When the storage system power cables are plugged into the PDUs and the PDU breakers are on, the storage system is in idle (basic supply only) mode. When the storage system is in idle mode:

  • The amber Basic Supply (BS) LED on the control panel is on. AC power is applied to the power supplies.
  • The green READY LED is off. The controller chassis and drive boxes are not operational.
  • The fans in both the controller chassis and drive boxes are running.
  • The cache backup batteries are being charged.
  • The storage system consumes significantly less power than it does in operating mode. For example, a storage system that draws 100 amps while operating draws only 40 to 60 amps in idle mode, depending on the number of drives in the system. The more drives, the more power is saved. See Table 1 and Mechanical environmental specifications.

To put the storage system into idle mode from the OFF condition:

  1. Ensure power is available to the AC input boxes and PDUs in all racks.
  2. Turn on all PDU power switches and circuit breakers.

To put the storage system into idle mode from a power on condition, perform the steps in Power off procedures.

To shut down the storage system, perform the power off procedures, and then turn off all PDU circuit breakers.

Warning: Verify the storage system is turned off normally and in idle mode before turning off the PDU circuit breakers. Otherwise, turning off the PDU circuit breakers can leave the storage system in an abnormal condition.
