The power UID is located on the front of the disk enclosure.
Verifying component failure
Check for improper or failed operation of the heartbeat and fault LEDs
on the front right bezel, and also the System UID LEDs. Improper LED
behavior may be an indication that the interconnect board needs to be
replaced. The following table describes LED behavior.
•= Health. Solid green indicates the enclosure is operating
normally. Blinking green indicates that the enclosure is starting up
and not ready, performing POST. Off indicates that there is no power.
•= Fault warning. Flashing amber indicates a fault of lesser im-
portance, while solid amber indicates a fault of greater importance.
•= Unit identification. Push button to illuminate solid blue; push
again to turn off. The UID mimics the status of the UID at the front of
the enclosure. A remote session from the management utility can also
illuminate this LED.
Removing the power UID interconnect
board
1. Schedule a maintenance window.
2. Stop all I/O to the enclosure.
3. Power down the enclosure by pressing and holding the On/Standby
button on the rear of disk enclosure, until the system power LED
changes from green to amber.
4. Remove all cabling from the rear of the enclosure. Ensure all cabling
is marked to facilitate re-cabling later.
WARNING!
A disk enclosure fully populated is heavy. Prior to
removing the enclosure from the rack, remove each
disk and label it with its bay number. Place each disk
on a clean surface. If this is not possible, two people
are required to remove the enclosure from the rack to
prevent injury.
5. Remove hard drives from the enclosure.
Press the release button on the drive lever (1), and rotate the lever
to the left (2).
Then, pull and remove the disk drive out of the drive bays (3).
6. Loosen the thumbscrews that secure the enclosure to the front of the
rack, and remove the enclosure from the rack.
7. Remove the top access cover.
a. Lift the access panel latch (1). The access panel will slightly
disengage from the enclosure.
b. Slide the access panel to the rear (2) and lift away from the
chassis.
NOTE:
A Torx tool with T-10 and T-15 ends is provided inside
the enclosure chassis, on top of the I/O module
housing.

8. Separate the drive cage from the chassis.
a. Disconnect all cables from the backplane.
b. On each side of the chassis, remove the three T-10 screws that
secure the drive cage to the chassis.
c. Grasp the top of the drive cage, slide it off the guideposts on
the bottom of the chassis, and lift the drive cage just out of the
chassis.
9. Remove the front UID.
a. Remove the T-10 screw securing the bezel to the chassis ear
and let the black bezel separate from the ear.
b. Remove the T-10 screw securing the interconnect board to the
bezel and lift the interconnect board away from the bezel.
c. Remove the piece of tape securing the cable to the drive cage.
d. Disconnect the cable from the interconnect board.
Installing the power UID interconnect
board
1. Secure the power UID interconnect board.
a. Connect the replacement cable to the replacement interconnect
board.
b. Secure the interconnect board to the bezel with the T-10 screw.
c. Secure the cable to the drive cage with the provided strip of
tape.
d. Secure the bezel to the chassis ear with a T-10 screw.

2. Secure the drive cage to the chassis.
a. Slide the drive cage in position, aligning the keyhole openings
on the bottom flange of the drive cage with the guideposts on
the bottom of he chassis, and replace the six T-10 screws.
b. Reconnect all cables to the backplane.
NOTE:
The cables are keyed and are different in size, to
prevent connecting to the wrong port.
3. Replace the top access cover.
4. Reinstall the enclosure in the rack, making sure to tighten the front
bezel thumbscrews.
5. Reinstall the enclosure in the rack.
WARNING!
Reinstall the drives in the same slot locations.
With the drive lever in the open position, reinsert drives fully into
each bay, pressing on the lever to secure each drive, remove any
labels added to mark the drives.
6. Reattach the power and data cables to the enclosure components.
7. Press the On/Standby button on the power UID bezel (located at
rear of enclosure) and hold it down long enough to power up the
enclosure.
8. Restart all servers with access to the disk enclosure, to ensure that
the storage is discovered properly.
Verifying proper operation
After replacing the interconnect board, check the heartbeat, fault, and
UID LEDs on the front UID for proper operation.
NOTE:
Wait one minute after powering up the enclosure for the system
to check component status.
Returning the failed component
Follow instructions shipped with the replacement part.
