BCMXCP_USB(8)
NAME
bcmxcp - Experimental driver for UPS'es supporting the BCM/XCP protocol
over USB
NOTE
This man page only documents the hardware-specific features of the
bcmxcp_usb driver. For information about the core driver, see nutupsdrv(8). This driver is a variant of the serial driver bcmxcp and uses
the same core code.
SUPPORTED HARDWARE
This driver should recognize all BCM/XCP-compatible UPS'es that are
connected via USB. It has been developed and tested on Powerware
PW3501 hardware. It also has been tested on PW5110 hardware.
EXTRA ARGUMENTS
This driver supports the following optional settings in the
ups.conf(5).
- shutdown_delay=delay
- The number of seconds that the UPS should wait between receiving the shutdown command and actually shutting off.
DEFAULT VALUES FOR THE EXTRA ARGUMENTS
shutdown_delay = 120
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.
TODO LIST
- Report UPS alarm status
- BCM/XCP supports reporting a wide range of UPS alarm conditions.
- Report UPS statistics informations
- BCM/XCP supports reporting of UPS statistics data.
EXPERIMENTAL DRIVER
This driver has been tagged experimental, even if it has been reported
to be stable. Thus it is not suitable for production systems and it is
not built by default. This is mainly due to the fact that it is a new
driver.
INSTALLATION
This driver is not built by default. You can build it by using "configure --with-usb=yes". Note that it will also install other USB drivers.
You also need to install manually the hotplug files (libhidups and libhid.usermap), generally in etc/hotplug/usb/, to address the permission
settings problem. Lastly note that the libhidups file must have execution flag set (ie using chmod +x ...).
IMPLEMENTATION
- bcmxcp_usb only supports 1 UPS at this time. You can put the "auto"
value for port in ups.conf, i.e.:
- [pw3105]
driver = bcmxcp_usb
port = auto
KNOWN ISSUES AND BUGS
- Got EPERM: Operation not permitted upon driver startup
- You have forgotten to install the hotplug files, as explained in the INSTALLATION section above. Don't forget to restart hotplug so that it applies these changes.
