About this document
This document details procedures for replacing a failed
backplane in an MSA6X Series Enclosure or ProLiant DL320S.
Before you begin
CAUTION: Before removing the failed component, make sure
that you have the replacement part available. Removing a
component impacts the airflow and cooling ability of the
device.
To prevent improper cooling and thermal damage, do not
operate the enclosure unless all bays are populated with either
a component or a blank.
Do not remove more than one component or blank from the
enclosure at a time. Doing so impacts the airflow and cooling
ability of the device. To avoid possible overheating, insert the
new or replacement component as quickly as possible. If the
internal temperature exceeds acceptable limits, the enclosure
may overheat and automatically shut down or restart.
Parts can be damaged by electrostatic discharge. Use proper
anti-static protection.
Verifying component failure
Before replacing the backplane, 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.

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.
Off Amber, flashing
regularly (1 Hz)
A predictive failure
alert has been received
for this drive. Replace
the drive as soon as
possible.
Off Off The drive is offline, a
spare, or not
configured as part of
an array.
Removing the backplane
To remove the backplane:
1. 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.
CAUTION: Be sure that the server is the first unit to be
powered down and the last to be powered back up.
Taking this precaution ensures that the system does not
erroneously mark the drives as failed when the server is
powered up.
2. Remove the power supplies by disconnecting the power
cord on each supply, pressing the latch inward (1), and
sliding the component out of the chassis (2).
3. Remove the system fans by pressing up on the lever on
each fan (1) and sliding the fan out of the chassis (2).
4. Remove the I/O module by squeezing the lever (1) and
rotating down (2), and then sliding the I/O module out of
the chassis (3).

5. Remove the I/O module blank as you did the I/O module.
6. 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.
b. Disconnect the cabling and extend or remove the
enclosure from the rack.
7. Remove the access panel:
a. Lift the access panel latch (1).
b. Slide the access panel to the rear (2).
8. Remove the 7-segment display board:
a. Pull the pin out to release the board (1).
b. Put your finger inside the slot to slide the board out of
the chassis (2).
9. Remove the riser board by loosening the thumbscrew (1)
and lifting the board out of the chassis (2).
10. Disconnect the cables (1 and 2) from the midplane.
11. Loosen the two captive thumbscrews from the midplane
(1).
12. Push the board toward the back of the unit to disengage it
from the backplane (2).
13. Tilt the midplane up and remove it from the chassis (3).
14. Remove the screw from the backplane (1).
15. Tilt the backplane up from the bottom and lift it out of the
chassis (2).

Installing the backplane
To install the backplane, reverse the removal procedure:
1. Insert the backplane into the chassis, securing it with the
screw.
2. Install the midplane, riser board, 7-segment display board,
I/O module and blank, fans, and power supplies.
3. Install the access panel.
4. Insert the enclosure into the rack and power up the
enclosure.
Verifying component replacement
After replacing the backplane, check the hard drive status LEDs.
