-2. Operations such as electrical tilting of antennas and setting of TMA gain can be performed from a remote NOC using a web or an SNMP interface. Local management of the MCU at the base station is also possible by connecting a computer directly to the local ethernet port on the MCU. The MCU has three AISG-compatible ALD ports and is available in +24 VDC, -48 VDC or 115/230 VAC versions. .

Figure 1-2 Standard MCU

On a Layer One Conversion (LOC) MCU, the multi-pole AISG connectors are replaced with SMA female to deliver DC power and AISG signalling. The RF ports make it possible to use Current Injectors (CINs) instead of Current Injector and Layer One Converters (CILOCs) at the Base Transceiver Station (BTS) end in RF feeder configurations. The CINs must be able to transfer signals at the AISG sub-carrier frequency 2.176 MHz

RET UnitsA RET unit consists of one, two, or three stepping motors that can be connected to the positioning racks used for adjusting the electrical down tilt of MET antennas. When it receives a command from the MCU, a stepping motor moves the positioning rack up or down to achieve the desired antenna tilt angle.

There are two types of RET units, one with a small housing and one with a large housing. RET units in small housings are mainly used for single-band antennas with a single RET positioning rack. RET units in large housings are used for dual-band and triple-band antennas with one, two or three RET positioning racks. The small and large RET modules are illustrated in Figure 1-3.

RET units can be mounted on an antenna that is already mounted in place on site. They can also be delivered mounted on a Powerwave antenna. The connection to the MCU is made using the AISG compliant connector. An additional connector is available for daisy-chaining of several RET units or connecting to other types of ALDs.

i-RET UnitsThe i-RET units are integrated in the Powerwave 8000 series antennas. They perform the same actions as a standard RET. Each i-RET unit controls one band on an antenna so, for example, dual band antennas will contain two i-RET units as shown in Figure 1-4.

Figure 1-4 Dual Band Antenna with Two i-RET Units

i-RET Antennas also contain an Absolute Position Sensor, which is a passive unit that tracks the tilt position of the antenna. If an i-RET is removed from its antenna, the antenna is held into position. When a new i-RET is installed (or the existing i-RET is replaced), it notes the position on the sensor and sets itself appropriately.

TMAsPowerwave provides AISG-compatible TMAs with built-in CILOC functionality that can be used in RF feeder configurations. Both variable and fixed gain TMAs are available for GSM and UMTS networks. DC supply and AISG signals to TMAs and other ALDs are transferred via the RF feeder. Monitoring of TMA alarms and configuration of RF gain can be performed for both branches. A TMA is shown in Figure 1-5.

CILOCsThe CILOCs use an ordinary RF feeder cable to transfer DC power and AISG signalling to ALDs, such as RETs.

Figure 1-6 CILOC

ICILOCsThe intelligent CILOC (ICILOC) is used for RET unit installation on sites that have non-AISG TMAs so that current level alarms can be monitored. The ICILOC provides the DC supply and an evaluation of DC current alarms for the TMA that is installed between the ICILOC and the antenna, as well as an additional TMA connected to the ICILOC DC voltage supply connector. Active voltage regulation is implemented within the ICILOC to provide DC transfer at the specified voltage level from the BTS port to the TMA DC ports.

The ICILOC provides a signaling link to the BTS following AISG standards. It converts and transfers the signalling from the RET port to the BTS, and adds signalling from the TMA DC alarm evaluations.

CINsIf you use a LOC MCU you can use CINs instead of CILOCs at the BTS end for injecting DC and AISG signals to the ALDs in the RF feeder. CINs for indoor and outdoor use are available for different RF frequencies and have a built-in lightning protection circuit. Note that CINs used together with the LOC MCU must be able to transfer signals at the AISG sub-carrier frequency 2.176 MHz.

Lightning ProtectionThe lightning protection unit protects the ALD ports on the MCU from damage due to lightning strikes in the mast and cables.

Figure 1-8 Lightning protection

Software and Data StorageThe software for the RET System includes functions for control of hardware functionality, system performance, MCU and ALD alarms, and system communication. Software modules are stored in the MCU, RET unit, ICILOC, and TMA; and are executed by CPUs in these units. New software can be downloaded remotely for all units.

The Powerwave RET system uses AISG standards, and has a Management Information Base (MIB) that lists all of the configuration parameters for each device in an RET system. Depending on the parameter, it may be stored in the individual device, or in the MCU. For example, while the MCU only saves information needed to identify connected ALDs, each ALD stores all of its configuration data locally. Production data for each device (MCU and ALD) is stored locally in the permanent memory in each unit.

