Removing and Installing an RP or a Line Card
Step 2 Attach an appropriate number of velcro straps to support the network interface
cables, through the slots in the cable-management bracket:
a. Pull the small end of the velcro strap through the slot in the
cable-management bracket.
b. Insert the small end of the velcro strap into the slot in the wide end of the
velcro strap.
c. Pull the small end through the velcro strap slot to secure it to the cable-
management bracket.
Step 3 Proceeding from the left port on the line card to the right port (only 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.
Step 4 Align the interface cable with the cable-management bracket.
Step 5 Repeat Step 2 through Step 4 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 6 Secure the interface cables to the cable-management bracket by wrapping the
velcro straps around them. Do not wrap the velcro straps too tightly.
Step 7 Press the velcro strap against itself to secure it.
