Enclosure Power Supply Status LEDs
Each power supply installed in an Octane III enclosure has a bi-color (green/amber) status LED,
see Figure 2-1 for an example. These LEDs can be viewed by looking carefully through the
upper-rear perforated sheetmetal on the enclosure to determine if a problem with the supply exists.
If the supply indicates a malfunction (yellow LED), it should be replaced immediately.
Figure 2-1 System Power Supply Status LED
The LEDs will either light green or amber (yellow), or flash green or yellow to indicate the status
of the individual supply. See Table 2-2 for a complete list.
The Fault LED of a populated PCI slot is
illuminated (on).
If the fault LED remains on, consult the SGI Octane III
Deskside Workstation Component Replacement
Guide
and re-seat or replace the PCI card.
The fault LED of a hard disk drive is on. Consult the
SGI Octane III Deskside Workstation
Component Replacement Guide
to replace the drive.
