Power Connections and Initial Power On
The switch platform ships with one or two power supply units. For switches with only one unit
installed, a second PS unit may be installed at a later time. Each supply has a separate AC recep-
tacle. The input voltage is auto-adjusting for 100 - 240VAC, 50-60Hz power connections. The
power cords should be standard 3-wire AC power cords including a safety ground and rated for
15A or higher.
Figure 23: Two Power Inlets - Electric Caution Notifications
Caution: The switch platform will automatically power on when AC power is applied.
There is no power switch. Check all boards, power supplies, and fan tray modules for
proper insertion before plugging in a power cable.
This unit is intended for installation in a Restricted Access Location. A restricted
access area can be accessed only through the use of a special tool, lock and key, or
other means of security.
Caution: After inserting a power cable and confirming the green system status LED
light is on; make sure that the Fan Status indicator shows green.
If the fan status indicator is not green then unplug the power connection and check that
the fan module is inserted properly and that the mating connector of the fan unit is free
of any dirt and/or obstacles.
Caution: When turning off the switch, make sure ALL Connector LEDS are off to
ensure a powered down status.
Do not hot swap the power supply if your switch has only one power supply. You must
power down the system to replace the power supply unit when there is only one PS
unit in the switch.
CAUTION
Risk of electric shock and energy
hazard. The two PS units are
independent.
Disconnect all power supplies to
ensure a powered down state
inside of the switch platform.
