HP ProLiant DL580 Generation 3 Server Maintenance and Service Guide
IMPORTANT: To reconfigure the memory mode after initial setup,
you must reboot the system, enter RBSU, and select the desired AMP
mode.
Memory boards and DIMMs
Memory board and DIMM removal and replacement procedures can be either
hot-replace or non-hot-plug, depending on how the server is configured. Hot-
replace enables failed or degraded DIMMs to be replaced while the server is
running, and has no operating system requirements.
When the server is configured for hot-plug mirrored memory or hot-plug RAID
memory, you can perform a hot-replacement procedure without powering down
the server or experiencing server downtime:
1.
Remove a memory board ("Removing a memory board" on page
75
,
"Removing a memory board (non-hot-plug)" on page
73
).
2.
Replace failed or degraded DIMMs ("Removing DIMMs" on page
76
).
3.
Reinstall the memory board in the slot from which it was removed.
The replacement procedures in this section apply to both hot-replace and non-
hot-plug memory procedures, except as noted.
IMPORTANT: Be sure to power down the server when performing
board removal procedures in a server that is not configured for
Advanced ECC, hot-plug mirrored memory, or hot-plug RAID memory.
Observe the following warnings when performing a hot-plug replacement
procedure.
WARNING: Always comply with all electrostatic and thermal
guidelines to prevent bodily injury and ensure a properly
functioning system when performing hot-plug operations.
WARNING: To prevent personal injury from hazardous
energy:
•
Remove watches, rings, or other metal objects.
•
Use tools with insulated handles.
•
Do not place tools or metal parts on top of batteries.
