Canada CS-03 Rules and Regulations
Note: The Canadian Department of Communications label identifies certified equipment. The certification means that the equipment meets certain telecommunications network protective operations and safety requirements. The
Department does not guarantee the equipment will operate to the user's satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. In some cases, the company's inside wiring associated with a single line individual service may be extended by means of a certified connector assembly (telephone extension cord). The customer should be aware that compliance with the above conditions may not prevent the degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.
Caution: Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate.
Canada CS-03 -- Règles et règlements
Note: L’étiquette du ministère des Communications du Canada indique que l’appareillage est certifié, c’est-à-dire qu’il respecte certaines exigences de sécurité et de fonctionnement visant les réseaux de télécommunications. Le ministère ne garantit pas que l’appareillage fonctionnera à la satisfaction de l’utilisateur.
Avant d’installer l’appareillage, s’assurer qu’il peut être branché aux installations du service de télécommunications local. L’appareillage doit aussi être raccordé selon des méthodes acceptées. Dans certains cas, le câblage interne du service de télécommunications utilisé pour une ligne individuelle peut être allongé au moyen d’un connecteur certifié
(prolongateur téléphonique). Le client doit toutefois prendre note qu’une telle installation n’assure pas un service parfait en tout temps.
Les réparations de l’appareillage certifié devraient être confiées à un service d’entretien canadien désigné par le fournisseur. En cas de réparation ou de modification effectuées par l’utilisateur ou de mauvais fonctionnement de l’appareillage, le service de télécommunications peut demander le débranchment de l’appareillage.
Pour leur propre sécurité, les utilisateurs devraient s’assurer que les mises à la terre des lignes de distribution d’électricité, des lignes téléphoniques et de la tuyauterie métallique interne sont raccordées ensemble. Cette mesure de sécurité est particulièrement importante en milieu rural.
Attention: Les utilisateurs ne doivent pas procéder à ces raccordements eux-mêmes mais doivent plutôt faire appel aux pouvoirs de réglementation en cause ou à un électricien, selon le cas.

Chapter 1
Preparing for Installation
Note: In this guide, the term FDDI link module includes FDDI Multimode,
Single Mode, and Hybrid link modules, unless referring to a specific model.
Depending on your configuration, complete these preliminary tasks as needed to install the link module:
• Choose a slot
• Remove a link module
Note: There are no user-configurable jumpers on FDDI link modules.
Changing any jumper settings on these link modules can jeopardize the module functioning.
Choosing a Slot
You can install the FDDI link module in
• Slots 2 through 5 in the BLN platform
•
Slots 2 through 5 in the BLN-2 platform (Figure 1-2)
•
Slots 1 through 6 and Slots 8 through 14 in the BCN platform (Figure 1-3)

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 FDDI 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.
Refer to Configuring Routers if you use router software or Administration Guide if you use BayStream software for instructions on editing a configuration file and deleting circuits.
114950-A Rev. A 1-3
Installing FDDI Link Modules in BN Platforms
The Backbone Node hot-swap feature allows you to remove or replace a link module with the chassis power on or off.
Danger: Do not remove more than two adjacent modules with the power on.
When you remove a link module with the power on, the services that slot provides become disrupted. 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.
2.
Disconnect any exterior cables from the link module.
Attach an antistatic wrist strap.
BN platforms and link modules ship with an antistatic wrist strap. You must wear one of these straps when accessing components on BN platforms. The antistatic wrist strap directs the discharge of static electricity from your body to the chassis, thereby avoiding discharge and possible damage to sensitive electronic components.
Caution: Electrostatic discharge can damage hardware. Always use the antistatic wrist strap when handling any component on your BN platform.
3.
4.
5.
Loosen the captive screw on each end of the module.
Grasp the sides of the module and pull it out of the slot.
Place the module in an antistatic protective bag.
1-4 114950-A Rev. A
Chapter 2
Installing the Link Module
Complete the steps in this chapter to install the FDDI link module in your BLN,
BLN-2, or BCN platform.
Inserting the Link Module
Install the link module in the BLN, BLN-2, or BCN platform as follows:
1.
Attach an antistatic wrist strap.
BN platforms and link modules ship with an antistatic wrist strap. You must wear one of these straps whenever you access components in a BN platform.
The antistatic wrist strap directs the discharge of static electricity from your body to the chassis, thereby avoiding discharge and possible damage to sensitive electronic components.
Caution: Electrostatic discharge can damage hardware. Always use the antistatic wrist strap when handling any router components.
3.
4.
2.
Slide the module into the appropriate slot, using the slot card guides.
Refer to Figure 1-1 (BLN), 1-2 (BLN-2), or 1-3 (BCN) for slot locations.
Insert the module until its connector panel touches the router back panel.
Secure the captive screw on each end of the module

Chapter 3
Checking Status Indicators
This chapter describes the status indicator lights (LEDs) on the FDDI link modules. Use the LEDs to verify that the link module is operating after installation.
Note: We recommend that you issue the diags command to the associated slot, using the Bay 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.) Otherwise, the link module FAIL LED will remain lit, indicating that diagnostics have not run on the Intelligent Link Interface (ILI). However, even if you do not issue the diags command, the link module initializes and becomes operational as long as the board functions properly and contains the correct interface configurations.
Figure 3-1 shows the LEDs on the FDDI link module. The groups of LEDs
labeled A and B indicate the status of physical connectors A and B as Table 3-1
describes.
