We have recently been assigned to help with the development
of a system that will power non-computer/non-network devices
located at various places within a 10,000 square ft facility.
Most of these devices will operate on a fairly wide range of
DC input power.

The availability of surplus Cat-5 cable and the availability
of low cost POE switches has been suggested as a method of
powering these devices.  There also appears to be some good,
low cost installation options for all of the required system

The activity and health of the devices is directly related
to their power consumption. Is there a standard CentOS feature
or commonly used App that would facilitate monitoring the power
being supplied by each of the individual POE switch outputs?  

Thanks in advance for any information shared.
