ground. If you choose to not use the ground screw, make sure that there is a valid ground connec-
tion between the chassis of the switch and the rack. Test the ground using an Ohm meter.

2.2.4 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 PSU may be installed at a later time. Each supply has a separate AC receptacle.
The input voltage is auto-adjusting for 90-264 VAC, 47-63Hz power connections. The power
cords should be standard 3-wire AC power cords including a safety ground and rated for 15A or
higher.
Note: 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 PSU in the
switch.
CAUTION
Risk of electric shock and energy
hazard. The two PSUs are inde-
pendent.
Disconnect all power supplies to
ensure a powered down state
inside of the switch platform.

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.
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 LEDS are off to ensure
a powered down status.
