Link Status Lights on the Adapter

Link Status Lights on the Adapter

If a fault occurs that prevents the operation of a particular link, the link status lights of the various parts of the complete link show that the error has occurred.

You can find the failing link by looking for the flashing green status light at each end of the affected link. Some configurations might have other indicators along the link (for example, SSA connector cards) to help with FRU isolation.

The meanings of the disk drive and adapter lights are summarized here.

Status of Light	Meaning

Off	Both SSA links are inactive.

Permanently on	Both SSA links are active.

Slow flash	Only one SSA link is active.
(2sec.-on, 2sec. off)

If you need more information about the lights, see:

For adapter lights,'Introducing the SSA RAID Cluster Adapter for PC Servers, SSA and RAID'
For other lights, the service information for the device that contains the lights.
