You can power the switch with either one or two DC power supplies. For
power supply specifications, refer to "Power Supplies" on page 48.
Power supplies are connected to the 4-wire, DC power connector on the
top panel of the switch. Refer to Figure 41. A power supply is connected to
the switch with two wires, one positive (+) and one negative (-). If you are
installing only one power supply to the switch, you may connect it to either
the PWR 1 or PWR 2 connector.
