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.

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:

Removing a Link Module

If there are no empty slots in your BN platform, you must remove a link module to install the Sync 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 Synchronous 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 pro vides become disrupted. After the slot f ails 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:

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.

1-4

Caution: Electrostatic discharge can damage hardware. Always use the

antistatic wrist strap when handling any component on your BN platform.

Loosen the captive screw on each end of the module.

Grasp the sides of the module and pull it out of the slot.

5. Place the module in an antistatic protective bag.

114944-A Rev. A

Conﬁguring Jumper Settings

The Quad Sync link module (Order No. 5280) contains user-conﬁgurable jumper settings.

Note: The Octal Sync link module does not contain user-conﬁgurable jumpers

or switches. Also, depending on the model, your Octal Sync link module may have a hardware compression daughterboard. This daughterboard does not contain user-conﬁgurable jumpers or switches.

Figure 1-4 shows only the user-conﬁgurable jumpers on the Quad Sync link

module; changing the settings of any other jumpers on the link module can jeopardize module functioning.

Complete the steps in this chapter to install the Sync 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.

Chapter 2

Installing the Link Module

BN platforms and link modules ship with an antistatic wrist strap. You must wear one of these straps whenever you access components in a 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.

2. Using the slot card guides, slide the module into the appropriate slot until

the module’s connector panel touches the BN platform’s back panel.

Refer to Figure 1-1 (BLN), 1-2 (BLN-2), or 1-3 (BCN) in Chapter 1 for slot locations.

3. Secure the captive screw on each end of the module (Figure 2-1).

screws are the same on all link modules.

Checking Status Indicators

This chapter describes the status indicator lights (LEDs) on the Sync 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 becomes operational as long as the board functions properly and contains the correct interface conﬁgurations.

Requirements for European Operation

This appendix provides technical speciﬁcations and notes about operating the following link modules in Europe:

• Quad Sync (Order No. 5280, Part No. 102285)

• Octal Sync (Order No. 5008, Part No. 109871)

Installation Requirements

Appendix B

The link modules are approved only for installation in a host, and with host attachments, which are either type approved for such apparatus or, if supplied after March 1, 1989, are marked with or supplied with a statement that the host is supplied under the terms of General Approval No. NS/G/1234/J/100003.

Installation of the link modules in a BLN, BLN-2, or BCN platform will satisfy the conditions stated in this appendix. The BLN, BLN-2, and BCN platforms are supplied under the terms of General Approval NS/G/1234/J/100003.

Power Requirements

The link modules are powered from the host chassis and have the power requirements shown in T

Installing Synchronous Link Modules in BN Platforms

The power drawn from the host chassis, combined with the power needs of any other link modules and accessories, must be within the power rating of the host chassis.

You must install the link modules so as not to impair the integrity of the network protection from hazardous voltages used or generated internally by the host chassis.

Clearances and Creepage Distances

You must maintain the clearances and creepage distances (shown as X and Y, respectively, in T

• The host chassis in which it is installed

• Any adjacent link modules installed in the host chassis The exception to this rule is the edge connector, which is located in the host

chassis backplane, where no minimum distance applies.

The clearance and creepage distance between adjacent points should be checked as follows (Figure

B-1):

• The clearance distance (X) is the shortest distance between two points measured through the air.

• The creepage distance (Y) is the shortest distance between two points measured across a surface.
