Unit Identifi er
A Unit Identifi er (UID) feature on the
server makes it easy to locate the unit
in a large stack. While servicing the
system, if you fi nd you need to work
on the other side of the unit, push the
UID button (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 at JPB1 is a button and
LED in one. The front control panel
includes a separate LED and button.

LE1 LED
When illuminated, the LE1 LED indi-

the power supply before removing any

sors or memory (not necessary for
SCSI or SATA drives).
