POWERMAN-PDU(8) 		   NUT Manual			 POWERMAN-PDU(8)

NAME
     powerman-pdu - Driver for Powerman PDU

SYNOPSIS
     powerman-pdu -h

     powerman-pdu -a PDU_NAME [OPTIONS]

	 Note

	 This man page only documents the hardware-specific features of the pow-
	 erman-pdu  driver.  For  information about the core driver, see nutups-
	 drv(8).

SUPPORTED HARDWARE
     This driver supports a wide range of PDUs through the Powerman project.

     This includes various models from APC, Baytech, Cyclades, but also  support
     IPMI and various blade management modules from HP, IBM and Sun.

EXTRA ARGUMENTS
     This driver doesn't support any optional settings.

INSTALLATION
     This  driver  may	be  not built by default. You can build it by installing
     prerequisites and using configure --with-powerman=yes.

UPS COMMANDS
     The following instant commands (see upscmd(8)) are available for each  out-
     let of the PDU, with X standing for the outlet number:

     outlet.X.load.on
	 Power on the outlet.

     outlet.X.load.off
	 Power off the outlet.

     outlet.X.load.cycle
	 Cycle the outlet (power off then power on, possibly with a delay).

IMPLEMENTATION
     The  hostname of the Powerman server is specified using the "port" value in
     ups.conf, i.e.:

	 [pdu]
		 driver = powerman-pdu
		 port = host.example.com:port

     The port used to reach powermand is optional if the default port is used.

KNOWN ISSUES
     In the current NUT version as of this writing (2.4.1), ups.status is  still
     exposed,  with  the value "WAIT". Some other values from the ups collection
     are also exposed.

   Using host names for UPS NMC
     An UPS network management card may be assigned a fixed/static IP address or
     a dynamic one (e.g. by DHCP) in your network. Due to this, you may want  or
     have  to use a dynamic naming service to access the UPS. Note that this may
     become a problem specifically during large outages and shutdowns, when your
     DHCP/DNS server might already go down while the driver needs to resolve the
     name involved (especially during late-shutdown hooks, when a  new	instance
     of  the  driver program might start just to tell the UPS to power off or to
     power-cycle).

     It may be wise to ensure your OS name service client can cache the UPS name
     sufficiently long,  or  to  use  fixed  IP  addressing  (and  an  entry  in
     /etc/hosts  for  good  measure,  so  you  only  have one spot to eventually
     re-configure this).
