The rear panel features components like an AC power socket, a security lock, an electrical ground point, and more.
These components are described in detail below.
This following table lists the front panel components on all the switches in the series:
Port Description
AC Power Connector
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.
Power Cord Retainer Hole
The power cord retainer hole is used to insert the power cord retainer to secure the
AC power cord.
Switch GND
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.
Security Lock
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.
