Installing ARE Memory Upgrade Modules

This document describes how to install Bay Networks 32 MB or 64 MB memory upgrade modules on an ATM Routing Engine (ARE) processor module.

The memory upgrade is supported by BayRS Version 12.00 and later. To install the memory upgrade modules, you must:

• Attach the antistatic wrist strap.

• Remove the existing virtual buffer memory (VBM) module, if one is installed.

• Install the new VBM module.

• Remove the existing single inline memory modules (SIMMs).

• Install the new SIMMs.

• Attach the upgrade label.

This document describes each of these tasks.

Required Tools

To install the memory upgrade modules, you need the following tools:

• Phillips screwdriver

• Antistatic wrist strap, which comes with the upgrade kit

Attaching the Antistatic Wrist Strap

You will find a disposable antistatic wrist strap with each upgrade kit. The antistatic wrist strap directs the discharge of static electricity from your body to the chassis of the BN router, thereby avoiding discharge to sensitive electronic components.

You must wear the antistatic strap whenever you remove, install, and handle the

VBM module or SIMMs.

To attach the antistatic wrist strap:

1.

2.

3.

Remove the strap from the upgrade kit.

Slip the wrist strap loop over your hand and tighten it snugly around your wrist.

Attach the alligator clip to the frame of the router.

You can now safely perform the upgrade procedure.

Installing ARE Memory Upgrade Modules

Removing the Virtual Buffer Memory Module

If you are upgrading an ARE processor module from 16 MB to 32 MB or 64 MB, you must first remove the existing VBM module before you can install the new one.

If you are upgrading from 8 MB to 32 MB, there is no VBM module to remove. In this case, go to the next section, “Installing the Virtual Buffer Memory Module.”

To remove the existing VBM module, you must first remove the ARE processor module from the router. Refer to Installing and Maintaining BN Routers for instructions on replacing a FRE

®

/FRE-2 module.

To remove the VBM module:

1.

Turn the ARE module over (component side down) and place it gently on your work surface.

2.

Remove the Phillips screws from each of the four mounting holes.

Figure 1 shows the location of the 4 Phillips screws.

Follow the steps in the next section to install the new VBM module.

Installing the Virtual Buffer Memory Module

If you have not already done so, remove the ARE processor module from the router. Refer to Installing and Maintaining BN Routers for instructions on replacing a FRE/FRE-2 module.

To install the VBM module:

1.

Align the two connectors on the VBM module with the connectors on the

ARE processor module. At the same time, be sure to align the standoffs on the underside of the VBM module with the mounting holes on the

ARE module. Then press the VBM module into place.
