SBx81GS24a Line Card
Note
The dust cover protects the fiber optic port on the SFP transceiver
from dust contamination. It should not be removed until you are
ready to connect the fiber optic cable.
6. Before connecting the cable, verify the position of the handle on the
SFP transceiver. The handle should be in the up position if the
transceiver is in the top row on the line card, as shown in Figure 86, or
the down position if the transceiver is in the bottom row.
