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.

Attach an antistatic wrist strap before proceeding.

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.

Proceed as follows:

Figure 1-13. ARN Base Module Diagnostic LEDs

When you power on the ARN, the following sequence of front panel LED activity should occur:

• All base module LEDs light momentarily; this tests that the LEDs are operational.

• The Run, Boot, and Fail LEDs count through a short, initial startup sequence.

114206 Rev. A 1-13

Installing an Ethernet RMON DCM in a BayStack ARN Router

• The Pwr (power) LED lights and remains on.

• The Run LED be gins ﬂashing and continues to ﬂash until the ARN completes all diagnostic tests.

• As the diagnostic procedure tests each module, the LED representing that module ﬂashes slowly. If the module passes its diagnostic test, the LED remains on. If the module fails its diagnostic test, the Fail LED remains on and the module LED ﬂashes rapidly.

• After completing the diagnostic testing procedure, the boot process begins. The Run and Boot LEDs indicate the boot status as shown in T

able 1-1.

• After the boot process completes, the Run LED lights and the Boot LED turns off, indicating that the ARN is operational.

If the LEDs on the ARN light in this sequence, your upgrade is successful. Contact the network administrator to verify that the ARN is now connected to the network.

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.

To use the RMON data collection features of the newly-installed Ethernet DCM, you must

1. Modify the ARN conﬁg ﬁle to support the base or expansion Ethernet module

with DCM.

• To use the ARN installation script (arn_inst.bat), refer to Installing and

• To use the Conﬁguration Manager, refer to Conﬁguring Routers and to

2. Enable the DCM middleware (DCMMW).

Complete the steps in this chapter if you need to replace the SIMM on an Ethernet DCM. T

Note: These instructions assume that you have already removed the DCM

from the ARN base module, as described in Chapter 1.

able 2-1, at the end of this chapter, lists recommended SIMMs.

Removing an Installed SIMM

To remove the existing SIMM from an Ethernet DCM:

1. Look at the connector side of the DCM and identify the SIMM connector

and installed SIMM near the edge of the board (F

Note the spring latch at each end of the SIMM connector.

Carefully press outward on the two spring latches until the SIMM ejects

from the locking studs (F

Apply simultaneous pressure to both spring latches.

Rotate the SIMM upward and lift it out of its socket (Figure 2-3).

Figure 2-3. Removing the SIMM

As you remov e the SIMM, note the location and orientation of the SIMM

guide notch on one end of the SIMM connector edge (F

igure 2-4).

When you install the replacement SIMM, the guide notch must match the position of the guide notch on the SIMM you just removed.

Place the removed SIMM in an antistatic bag, or set it on an antistatic

mat.

Installing a DCM SIMM

1. Hold the replacement SIMM by its top corners, away from the connector

edge. Orient the guide notch as noted in Step 4

2. Slip the SIMM into the connector socket and push in gently to seat the

SIMM ﬁrmly in the socket (F

igure 2-5).

Caution: The SIMM is keyed with the guide notch to prevent incorrect

insertion. Do not force the SIMM if it does not go easily into the socket.

3. Tilt the SIMM down into its locked position (Figure 2-6).

You may hear a “click” as the spring latches engage the ends of the SIMM.

Caution: It is normal to feel a slight resistance as the SIMM comes to its

locked position, but be careful not to use too much force. It is easy to damage the SIMM socket by forcing it into the locked position.

Figure 2-6. Securing the New SIMM

The ﬁnal SIMM position is horizontal to the DCM printed circuit board.

4. If the SIMM does not lock, remove it, check the orientation of the guide

notch, reinsert the SIMM, and wiggle it gently as you press it into the socket. Then try again to tilt the SIMM into its locked position.
