SCSI LEDs (DA1/DA2)
There are two SCSI LED indicators
on the serverboard. DA1 indi-
cates activity on SCSI Channel A
and DA2 indicates activity on SCSI
Channel B.
Unit Identifier
A Unit Identifier (UID) feature on
the server makes it easy to locate
the unit in a large stack. While
servicing the system, if you find
you need to work on the other
side of the unit, push the UID but-
ton (located on the far left of the
control panel on the front and to
the right of the VGA port on the
rear of the chassis) to illuminate
an LED on the other side of the
chassis. When you walk around
to the other side of the rack, the
unit will then be easy to spot. The
LED will remain on until the UID
button is pushed again. The rear
chassis UID is a button and LED in
one. The front control panel in-
cludes a separate LED and button.