System ManagementThe RET System can be managed locally or remotely. Local management is performed using a PC connected to the Local Ethernet port on the MCU. Remote supervision, control and maintenance from a NOC can be performed via NWM, or by an internet browser connected through a site LAN. All system software can be updated from any management terminal, both locally and remotely.

The management system is based on open standards. Each MCU includes a web server, an SNMP agent,and a Command Line Interface (CLI). This makes it possible to manage the RET System using a web

NOTE CILOCs or CINs in your system will protect the RF BTS port from lightning. Powerwave recommends that a Lightning protector is included in your configuration, however, to ensure protection of your complete system.

Chapter 2Controls, Indicators, and Connections

IntroductionThis chapter contains descriptions of the controls, indicators and connections of the RET System.

MCU / LOC MCUThe MCU and LOC MCU, illustrated in Figures 2-1 and 2-2, each have three ALD signalling ports. The standard MCU has three AISG-compatible ALD ports while the LOC MCU has three SMA RF ports. Each port is capable of supporting 12 devices. DC power provided to each ALD is +24 V. In addition to the ALD ports, the MCU has the following ports for system management:

❑ 2 Ethernet ports: one Local Ethernet 10/100 BaseT port for connection to a computer, and one 10 BaseT port for connection to a site LAN.

❑ 1 RS-232 DTE port for serial communication (for factory use only).

❑ 8 alarm sensing ports (IN ports) for surveillance of external functions/equipment.

❑ 2 control ports (OUT ports) for control of external functions/equipment via single pole, double throw (SPDT) relays. Each relay can switch one common line between two contacts – one that is normally closed (NC) and one that is normally open (NO).

MCU Reset SwitchThe MCU has a hard reset switch located next to the Power LED on the front panel. Use a pin or paperclip to press this switch and reset all values in the MCU back to factory defaults. Only use this switch as a final option in the event the MCU locks-up.

LOC MCU CablesThe LOC MCU cables are RF cables for connecting the ALD ports on a LOC MCU to CINs with SMA or SMB connectors.

DC Power Supply CableThe DC power supply cable for the 24 V MCU and the -48 V MCU is equipped with a MATE-N-LOK connector at the MCU end. You must mount a connector that fits your DC power source at the other end of the power cable.

RET ModulesEach RET module has two connectors; an input connector for communication to the MCU and an output connector for daisy-chain configurations.

TMAsAISG TMAs have input and output RF connectors and the DC supply and AISG signalling is transferred via the RF feeder connected to the BTS 0 port.

With combinations of the ICILOC and standard TMAs, the DC only is sent to the BTS port.

Chapter 3Installation

IntroductionThis chapter contains unpacking, inspection and installation instructions for the RET System.

Site SurveyPowerwave recommends that a site survey be performed prior to equipment ordering or installation. Performing a detailed site survey reduces or eliminates installation and turn-up delays. Pay particular attention to power cabling and breaker requirements, as well as RF cabling requirements. Specifications are listed in Chapter 5.

Unpacking and InspectionThis equipment has been operated, tested, and calibrated at the factory. Carefully open containers to remove equipment. Retain all packing material that can be reassembled in the event unit must be returned to the factory. Perform the following steps:

1. Visually inspect equipment for damage that may have occurred during shipment. If possible, in the presence of the delivery person.

2. Check for evidence of water damage, bent or warped chassis, loose screws or nuts, or extraneous packing material in connectors.

If equipment is damaged, file a claim with the carrier once the extent of any damage is assessed. If equipment must be returned to factory, please contact Powerwave for a Return Material Authorization (RMA). See Chapter 4.

Required ToolsThe following tools are required for RET System installation:

Installation Options Remote Electrical Tilt (RET)

3-2 044-05288 Rev C

Installation OptionsThere are two ways to connect the MCU to the ALDs:

1. Use a separate cable.2. Use the existing RF feeder cable.

Separate Cable ConfigurationThe example illustrated in Figure 3-2 shows three daisy-chained RET units mounted on Powerwave MET antennas. DC supply and data signalling is distributed to the RET units via a separate cable connected to the MCU.

Figure 3-2 Separate RET System Cable Configuration

RF Feeder ConfigurationRF feeders connect the MCU to the ALDs in several different ways depending on your overall system design. Figure 3-3 illustrates two common ways of implementing an RF feeder configuration:

❑ Using CILOCs at both base station and antenna end.

