DLC103 Front Panel LEDs
LED Function Color Description
OK
Module
Status
OFF If power is applied to the system, an internal fault with the DLC103 may exist.
n Green Normal operation.
n Yellow If the RX LED is not flashing yellow, then a temperature alarm is indicated.
n Red
The TX or RX LEDs may indicate the cause of the alarm or the alarm condition can indicate an internal
error. 1
EMS
DigiLink Manager
System
Status
OFF
The DLC103 module is in local mode and its configuration is controlled by the onboard
configuration switches.
n Green
The DLC103 module is in remote mode and the configuration has been set by the DigiLink Manager
EMS. When in remote mode, the actual configuration of the module will likely not match the settings
of the configuration switches and changing the configuration switches will have no effect on the
module’s operation.
TX
SD
270Mb/s SDI, ASI
(and 2.97Gb/s)
Status
OFF SDI/ASI signal is not detected (also 3G signal not detected).
n Green SD/ASI signal is detected (or 3G signal detected when HD LED is also Green).
n Red 3G signal is detected, but blocked (when TX HD LED is also Red). 2
HD
1.485 Gb/s SDI
(and 2.97Gb/s)
Status
OFF HD signal is not detected (also 3G signal not detected).
n Green HD signal is detected (or 3G signal detected when TX SD LED is also Green).
n Red 3G signal is detected, but blocked (when TX SD LED is also Red). 2
TX
Transmitter
Status
OFF Receiver mode is selected.
n Green
Normal TX operation (input signal is present). An unknown rate is indicated if the TX SD and TX HD
LEDs are off.
n Yellow Standby operation (no input signal).
 Red No SFP is installed or an SFP failure exists. 3
RPTR Repeater Status
OFF Repeater mode is not selected.
n Green Repeater mode is selected.
RX Receiver Status
OFF Transmitter mode is selected.
n Green
Normal RX operations (input signal is present). An unknown rate is indicated if the RX SD and RX HD
LEDs are off.
n Yellow Standby signal is detected.
 Yellow Receive optical power is high.
 Red Low light, loss of SFP RX signal, or an SFP failure exists. 3
RX
SD
270Mb/s SDI, ASI
(and 2.97Gb/s)
Status
OFF SDI/ASI signal is not detected (also 3G signal not detected).
n Green SD/ASI signal is detected (or 3G signal detected when HD LED is also Green).
n Red 3G signal is detected, but blocked (when RX HD LED is also Red). 2
HD
1.485 Gb/s SDI
(and 2.97Gb/s)
Status
OFF HD signal is not detected (also 3G signal not detected).
n Green HD signal is detected (or 3G signal detected when RX SD LED is also Green).
n Red 3G signal is detected, but blocked (when RX SD LED is also Red). 2
1. Red OK LED can also indicate loss of video when the Video Loss Alarm is enabled.
2. A 3G input signal is blocked when a non-3G SFP is installed or when SW3:S1 (TX 3G) or SW3:S2 (RX 3G) is set to OFF.
3. TX and RX LEDs flashing red together indicates that no SFP is installed or that an unsupported SFP is installed (for example, a non-video DWDM SFP).
