Fiber Status LEDs:
The LED status indicators on the Q-Series modules are provided as troubleshooting aides in diagnosing
and resolving technical problems so that a technician can easily assess the status of the module.
All transmitter and receiver LEDs are GREEN (with the exception of the Activity LED on the RJ45 port on
Network models) and can be in one of three states: OFF, FLASHING, or ON.
In the case of dual or redundant video modules, both return fibers are monitored by LEDs L2 and L4 (dual video)
or L2 and L2' (redundant video) and will operate the same if only one or both of these fibers is detected. LEDs
L1 and L3 are mutually-exclusive from each other with ONE exception
–
ALL LEDS FLASHING IN UNISON INDICATES THAT THE MODULE IS IN ALARM!
A module will be declared in ALARM if any of the following conditions exist:

Over the maximum temperature threshold (module or chassis)

Wrong or missing voltage

Bad firmware checksum value
LEDs Off:
NO SFP
– The SFP is missing or not seated properly in the socket
NOT LOCKED – The SFP and a signal are present but not locked to the source.
Transmitter:
RETURN PATH LOCKED
– The return signal is present and locked to the source.
FIBER ACTIVE, NO DVI 1, 2 – Valid data path but no DVI
FIBER ACTIVE, DVI 1, 2 VALID – Valid data path and valid DVI
Receiver:
FIBER ACTIVE
– A valid return signal is present
LOCKED, NO DVI 1 & 2 – Data is present, but no DVI
LOCKED, DVI 1 & 2 VALID – Data and valid DVI present
Network Status LEDs:
On the RJ45 Port:
Yellow LED Flashing = Activity
Green LED on = Link
10/100:
On when speed of link is 100 Mb/sec.
Off when speed of link is 10 Mb/sec.
FD/COL:
On when operating in Full Duplex.
Off when operating in Half Duplex.
Flashing indicates Collision. NETWORK
