Step 6 Proceeding from the left port on the line card to the right port (on line cards with
multiple ports), identify the network interface cable for the line card port and
insert the cable connector into the line card port (see
Figure 5-21 ).
a. Align the interface cable with the cable-management bracket.
b. Repeat for the remainder of the interface cables for this line card.
Note Carefully adjust the interface cables in the cable-management bracket to
prevent any kinks or sharp bends in the interface cables. Kinks and sharp
bends can destroy or degrade the ability of the optical fiber to propagate
the signal-encoded beam of light accurately from one end of the cable to
the other. Also, allow adequate strain relief in the interface cables.
Step 7 Secure the interface cables to the cable-management bracket by wrapping the
velcro straps around them (see
Figure 5-21 ).
