12. Tilt the midplane up and remove it from the chassis (2). Installing the midplane To install the midplane, reverse the removal procedure: 1. Insert the midplane into the chassis, making sure that it is engaged with the backplane. Then press the lever down to secure it in the chassis and connect the cables. 2. Install the 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 midplane, check the following to verify the component is operating normally: • Hard drive status LEDs • I/O module status LED • Fan module status LED Backplane 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. Removal and replacement procedures 51
