About this document
Enclosure
This document details procedures for replacing a failed 7-
segment display board in an MSA6X/7X Series Enclosure.
7-segment display board
Before you begin
replacement instructions
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.
For updates, visit the HP website:
http://www.hp.com/support/manuals.
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
Use the following methods to verify component failure:
•
Check the 7-segment display board LED display for
activity. If the LED display is not illuminated, the
component may have failed.
NOTE: No power to the 7-segment display board can also be
an indication of the failure of the riser board, the power
supply, or the midplane.
•
Check the host log for errors.
