AT-SBx31GC40
Line Card
The AT-SBx31GC40 Line Card has two LEDs for each slot. The LEDS,
which display link and activity information, are located between the slots,
in sets of four. The first and third LEDs of each set are for the bottom slot
and the second and fourth LEDs are for the top slot, as shown in
Figure 25.

When a slot contains a CSFP transceiver, both slot LEDS are active. Each
LED displays link and activity status information for its respective BiDi
connector on a transceiver. As an example, if the first top and bottom slots
of the line card contain CSFP transceivers, the first LED between the slots
displays link and activity status for port 1, which is the left-hand fiber
connector on the bottom transceiver. The second LED displays the same
information for port 0, the left-hand fiber connector on the top transceiver.
The third and fourth LEDs display the same information for ports 3 and 2,
the right-hand connectors on the bottom and top transceivers,
respectively. See Figure 26.
