overvoltage protection, and overcurrent protection.
The power supply is input rated at 90 to 264 volts alternating current (VAC). Power supply

Three cooling fans (two integrated in the power supply assembly) provide cooling for the power
supplies and CTP card, as well as redundancy for continued operation if a single fan fails.

terminal or dial-in connection for a remote terminal. Although the port is typically used by
authorized maintenance personnel, operations personnel can use the port to configure Edge
Switch network addresses.
