2.4.2 Connecting AC Power and ECB Cables
If power is applied to the master cabinet, power down the controllers by following the
procedure contained in the DIGITAL StorageWorks HSZ80 Array Controller HSOF
Version 7.0 Service Manual. Remove ac power to the BA370 by moving the switch on the
ac power entry controllers to 0. Remove ac power to the Power Distribution Unit (PDU)
by moving the breaker switch to 0. Disconnect the power distribution unit from the ac
power source.
1. For BA370’s with 4+4 power configurations, go to the rear of the cabinet and plug
the black ac power cord from the BA370’s ac power entry controller into the bottom
PDU that already has a black power cord plugged into it. For dual-redundancy units,
plug the gray ac power cord from the BA370’s ac power entry controller into the top
PDU in the rear of the SW600 cabinet. Attach ECB cables to the ECB and to the
cache modules The top BA370 ECB is located on the left-hand side of the ECB
shelf. The bottom BA370 ECB is located on the right-hand side of the ECB shelf.
Repeat the same procedure for the 41U RETMA cabinet (note: the PDUs are located
in the front and rear of the cabinet in the 41U).
2. Plug the PDU ac power cable(s) into the ac power source.
3. Connect the ECB Y-cables between the ECB batteries and the cache modules as
shown in Figure 2–15.
