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). Consult the
SGI Octane III Cluster Server Component
Replacement Guide
and reseat the PCI card. If the fault
LED remains on, replace the PCI card.
The fault LED of a hard disk drive is on. Consult the
SGI Octane III Cluster Server Component
Replacement Guide
and replace the disk drive.
