Problem
No power to radio
Fiber light lit at radio but not on network equipment
Cannot establish the wireless link
Possible Cause
Wrong polarity of supply voltage
The supply voltage measured at the radio (when connected) is below 15Vdc
LSP is enabled and radio link is down.
TX and RX fibers are swapped.
Error in the configuration of the networking equipment.
One or both of the fibers have been damaged or is not connected at both ends.
Units are not properly aligned
Obstacle in link
Resolution
Use a DVM to determine the polarity and voltage on the DC cable. (See Section 2.6)
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 Section 2.6)
This is normal behavior.
Try swapping the TX and RX fibers at one/both ends of the connection.
Verify the configuration of the network equipment is consistent with radio unit’s fiber port settings (autonegotiation and flow control).
Use a loopback connector at the radio to verify the radio is OK, repeat at the networking equipment. Visually inspect the fiber cable.
The two units are not set to the same polarization. Verify and if necessary correct the polarization setting. (See Section 3.6)
Verify the line of sight conditions and check for required clearance (See Section 2.3).
