II - LED Operation
The following are iMcV-Giga-FiberLinX-II diagnostic LEDs. In this example, the
functions for a 1x9 fiber port version (SC fiber) are shown below.
NOTE
In the SFP/SFP version the LNK/ACT and FDX/COL LEDs replace EXT 1000 and
DATA 1000 for the top SFP, which does not have built-in LEDs like the RJ-45
DATA port. In addition, the copper SFP LNK/ACT LED glows green (does not
flicker).
Port LEDs
FDX/COL
:
•
Glows yellow when port is operating in Full-Duplex.
•
Blinks yellow when collisions occur on port.
LNK/ACT
:
•
Glows green when link is established on port.
•
Blinks green during data activity on port.
