Grounding the Chassis
The switch chassis must be connected to ground to ensure proper operation and to
meet electromagnetic interference (EMI) and safety requirements.
The switch chassis is connected internally to 0 V, which is then grounded through an
installed AC PSU when it is connected to a grounded AC power outlet by an AC power
cord.
There are no grounding points on the switch that require a connection to a rack ground
or other earth ground.
How to Connect to AC Power
To supply AC power to the switch, first verify that the external AC power supply can
provide 100 to 240 VAC, 50-60 Hz, 3 A minimum.
NOTE: For electrical safety purposes, please pay attention to the following warning notices,
printed on the switch unit.
