Installing the riser board To install the riser board, reverse the removal procedure: 1. Attach the board to the chassis, securing it with the thumbscrew. 2. Install the access panel. 3. Insert the enclosure into the rack and power up the enclosure. Verifying component replacement After replacing the riser board, be sure there is power to the 7-segment display board. Midplane 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. • 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 MSA70 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 host log for errors. • Check the following component status LEDs as identified in the following tables: • Hard drives-test with known good hard drives. • I/O module-test with known good I/O module. • Fan module-test with known good fan module.

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.
•
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 MSA70 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 host log for errors.
•
Check the following component status LEDs as identified in the following tables:
•
Hard drives—test with known good hard drives.
•
I/O module—test with known good I/O module.
•
Fan module—test with known good fan module.
