The following table lists the link status values for the Fibre Channel LEDs.

Green LED Amber LED Meaning
Off Off One of the following situations is in
effect:
v The port is not configured in flex
hardware.
v The port is not active in the current
profile. For example, in a 2 x 16 Gb
profile, 2 ports are inactive.
Off On The port is configured, but the link is
not detected at the transport layer. This
situation is the result of the port not
being connected or of a failed link
negotiation with the switch.
On Off The link is up and running at the
expected port speed. This display does
not necessarily imply logical
connectivity, that is, completion of
FLOGI or FIP.
On On The link is up, but running at a
degraded speed.
SAS port LEDs
LEDs on the rear of the SAN Volume Controller 2145-SV1 node indicate the status
of the SAS port.
The SAN Volume Controller 2145-SV1 uses two rows of LEDs on the optional 12
Gbps SAS adapter to show the status of the SAS port. The LEDs are arranged in
the same order as the ports. Those four ports are immediately to the right of the
LEDs and are numbered from left to right. The following figure shows the location
of the LEDs.
