PDMs
There are eight PDMs mounted in the rear of each rack:
Four mounted on the left vertical rail connect to PDU 1.
Four mounted on the right vertical rail connected to PDU 2.
Each PDM has six AC receptacles and two thermal circuit breakers. See
Figure 58. The PDMs distribute the AC power from the PDUs to the enclosures.
Two power sources exist for each controller pair and drive enclosure. If a PDU
fails, the system will remain operational.
Caution: The AC power distribution within a rack ensures a balanced load to
each PDU and reduces the possibility of an overload condition. Changing the
cabling to or from a PDM could cause an overload condition. HP supports only
the AC power distributions defined in this user guide.
1 Power receptacles
