Power down the enclosure: a. Power down any attached servers. See the server documentation. b. Press the Power On/Standby button on the enclosure. c. Wait for the system power LED to go from green to amber. d. Disconnect the power cords. 2. Extend or remove the enclosure from the rack in which it may be installed: a. Loosen the front panel thumbscrews that secure the enclosure faceplate to the front of the rack. Removal and replacement procedures 52

Verifying component failure
Use the following methods to verify component failure:
Check the hard drive status LEDs as identified in the following table. Check with known good hard
drives.
Check the host log for errors.
Hard drive LED combinations
Online/activity LED
(green)
Fault/UID LED
(amber/blue)
Interpretation
On, off, or flashing Alternating amber
and blue
The drive has failed, or a predictive failure alert has been
received for this drive; it also has been selected by a
management application.
On, off, or flashing Steadily blue
The drive is operating normally, and it has been selected by a
management application.
On
Amber, flashing
regularly (1 Hz)
A predictive failure alert has been received for this drive.
Replace the drive as soon as possible.
On
Off
The drive is online, but it is not currently active.
Flashing regularly
(1 Hz)
Amber, flashing
regularly (1 Hz)
Do not remove the drive. Removing a drive may terminate the
current operation and cause data loss.
The drive is part of an array that is undergoing capacity
expansion or a stripe size migration, but a predictive failure alert
has been received for this drive. To minimize the risk of data
loss, do not replace the drive until the expansion or migration is
complete.
Flashing regularly
(1 Hz)
Off
Do not remove the drive. Removing a drive may terminate the
current operation and cause data loss.
The drive is rebuilding, or it is part of an array that is undergoing
capacity expansion or a stripe size migration.
Flashing irregularly Amber, flashing
regularly (1 Hz)
The drive is active, but a predictive failure alert has been
received for this drive. Replace the drive as soon as possible.
Flashing irregularly Off
The drive is active and it is operating normally.
Off
Steadily amber
A critical fault condition has been identified for this drive and the
controller has placed it offline. Replace the drive as soon as
possible.
