The following notes supplement information in the SPARCstorage UniPack
Installation card.
When power is applied to the enclosure, a green status LED (located on the
front of the unit in the lower right corner) is lit.
If your enclosure has a hard disk, the LED blinks to show small computer
system interface (SCSI) bus activity.
Note – With heavy activity, the LED on hard disk units can be off for up to ten
seconds.
The enclosure is self-terminating. Termination is indicated by two LEDs
located on the back of the unit in the lower right-hand corner:
•
Hi LED: Indicates that the high order SCSI bits are terminated
•
Lo LED: Indicates that the low order SCSI bits are terminated
The Hi LED will be lit if the enclosure is followed by a narrow SCSI device or
if the enclosure is the last device in a SCSI chain.
The Lo LED will be lit only if the enclosure is the last device in a SCSI chain.
These LEDs are for set-up and troubleshooting only and should be ignored
during normal operation.
Most of the SPARCstorage UniPack drives do not require operating system
patches. If your have any problems using your drive, refer to the Product Notes
that may accompany this documentation.
