2040RDA-FR/16FR — Instruction Manual 23
Power Up
A red FAULT LED indicates an error situation and, when noted with the
other indicator LEDs, can indicate a specific problem area.
Table 1 describes
signal output and LED indications for the various input combinations and
user settings.
Table 2 gives the reclock rates reported by the sequence of the three MODE
LEDs on the front of the module. This information is also silkscreened on
the circuit board. The LED on/off states reflect the auto-reclocking signal
rate detected by module or the reclock rate manually selected on web page.
Table 1. Indicator LEDs and Conditions Indicated
LED Indication Condition
FAULT
(red)
Off Normal operation.
On continuously
Module has detected an Optic 1 or Optic 2 internal fault from the submodule or a write failure
has occurred on the front module.
Long flash
No input is detected for the input or the input does not match the format selected manually, no
rear module is present, or the wrong rear module is present.
COMM
(yellow)
Off No activity on frame communication bus.
3 Short Flashes Location Command received by the module from a remote control system.
Short flash Activity present on the frame communication bus.
PWR
(green)
Off No power to module, fuse blown, or module’s DC/DC converter failed.
On continuously Normal operation, module is powered.
REM OVR
(yellow)
On Remote control is overriding on-board jumper settings.
Off Module is operating according to on-board jumper settings.
CD
(green)
On Carrier is detected for the selected input to the module.
Off No carrier is detected for the selected input to the module or input signal is missing.
LD
(green)
On
Selected input carrier is locked to a valid frequency for the module (143M, 177M, 270M,
360M, 540M, or 1485M).
Off Module is in bypass mode or not locking to valid frequency or input signal is missing.
MODE
(yellow)
1
1 These LEDs are green on some earlier modules.
See Table 2
LED On/Off states indicate auto-reclocking signal rate detected by module or reclock rate man-
ually selected on web page.
SFP_INST
(yellow)
On Indicates SFP submodule option installed in rear module.
Off Indicates no SFP submodule option installed in rear module.
