Powering off

Complete this task to turn off the power to a server enclosure and all attached expansion enclosures.

Perform these steps to turn off the power to a storage unit:

Ensure that all I/O operations are stopped.
Quiesce all hardware resources in the server enclosure.
Press and hold the power button that is located on the left side of the rear operator panel on the server enclosure for five seconds. The unit completes the power-off sequence to turn off the server enclosure and each of the attached expansion enclosures. The server enclosure controls the power-off sequence for the entire storage unit, including all of the expansion enclosures. Each expansion enclosure turns off the enclosed resources in the necessary order. A delay of several minutes can occur before the system fully turns off all of the enclosures, depending on how many attached expansion enclosures are connected.

The enclosure is completely powered off after the fans have stopped spinning, the dc LED indicator on the power supply is flashing, and the ac LED indicator on the power supply is a solid green light. The power-on LED indicators on both the rear operator panel and the front display panel flash intermittently after the enclosure is fully turned off.

CAUTION:

Do not remove the ac power cords from any enclosure while any of the fans are still spinning. You must wait until the complete power off sequence has finished before you remove the power cords. Failure to follow the correct power off procedure may cause loss of access to your data or the inability to successfully restart the DS6000™.
