4.
If the connector at the other end of the fiber-optic cable is covered by a rubber safety
cap, remove the cap. Save the cap.
5.
Remove the rubber safety cap from the QSFP+ optical transceiver on the 16-port
QSFP+ front card on the QFX3008-I Interconnect device. Save the cap.
6.
Insert the cable connector into the optical transceiver.
7.
Secure the cables so that they are not supporting their own weight. Place excess cable
out of the way in a neatly coiled loop. Placing fasteners on a loop helps cables maintain
their shape.
CAUTION: Do not bend fiber-optic cables beyond their minimum bend
radius. Bending the cables beyond their minimum bend radius can damage
the cables and cause problems that are difficult to diagnose.
Do not let fiber-optic cables hang free from the connector. Do not allow
fastened loops of cables to dangle, which stresses the cables at the
fastening point.
