SECTION 6: WAM USE and TROUBLESHOOTING
Refer to the WAM Installation Guide (IRF or Cellular version) to perform initial WAM installation and testing.
WAM Use
Once installed, the WAM (including its integrated modem) automatically communicates with both VACs and the
PowerFleet Vision Pro system software. Normal operation does not require any further human interaction.
Note: Wi-Fi deployments do not require WAMs, however they can be used as supplemental communication.
LEDs of Fully Operational WAMs and Cellular Modems (if applicable)
System is running normally. Once installed, this LED should always be on, except during a
facility blackout. A yellow light means the unit is in sleep mode.
Ethernet port is connected. This light should always be on.
Blinks when valid Ethernet packet is received or transmitted. Green light should be
blinking if the Ethernet port is active.
On after boot-up. If flashing, then authorization is not transmitted.
No connectivity to the host computer.
WAM is sending data over the network to the host computer. Once installed,
this is expected behavior.
Connection is fine, but WAM does not have data to send. (e.g. No vehicles
nearby and no diagnostic data to send).
WAM is in remote control mode.