❑ Using CILOCs at the base station end and AISG-compatible TMAs with built-in CILOC functionality at the antenna end. Remote configuration of TMA gain and supervision of TMA alarms for both branches is in this case possible via the MCU.

044-05288 Rev C 3-3

It is also possible to use a LOC MCU with built-in layer one conversion and RF outputs (SMA connectors) for DC supply and AISG signalling with either option. The CILOCs at the BTS end can then be replaced by CINs with capability of transferring signals at the AISG sub-carrier frequency (2.176 MHz).

Figure 3-3 RF Feeder Configurations Installation Options

I-CILOC ConfigurationThe I-CILOC configuration, illustrated in Figure 3-4, uses standard TMAs & CINs, along with a LOC MCU. At the BTS, the RF sub-carrier and DC power is output onto the feeder cable through a a standard CIN. To do so, the CIN must pass the AISG sub-carrier frequency. At the other end, the feeder cable connects to the I-CILOC on the tower.

The I-CILOC has four ports: a DIN connector port for the connection to the BTS, a DIN connector port for the connection to the Antenna (ANT), an SMA connector port for DC power, and an AISG port to connect to a RET. The I-CILOC receives the RF sub-carrier and DC power from the feeder line and distributes the DC power to the primary TMA through the port labeled ANT, and to the diversity dualband TMA CIN through the

DC port. The I-CILOC converts the RF sub-carrier into RS-485 data distributes the data and DC power to the AISG RET port.

Figure 3-4 I-CILOC Installation

Cable InstallationDimensioning RET System CablesThe voltage drop across the system cables, connectors and equipment can limit the maximum cable length in the system and the maximum number of ALDs that can be connected. However, in practice, the maximum cable length in the RET System is normally not a limiting factor when designing Node B/BTS sites.

Cable ReliefsWhen you connect the RET System cables to the ALDs it is very important that you add cable reliefs at each connection point. This allows the cable to stretch and shrink due to variations in temperature without causing stress on the connectors. Always add cable reliefs as illustrated in Figure 3-5.

Connector VulcanizationDo not vulcanize AISG connectors on Powerwave products (including RET units, TMAs, and CILOCS) whether or not the connectors are attached. The connectors themselves have an IP67 ingress protection rating, which means they are dust proof and protected from temporary immersion in 1 meter deep water for 30 minutes.

Antenna InstallationFor instructions on how to mount the MET antenna, refer to the appropriate antenna mounting instructions.

RET Unit InstallationThe following sections describe the steps for installing the RET unit.

Small HousingFollow the steps listed below to install a RET contained in a small housing (single band).

1. Use a pozidrive screwdriver to loosen the locking screw of the locking device.2. Pull the tab of the locking device to release the positioning rod.3. Unscrew the two torx screws that hold the locking device in place.4. Slide the locking device off the positioning rod.

CAUTION: Vulcanization can weaken the protection and make the connectors more sensitive to dust and water.

WARNING: RF radiation can cause serious harm. If you mount the RET unit on an antenna that is already in place, make sure that all RF signals to the antenna are turned off.

Remote Electrical Tilt (RET) Preparing the Power Cable

044-05288 Rev C 3-25

Preparing the Power CableDepending on the product version, the MCU will either be designed for AC or DC power. MCUs that require a DC power supply are equipped with a MATE-N-LOK connector (male) on the front panel (1).

You must mount a connector that fits your DC power source at the other end of the power cable, by connecting the black lead to the positive terminal on your power source. The required voltage level, +24 V or -48 V is indicated on the front panel of the unit.

Pin 1 (to the left on the MCU when seen from the front) is connected to positive voltage, and pin 2 (to the right) is connected to negative voltage. The MCU is equipped with a protection circuit that prevents it from starting if the polarity of the power supply voltage is reversed. MCUs requiring an AC power supply have a power inlet (male) at the back (2).

Figure 3-11 MCU Alternative Power Inputs

Initial Start-up Procedure.Follow the steps below to start the MCU and connected ALDs.

1. Power-up the MCU by connecting the power cable. 2. Verify Power and ALD Port LED indications.3. Wait until the MCU has finished booting and the Power LED has stopped flashing before

establishing a local management connection.

Establishing a Local Management ConnectionThe MCU can be managed both locally and remotely, but when accessing the MCU for the first time you must connect locally. A web browser, an SNMP manager, a Telnet client or a text terminal may be used to configure the system.

