4. Point-to-Point Backhaul

Install and Troubleshoot

Ɣ Use labels to ensure that the correct radios are in the correct positions.

Ɣ Install the Access Point (A) radios are at the top of the pole, and the Station (S)

radios on the same pole are at least three feet below the Access Point radios as

shown in “Radio-to-Radio Communication” on page 68.

Ɣ Point radio pairs directly at each other where possible (see “Maintain Line-of-Sight”

on page 77). Some inaccuracy is tolerable; however, align the radios as close as

possible using binoculars or compass bearing.

2 From the recording truck, open the Ubiquiti Discovery Tool. Verify that all of the radios

are listed, and verify that each of the radios has a valid IP Address. Note the following:

Ɣ If a radio is listed, that means there is an Ethernet path to the radio.

Ɣ If a radio has a valid IP address that means the DHCP is active, DHCP is being

accepted by the radios, and DHCP is being passed from radio link to radio link.

Ź DHCP server-assigned IP addresses are 10.xxx.xxx.xxx

Ź Non-DHCP server-assigned IP addresses are 192.168.1.xxx

3 If a radio is not listed, send a troubleshooter to the first radio that is not listed (the radio

closest to the recording truck) and perform the following steps:

a Verify that the LIU has active LED lights (the battery has power).

b Verify that the radio is visible in Discovery.

c Verify that the radio is securely connected to the LIU with a known-good cable.

d Connect a laptop to the LIU.

IMPORTANT: The Ethernet ports on the LIU are PoE enabled. When connecting a

laptop computer to the LIU, use a non-powered cable (60-0039) to protect the

computer’s Ethernet port. Do not use a powered Ethernet cable (60-0054). See

“Ethernet Cable Connections Comparison” on page 80 for more information.

e Open the discovery tool and verify that the radio is listed. If the radio is not listed,

perform the following steps.

1) Verify that the radio has power by visually inspecting the LEDs.

2) If the radio has power but is not visible to the laptop, try a different Ethernet

port.

3) If the radio does not have power, troubleshoot the power and/or replace the

radio.

f Verify that the radio is pointed in the direction of its partner (pair) radio and has

reasonable line-of-sight to its partner (pair) (see “Maintain Line-of-Sight” on page

77).

g Verify that the last radio visible from the doghouse is pointed in the correct direction.

h Reload the configuration file to the radio.

i If the above steps fail, contact Wireless Seismic, Inc. for assistance.
