About this task
The DC power supply for the IBM c-type SAN Device is 3000 W.
Note: Hazardous voltage or energy is present on the backplane when the system is

operating. Use caution when servicing.

To install a DC power supply in the IBM c-type SAN Device, follow these steps:

them as follows:
a. Unscrew the three screws on top of the terminal box located in front of the
power supply, and remove the safety cover.
b. Unscrew two nuts from each of the four terminal slots in the terminal box.
c. In each of two negative slots (labeled as -), place the lug on the end of a
negative power cable, and fasten with two nuts.
d. Tighten the nuts to 40 in-lb (4.5 N-m). In each of two positive slots (labeled
as +), place the lug on the end of a positive power cable, and fasten with
two nuts.
e. Tighten the nuts to 40 in-lb (4.5 N-m).
f. Place the safety cover on the terminal box and fasten with three screws.

supplies are from separate power feeds or buses than the other half for
redundancy from the loss of a feed or bus.

CAUTION:

In a system with dual power supplies, connect each power supply to a
separate source. In case of a line failure, the second source will most likely
still be available.
