Upgrades and Options
Memory Board
The following sections provide procedures for
upgrading and configuring the memory board in your
system. Topics covered include:
■
Removing the Memory board
■
Adding or removing DIMMs
■
Installing the Memory board.
Notice: Electrostatic discharge (ESD) can damage add-
in boards and other components; place them on an
antistatic surface. Modify the memory board only at an
ESD workstation. Otherwise, wear an antistatic wrist
strap attached to chassis ground.
Removing the Memory Board
Warning: If the system has been running, any
processor and heat sink already installed on the board
will be hot. To avoid the possibility of a burn while
removing the processor/memory board, let the
components cool for 10 minutes before continuing with
the procedures described here.
1. Power off the system and remove the top cover as
described earlier in this chapter.
Notice: Observe static precautions. Use an antistatic
wrist strap.
2. Remove the memory board support panel described
earlier in this chapter, see Removing a Board
Support Panel.
3. Holding the board by its edges, carefully pull it out
until the edge connectors are free (see Figure 5-4).
4. Store board in an antistatic protective wrapper if
you are not installing or removing a DIMM at this
time.
