Power Supply Status
The Power Supply Status LED indicates the condition of the power supplies. The
LED will illuminate steady green when all the power supplies are functioning
normally and will change to amber if one of the power supplies should fail. The
LED will also switch to amber if the power system is in a non-redundant state. A
failed component can be identified via the Operator Control Panel and the lack of
an illuminated “DC Good” LED located on each power supply unit.
Fan Status
The Fan Status LED indicates the condition of the cooling fans by changes in its
color. The LED will illuminate green when all of the fans are functioning normally
and will change to amber if any of the fans fail.
When a failed component is present, use the Operator Control Panel to identify
the failed fan. The fans are identified on the rear door panel via placarded
markings. For more information see Hardware Menu on page 42.
Status LEDs
There are eight Status LEDs located in windows on the front panel (for the
rack-mount system they are the lower set of LEDs and for the tower-based system
they will be the set on the left hand side).
These LEDs, in conjunction with an approved RAID controller, will indicate the
status of a specific disk drive by their state (flashing or steady) and/or color
(amber or green).
For more information on interpreting these indications, see LED Descriptions on
page 39.
Activity LEDs
There are eight Activity LEDs located in windows on the front panel (for the
rack-mount system they are the upper set of LEDs and for the tower-based system
they will be the set on the right hand side). These LEDs will flash indicating a
specific drive is being accessed, either as reads or writes.
