Technical Manual 76.8171150H 71150H Unified Packet Fabric Module

1. General Information

1.01 This module practice describes the features and circuitry of the 71150H UFAB. Refer to Figure 1, page 1.

1.02 The UFAB is a single-slot module used in applications with the High Capacity Switch Shelf (HCSS). The UFAB provides the following general functions:

• high speed backplane interface supporting fourteen 20 Gbps module slots

• SONET and SDH switching between modules

• unicast and multicast address management

1.03 The HCSS requires three UFABs. 2:1 UFABs provide protected switching for the 280 Gbps of traffic supported on the HCSS. The UFABs provide load sharing across switch devices and port modules.

1.04 The UFABs contain packet-based switch devices. The three UFABs provide the center stage switch for the SONET and SDH traffic that is emulated by the port modules. UFAB equipment redundancy and the protection of the switch function is enabled at the hardware level.

1.05 Each element in the switch fabric is a shared memory switch with a single priority queue per interface on the switch device. The traffic scheduler for each port is located on the port module at the egress side of the system. The arrival of a packet to an empty virtual output queue results in the transmission of a flow control message to the associated egress scheduler. The packet is segmented and transmitted as a series of constituent cells.

1.06 Because multiple serial links connect an ingress queue to an egress port, the constituent cells can be distributed over a number of links in a load sharing arrangement. The links available for load sharing are determined through reachability messages. The UFAB can distribute the cells of a packet over any number of switching planes.

1.07 In the HCSS architecture, the first and third switch stages are provided by the switch interface devices of the port module, while the center stage is provided by the switch devices on the UFAB. All switch interface devices connect to each switching plane in order to ensure non-blocking behavior. Each physical switching device can be configured with one or more logical switching planes.

Reason for Issue 1.08 Tellabs issues this module practice at Revision A to describe functionality for Tellabs 7100 Optical Transport System FP6.0.x.

3.04 2:1 UFABs provide protected switching for the 280 Gbps of traffic supported on the HCSS. The protection module constantly operating in working mode, and the system determines load sharing among all three UFABs.

3.05 The UFABs support up to 14 port modules in slots 2–8 and slots 12–18.

3.06 The UFABs require at least one controller module in slots 1 and 19.

Removal and Insertion

3.07 Visually inspect the 71150H UFAB upon arrival for possible damage incurred during shipment. If there is any damage, file a claim with the carrier immediately. If you have stored the module, visually inspect it again before installation.

Warning:

Always wear a static protection wriststrap while performing any procedures that require you to come in contact with the system. This includes touching modules, cabling, or the system in any way. Electrostatic Discharge (ESD) can damage system components resulting in a traffic affecting condition. Ensure that modules are stored in static preventive material.

Warning:

If the module connector pins are bent or broken, the module may not function as intended. The system operation will be affected. If, during installation, you encounter resistance before the front panel meets the shelf, do not force the module into place. Check the slot module guides, connectors, and clips to locate and remove any potential obstruction before proceeding.

Warning:

Failure to maintain proper module alignment during removal or insertion can cause circuit board component damage. Ensure that the module and circuit board components do not contact adjacent modules during installation or removal.

Removal3.08 To remove a module from a non-powered system, such as from a new system prior to power-up, proceed as follows. Refer to Figure 4, page 7.

__ 1. Using both hands, use the release tabs to open the top and bottom ejector clips and hold them in the open position.

__ 2. Use the ejector clips to slowly pull the module out of the slot.

Figure 4 Module Removal Method

Insertion3.09 To insert a module into a non-powered up system, such as into a new system prior to power-up, proceed as follows. Refer to Figure 5, page 8.

__ 1. Place the module into the module guides of its assigned slot position.

__ 2. Using both hands, use the release tabs to open the top and bottom ejector clips and hold them in the open position.

Note: Do not force the module into place. If the module does not slide and click easily into position, retract the module and verify that there is nothing obstructing its entry into the slot position on the shelf.

__ 3. Slide the module into place until it is firmly seated in the module back-plane connectors and the ejector clips located at the top and bottom of the module click into a closed position.

Functional Overview

4.03 The UFAB is a single-slot module used in applications with the High Capacity Switch Shelf (HCSS). The UFAB provides the following general functions:

• high speed backplane interface supporting fourteen 20 Gbps module slots

• SONET and SDH switching between modules

• unicast and multicast address management

4.04 The HCSS requires three UFABs. 2:1 UFABs provide protected switching for the 280 Gbps of traffic supported on the HCSS.

Microprocessor4.05 The microprocessor provides module control and communications, application flash, and application memory.

Backplane Interface4.06 The UFAB interfaces to the high speed backplane via 16 high speed interface connectors. Eight connectors are used to interface with universal slots 2-8 and 12-18. Another eight are reserved for future use.

Power4.07 The power supply convert the -48V power feed to the different voltages needed on the UFAB. The power supply also monitors voltages on every supply feed generated by the power converters. The power supply reports alarms in case of failure, and is protected against power reversal.

Switch Device4.08 The switch device consists of four self-routing switching elements. The fabric switches destination-routed and source-routed data cells and control cells. Once switched, both data and control cells are multiplexed over the output serial links.

4.09 The switch fabric supports unicast and multicast signals. The switch fabric also features internal input-to-output CRC checking, dynamic topology detection, and automatic fault detection and recovery using dynamic distribution and routing tables.

10. Module Repair and Return

General Repair and Return Information

10.01 Tellabs will repair or replace Tellabs products provided that the need for this repair or replacement arises from the ordinary use of the products as intended by the manufacturer or otherwise stated in Tellabs literature.

10.02 For more information about in-warranty and out-of-warranty repairs and returns, see the Tellabs Global Repair and Return Policy, available on the Tellabs website at www.tellabs.com. Click the Services and Support link and navigate to Technical Support.

10.03 Complete any applicable troubleshooting procedures to troubleshoot the module. If you suspect the module is defective, follow the procedures in Section 8, Module Replacement and After-Sale Technical Support, page 12 to replace the faulty module with a new module and conduct the test again.

• If the substitute operates correctly, the original should be considered defective and returned to Tellabs as explained in Contacting Tellabs Repair Centers, page 14.

• If normal troubleshooting procedures do not solve the problem, contact Tellabs Technical Support Center.

10.04 Tellabs strongly recommends that no internal (component-level) testing or repairs be attempted on the equipment. Unauthorized testing or repairs may void the warranty. Also, if the equipment is part of a registered system, unauthorized repairs result in noncompliance with Parts 15 and/or 68 of the FCC Rules and Regulations.

10.05 Although repair service always includes an attempt to remove any permanent markings made by customers on Tellabs products, the success of such attempts cannot be guaranteed. Therefore, if equipment must be marked defective or bad, Tellabs recommends that it be done with non-permanent materials and, where appropriate, in a manner consistent with the correct handling of electrostatically sensitive devices.
