Installing ATM Link Modules and Routing Engines in BN Platforms How to Get Help If you purchased a service contract for your Nortel Networks product from a distributor or authorized reseller, contact the technical support staff for that distributor or reseller for assistance.
Chapter 1 Installing ATM Link Modules Note: In this guide, the term ATM link module includes all Nortel Networks ARE link modules (ARE OC-3, DS-3, E-3, and SONET/SDH) , unless referring to a specific model. The term does not include the ARE processor module. To install an ATM link module, complete these preliminary tasks as needed: • Choose a slot • Remove a link module • Configure jumper settings This chapter describes each of these tasks, as well as how to install the ATM link module.

Link Module Slots in a BCN Platform Removing a Link Module If there are no empty slots in your BN platform, you must remove a link module to install the ATM link module. When replacing a configured link module, you must delete all configured circuits (ports) on the slot so the BN platform software can properly configure the new link module.
Installing ATM Link Modules and Routing Engines in BN Platforms Removing a link module with the power on distrupts the services that slot provides. However, after the slot fails to receive packets, the other link modules in the chassis resynchronize their routing tables and continue uninterrupted. The procedure for removing a link module is the same for the BLN, BLN-2, and BCN platforms: 1. Disconnect any exterior cables from the link module. 2. Attach an antistatic wrist strap.

Chapter 2 Installing ARE Processor Modules To install an ARE processor module, you must first 1. Remove the front bezel of your BN platform. 2. Remove the electromagnetic compatibility (EMC) shield from the front panel to access the interior. 3. Choose a slot. 4. Remove the board retainer bracket (BLN and BLN-2 only). 5. Remove the air flow module (unless the slot you want to use already contains a processor module). 6.
Installing ATM Link Modules and Routing Engines in BN Platforms Removing the Front Bezel You must remove the BN platform front bezel (front cover) to access the interior. Note: Keep the front bezel on during normal operation to comply with air flow requirements. To remove the front bezel from the BLN (Figure 2-1) and BLN-2 (Figure 2-2): 1. Using both hands, pull the bottom of the front bezel forward. 2. Remove the bezel from the chassis.

Installing ARE Processor Modules Removing the EMC Shield You must remove the EMC shield to access the processor modules in BN platforms. Caution: Do not operate a BN platform with the EMC shield removed for more than 5 minutes. Without the EMC shield, the BN platform may overheat. In addition, the BCN contains temperature sensors that may not detect an overheating condition without the shield in place. To remove the EMC shield (Figure 2-4): 1. Attach an antistatic wrist strap.

Installing ATM Link Modules and Routing Engines in BN Platforms Removing the Board Retainer Bracket (BLN and BLN-2 Only) If you have a BLN or BLN-2 platform, remove the board retainer bracket shown earlier in Figure 2-5 (BLN) and Figure 2-6 (BLN-2): 1. Use a screwdriver to remove the screw connecting the board retainer bracket to the chassis. 2. Gently pull the bottom of the board retainer bracket to remove it.

Removing an Air Flow Module Removing a Processor Module Danger: A potential energy hazard exists during hot-swap service of processor modules. Do not remove more than two adjacent modules without powering off the BN platform. To remove a processor module: 1. Gently pull the inside of the board extractors at the end of the module toward you (Figure 2-10).

Slide the top of the board retainer bracket into its designated ridge and align the bottom of the bracket with the screw hole at the bottom of the chassis (refer to Figure 2-5 or 2-6). b. Using a screwdriver, secure the bracket to the chassis. Replace the EMC shield as follows (refer to Figure 2-4): a.
Chapter 3 Checking Status Indicators Check the LEDs on the ATM link modules or the ARE processor module to verify that a module is operating after installation. Note: We recommend that you issue the diags command to the associated slot, using the Nortel Networks Technician Interface, immediately after you insert a link module. (Refer to Using Technician Interface Software if you use router software or Troubleshooting and Testing if you use BayStream software.
