5 Troubleshooting
The following table provides a summary of possible problems you might encounter while
installing a BridgeWave GE/AR80 link, along with possible causes and their solutions.
Problem Possible Cause Resolution
Wrong polarity of supply
voltage
Use a DVM to determine the
polarity and voltage on the DC
cable. (See page12)
No power to radio
The supply voltage measured
at the radio (when
connected) is below 15VDC
The cable run is too long or the
cable gauge is too small.
Shorten the length of the cable
or use larger gauge cable. (See
page 12)
Radio link is down and/or
fiber not connected between
remote radio and network
equipment.
This is normal behavior.
Complete end-to-end
installation and re-check.
TX and RX fiber swapped Try swapping the TX and RX
fibers at one/both ends of the
connection
Error in the configuration of
the Networking equipment
Verify the configuration of the
network equipment:
Port is turned on and set to
1000Mbps Full Duplex and auto
negotiation is turned off.
Fiber light lit at radio
but not on network
equipment
One or both of the fibers
have been damaged
Use a loopback connector at the
radio to verify the radio is OK,
repeat at the networking
equipment. Visually inspect the
fiber cable.
Units are not properly
aligned
The two units are not set to the
same polarization. Verify and if
necessary correct the
polarization setting. (See
section 3.6)
Radio Link Up LED is
off
Obstacle in link Verify the Line of Sight
conditions and check for
required clearance (See page 8
for clearance distances).
