Connecting AC Power
2-9
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.)
