5. Point-to-Multipoint Backhaul
Install and Troubleshoot
5.4.1 Using one Recorder Radio
This section describes how the steps to configure one recorder radio, and multiple line station
radios.
To install and troubleshoot the radios:
1
Using the plan created in “Create Plan and Map” on page 111, install all of the radios,
masts, and LIUs. Point radio pairs directly at each other where possible (see “Maintain
Line-of-Sight” on page 112). Some inaccuracy is tolerable; however, align the radios as
close as possible using binoculars or compass bearing.
2
If your configuration includes a redundant recorder radio, do not supply power to it yet
(RECORDER_B).
3
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 line station 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 the recorder radio.
Ź
DHCP server-assigned IP addresses are 10.xxx.xxx.xxx
Ź
Non-DHCP server-assigned IP addresses are 192.168.1.xxx
4
If the recorder radio is the only radio listed, the problem is probably at the recorder
radio. Perform the following steps:
a
Verify that the recorder radio is connected to the antenna.
b
Verify that the antenna mast is elevated to the correct height
c
Verify that the recorder radio has DHCP by validating the IP address displayed in the
Ubiquiti Discovery tool. It should not be 192.168.1.20 (factory default). If it is
192.168.1.20, contact Wireless Seismic for DHCP support.
d
Reload the configuration file on the recorder radio.
e
If the recorder radio is still the only radio listed, proceed to the line station radios.
5
If a line station radio is not listed, send a troubleshooter to the radio that is not listed
and perform the following steps:
a
Verify that the line station radio is securely connected to the LIU with a known-good
cable.
b
Verify that the LIU has active LED lights (the battery has power).
c
Verify that the LIU has a flashing LNK LED. Note the following:
Ź
A flashing LNK LED confirms that the LIU can communicate over the network and
obtain an IP address through DHCP.
Ź
This step helps identify the exact location in the network where communications
are broken by proving the network is active between the two radios on a specific
pole.
Ź
If the LNK LED is not flashing, replace the Ethernet cable.
Ź
If the LNK LED is still not flashing, replace the battery.
Ź
If the LNK LED is still not flashing, reload the radio configuration file.
Ź
If the LNK LED is still not flashing, replace the LIU.
d
Verify that a known-good Ethernet cable is securely attached to the radio.
e
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 118 for more information.
