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 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:

Chapter 1

Installing a CPU Memory Upgrade in the ASN

This chapter describes how to install a CPU memory upgrade in a Bay Networks® Access Stack Node (ASN). After you review the ASN SIMM types and attach the antistatic wrist strap, you will need a Phillips screwdriver to complete the following steps:

Reviewing the SIMM Types

The ASN uses SIMMs to provide

• Dynamic random access memory (DRAM).

• Tag memory, which adds a protection tag to individual memory locations. For example, a memory location might be tagged with write protection.

112944-B Rev. A

Installing a CPU Memory Upgrade in ASN and SN Platforms

The ASN supports conﬁgurations of 8, 16, and 32 MB of DRAM. T

The capacity of the SIMM you use for Tag memory depends on the DRAM conﬁguration. T

conﬁguration.

If you upgrade the DRAM, be sure to use the appropriate Tag SIMM.

Note:

Order No. 50027 does not require a Tag SIMM replacement.

Attaching the Antistatic Wrist Strap

You must wear an antistatic wrist strap whenever you remove, install, or handle a SIMM.

Caution:

in this section to protect your equipment from damage.

Electrostatic discharge can damage hardware. Follow the procedure

112944-B Rev. A

Installing a CPU Memory Upgrade in the ASN

To attach the antistatic wrist strap:

Remove the strap, alligator clip, and cable from the package.

Attach (snap) the snap end of the cable to the wrist strap.

Place the strap around your wrist, and adjust the strap to ensur e that the metal buckle inside the strap touches your skin.

Plug the jack at the other end of the cable into the opening on the alligator clip.

Attach the alligator clip to any unpainted metal surface on the component tray.

Removing the ASN Component Tray

Before you can upgrade memory in the ASN, you must remove the component tray from the ASN chassis. To remove the ASN component tray:

Turn off the ASN, and detach all cables from the back panel.

Using a Phillips screwdriver, loosen the two captive screws that fasten the tray to the chassis (F

igure 1-1).

112944-B Rev. A

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

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

Place the tray on a sturdy work surface.

Caution:

Do not touch any components or modules in the ASN until you ha ve attached the antistatic wrist strap. Refer to the section “ Attaching the Antistatic Wrist Strap.”

The net module ports are exposed at the back of the component tray. To perform maintenance tasks on the ASN components, face the back of the tray.

When you install DRAM SIMMs, make sure that the SIMMs are the same size. For example, you can install two 2-MB by 36 SIMMs for a 16-MB conﬁguration; howev er, do not install one 1-MB by 36 and one 2-MB by 36 SIMM.

Also, make sure that you are using the correct capacity Tag SIMM for your DRAM conﬁguration (refer to T

Reviewing the SIMM Types

The SN uses SIMMs to provide the following:

• Dynamic random access memory (DRAM).

• Tag memory, which adds a protection tag to individual memory locations. For example, a memory location might be tagged with write protection.

Installing a CPU Memory Upgrade in ASN and SN Platforms

The SN supports conﬁgurations of 16 and 32 MB of DRAM. Table 2-1 shows the DRAM SIMM requirements for each conﬁguration.

Number

Conﬁguration SIMM Capacity

16 MB 2 MB by 36 2 32 MB 4 MB by 36 2

of SIMMs

The capacity of the SIMM you use for Tag memory depends on the DRAM conﬁguration. T

able 2-2 shows the Tag SIMM requirements for each

conﬁguration.

Table 2-2. Tag SIMM Requirements

DRAM Conﬁguration Tag SIMM Capacity

16 MB 1 MB by 8 32 MB 4 MB by 8

If you upgrade the DRAM, be sure to use the appropriate Tag SIMM.

Attaching the Antistatic Wrist Strap

You must wear an antistatic wrist strap whenever you remove, install, or handle a SIMM.

Caution: Electrostatic discharge can damage hardware. Follow the procedure

in this section to protect your equipment from damage.

To attach the antistatic wrist strap:

1. Remove the strap, alligator clip, and cable from the package.

2. Attach (snap) the snap end of the cable to the wrist strap.

3. Place the strap around your wrist, and adjust the strap to ensur e that the

metal buckle inside the strap touches your skin.

Plug the jack at the other end of the cable into the opening on the

alligator clip.

5. Attach the alligator clip to any unpainted metal surface on the chassis.

Removing the Switch Node CPU Module

To remove the SN CPU module:

1. Turn off the Switch Node.

2. Disconnect any modem and console cables that are attached to the CPU

module.

3. Remove the ﬂash memory card from the PCMCIA slot by pressing the

eject button to the right of the slot (F

igure 2-1).

6. Pull the captive retaining screws toward you to pull the module partially

out of the chassis. Grasp the module by its edges to remove it from the chassis.

7. Place the module on an antistatic work surface.

Caution: Do not touch any components or modules in the Switch Node until

you have attached the antistatic wrist strap. Refer to the section “Attaching the Antistatic Wrist Strap.”

Labeling the Switch Node

After you perform the DRAM SIMM upgrade, label the SN CPU with a new Memory Size label. Af ﬁxing the new label is important because future repairs and upgrades will require that you correctly identify the current memory conﬁguration of your SN.

To label your SN:

1. Find the CPU Part Number label on the SN CPU (Figure 2-9).

The CPU Part Number label will read 114252-16 or 114252-32.

2. Apply the Memory Size label to the end of the CPU Part Number label,

making sure that you do not cover any portion of the bar code.

The Memory Size label should be next to the component reference designator C36 (F
