All above with nominal 48V voltage input.

For the fuse ratings of the FPFA/B outputs, see section FPFA and FPFB interfaces below.

For transmission sub-module power consumption figures, see section Power require-

ments of transmission sub-modules.

2.2 Power requirements of transmission sub-modules

The typical power consumption of the transmission sub-modules is described in the

table below.

Power consumption depends on the equipment connected to the FTFA sub-module.

2.3 FPFA and FPFB interfaces

Power is distributed from Flexi Power Distribution and Fuses (FPFA and FPFB) to the

System Module. The FPFA is used with System Module rel. 1, whereas in System

Module rel. 2 it is replaced with the FPFB, which gives more power feeding capacity to

RF Modules. The FPFB is compatible with both System Module releases.

g If the total output power of an RF Module is more than 100W, the FPFB version of

the Flexi Power Distribution and Fuses module must be used with a rel. 1 System

Module. For example, in a 1+1+1 40W configuration the total output power is 120W

and therefore an FPFB is needed.

The FPFB does not have any circuit breakers but instead electrical fuses and a dedi-

cated power switch for the System Module. The fuse rates for the FPFA are:• A.101: RF1-3 20.0A, EXT 25.0A

• A.102 or later: RF1-3 20.0A, EXT 25.0A (System Module supplied via EXT circuit

breaker)

The fuse rates for the FPFB are:

• RF1-3 31.0A (+/-2A), EXT 25.0A (+/- 4.5A)

See the following figure for the location of the FPFA/B.

Figure 12 Location of the FPFA/B in the System Module

Inputs and outputs

A busbar input connector (with screw connection) must always be used for input con-

nections of the FPFA/B and when connecting power to the System Extension Module.

The multibeam connectors on the front panel must not be used as input to the FPFA/B.

The multibeam connectors are not hot-plug connectors. The power must be switched off

via the on/off switch on the FPFA/B front panel when connecting or disconnecting the

RF or System Extension Module to the FPFA/B.

There are two types of FPFAs available:

•

A101 version• A102, A103 or later

There are differences between these versions in the inner connections.

2.4 FPFA electrical connections

Note that there is a risk of short circuit. Connect the power cable as instructed.

FPFA version A101

Extension module power supply comes through the circuit breaker and extension

module power can be switched off via the circuit breaker. This must be done if the exten-

sion module is connected to the System Module to avoid hot-plug connection. This also

required when disconnecting from the System Module.

When pulling the EXT circuit breaker switch to off position, switch off the power supply

to the extension module. Power feed to the System Module is still on.

FPFA version A102, A103 or later

FPFA versions A102, A103 or later have a common power supply via the same circuit

breaker for the System Module and the System Extension Module. This means that the

same circuit breaker switch can be used to switch on and off the power to the System

Module and the System Extension Module.

g The System Module and extension modules are reset by pulling the EXT circuit

breaker on/off switch on the front panel.

When connecting the extension module to the System Module, switch off the circuitbreaker to avoid hot-plug connection to extension modules. After that, switch off the

System Module.

This is also required when disconnecting the extension module from the System

Module.

Flexi WCDMA BTS System Module Description System Module as an extension module

Id:0900d805805b6253

6 System Module as an extension moduleThe System Module can be used as a System Extension Module operating in a

baseband extension mode to add channel capacity. In this case, it is connected to the

System Module by connecting two optical cables and a DC cable. These items are

provided with Flexi System Extension Kit (FSKA).

When the System Module is used as a System Extension Module operating in a

baseband extension mode, a transmission sub-module is not installed. Instead, a

dummy transmission sub-module is installed to provide IP protection. This item is also

included in Flexi System Extension Kit (FSKA).

When the System Module is used as a System Extension Module operating in a

baseband extension mode, the only connectors that can be used are DC input and

optical interfaces from the System Module (with a few exceptions). Synchronisation is

provided by the System Module. For installation instructions, see section Installing

System Extension Module in the Installing Flexi WCDMA BTS Optional Itemsdocument.For commissioning instructions, see the Commissioning Flexi WCDMA BTS document.

When integrating the System Extension Module to Flexi WCDMA BTS, no commission-

ing is required. Once the System Extension Module has been connected to the System

Module and powered up, the auto detection functions of Flexi WCDMA BTS detect the

System Extension Module and connect the System Extension Module to the normal

operation of the BTS. As for software requirements, the auto detection requires that

WN3.3 or later BTS SW exists and is active both in the System Module and System

Extension Module to be connected to. However, support for the FSMC, FSMD and

FSME is introduced in WN5.0.

• The signal in MDR14 is asymmetric: connect the core of the coaxial cable to pin7 and cable shield to GND (e.g. pin 14).

• Testclk_out: 10MHz system clock (LVTTL)

• The signal comes from BTS OCXO which is used for air I/F generation => refer-

ence for the RF measurement equipment.

• Note: the BTS OCXO is not in the PLL mode to the Iub, the locking is very loose

due to air I/F stability reasons.

• The signal in MDR14 is asymmetric: connect the core of the coaxial cable to pin

11 and cable shield to GND (e.g. pin 10)

• GND: signal ground, for asymmetric signals
