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:
1.
Removing the ASN component tray
2.
Removing DRAM SIMMs
3.

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.
Danger:
Due to high-energy hazards, only qualified service personnel are
permitted to install or replace components in an ASN.
