1. Verify that access point's 10/100Base-T port is attached to a PoE source device.
2. Verify that the PoE source device is powered on, and that the PoE function has been
administratively enabled on the source port attached to the access point.
3. Refer to Tip 6 to verify that the network cable is functioning properly.
1. Try resetting the access point by pressing the Reset button on the back of the access
point, or by power cycling the access point.
2. If the fault indication reoccurs, attach a console to the access point (as indicated in
chapter 2). Then, reset the access point. Messages should appear on the console
screen and in the console log identifying the error condition. You can view the console
log at that point by using the show logging commands.
If necessary to resolve the problem, contact 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.
Verify that the wireless port has not been disabled through a access point configuration
change. You can use the console interface, or, if you have configured an IP address on
the access point, use the web browser interface to determine the state of the wireless
port and re-enable the port if necessary.
Try the following procedures:
• Verify that both ends of the cabling, at the access point and the connected device, are
connected properly.
• Verify the connected device and access point are both powered on and operating
correctly.
• If the other procedures don't resolve the problem, try using a different cable.
VLAN configuration may affect the port operation. Use the access point's console to see
how the port is configured for VLANs.
For software troubleshooting tips, see the chapter "Troubleshooting" in the Management
and Configuration Guide, which is on the Documentation CD-ROM that came with your
access point.
Make sure also, that the device at the other end of the connection is indicating a good
link to the access point. If it is not, the problem may be with the cabling between the
devices or the connectors on the cable.
