Note:

The Canadian Department of Communications label identiﬁes certiﬁed equipment. The certiﬁcation means that the equipment meets certain telecommunications network protective, operational 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 a representative 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:

inspection authority, or electrician, as appropriate.

Notice:

terminal device provides an indication of the maximum number of terminals allowed to be connected to a telephone interface. The termination on an interface may consist of any combination of devices subject only to the requirement that the sum of the RENs of all the devices does not exceed 5.0. The REN is located on the “FCC Rules P art 68” label located on the bracket of the module, or on the back of the unit.

Note:

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 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 débranchement 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:

aux pouvoirs de réglementation en cause ou à un électricien, selon le cas.

Installing the HSSI Net Module in an ASN Platform

Removing the ASN Component Tray

You need a Phillips screwdriver to complete this procedure. To remove the ASN component tray:

Turn off the ASN.

Detach all cables, including the power cable, from the ASN back panel. Using a Phillips screwdriver, loosen the two captive screws that fasten the

tray to the chassis (Figure 1-1).

Pull out the two captive screws and gently slide the tray out of the

chassis a few inches (F

Hold the sides and bottom of the tray to support it as you slide it out; try to keep the tray level.

Place the tray on a sturdy work surface.

Installing the HSSI Net Module in an ASN Platform

Attaching the Antistatic Wrist Strap

The ASN comes with an antistatic wrist strap. The antistatic wrist strap directs the discharge of static electricity from your body to the chassis of the ASN, thereby protecting sensitive electronic components. You must wear the antistatic wrist strap whenever you handle the net module.

Caution:

Electrostatic discharge can damage the hardware. Follow the procedure in this section to protect your equipment.

To attach the antistatic wrist strap:

Remove the wrist strap from its package.

Place the looped end of the strap around your wrist.

Adjust the strap so that it ﬁts snugly on your wrist.

Attach the alligator clip at the other end of the wrist strap to any unpainted, metal surface on the component tray.

Removing a Filler Bracket

Filler brackets cover empty ASN net module positions and the openings above positions 1 and 3 (F the ﬁller brackets from the openings above positions 1 and 3, and from the position in which you want to install the net module.

Note:

This guide refers to the area where the net module ports are located as the “back end” of the component tray. To perform maintenance tasks on the ASN components, you face the back end of the tray.

Before you install a net module, note the following:

• To access position 2 or 4, you must remove the ﬁller bracket and net module

(if any) above it. See the sections “Remo “Remo

• To install the net module in the position from which you just removed a net

module, you must ﬁrst delete the old net module from the ASN’s conﬁguration ﬁle; then, install the new net module in the chassis. See Conﬁguring and Managing Routers with Site Manager for more information.

To install a net module:

1. Align the slots in the net module bracket with the metal tabs in the net

module position you want to use (F

Do not rest the bracket on the metal tabs. Doing so makes it difﬁcult to align the net module connector with the connector on the ASN system board.

F (Fail) Lights during the ASN power-up sequence and ﬂashes during

diagnostic testing. Turns off after the diagnostic testing completes successfully and the ASN boots.

This LED remains on if the net module or any connector on the net module fails diagnostic testing. In this case, the Diag LED on the ASN front panel also lights.

Requirements for European Operation

This appendix provides technical speciﬁcations and notes for operating the HSSI net module in Europe.

Installation Requirements

The net 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.

Appendix B

Installation of the HSSI net modules in an ASN will satisfy the conditions stated in this appendix. The ASN is supplied under the terms of General Approval No. NS/G/1234/J/100003.

Power Requirements

The HSSI net modules draw power from the host chassis. Table B-1 lists the power requirements.

117406-A Rev. A B-1

Installing the HSSI Net Module in an ASN Platform

The power drawn from the host chassis combined with that required for any other net modules and accessories must not exceed the power rating of the host chassis.

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

Clearance and Creepage Distances

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

• The host chassis in which it is installed

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

chassis backplane, where no minimum distance applies.

2.6 mm 3.0 (4.8) mm Up to 125 V rms or VDC

4.0 mm 5.0 (8.0) mm Up to 250 V rms or VDC

4.0 mm 6.4 (10.0) mm Up to 300 V rms or VDC

Parts of the Host or Expansion Card

The creepage distances apply to a typical ofﬁce en vironment. If the host chassis is exposed to conductive pollution or dry nonconducti ve pollution that could become conductive due to condensation, the creepage distances shown in parentheses in

able B-2 apply.

B-2 117406-A Rev. A

Requirements for European Operation

You determine the clearance and creepage distances between adjacent points as follows (F

igure 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.
