Additional power information

This topic provides additional power information.

The TS7650G supports simultaneous power on to the system components. Always follow the power on sequence in Power procedures for ProtecTIER version 3.2 or 3.3 during any attended power on procedure.

In an optimal state, the disk controllers and disk expansion modules should recover automatically from an unexpected shutdown and unattended simultaneous restoration of power to system components. After power is restored, call IBM support if any of the following conditions occur:

  • The disk component logical drives and arrays are not displayed in Storage Manager.
  • The disk component logical drives and arrays do not come online.
  • The disk component logical drives and arrays seem to be degraded.
Note: Always wait at least 30 seconds between the time that you turn off a power switch and the time that you turn on the power again.
