Description
The AC power cord (included in the package) can be plugged into this receptacle
to supply the switch with 100-240 VAC power at 50-60 Hz.
The power cord retainer hole is used to insert the power cord retainer to secure the
AC power cord.
Use an electrical grounding wire and connect one end of the wire to the switch
GND and the other end of the wire to an electrical grounding point most commonly
found on the Switch mounting rack itself.
The Kensington-compatible security lock can be used to connect the Switch to a
secure immovable device. Insert the lock into the notch and turn the key to secure
the lock. The lock-and-cable apparatus should be purchased separately.