Verify that your PC is using dynamic IP addressing. This is the default case for most computers, but if you are unsure you can configure your PC by following the steps listed below.

NOTE Do not connect the power cable until you are ready to start up the system.

NOTE The first time you switch on the MCU it may take several minutes for the MCU to scan the AISG bus for connected devices and retrieve device information.

Configuring and Calibrating the System Remote Electrical Tilt (RET)

3-34 044-05288 Rev C

Configuring and Calibrating the SystemBefore you can configure your system:

❑ Verify that you have notes from the mechanical installation of the ALDs at hand. The notes should contain the information needed to identify different ALDs in the system, as well as information about the antenna the ALDs are connected to. If you are unsure of what information you need, it is recommended that you read the instructions in this chapter and acquire the necessary information before attempting to configure the system.

❑ Verify that you have files containing correct antenna configuration data for your RET units. Antenna configuration files for different Powerwave antennas are available from Technical Support at Powerwave, or at http://www.powerwave.com/retconfigfiles.asp.

WorkflowWhen you have installed new units, you must perform the relevant actions listed below. Depending on which type of units you have installed, some actions may not be applicable.

1. Establish a local or remote management connection.

2. Start your web browser and log on to the MCU.

3. Enter information about a new MCU.

4. Configure the device scan procedure for a new MCU.

5. Upload antenna configuration data to new RET units.

6. Enter information about new ALDs to make it possible to distinguish them from each other.

7. Calibrate new RET units.

NOTE You must always recalibrate the RET unit after mounting a RET unit back on an antenna and/or if you upload a configuration file.

Configuring Device ScanIf the device scan process is too slow due to many non-responsive ALDs in your system, you can minimize the time the MCU spends on waiting for non-responsive ALDs by applying strict AISG compliance for response timing of ALDs.

If you have problems detecting ALDs from other manufacturers in your system, you can set the device scan speed to “Slow”. This will force the MCU to try several different device scan procedures. (The reason for the existence of different device scan procedures is that the definition of this procedure in the AISG specification is ambiguous and can be interpreted in different ways by different ALD manufacturers.)

Select the web page Devices → ALD List. A list of the connected ALDs is displayed. Under Device scan, set the following parameters:

then click Start Device Scan to cause the MCU to scan for the devices.

Switching between AISGV1.1 and AISGV2.0in order to speed up scans and parameter updates, it may be necessary to have all of your ALDs set to AISGV1.1 or to AISGV2.0. The Powerwave MCU includes a feature that allows you to switch all connected AISG devices (which can switch) between the two versions.To switch all ALD devices to a specific AISG version, follow the steps below.

AISG Version

Select the appropriate AISG version that you wish to scan for.

• Select AISGV1.1 to scan for only AISGV1.1 compliant devices.

• Select AISGV2.0 to scan for only AISGV2 compliant devices.

• Select AISGV1.1+AISGV2.0 to scan for both types of devices.

Strict AISG Response

Compliance

Select if AISG-compliant response timing should be applied.

• Yes (Faster): The ALDs must start transmitting their response within 10 ms, and the entire HDLC frame must be received within 104 ms. The MCU will always wait up to 140 ms for reception of an HDLC frame. The MCU will check if at least one octet has been received after 10 ms. If not, the MCU assumes that the ALD will not respond.

• No (Slower): The MCU will not require the ALDs to start transmitting their response within the required time. (If you experience communication problems, this setting might solve the problem.)

Device Scan

Speed

Select the device scan speed.

• Fast: The device scan will be performed using a procedure that will detect all Powerwave AISG equipment (and most equipment from other manufacturers).

• Slow: The MCU will try all possible device scan procedures. (This option should only be used if the previous option fails to produce a valid list of ALDs.)

Setting the Electrical Tilt of a RET or i-RET Unit with MCU Remote Electrical Tilt (RET)

3-46 044-05288 Rev C

Setting the Electrical Tilt of a RET or i-RET Unit with MCUThe MCU provides an option for scheduling one or more tilt set tasks on RET/3GPP devices on the ALD list page. The MCU automatically places a completion notice in the event log when the tilt set task is complete. In the MCU, scheduled task details are maintained in Flash memory to avoid data loss during a MCU reboot operation. Each scheduled task is considered an individual record containing the following details:

❑ ALD Address

❑ Tilt values needs to be set

❑ Scheduled Date and time for setting tilt

❑ Status of the task.

❑ Subunit information for 3GPP device

To schedule a MCU tilt set task, follow the steps below.

