Radio Reset
Use the reset function if the IP address and/or passwords are lost. Use the following steps to perform a
critical parameter reset:
1
Remove power from the radio by disconnecting the AC adapter from the power injector.
2
Hold down RESET button on the power injector while applying power.
Hold the RESET button down through the entire power cycle and monitor the DATA+POWER
left LED on the power injector. Release the RESET button only after the LED is in the steady state
(45 to 60 seconds).
3
Release the RESET button.
The following configurations are reset on the radio:
•
IP address = 10.0.0.1
•
IP mask = 255.0.0.0
•
IP gateway = 0.0.0.0
•
Administration password = password
•
User password = password
•
VLAN disabled
Radio Synchronization
The radio synchronization feature improves the performance of Exalt radios operating in the same
frequency band and that are collocated (such as in repeater and hub configurations). Radio
synchronization ties radio systems together to operate off of a common clock system, ensuring that all
radios simultaneously transmit and receive, and thus eliminating near-field interference issues and
related radio system coupling.
Synchronization Modes
Synchronization can be implemented using either one or multiple GPS sources, or using the radios
'Internal' clocking signal. The following general configurations can be accommodated:
•
GPS sync, using one GPS source (sold separately) per link. Ideal for links where the radios are not
collocated on the same rooftop or tower.
•
GPS sync, using one GPS source (sold separately) to drive timing to multiple collocated links,
using one or more sync distribution accessories (sold separately). The ideal solution for networks
that have multiple links at one location, but also have more nearby radio links that are not
collocated, including repeaters and multi-link backbones.
•
Internal sync, using one radio to synchronize another collocated link. This can be accomplished
with a simple cable and proper radio configuration, and ideal when only 2 radios are collocated.
Note:
In many cases, the system design will not be identical to the factory default
configuration, and in some cases, these differences prohibit the installation of the radio. If at
all possible, obtain a computer and configure the radio terminals using the browser-based
GUI. See
Exalt Graphical User Interface (GUI)
for details.
