bcmxcp_usb - Man Page
Experimental driver for UPSes supporting the BCM/XCP protocol over USB
Synopsis
bcmxcp_usb -h
bcmxcp_usb -a UPS_NAME [OPTIONS]
Note
This man page only documents the hardware-specific features of the bcmxcp_usb driver. For information about the core driver, see nutupsdrv(8).
Note
This driver is a variant of the serial driver bcmxcp(8) and uses the same core code.
Supported Hardware
This driver should recognize all BCM/XCP-compatible UPSes 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.
Note
This driver does not currently support USB-matching settings common to other drivers, such as vendor, vendorid, product, productid, serial, device or bus.
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 information
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 = autoKnown 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.
