5.
Press the Escape key twice to go back to the main RBSU menu.
6. Press the F10 key, when prompted, to exit RBSU. The server reboots and tests all memory in the
system.
IMPORTANT: To reconfigure the memory mode after initial setup, you must reboot the system, enter RBSU,
and select an 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 58, "Removing a memory board
(non-hot-plug)" on page 57).
2. Replace failed or degraded DIMMs ("Removing DIMMs" on page 59).
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.
