Rack-Type System Unit Power
The racks for rack-type system units are supplied with a PDU and a pluggable power cord. A rack can
contain up to four vertically mounted ac PDUs. Two additional PDUs can be mounted horizontally in the
bottom rear of a 7014 T00 rack, and three additional PDUs can be mounted horizontally in the bottom rear
of a 7014 T42 rack.
Note: For information about connecting power cables to PDUs in the rack, refer to the7014 T00 and T42
Rack Installation and Service Guide, order number SA23-2544, and Site and Hardware Planning
Information, this publication.
There are two types of ac PDUs: Type 6 and Type 7.
v Type 6 PDUs have six IEC320-C13, 200 V to 240 V ac outlets on the rear of the PDU. There are two
additional IEC320-C13, 200 V to 240 V ac outlets (with limited access) on the front of the PDUs. These
two additional outlets are intended for IBM service. The input ac power to the bus is not switched, so
each outlet has a separate circuit breaker to protect against excessive current. Each outlet on the Type
6 PDU is limited to 8 amps, and the PDU is limited to a total of 24 amps. Type 6 PDU feature codes are
9171, 9173, 9174, and 6xxx. For additional information about Type 6 PDUs, see the illustration “Type 6
Power Distribution Unit” on page 342.
v Type 7 PDUs have nine IEC320-C13, 200 V to 240 V ac outlets and two IEC320-C19, 200 V to 240 V
ac outlets. The input ac power to the bus is not switched, so each group of three IEC320-C13, 200 V to
240 V ac outlets has a separate circuit breaker to protect against excessive current. Each IEC320-C19,
200 V to 240 V ac outlet has a separate circuit breaker. Each outlet of Type 7 PDUs is limited to 10
amps. Each group of three outlets in Type 7 PDUs is limited to 15 amps. The three-phase Type 7 PDU
is limited to 16 amps per phase, and the PDU is limited to a total of 24 amps. Type 7 PDUs feature
codes are 9176, 9177, 9178, 7176, 7177, and 7178. For additional information about Type 7 PDUs, see
the illustration “Type 7 Power Distribution Unit” on page 343.
