6.3.2 LED Support

The backplanes support an activity/fault LED for each of the hard drive connectors. The LED

illuminates green for activity or amber for a drive fault.

The green activity LED is driven by the

SAS/SATA hard disk drive directly.

The amber fault LED is driven by the VSC410 management

controller whenever a fault condition is detected.

When the drive is used in a RAID configuration,

the RAID controller has control over the fault LED and it may exhibit

different behavior.

The activity LED functionality is controlled directly by the hard drives.

This causes the LED to

function differently between SAS and SATA drives.

The expected operation is outlined in the

following table.

6.3.3 Backplane Connector Definitions

The backplanes include several different connectors. This section defines the purpose and pin-

out associated with each.

6.3.3.1 Power Connector (Backplane to Power Supply Harness)

The backplane provides power to the three hard drive bays and the slimline drive bay. An 8-pin

power cable is routed from the power supply and plugs into a 2x4 shrouded plastic PC power

connector on the backplane.

The following table shows the power connector pin-out:
