AP does not power up
(Status LED is not
illuminated or flashing)
 When the AP is powered, the Status LED illuminates or flashes. If not,
check the Ethernet cable and connector for damage.
 Verify that the PoE injector is connected properly (i.e., the AP is
connected to Data + Power side).
 Verify that a nominal voltage of 48 VDC is present at the power
connector of the PoE.
 Verify that the PoE injector is not defective by substituting another
known working PoE.
 Verify that the backhaul cable from the Data connector on the PoE
injector is connected to a router, backhaul device, or laptop that is
powered up. Connectivity is not required but the port must be active.
 Contact On-Ramp for assistance
AP does not acquire GPS
 Verify that the GPS antenna cable and the AP antenna cable are
connected and have not been swapped. If the connectors were
swapped, it is necessary to power cycle the AP.
 Disconnect both ends of the GPS. Verify continuity and that the cable
is not shorted.
 Verify the GPS antenna is not defective by substituting a known
working GPS antenna.
 Contact On-Ramp for assistance.
Link problem
 Is the Link LED blinking? If not, check the Ethernet cable and
connector for damage.
 Verify that the PoE injector is connected to the WAN.
 Connect a properly configured laptop to the data port on the PoE, as
described in chapter 8, and attempt to log into the AP. If successful,
troubleshoot the backhaul.
 Contact Ingenu for assistance.
