Figure 4-5 LED Indicators
Normal Indications
When power is first applied, the following events occur in a normally working unit:
•
All front panel indicators light briefly
•
The
ACTIVE LED
for the selected transceiver board lights.
•
On SD radio modules, The
Power LED
will begin to flash indicating they have not yet
communicated with the platform manager.
•
The
Power LED
and
Alarm LED
will light on the Platform Manager card. At this point the
platform manager is performing a pre-boot validation of the firmware to ensure that all
required security signatures are in place and valid.
•
The
Alarm LED
will turn off and the
Power LED
will begin to flash. At this point the platform
manager is booting and initializing the system.
•
Once the platform manager initializes the transceiver module, the
Power LED
will stop
flashing and turn solid.
Maximizing RSSI
Since the Master Station almost always uses an omni-directional antenna, maximizing signal
strength is done at the remote sites where directional antennas are typically used. An RSSI
stronger than -90 dBm is desirable. Refer to Section 5.0
Device Management for information on
monitoring the RSSI for the Radio Module.
