36 Basic Operation ODIN Intercom Matrix
IFL/F2F
The IFL/F2F section displays the IFL link status and the Frame to Frame link status. For single frame configuration, this section is
labeled IFL, the F2F label is only displayed in a multi-frame system.

IFL
The status indicators are displayed to mimic the back panel. The rows labeled with up and down triangles represent uplinks and downlinks.
The columns labeled 1 and 2 represent PRIMARY and SECONDARY.
The link is up and there is no
fault detected.
The link is up but a fault is
detected.
OR
The link is not expected to be
up, but an SFP is installed.
The link is down but is
expected to be up.
The link is not expected to be
up.
NOTE:
• IFL downlinks are expected to be up for frames 1 through n-1 (n being the number of frames) of an n
frame system. IFL uplinks are expected to be up for frames 2 to n. Uplinks in frame 1 and downlinks in
the last frame are not expected, but are acceptable.
• Because one downlink (or uplink) of the primary/secondary pair is necessary for the system to operate,
the red LED is not used for links that are expected to be up (but are not) as long as the redundant link is
up and no fault is detected. In this case, the link is shown in grey (unless an SFP is installed, in which
case the link is shown in yellow). In other words, if no SFP is installed, the link is not expected to be
used and since the redundant link is up, no error/warning is shown. If an SFP is installed, yellow is
shown since the link might be expected to be up (for redundancy).
GREEN LED YELLOW LED RED LED GREY LED
F2F
The status indicators are displayed up to two rows of four LEDs. For systems with less than eight frames, only the number of
LEDs corresponding to the number of frames are shown. The top row represents links to frames 1 through 4; the bottom row
represents links to frames 5 through 8.
For single frame systems, the F2F section is hidden.
The link to the
corresponding frame is up
The link is not up and no IP
address is defined for the
frame in the frame
mapping table.
The link is not up and the
corresponding frame has
an IP address defined in the
frame mapping table.
The link representing the
current frame is always
grey. There is never a F2F
link to itself.
