TROUBLESHOOTING
Successful troubleshooting of a wireless system is not difficult, but
requires a logical approach. It is best to begin troubleshooting at the
Access Point unit, as the rest of the system depends on the Access Point
for synchronization data. If the Access Point has problems, the operation
of the entire wireless network will be affected.
When communication problems are found, it is good practice to begin
by checking the simple things. Applying basic troubleshooting tech-
niques in a logical progression can identify many problems.
Multiple
Communication
Layers
It is important to remember the operation of the network is built upon a
radio communications link. On top of that are two data levels— wireless
MAC, and the data layer. It is essential that the wireless aspect of the
Access Point and the Remotes units to be associated are operating prop-
erly before data-layer traffic will function.
Unit Configuration
There are over 50 user-configurable parameters in the entraNET Man-
agement System. Do not overlook the possibility that human-error may
be the cause of the problem. With so many possible things to look at and
change, a parameter may be incorrectly set, and then what was changed
is forgotten.
To help you avoid these problems, we recommend creating an archive
of the transceiver’s profile when your installation is complete in a Con-
figuration File. This file can be reloaded into the transceiver to restore
the unit to the factory defaults or your unique profile. For details on cre-
ating and archiving Configuration Files,
See “Using Configuration Scripts” on Page 64
Factory Assistance
If problems cannot be resolved using the guidance provided here,
review the MDS Web site’s technical support area for recent soft-
ware/firmware updates, general troubleshooting help, and service infor-
mation. Additional help is available through the MDS Technical
Support Department. (See “TECHNICAL ASSISTANCE” on the inside
of the rear cover.)
4.1.1 Interpreting the Front Panel LEDs
An important set of troubleshooting tools are the LED status indicators
on the front panel of case. They should be the first thing to check when-
ever a problem is suspected.
