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. Remove the front bezel assembly. See “Removing the blade-server front bezel
assembly” on page 23 for details.
5. Locate the DIMM slots in which you want to insert the system memory modules.
See Table 1 on page 28 and Figure 16 on page 28 for guidance.
6. Remove any modules that are to be replaced or that have become redundant.
a. Open the retaining clips on either end of the DIMM slot. This lifts the DIMM
and disengages it from the slot.
b. Pull the DIMM out of the slot.
7. Insert the new DIMMs.
a. Ensure that the retaining clips at both ends of the DIMM slot are in the open
position.
b. Place the DIMM in the slot, contact side down. Check the orientation of the
module. The locating pin in the slot must match the corresponding cut-out
on the module.
c. Carefully press the module into place until the retaining clips snap into
position. Make sure that the clips are locked properly.
Note: Unused system memory slots do not require DIMM fillers.
If you have other options to install, do so now. Otherwise, go to “Finishing the
installation” on page 35.
Adding or changing I/O buffer DDR2 memory modules
This section describes how to add I/O buffer memory. For instructions on how to
add system memory see “Adding or changing system memory” on page 27.
Each IBM PowerXCell 8i companion chip has one DIMM slot for I/O buffer memory.
The QS22 blade server supports VLP DDR2 1 GB DIMMs. You must add memory
as a pair of DIMMs, one for each IBM PowerXCell 8i companion chip.
