MDS 05-6399A01, Rev. D MDS Master Station 31
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 Device Management for information on monitoring the RSSI for the Radio
Module.
