Troubleshooting
Diagnosing with the LEDs
Tip Problem
1 The access point
is not plugged
into an active AC
power source, or
the access
point's AC power
adapter may
have failed.
2 The access point
is not receiving
power from the
PoE source.
3 The access point
has experienced
a software
failure during
initialization.
4 Wireless link has
been
administratively
disabled.
5 The
10/100Base-TX
network
connection is not
working
properly.

Diagnostic Tips
1. Verify that the power cord is plugged into an active power source and to the access
point's AC power adapter. Make sure these connections are secure.
2. Try power-cycling the access point by unplugging and plugging the power cord back
in.
3. If the Power LED is still not on, verify that the AC power source works by plugging
another device into the outlet. Or try plugging the access point into a different outlet
or try a different power cord.
If the power source and power cord are OK and this condition persists, the access point's
AC power adapter may have failed. Call your HP-authorized network reseller, or use the
electronic support services from HP to get assistance.
1. Verify that access point's 10/100Base-TX 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.
After a power on or reset, the LEDs indicate stages of the system initialization. If there is
a software failure during initialization, the LED pattern indicates at which stage the failure
occurred. The normal LED sequence during initialization is as follows:
Stage 1. Power LED on. System initialization has started.
Stage 2. Both LAN LEDs blink once. The boot ROM has successfully initialized.
Stage 3. One LAN LED on. The operating system kernel has successfully loaded.
Stage 4. LAN LED on only. The operating system is mounting the file system.
Stage 5. LAN and 11a/b/g LEDs on. Radio drivers have been successfully loaded.
Stage 6. LAN, 11a/b/g, and 11b/g LEDs on. The access point software is initializing.
Stage 7. Normal LED operation. Initialization has completed successfully.
The entire initialization sequence takes between 30 seconds (normal reset) and one
minute (factory default reset). If one of the above LED patterns display longer than one
minute, a failure has occurred. Do the following:
1. Reset the access point by power cycling the access point.
2. If the fault indication reoccurs, take note of the LED pattern and contact your HP-
authorized network reseller, or use the electronic support services from HP to get
assistance.
Verify that the wireless port has not been disabled through an access point configuration
change. You can use the Web browser interface to determine the state of the wireless
port and re-enable the port if necessary. Also verify that the country/region code has
been set.
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.
• Verify duplex operation (see page 6-1).
• If these procedures don't resolve the problem, try using a different cable.