1. Select Devices → ALD List, then select Schedule Tilt from the Commands list..

The Schedule Tilt window displays.

2. Enter the tilt value in degrees.(For information on how the electrical tilt value is defined, refer to the AISG specification (Ref. [1])

MCU/Antenna Tilt Settings and XML File Generation Remote Electrical Tilt (RET)

3-48 044-05288 Rev C

MCU/Antenna Tilt Settings and XML File GenerationThis feature enables the MCU to generate an XML file for each tilt change. The MCU will generate and upload the XML file to a designated FTP site. This XML file can be used as a base file for generating analysis reports.

The XML files contain the following information:

❑ (Sitename)_(antenna position)_(band)_(date)_(Time).xml

❑ Date Format: DDMMMYYYY

❑ Time Format: HHMMSS (Time in 24 hour Format)

All the above values are retrieved from the MIB to generate the XML file name. See below for an example of the XML file format.

The above parameters are available as part of the MCU-MIB, AISG-MIB, RET-MIB and 3GPP-MIB. These details are used to generate the analysis report. Since there is not enough memory to store the XML file, the MCU must be set up to store the file in an FTP site. See the following section for details.

Downloading and Installing SoftwareNew software for the MCU and the ALDs can be downloaded from a remote server via FTP or HTTP. The server can be located anywhere in the management network or on a local PC.

When you have downloaded new MCU software, you can restart the MCU and swap to the new software to verify it. When you have verified that the new software is functioning correctly, you must validate the new software in order to install it permanently in the MCU. The old software is then erased from the MCU. However, if you don’t want to validate the new software you can revert to the old software.

ALDs can only contain one software version at a time. This means that you cannot revert to the old software once you have downloaded new software to an ALD.

If the image size of the latest downloaded ALD software is smaller than 128 kB, a copy of this software is cached in the MCU. This speeds up the subsequent download of software to ALDs of the same type.

Before you can configure a RET System you must make sure you have access to files containing correct configuration data for the RET modules. Antenna hex files are available at http://www.powerwave.com/retconfigfiles.asp. Contact Powerwave Technical Support if you encounter any issues or have additional questions.

NOTE If the MCU is restarted before you have validated the new software, the old software will automatically be reinstalled.

FTP Server Setup and MCU Software Updating

Installing the FTP server

If an FTP server is not available on your PC, you must download one. Powerwave recommends a free of use, open source product called FileZilla. It can be found at http://filezilla.sourceforge.net/.

1. Download the open source (free) FTP server FileZilla from http://prdownloads.sourceforge.net/filezilla/FileZilla_Server_0_9_3.exe?download

2. Run the downloaded program to start the installation.3. Click I Agree to the licence agreement.4. Choose Standard as the type of install and click Next.5. Enter, or browse the destination folder or use the recommended one and click Next.6. The next screen lets you decide how the FTP server should be started. The default is having the

server started automatically with windows and run as a service. If you later don’t need the server, it can be stopped by the Windows Administrative Tools found in the Control Panel. The other options should be left as they are. Finally click Install which will start the copy process.

7. When installation says “Completed”, click Close to exit installation program. The installed FTP server will be started automatically.

Configuring the FTP server1. In the pop-up window, click OK to continue.2. Create a folder (using Windows explorer or similar) where the MCU software can be placed. For

example c:\mcu.3. Contact Powerwave Technical Support as described at the end of this chapter and request a

copy of the latest MCU software. Copy both the image (*.img) and the checksum file (*.img.sum) to the c:\mcu folder.

4. Go back to the FTP server window and click edit and choose groups.5. On the “General” page, click Add and enter a description for this group, for example “MCU

software” and then click OK.6. Select the Shared folders page and click on the left most Add button to add a folder.7. Choose the folder c:\mcu and click OK.8. In the directory list, select the folder just added and click on Read in the Files form, and List and

+Subdirs in the Directories form to set permissions of this folder on the FTP server.9. Close the Group configuration screen by clicking on OK.10. Choose the menu item Edit once again, and select Users.11. On the General page, click Add to add a user.12. Enter the user name anonymous.13. In the list User should be member of the following group below, highlight the group MCU

software and then click on OK.14. Close the User configuration screen by clicking on OK.15. The FTP server is now configured and accepting file transfers by the user “anonymous”.

