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 from each supply, pressing the lever 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).
