3.1.2.3 Turning Off Power for a Planned Shutdown
Storage array modules are designed to run continuously, 24 hours a day. After you
power up a module, it should remain on unless you need to perform an upgrade or
service procedure that requires powering down.
Use the following procedure to turn on power to one or more modules in a storage
array for a planned shutdown. Figure 3-11 on page 3-10 shows the location of the
power supply switches.
