Caution -
LED at the front of the system unit should not be lit and the fan should not be
running. When the system power switch is in the Standby position, and the AC
power cord remains connected to a power outlet, hazardous AC voltage is still
present in the power supply primary. Do not attempt to service the power supply
under these conditions. Disconnect the AC power cord prior to handling the power
supply. When servicing any other system component, the AC power cord should
remain connected and poses no safety hazard.
2. Locate the VSIMM slot on the main logic board.
See Figure 11–5.

Grasp the VSIMM at its top corners and carefully wiggle it free from its connector
(see Figure 11–6). Be careful not to touch any of the components on the VSIMM.
5. Place the VSIMM on the antistatic mat.
