Installing a DAE2P/DAE3P 4. Repeat steps 1 through 3 for each disk enclosure in the cabinet, as necessary. 5. Set any SPS switches, and then the master (or main circuit breaker) switches, to the on position. The disk enclosures in the cabinet power up. The only power switches that control DAE2Ps and DAE3Ps are those on the SPS and the cabinet master switch or circuit breakers, which are normally on. As a result, a DAE2P/DAE3P is always active. When you initially apply AC power to a disk enclosure, the disk drive modules power up according to their specifications, and spin up in a staggered sequence. The slot spin-up delays range from 0 to 84 seconds. (The same delays are used when you insert a drive module while the system is powered up.) Connecting AC Power 2-9
