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.

Power Connections and Initial Power On
The switch platform ships with one Power Supply Unit. The input voltage is auto-adjusting for
100 - 240 VAC, 50-60Hz power connections. The power cord should be standard 3-wire AC
power cord including a safety ground and rated for 15A or higher.

Extracting and Inserting the Power Supply Unit
Figure 20: Power Supply Unit Extraction
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 to use the shut down procedure.
Power supply unit has directional air flow similar to the fan module. The Fan module
airflow must coincide with the airflow of the PSU. If the PSU airflow direction is dif-
ferent from the fan module airflow direction the system will shut down.
