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.
