Hardware options installation 33
CAUTION: To avoid damage to the hard drives, memory, and other system components, the air
baffle, drive blanks, and access panel must be installed when the server is powered up.
NOTE: The server does not support Elpida 1G/2G/4G UDIMM memory.
1. Power down the server (on page 19).
2. Remove the access panel ("Removing the access panel" on page 20).
3. Open the DIMM slot latches.
4. Install the DIMM.
5. Install the access panel ("Installing the access panel" on page 21).
6. Power on the server ("Power up the server" on page 19, "Powering up and configuring the server" on
page 29).
Memory configuration
To optimize server availability, the server supports Advanced ECC This feature provides the greatest memory
capacity for a given DIMM size, while providing up to 8-bit error correction, depending on the specific
DIMM type. This mode is the default option for this server.
Advanced Memory Protection options are configured in RBSU. If the requested AMP mode is not supported
by the installed DIMM configuration, the server boots in Advanced ECC mode. For more information, see
"HP ROM-Based Setup Utility (on page 65)."
For the latest memory configuration information, see the QuickSpecs on the HP website
(http://www.hp.com).
ECC memory configuration
ECC memory is the default memory protection mode for this server. Standard ECC can correct single-bit
memory errors and detect multi-bit memory errors. When multi-bit errors are detected by using Standard
ECC, the error is sent to the server and causes the server to halt.
