To install I/O buffer memory, complete the following steps:
1. Read the safety information beginning on page vii and “Installation guidelines”
on page 19.
2. If applicable, shut down the operating system, turn off the blade server, and
remove the blade server from the BladeCenter unit. See “Removing the blade
server from the BladeCenter unit” on page 20.
3. Open the blade server cover. See “Opening and removing the blade server
cover” on page 21.
4. Locate the DIMM slots for the I/O buffer DDR2 memory modules.
There are two DIMM slots, one for each IBM PowerXCell 8i companion chip.
The slots are labelled
IOBUF 1
and
IOBUF 2
. You must install a 1 GB DIMM for
both IBM PowerXCell 8i companion chips.
5. Remove the DIMM fillers from the slots. Retain the DIMM fillers. They are an
important part of the blade server cooling system and you need them if you ever
remove the I/O buffer DIMMs from the blade server.
6. Place each DIMM in its slot, contact side down. Check the orientation of the
modules. The locating pin in each slot must match the corresponding cut-out on
the module.
7. Carefully press the modules into place until the retaining clips snap into place.
Make sure that the clips are locked properly.
If you have other options to install, do so now. Otherwise, go to “Finishing the
installation” on page 35.
