Power switch
Allows you to turn the appliance on or off.
AC power
Enables you to connect the appliance (using the supplied power
cord) to a 100 to 240VAC (50/60Hz) power source. The power
supply can auto-detect 110/220 voltage.
DB-9 interface
Allows you to use the RS-232 cable provided in the package to
connect the appliance to an Uninterruptable Power Supply (UPS).
This type of connection enables UPS devices to notify the
appliance if the power goes out, prompting the appliance to shut
itself down properly.
UPS devices from American Power Company (APC) are currently
supported by the Firebox Vclass power management firmware.
Check the WatchGuard Web site (www.watchguard.com) for
updated information on complete UPS support.
