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 whole 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
(1 to 3 minutes, depending on firmware installed).
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
A flashing left DATA+POWER LED on the power injector indicates that alarm conditions exist on the
radio. To access summary alarm information during normal operation, press and hold the RESET
button. The following is status for the left the DATA+POWER LED while holding the RESET:
•
Solid on is a link alarm (link is down or errored)
•
Flashing indicates a minor alarm (does not affect traffic)
Power
The radio requires a DC power source within specifications. DC can be provided from a DC battery
source, central lab/rack supply, or from the supplied AC adapter.
Terminating the RF Connectors (rc models)
Before applying power, the RF connectors must be properly terminated into a 50-Ohm load. If this is
not performed, the radio may be damaged by simply applying power. Also, there are human safety
factors to consider regarding potentially harmful RF radiation.
The following lists a few simple ways to achieve proper termination:
•
Connect a 50-Ohm coaxial termination device to the RF port of the radio. The termination must be
rated to 1W (or more). Example(s) include:
–
Broadwave Technologies P/N 552-200-002, or similar
•
Connect the complete transmission system. That is, the RF cabling including the antenna. The
cabled antenna provides a proper termination for the RF output.
•
Connect a fixed (or a series of fixed) 50-Ohm attenuator(s) to the RF connector, either directly or
at the end of an RF transmission line. The attenuator must be at least 30dB as specified at the
operating frequency and rated for a minimum of 1W input power. Examples include:
–
Broadwave Technologies P/N 352-103-xxx
