Installing a PDU in a Cabinet
You can install one or two pairs of PDUs in a cabinet, for a total of four PDUs. Install
the first pair of PDUs in the bottom two contiguous one-U locations of the cabinet, and
the second pair in two convenient, contiguous one-U locations in the middle of the
cabinet.
For each pair of PDUs, the PDU in the top U provides A-side power. That is, the PDU
in the top location powers one CPU- I ⁄ O enclosure, and is the only source of power to
KVM switches. The PDU in the bottom location provides B-side power. That is, the PDU
in the bottom U provides power to the other CPU- I ⁄ O enclosure and to the other side
of an external storage enclosure.
Removable fasteners attach two reversible mounting brackets to the body of the PDU.
Eight mounting holes on the PDU let you adjust the bracket.
