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.
5. Before connecting the cable, verify the position of the handle on the
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 98, or the down
position if the transceiver is in the bottom row.
