When handling fiber-optic transceivers and fiber-optic cable, observe the
following precautions:
•
Do not leave a fiber-optic transceiver uncovered except when inserting or
removing cable. The safety cap keeps the port clean and prevents
accidental exposure to laser light.
•
Do not bend fiber-optic cable beyond its minimum bend radius. An arc
smaller than a few inches in diameter can damage the cable and cause
problems that are difficult to diagnose.
•
Do not let fiber-optic cable hang free from the connector. Do not allow
fastened loops of cable to dangle, which stresses the cable at the fastening
point.

To install an SFP transceiver in the LN1000 RTM:
1.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to one of the ESD points on the chassis.
2.
Verify that a rubber safety cap covers the SFP transceiver, installing one if necessary.
3.
Orient the SFP over the port in the RTM so that the connector end will enter the slot
first and the SFP connector faces the appropriate direction:
4.
Slide the SFP into the slot. If there is resistance, remove the SFP and flip it so that the
connector faces the other direction.
5.
Remove the rubber safety cap from the transceiver and the end of the cable, and
insert the cable into the transceiver.
6.
Arrange the cable in the cable management system to prevent the cable from
dislodging or developing stress points. Secure the cable so that it is not supporting its
own weight as it hangs to the floor. Place excess cable out of the way in a neatly coiled
loop in the cable management system. Placing fasteners on the loop helps to maintain
its shape.
7.
Verify that the SFP is installed by entering the CLI
show chassis hardware detail
command. Output will display as follows:
