Internal Power Supply
All the switches are powered through their internal power supplies. The internal power supply is an autoranging
unit that supports input voltages between 100 and 240 VAC (max of 90V to 264V). The AC frequency range
of the power supply is 50Hz~60Hz. Plug the AC power cord into the AC power connector and into an AC
power outlet.
Security Slot
The switches have security slots on the rear panel. You can install an optional cable lock, such as the type
that is used to secure a laptop computer, to secure the switch.
