Front Panel Operation
Name
Used to easily remove and replace the chassis into the user-provided rack
enclosure.
Used to turn power ON/OFF the unit.
For units as equipped, a prime power switch is mounted behind the front
panel.
To access the switch, loosen the three front panel thumb screws, slide the
front panel out from the chassis, and then drop down the panel.
Before turning on power to the unit, check to make sure that installation is
complete, and verify that the LBC-4000 is connected to the proper prime
power source, RF Input, and RF Output.
Turn the switch ON and verify the cooling fan is operational, the LED
indicators illuminate as expected, and the VFD is readable.
The operational state of the LBC‐4000 is represented by two sets of five
front panel Light-Emitting Diode (LED) indicators – one set each for
'CONV A' and 'CONV B'. Each set of LEDs convey operational states as
follows:
Sum Fault: Lights RED when a fault condition has been logged and
stored.
Mute: Lights AMBER when the unit is in Mute Mode.
Online: Lights GREEN when the unit is online and carrying traffic.
Up: Lights GREEN when the module is operating as an Up Converter.
Down: Lights GREEN when the module is operating as a Down
Converter.
An active display showing two lines of 24 characters each. It produces a
blue light with adjustable brightness. Nested menus display all available
options and prompt you to carry out a required action.
Comprised of six keyswitches behind a flat membrane. The keys have a
positive 'click' action that provides tactile feedback. Enter data via the
keypad. Data, prompts, and messages are displayed on the VFD.
