Removing and Replacing Power Supplies
007-4701-003 103
Removing and Replacing Power Supplies
Each module in a Silicon Graphics Prism system can contain one or two sled-mounted
power supplies (see Figure 4-20). For information on determining the operational status
of a power supply, see “Reading Power Supply Status LEDs” on page 129.
Note: The XG2N graphics module always requires two power supplies; no redundant
power is available. The system must be shut down prior to power supply replacement.
Figure 4-20 Power Supplies Location
To replace a power supply, follow these steps:
1. If you are replacing a power supply in an XG2N module, power off the Silicon
Graphics Prism platform as described in the section “Powering Off Manually” on
page 25. The XG2N module always uses two supplies. There is no redundant power
supply option available.
2. Remove the power supply to be replaced, as follows:
a. Swing open the bezel door located on the right side of the module front panel.
With a Phillips screw driver, unscrew the two screws on the screen cover as
shown in Figure 4-21A.
