Chapter 1 Product Description
RAID drive indicators
On a K2 Media Client with a SCSI backplane, each RAID drive has LEDs that
indicate status. You must remove the fan module to see these LEDs. The following
table explains the status conditions indicated by the different LED behaviors. If two
or more status conditions occur simultaneously, the LED displays the behavior for the
highest priority condition.
On a K2 Media Client without a SCSI backplane, refer to “Using the Adaptec Storage
Manager to identify a failed drive” on page 54 .
Rear panel indicators
The following indicators are visible from the rear panel view.
Solid Red Global failure — The K2 Media Client system
software has detected a critical error or failure that
impacts record/play operations. 2
Solid Yellow Warning — The K2 Media Client system software has
detected a problem that requires attention but does not
immediately impact record/play operations. For
example, a fan or power supply has failed but its
redundant partner is maintaining functionality. 3
Flashing Yellow pattern three time
a second. Drive failure — An internal RAID drive has failed. If
RAID 1, the failure does not immediately impact
record/play operations. The redundant partner RAID
drive is maintaining functionality. 4

Yellow/Green once a second. Drive rebuild — If RAID 1, an internal RAID drive is
rebuilding. 5

operating normally. 5
