Battery Backup

Supplies power long enough for equipment to properly shut down when utility power fails. Helps prevent loss of data and minimizes the component stress caused by a hard shutdown.

Blackout

A power failure in which line voltage drops to zero.

Boost

The AVR function of a UPS which increases voltage when the utility power approaches the low voltage threshold.

Brownout

A drop in voltage for an extended period of time.

Buck

The AVR function of a UPS which reduces voltage when the utility power approaches the high voltage threshold.

Buck/Boost

Full automatic voltage regulation in a UPS stabilizes low voltage (boost) and high voltage (buck) to maintain nominal 120V power without resorting to battery power when minor power fluctuations occur.

Capacity

The current battery charge, expressed as a percentage of a full charge.

Cisco Compatible

Means that a product meets the standards set by Cisco, a global leader in IT.

Coaxial Cables

Cables that are made of an inner conductor surrounded by an insulator and a shield. Generally used for TV antennas, satellite dishes, cable modems, and certain computer networking applications.

Communication Interface

Alarm Telemetry to an optical network terminal or a connected device. Contact closure alarm with NC normal state.
