grounded and that there is a valid ground connection between the chassis of the switch and the
rack. Test the ground using an Ohm meter.
1.3.3 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 100 - 240 VAC, 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.
Some national and/or local codes may require IT components to be bonded and exter-
nally grounded (not including the power cord ground). You must follow all national
and local codes when installing this equipment.
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 Connector LEDS are off to
ensure a powered down status.
