2. Connect and route the fiber-optic cables; see Figure 4-26:
a. If it is not already open, grasp the handle at the center of the cable tray and press the latch just behind
it to open the front panel of the cable tray.
b. Insert each cable into the appropriate connector on the card.
c. Starting with the cards installed in the inner slots (4 to 7 and 8 to 11), insert the cables for a card
between the cable guides for that card in the outer partition.
d. Slide the cables under the slotted cover of the inner partition as much as is possible, but do not allow
the cables to have a bend radius of more than 1.25 inches (3.18 cm).
e. Tie-wrap the bundled cables from each card to the outside edge of the rack.
f. Continue routing all fiber-optic cables, working toward the outer slots (1 to 3 and 12 to 14).

Caution Risk of damage to fiber-optic cables. Fiber-optic cables are fragile and are easily damaged
when bent. To reduce the risk, never step on a cable; never twist it when connecting it to or
disconnecting it from an traffic card.
