Power distribution unit
The following figure shows the four vertical PDU locations in a rack.
Power distribution units (PDUs) are required with 7014-T00, 7014-T42 IBM racks and optional with
7014-B42, 0553, and 0555 racks, except with a 0578 or 0588 expansion unit. If a PDU is not defaulted or
ordered, a power cord is provided with each individual rack-mounted drawer for connection to a
country-specific utility mains receptacle or uninterruptible power supply. See the individual
rack-mounted drawer specifications for the appropriate power cords.
