Memory
Installation, Removal, and Replacement Procedures
DIMM and memory board installation, removal, and replacement procedures can be
either hot-plug or non-hot-plug procedures, depending on how the server is
configured.

You cannot perform hot-plug procedures when the system is configured for:
— Advanced ECC memory (unless it is configured for Hot-Add memory)
— Online spare memory
— Single-board mirrored memory
You cannot perform hot-replace procedures when the system is configured for
advanced ECC memory.
You can perform a hot-replacement procedure when the server is configured for:
— Hot-plug mirrored memory, enabling you to replace failed or degraded
DIMMs without powering down the server
— Hot-Add functionality, which allows you to upgrade the amount of server
memory without powering down the server.
The replacement procedures in this section apply to both hot-plug and non-hot-plug
memory procedures, except as noted.
CAUTION: Be sure to power down the server when performing these procedures in
a server that is not configured for hot-plug mirrored memory or Hot-Add memory
functionality.
When the ProLiant DL580 Generation 2 server is configured for hot-plug mirrored
memory, you can perform a hot-replacement. Hot-replacement enables you to
remove a memory board, remove a failed or degraded memory, replace the DIMMs,
and reinstall the memory board, all without powering down the server or
experiencing server downtime.
