Verifying component replacement After replacing the fan, check the fan status LED. I/O module 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 I/O status LED: Green = System activity Amber = Fault condition Off = No system activity • Check the host log for errors. Removing the I/O module 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. 2. Disconnect any SAS cables connected to the I/O module. Removal and replacement procedures 33
