Verifying SAS hard drive operation
Each SAS disk drive has an activity LED indicator on the front of the drive.
NOTE:
On the server, only the activity LED is used. The status LED is not monitored by the OS.
Verify that the LED shows the correct activity indication for all disk drives that you installed:
Procedure
1. Turn on power to the server and display monitor.
2. During the boot sequence, watch the activity LED on each SAS disk drive.
3. The LED quickly cycles from amber to green. The LED stays steady green until the drive spins up.
4. If the activity LED stays illuminated steady green on any SAS disk drives (after the drive spins up), the
drive might not be seated correctly. Check installation as follows:
a. Turn off the server power button and unplug the AC power cords and any cables.
b. Re-seat all of the SAS disk drives installed in the server.
c. Reconnect the AC power cords and any cables. Restart the server to determine whether the LEDs
now become illuminated during the boot. If not, contact your reseller.
System LAN LEDs
Four system LANs are located on the rear bulkhead of the server. These LANs are connected to the
system board.
