TROUBLESHOOTING
Successful troubleshooting of a wireless system is not difficult, but
requires a logical approach. It is best to begin troubleshooting at the AP
radio, as the rest of the system depends on the AP for synchronization
data. If the AP has problems, the operation of the entire wireless net-
work is 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. The wireless aspect of the AP and the Remotes
radios to be connected must operating properly so data-layer traffic can
function.
Radio Configuration
There are over 50 parameters in the entraNET MS. With so many set-
tings, 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 profile when your installation is complete in a Config-
uration File. This file can be reloaded into the transceiver to restore the
radio to the factory defaults or to known working settings. For details on
creating and archiving Configuration Files,
see “ PING Utility Menu”
on Page 89
.
MDS Assistance
If problems cannot be resolved using the guidance provided here,
review the MDS Web site’s technical support area for recent software or
firmware updates, general troubleshooting help, and service informa-
tion. Additional help is available through the MDS Technical Support
Department. (See TECHNICAL ASSISTANCE on the inside of the rear
cover.)
7.1.1 Interpreting the Front Panel LEDs
An important set of troubleshooting tools are the LED status indicators
on the front panel of the transceiver. They should be checked whenever
a problem is suspected.
Table 2-2 on Page 26
describes the function of
each status LED.
Table 7-1
below provides suggestions for resolving
common system difficulties using the LEDs, and
Table 7-3
provides
other simple techniques.
