1.3.1 Powering On the Disk Array System

1.3.1.1 AC Operating Mode
The disk array unit has a mechanism that powers the unit itself on automatically, not through operation
of the power switch, according to power supply to AC.
AC operating mode is enabled in the factory default settings. AC operating mode can be disabled by
issuing a certain command to the disk array unit. When AC operating mode is disabled, you need to
use the power switch to control the power of the disk array unit.
For information on how to change the factory default settings to disable AC operating mode, see NEC
Storage Software Configuration Setting Tool User's Manual (GUI) for the M Series.
Release 6.0
When AC operating mode is disabled, the power control function through
ESMPRO/AC is not available because the control circuits on the controllers
are not powered on. Make sure to enable AC operating mode when you use
the power control function through the ESMPRO/AC.
