Instructions for applying power to the enclosure.

CAUTION:
Do not operate the enclosure system until the ambient temperature is within the specified operating range. If the drives were recently installed, make sure that they have time to adjust to the environmental conditions.
  1. Connect the power cables to the PSUs.
  2. Move all PSU power switches to the on position, as shown in the following figure.

  3. The system power LED on the ops panel is lit green and the disk drive motors start.
Important: If main power is lost for any reason, the system restarts automatically when power is restored.
Note: For more information about the ops panel LEDs and related fault conditions, see Ops panel LEDs.

Consider the following points when turning PSUs on or off:

  • Remove the AC cord before inserting or removing a PSU.
  • Turn off the PSU switch before inserting or removing the AC cord.
  • Allow 15 seconds between turning the PSU off and back on again.
  • Allow 15 seconds between turning one PSU in the system on and the other PSU off.
  • Never turn off a PSU while any amber LED is lit on the partner PSU.
  • The enclosure must be left in a powered state for 30 seconds following resumption from standby before the enclosure can be placed into standby again.
