HP StorageWorks SAN Director Installation Guide (A7393-90009, May 2007)

Installing and configuring the 4/256 SAN Director38
Power requirements
Two AC power cords connect to the switch. The AC power source must meet these requirements:
NOTE: Installing each power cord using two separate sources ensures power supply redundancy.
• 200 to 240 VAC, 50–60 Hertz
• Protected by a circuit breaker in accordance with local electrical codes
• Supply circuit, line fusing, and wire size that are adequate according to the electrical rating on
the chassis nameplate
• Grounded AC outlets installed by a licensed electrician and compatible with the power cords
The switch includes a universal power supply capable of functioning worldwide without voltage
jumpers or switches. The power supply is auto ranging in terms of accommodating input voltages
and line frequencies.
HP recommends connecting two optional Power Distribution Units (PDUs) to the switch for power
redundancy. The recommended PDU is E7671A. HP recommends that you do not connect the switch
to the wall, because it would require two dedicated wall outlets. Using the PDU, you can connect
more devices to a power source.
Two jumper cables (C19-C20) are provided to connect from the switch to the PDU. The
recommended power cords to connect from the PDU to the wall are E7803A, E7805A, E7806A,
E7808A, and E7809A.
Setup tasks and estimated time required
Table 6 describes the main installation and setup tasks and the estimated time required for each,
based on a fully populated 4/256 SAN Director (with 384 Fibre Channel ports). Configurations
containing fewer than 384 ports require less time. These time estimates assume a prepared
installation site and appropriate power and network connectivity.
