To install or replace memory:
1 Follow the instructions in “Preventing static electricity discharge” on page 18.
2 Follow the instructions in “Opening the server case” on page 19.
3 Pull the plastic tabs (1) away from the sides of the memory module slot. If you are replacing
a memory module, lift the old memory module (2) out of the slot.
4 Align the notch on the new module with the notch in the memory module slot and press
the module firmly into the slot. The tabs on the sides of the memory slot should secure
the memory module automatically.
5 Follow the instructions in “Closing the server case” on page 24.
6 Restart your server and open the BIOS Setup utility. Verify the System Memory listed in
the Main menu. When you exit the BIOS Setup utility, make sure that the operating system
loads completely.
Memory online sparing
The chipset on the system board in the server supports memory online sparing, which can provide
a way to prevent data loss in case of DIMM failure. If a DIMM failure does occur, a DIMM fault
LED adjacent to the DIMM slot will light orange to indicate the failed memory module.
Using memory online sparing, one DIMM per channel (selectable in the BIOS setup utility) is used
as a memory spare (the spare DIMM must be equal to, or larger than, the largest DIMM in that
channel). If a DIMM begins to fail, the contents of the failing DIMM is copied to the spare DIMM
in that channel. When all of the data is copied, the primary DIMM is automatically removed from
service. Since one DIMM per channel is always maintained as a spare, a maximum of only 75%
of the installed memory is usable. Memory online sparing is configured in the BIOS.
Installing PCI expansion cards
Use the following chart to determine the PCI slot into which you should install your expansion
card.
Caution
This server does not have PCI hot-plug capability. Do not attempt to install or remove
a PCI card without turning off your server and disconnecting it from the AC power source.
