Front-Panel Description
100Base-FX Port Status LEDs
These LEDs display information about the individual ports. See
Dual-Purpose Port LEDs
shows the LEDs on a dual-purpose port. You can configure each port as either a 10/100/1000
port through the RJ-45 connector or as an SFP module, but not both at the same time. The LEDs show
how the port is being used (Ethernet or SFP module).
The LED colors have the same meanings as described in

Dual-Purpose Port LEDs
Alternating
green-amber
Link fault. Error frames can affect connectivity, and errors
such as excessive collisions, CRC errors, and alignment and
jabber errors are monitored for a link-fault indication.
Solid amber
Port is not forwarding. Port was disabled by management, an
address violation, or STP.
Note
After a port is reconfigured, the port LED can remain
amber for up to 30 seconds while STP checks the
switch for possible loops.
