The following is a summary of how several screens in the Management
System can be used as diagnostic tools. For information on how to con-
nect to the Management System
See
“STEP 3—CONNECT PC TO THE
TRANSCEIVER”

The Management System’s “homepage” provides some valuable bits of
data. One of the most important is the “Device Status” field. This item
will tell you if the unit is showing signs of life.
If the
Device Status
field says “associated,” then look in the network
areas beginning with network data statistics. If it displays some other
message, such as
Scanning
,
Hop Sync
or
Alarmed
, you will need to
determine why it is in this state.
The Scanning state indicates a Remote unit is looking for an Access
Point beacon signal to lock onto. It should move to the Hop Sync and
finally to the Associated state within less than a minute. If this Remote
unit is not providing reliable service, look at the
Event Logs
for signs of
lost association with the Access Point or low signal alarms.
Table 4-3
provides a description of the Device Status messages.
If the Remote is in an “Alarmed” state, the unit may still be operational
and associated. Look for the association state in the
Wireless Network
Status
screen to determine if the unit is associated. If it is, then look at
the
Error Log
for possible clues.
If the unit is in an “Alarmed” state and not able to associate with an
Access Point unit, then there may be problem with the wireless network
layer. Call in a radio technician to deal with wireless issues. Refer the
technician to the
RADIO (RF) MEASUREMENTS
on Page 132
for infor-
mation on antenna system checks.
Table 4-3. Device Status

1. Available in the
Startup Information Screen
or the
Wireless Status Screen
at
the Remotes.
Scanning
The unit is looking for an Access Point beacon signal. If
this is a Remote radio,
Associated
means that this unit is
associated with an Access Point
Hop Sync
The unit has found a valid beacon signal for its network
and has changed its frequency hopping pattern to match
that of the AP.
Connected
The unit has established a radio (RF) connection with the
Access Point, but has not obtained cyber-security
clearance to pass data.
Associated
This unit has successfully synchronized and is
“associated” with an Access Point. This is the normal
operating state.
Alarmed
The unit is has detected one or more alarms that have not
been cleared.
