Problem: No Ethernet Link light on Power IDU
Solution: Check CAT5e cable to verify wired straight through
Try swapping out PIDU to rule out PIDU.
Try swapping out cable with known good cable.
What do you see on the PIDU LED’s (power-Led solid green which is normal or
something else…if flashing disconnect power). Ethernet LED/ should flash 10 times on
startup to indicate the correct startup sequence has occurred and then go solid amber.
Problem: No RF link, lots of interference on one end of the link
(orange bars on the spectrum management page)
Solution: Enable Asymmetric DFS and re-run the installation wizard and:
- Insure range is set the same on both master and slave radios
- Verify target MAC address
- Verify AES keys match if applicable
Problem: Slow throughput only 1.5 Mbps across the link
Solution: Disarm the installation agent. During installation the radio modulation is fixed at BPSK
1.5Mbps and TX power is +24dBm
Problem: Can not ping or manage the radio, forgot the IP address, and forgot the password
Solution: Reset factory IP (Master 169.254.1.2) (Slave 169.254.1.1) by powering up radio, then
press and hold reset button on the Power IDU for 20 seconds. This will reset the IP and
password (no password) and default to Slave.
Problem: Still can not get the radio to behave properly after visiting the Canopy Knowledge Base
and following the detailed trouble shooting guide found in the User Guide.
Solution: Reset radio to “Gold Code” (Factory default settings) by pressing and holding the
Power IDU reset button while applying power, continue to hold for 45 seconds. This resets the
radio back to “Gold Code”, then upgrade to the current version of firmware.
Default IP will be (Master 169.254.1.2) (Slave 169.254.1.1)
Problem: Incorrect mounting/installation procedures with the OFDM Backhaul.
Solution: Verify existing BH pole mount installations were performed correctly and in
accordance with mounting instructions outlined in the Users Guide. Verify that the twist section
(wall mount only) assembly has not been used for pole mounting the ODU.
The ODU rear mounting bracket should never be removed or repositioned for any reason as part
of the normal mounting/installation procedures for the ODU. Some customers have repositioned
the rear mounting bracket of the ODU 90 Deg from the original factory position to allow the
improper use of the twist section (wall mount only) assembly for a pole mounting. The twist
section should only be used for wall mounting and never for pole mounting. Incorrectly using the
twist section for pole mounts in this manner will make the ODU less stable and more prone to
wind induced vibration.
