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.
