Installing and Configuring the Core Switch 2/64
44 Core Switch 2/64 V4.1 Installation Guide
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.
Two jumper cables (C19 – C20) are provided to connect from the switch to the
PDU. The recommended PDU is E7671A. Two E7671A PDUs are recommended
for power redundancy. The recommended power cords to connect from the PDU
to the wall are E7803A, E7805A, E7806A, E7808A, E7809A.
It is not recommended to connect the switch to the wall because it would require
two dedicated wall outlets. Using the PDU, a customer can connect more devices
to a power source.
Installing the Switch as a Stand-alone Unit
The following items are required for this setup:
■
Core Switch 2/64
■
AC power cords and cables supplied with the switch
Caution: You must remove the chassis door before lifting the chassis off the
pallet. See the next section, Removing the Chassis Door , on page 45.
