Troubleshooting

The Harmony 802.11a Access Point is designed to be very easy to install and operate. 
However, if you experience difficulties, use the information in this chapter to help 
diagnose and solve problems.  Also, if you have an AP Controller, refer to the 

Harmony 

Access Point Controller User’s Guide for additional troubleshooting suggestions.

If you cannot resolve a problem, contact Proxim Technical Support.  See “Technical 
Support and Training” on page 53.

If you require assistance to install your local network, Proxim can put you in contact 
with a Harmony reseller in your area.  The reseller is an expert in the design, 
installation, and maintenance of local area networks and will be able to examine your 
needs and recommend the most cost-effective solution for you, whether you are 
installing a new network or adding on to an existing one.  For the location of the 
Harmony reseller nearest you, contact Proxim at 1-800-229-1630 and ask for the Sales 
Department.

LED Error Codes

The Status LED on the top of the Harmony 802.11a Access Point will flash red in a 
repeating pattern to indicate the following errors: 

1 blink ..............................................Memory error

2 blinks............................................Flash write error

3 blinks............................................Ethernet initialization error

4 blinks............................................Radio initialization error 

If you see any of the above flashing sequences, recycle power to the Access Point.  If 
the flashing sequence persists after you have reset the unit, make a note of which of 
the above patterns you have and contact Proxim Technical Support.
