LED Indicators
The following table describes the status LEDs of the 140 NRP 954 01C module:
LED
Color
State
Indication
Ready
Green
OFF
The module is unpowered or the internal logic is out of order.
ON
The module is powered and the internal logic is available.
ComAct
Green
OFF
No activity on the coaxial cable.
ON
Activity is detected on the coaxial cable.
FPort1
Green
OFF
No activity on the optical fiber port 1 reception.
ON
Activity is detected on the fiber port 1 reception.
FPort2
Green
OFF
No activity on the optical fiber port 2 reception.
ON
Activity is detected on the fiber port 2 reception.
Fault
Red
OFF
No error (internal or external) detected.
ON
An error (internal or external) has been detected.
Error
Red
OFF
No internal error detected.
ON
An internal error has been detected.
BrkF
Red
OFF
Activity is detected on both optical port inputs OR no activity has ever been detected on any optical port input.
ON
One of the optical fiber port input is inactive (see FPort• LED OFF) while activity is detected or has been detected on the other optical port input (see FPort• LED ON).
Diagnostic Relay Behavior
The contacts of the relay are open whenever an error is detected (internal or external), and the Fault LED is ON. In fact the status of the diagnostic relay provides an electric information when the Fault LED status provides a visual status when an error is detected (internal or external).
Futhermore when the contacts of the diagnostic relay are open,
NOTE: When the 140 NRP 954 01C is not powered, the contacts of the diagnostic relay are open.
