Faulty or loose cables. Look for loose or obviously faulty connections.
If the cables appear to be OK, make sure the connections are secure. If
that does not correct the problem, try a different cable.
Connection topologies. It is important to make sure you have a valid
connection topology. The HP 600 RPS/EPS can support two HP PoE
devices on its EPS ports, but with limited power output. Up to six HP
ProCurve switches can be connected to RPS ports, but only one can be
supplied power based on port priority. The HP 610 EPS can support four
HP PoE devices on its EPS ports, but with limited power output on each
port pair. The HP 610 EPS units can be connected together to supply
backup power to other units. However, the power load on the units must
be limited so that there is still enough power to support a failed unit.
Sample topologies are shown at the end of
Power limitations. Be sure to understand the power limitations of the
HP 600 RPS/EPS and HP 610 EPS when connecting switches. An overload
condition on a port causes the port to be shut down.
