Instruction manual

An SCSI interface card has the following lights:
TERM POWER light 1

light is off and the TERM POWER light is on, there is an active single-ended
(SE) SCSI connection.

The ACTIVE light, which is green, is lit when the using system is
communicating with the SCSI Enclosure Services (SES) processor or the disk
drives.
RESET light 4
The RESET light, which is green, comes on when a Power On Reset (POR) or
a SCSI Bus Reset occurs. This light is switched off by the SES processor.
FAULT light 5
The FAULT light, which is amber, comes on if the SCSI interface card fails.
