Internal Power Supply
All the switches except Catalyst 3560CX-8PT-S are powered through their internal power supplies. The
internal power supply is an autoranging unit that supports input voltages between 100 and 240 VAC. 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.