Updating the MCU Software1. Navigate in your web browser to the IP address of the MCU to be updated.2. Log in with “Level4” and the corresponding password.3. Click on General tab, and choose MCU SW Download.4. Select ftp as download service and enter the name or IP address of the computer you’ve installed

the FTP server on. The IP address can be found by starting a Command Prompt on the Windows computer and run the command ipconfig.

5. Enter the file name of the MCU software image (for instance “pw_mcu_software.img”) (same file name as used in Configuring the FTP server, step 3).

6. Enter “anonymous” as user name and leave the password blank. Then click Set.7. When the page has been reloaded, click on Start Download.8. After the download has finished, click on Swap to new SW. The MCU will then reboot with the

Network Management Remote Electrical Tilt (RET)

3-58 044-05288 Rev C

Network Management

Configuring IP AddressesIP addresses may be either static or dynamic. Static IP addresses are permanent. Dynamic IP addresses are only allocated for the duration of each communication session, or for some other specified amount of time. Once the host disconnects from the network, the dynamic IP address goes back into the IP address pool and can be assigned to another user. In a network with dynamic IP addresses, a DHCP server allocates all IP addresses upon DHCP requests from the hosts.

To setup static IP addresses, select Network → IP Addresses. The web page for configuration of IP addresses opens.

If you are setting up an IP address on the Site LAN port, make sure that Use DHCP is not checked for this port.

In the table IP Address Configuration, enter an IP address and a subnet mask for the Local LAN and/or Site LAN port and click Set.

If you want to configure the default gateway, you can do this before you continue to the next step and restart the MCU; refer to the Configuring IP Routing section in this chapter.

Scroll down to the bottom of the web page and click Restart MCU.

Page 81: Remote Electrical Tilt (RET)

Remote Electrical Tilt (RET) Network Management

044-05288 Rev C 3-59

To setup a dynamic IP address on the Site LAN port of the MCU, select Network → IP Addresses. The web page for configuration of IP addresses opens.

To make the MCU obtain a dynamic IP address from the DHCP server on the site LAN, check Use DHCP for the Site LAN port and click Set.

Scroll down to the bottom of the web page and click Restart MCU.

NOTE The values on IP address, subnet mask and default gateway further down on the web page (see Configuring IP Routing) are now greyed out and will be overridden by values obtained from the DHCP server on the site LAN.

Page 82: Remote Electrical Tilt (RET)

Configuring IP Routing Remote Electrical Tilt (RET)

3-60 044-05288 Rev C

This page intentionally left blank

Configuring IP RoutingIn a network using static IP addresses, you can configure the default gateway for accessing other networks. A “gateway” is a network point that acts as an entrance to another network. The computers that control traffic within your network are gateway nodes.

To setup a default gateway, select Network → IP Addresses. The web page for configuration of IP addresses is displayed.

In the Default Gateway Configuration table, enter the IP address of the default gateway in the Value field and click Set.

If you want to configure static IP addresses ("Static IP Addresses" on page 29) you can do this before you continue to the next step and restart the MCU.

Scroll down to the bottom of the web page and click Restart MCU.

NOTE If you have configured the MCU to use DHCP on the Site LAN port (see "Dynamic IP Address on the Site LAN Port of the MCU" on page 30), the default gateway is obtained from the DHCP server and can not be configured manually.

Remote Electrical Tilt (RET) Configuring IP Forwarding

044-05288 Rev C 3-61

Configuring IP ForwardingThe MCU forwards any IP packets received on the Local LAN port that are addressed to other hosts in the management network. This means that computers connected to the Local LAN port of an MCU can communicate with other equipment connected to the site LAN. If IP forwarding is not activated in your version of the software, contact the Powerwave Technical Help desk as described at the end of this chapter, and request an upgrade to the newest software version.

Configuring SNMP SettingsThe MCU supports SNMP v1, v2 and v3. It is capable of sending SNMP traps to notify an SNMP manager about certain events. It can generate traps to up to eight (8) SNMP managers simultaneously.

To configure SNMP traps, select Network → SNMP Traps. The web page for configuration of SNMP traps is displayed.

Configure the following parameters for each SNMP manager the MCU should send traps to:

Click Set.

NOTE It is not possible to communicate with equipment on the site LAN via a PPP connection to the RS-232 port.

Destination Enter the IP address or host name of the SNMP manager.

Community Enter the community that should be used for the SNMP traps.

Confirm community Enter the community once more, to ensure a correct configuration.

Enabled If you want the MCU to send SNMP traps to this destination, select Yes.

Trap version Select the SNMP version the traps should be sent in.
