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

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:

Installing the Memory Module

Complete the steps in this chapter to upgrade or replace the dynamic random access memory (DRAM) in an ARN. The ARN base module contains one connector for a streamlined inline memory module (SIMM).

To physically install a memory SIMM, you

Open the ARN enclosure to access the component tray.

Attach an antistatic wrist strap.

Caution:

antistatic strap whenever you remove, install, or handle printed circuit boards.

Remove the existing SIMM form the ARN base module.

Install the replacement or upgrade SIMM.

Close the ARN.

Reconnect the ARN to the network.

Opening the ARN

To open the enclosure and expose the base module:

Be sure that the ARN power switch is turned off (0).

Unplug the power cable from the wall receptacle and then fr om the ARN back panel (F

If present, unplug the redundant power supply cable.

Remove any console cabling from the back panel.

You receive an antistatic wrist strap with the ARN system and with the upgrade module shipment. Refer to the instructions in the wrist strap bag.

The antistatic wrist strap directs the discharge of static electricity from your body to the router chassis, thereby avoiding discharge to sensitive electronic components.

If the LEDs do not light in this sequence, the network administrator can refer to Conﬁguring Remote Access to help troubleshoot the problem.

Note: If the ARN does not contain an expansion module, an adapter module, a

redundant power supply, a data collection module, or a Flash card, the LEDs associated with these components remain off.

If you need additional assistance, contact your local Bay Networks Technical Response Center.

Your Next Step

To reconnect the ARN to the network, you need only reboot a valid conﬁguration ﬁle. Refer to Installing and Operating BayStack ARN Routers or to the Conﬁguring Remote Access guide for instructions.

Contact your network administrator if you need additional information.
