Replacing the redundant power supply
The redundant power supply offers fault tolerance and hot-swap capabilities.
However, if the power distribution board at the base of the power supply or
some other shared component fails, the entire power supply and its housing
must be replaced. A failure of a shared component is indicated by both power
supply status LEDs flashing and an audible alarm, or the system will fail to
power up.
To replace the redundant power supply:
1
Turn off the system and disconnect the power cord and all peripherals.
2
Open the case. (See “Opening the case” on page 23 and “Preventing static
electricity discharge” on page 22.)
3
Disconnect the power supply connectors from all internal devices,
including the 3.5-inch diskette drive, the CD drive, and all hard drives.
4
Disconnect the main and auxiliary power supply signal connectors from
the system board, by pressing on the tab to release the connector, then
gently pull the connector from the board.
