Chassis Power Supply Replacement

Warning:

Only personnel with extensive experience repairing server hardware should

attempt to replace or upgrade components inside an SGI Octane III deskside workstation

enclosure.

The Octane III deskside workstation uses two AC-to-DC power supplies. Each power supply has

a separate power cord and is rated for a maximum DC output of 1000 watts at 100-120 VAC, or

1200 watts at 200-240 VAC. Each power supply is cooled by a built-in 40-mm fan. Each supply

has one (bi-color) status LED on the rear which may be visible through the perforated sheetmetal

panel at the upper rear of the enclosure.

Note: You must turn off the power for the enclosure and then unplug the AC power cords from

power outlet and/or the rear of the system to completely remove power from the system before

removing/installing a power supply.

If a power supply unit (or its cooling fan) fails, the system must be shut down. The system requires

both power supplies to operate.

If you need to replace the power supply unit and the system is out of warranty, replacement units

can be ordered directly from your SGI sales or service representative.
