Removing power from the MSA CAUTION: System power to the MSA does not shut off completely with the power switch. The two positions of the front panel power switch should be considered as On and Standby, rather than On and Off. The standby position removes power from most of the electronics and the hard drives, but portions of the power supply and some internal circuitry remain active. • To remove all power from the system, you must disconnect the power cord from the storage system. • In systems with multiple power supplies, you must disconnect all the power cords to remove power completely from the system. To remove power from the MSA, do the following: 1. Ensure that a known good backup is available. 2. Schedule a maintenance window. 3. From the servers in the network, stop all access to the MSA. 4. Press and hold down the MSA Power On/Standby button for five seconds to place the MSA in Standby mode. NOTE: Placing the MSA in standby mode disables the main power supply output, but still provides auxiliary power (+5V) to the device. 5. Verify that the Power On/Standby button LED is amber/off and that the fans are off. 6. Disconnect all power cords from the AC outlets, and then from the device. 7. Disconnect all external peripheral devices from the MSA. 72 Customer replaceable components
