1 Introducing the BPS-120
The BPS-120 is a backup power system to which you can connect up to six of ZyXEL’s devices that have a 12VDC external backup power supply connector. The BPS-120 monitors the power status of the connected devices and immediately provides backup power to a device that loses power or has a hardware power failure. The BPS-120 can supply power to one device at a time.

The BPS-120 has the following features:
•Six (6) output power ports for connecting devices.
•Individual front-panel LEDs to show status for each output power port, internal power hardware, internal fans, and internal temperature.
•Fast power switchover ensures that a power failure on a connected device does not cause it to restart.
•Reduced form factor facilitates rack mounting and high-density deployment.
