Appendix A - Technical Information
A 1. Troubleshooting
This chapter provides solutions to problems that can occur during the installation and operation of the
Liberator-V1000. It covers various aspects of installation and network setup.
Note: Each of the following points must be checked at both ends of the link. Start by running the entire
procedure on one side (e.g. Terminal A). If this does not solve the problem, repeat all the steps at the opposite
terminal.
1.1. Power and Network Connection
You must verify that the terminal is connected to the power. The PoE injector must be installed and plugged
in. Go to the terminal, disconnect the RJ-45 connector and verify if there is power in the cable using a PoE
++
tester.
WARNING: It is strongly advised that the mains power supply should be disconnected before making or
breaking the CAT5e drop-cable connection between the PoE
++
supply and the radio terminal (Outdoor Unit).
If it is not possible to disconnect the mains power before making or breaking the CAT5e drop-cable
connection between PoE
++
and radio terminal, then ALWAYS first disconnect any network cable attached to
the “IN” port of the PoE
++
supply.
Take the network cable and plug it into a notebook or a network testing device and verify that there is a valid
network connection. If there is any problem, please replace the cable and validate the connection again.
1.2. Network Configuration
Check that the PC’s IP address is in the same range and subnet as the Liberator-V1000.
Note: The default IP address of the Liberator-V1000 is 192.168.0.21 and 192.168.0.22 for terminal A and B
respectively. All terminals on the network must have a unique IP address in the same range, e.g. 192.168.0.X.
Any terminal with identical IP addresses will not be visible on the network. They must all also have the same
subnet mask (e.g. 255.255.255.0).
Ping the terminal to make sure that the Liberator-V1000 is responding. On a Windows PC, go to Start → Run
→ Type “Command” → Type “ping 192.168.0.21/22”. A successful ping will generate four replies. As soon as
the network configuration is correct you can access the GUI (Graphical User Interface) and check the settings
according to the section titled “Factory-Defaulting a Terminal”.
If a Management VLAN is enabled, then it will be necessary to set-up the communicating PC / laptop /
network device with the same VLAN ID, in order to communicate with the V1000 management agent.
1.3. Misalignment
On the Installation screen you see the signal strength in dBm (e.g. -30 dBm). The correct RSSI value can be
obtained from the Sub10 Systems Link Availability Calculator. If the value is more than 5dB below below the
Link Availability Calculator value, then the antenna is not properly aligned to receive the signal. You therefore
need to re-align the terminal to its opposite terminal (please follow the instructions in the section titled
“Antenna Alignment”).
1.4. Mixed radio terminals
It is not possible to mix Single-port and Dual-port terminals.
1.5. Encryption settings
If AES encryption is used, then it must be enabled on both ends of the link, and the same encryption key used
on both ends, or else no data will pass over the link.
