The following is a summary of how several screens in the Management
System can be used as diagnostic tools.
3.3.1 Starting Information Screen
( See
Starting Information Screen on Page 32
)
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 3-3
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 139 for
information on antenna system checks.
Table 3-3. 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.
