Replacing DIMMs

This section includes the following topics:

•Memory Performance Guidelines and Population Rules, page 3-20

•DIMM Replacement Procedure, page 3-23

Caution DIMMs and their sockets are fragile and must be handled with care to avoid damage during installation.

Caution Cisco does not support 3rd-party DIMMs. Using non-Cisco DIMMs in the server might result in system problems or damage to the motherboard.

Note To ensure the best server performance, it is important that you are familiar with memory performance guidelines and population rules before you install or replace memory.
