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 fi ve 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.
