Memory Upgrading
The system memory can be expanded by adding one or more memory banks to the existing
configuration. This operation may also require the replacement of the memory risers, in
case the single-bank memory risers (FRE risers) are installed.
Warning: Before handling any memory bank, be sure you know the configuration rules
described in Memory Configuration , on page 5-1.
Adding a Memory Bank on Memory Risers
1. Perform a system power off and unplug the unit power cord from the wall outlet (for
details, if needed, see Preliminary Operations , on page 6-3).
2. Remove the left lateral panel (for details, if needed, see Lateral Panel Removal , on
page 6-7).
3. Wear the antistatic wrist strap. It is recommended not to touch the finger connector (for
details, if needed, see How to Handle Hardware Components , on page 6-2).
1st step: Memory risers removal
1. Check the LED’s of the risers and wait until they are off. Notice that this could take
several minutes.
2. Using the hooked clips of the memory riser, unplug one memory riser and slide it out of
the metallic structure.
3. Lay it down on an antistatic envelope until all operations on it are concluded.
4. Repeat the steps for each of the 4 memory risers.
If you need to replace the memory risers, remove the memory present on the old risers,
following the instructions below; if this is not the case, skip to the
Installation of memory

step, on page 6-11. You may also need to execute this
