# bcmxcp(8)

Driver for UPSes supporting the serial BCM/XCP protocol

## NAME

bcmxcp - Driver for UPSes supporting the serial BCM/XCP protocol

## SYNOPSIS

**bcmxcp** -h

**bcmxcp** -a *UPS\_NAME* \[*OPTIONS*\]

**Note**\

This man page only documents the hardware-specific features of the bcmxcp driver. For information about the core driver, see [**nutupsdrv**(8)](/nutupsdrv/8.md).

## SUPPORTED HARDWARE

This driver should recognize all serial BCM/XCP-compatible UPSes. It has been developed and tested on Powerware PW5115 and PW9120 hardware.

If your UPS has a USB connection, you may also consult the [**bcmxcp\_usb**(8)](/bcmxcp_usb/8.md) driver documentation.

## EXTRA ARGUMENTS

This driver supports the following optional settings in the [**ups.conf**(5)](/ups.conf/5.md).

**shutdown\_delay=***delay*

The number of seconds that the UPS should wait between receiving the shutdown command (upsdrvctl shutdown) and actually shutting off.

**baud\_rate=***rate*

Communication speed for the UPS. If this is set to 9600, it tries to connect to the UPS at 9600bps. If it fails to communicate, it will go into baud-hunting. It starts at 1200 and goes up to 19200. If it succeeds, it tell you the speed it connected with. If not included in the config, it defaults to baud-hunting.

## DEFAULT VALUES FOR THE EXTRA ARGUMENTS

• **shutdown\_delay =** *120*

• **baud\_rate =** *none*

## INSTANT COMMANDS

This driver supports the following Instant Commands:

**shutdown.return**

Turn off the load and return when power is back.

**shutdown.stayoff**

Turn off the load and remain off.

**test.battery.start**

Start a battery test.

**outlet.n.shutdown.return**

Turn off the load on outlet *n* and return when power is back. (*n* is the outlet number reported by the upsc command)

## TODO LIST

Report UPS statistics information

BCM/XCP supports reporting of UPS statistics data.

## BUGS

None known.
