Basic Troubleshooting Tips

Most problems are caused by the following situations. Check for these items

first when starting your troubleshooting:

■ 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 switches on its EPS

ports, but with limited power output. Up to six HP switches can be

connected to the RPS ports, but only one switch can be supplied

power based on the RPS port priority scheme for the HP 600 RPS/EPS.

• The HP 610 EPS can support four HP PoE switches 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 on page 5-26 in this book.
