Starting Information Screen on Page 42

The Management System’s home page provides some valuable bits of
data. One of the most important is the
Device Status
field. This item tells
you if the unit is operational.
If the
Device Status
field says
Associated
, then look in the network areas
beginning with network data statistics. If it displays some other mes-
sage, such as
Scanning
,
Connecting
, or
Alarmed
, you must 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 Connecting state
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 might 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, look at the
Error Log for possible clues.
If the unit is in an Alarmed state and is not associated with an Access
Point, then there might be a problem with the wireless network layer.
Call a radio technician to deal with wireless issues. Refer the technician
to the
RADIO (RF) MEASUREMENTS on Page 157
for information on
antenna system checks.
Table 4-3. Device Status

1. Device Status is available in the
Startup Information Screen
or the
Wireless Status
Screen
at Remotes.
Scanning
The unit is looking for an Access Point beacon signal.
Ranging
Remote has detected AP and is synchronizing to it.
Connecting
The Remote has established a radio (RF) connection
with the Access Point and is negotiating the network
layer connectivity.
Authenticating
2
2. If Device Authentication is enabled.
The Remote is authenticating itself to the network to
obtain cyber-security clearance in order 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 has detected one or more alarms that have not
been cleared.
