properly. Try the following procedures:
• For the indicated port, verify that both ends of the cabling, at the unit and the connected
device, are connected properly.
• Verify the connected device and unit are both powered on and operating correctly.
• If the other procedures don’t resolve the problem, try using a different port or a different
cable.

EPS power is not
available. Check the log file of the connected switch for more detailed information. Try
disconnecting, then reconnecting the EPS cable. Wait three to four seconds for the device
to successfully communicate for EPS power. Also try another EPS cable. If this fails to
restore EPS power, call your HP-authorized LAN dealer, or use the electronic support
services from HP to get assistance. See the Customer Support/Warranty booklet for more
information.
