Note: If the system power cord is connected to a power
control unit such as an UPS (Uninterruptible Power S upply),
refer to the UPS user's guide for proper power-off
procedures.
7. Remove the left-hand side access panel of the system chassis following
procedures previously described in this chapter.
!
CAUTION
For proper cooling and airflow, do not operate the system
with the side access panel removed. Always replace the
panel before powering on the system.
8. Remove the processor air duct. See Processor Air Duct Removal earlier in
this chapter.

Figure 4-15).
10. Gently push the plastic ejector levers out and down to eject a DIMM from its
socket. See Figure 4-18.

or gold edge connectors. Carefully lift it away from the socket, and store it
in an antistatic package.
