Replacing the VSIMM

Caution – Verify that the system power switch is in the Standby position. The green
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.
Caution – The SIMMs installed in your system must be specifically designed to
operate in it. Do not transfer a SIMM from a different Sun system unless you are sure
it is compatible with your system.
