53WHHbk1.book Page 2 Tuesday, March 14, 2000 5:47 PM If your array has a standby power supply (SPS), use the SPS circuit breakers to turn off the DPE (see Figure 1-1). If your array does not have an SPS, use the AC distribution strips for a rackmount DPE or the power distribution unit (PDU) switches for a deskside DPE to turn off power. NOTE: In a rackmount DPE, the power in the distribution strips may be controlled by a circuit breaker located inside the cabinet (if the cabinet has such breakers) or a circuit breaker located externally to the cabinet. When you turn off power to an array with an SPS, the On Battery light may come on for a maximum of 90 seconds while the DPE continues to run. This is a normal condition. Wait for the On battery light to go off and the fans to stop before continuing service to the array. To turn on power, reverse the procedure. 1-2 Dell PowerVault 65xF Storage System Information Update
