Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the
SFP. Have ready a rubber safety cap for the SFP transceiver and the cable.

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
connect the strap to one of the ESD points on the chassis. Make sure the router
is attached to a proper earth ground. For more information about ESD, see

Label the cable connected to the SFP so that you can later reconnect it to the
correct SFP.

Disconnect the cable from the SFP. Immediately cover the transceiver and the
end of the cable with a rubber safety cap.

5.
Arrange the cable in the cable management system to prevent it 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.

Pull the ejector handle away from the SFP faceplate to unseat the SFP from the
PIC. Pull the SFP out of the PIC and place it on the antistatic mat or in the

WARNING: Do not look directly into transceivers or into the ends of fiber-optic cables
connected to a transceiver. Fiber-optic transceivers emit laser light that can damage
your eyes.

CAUTION: When handling fiber-optic transceivers and fiber-optic cable, observe the
following precautions:
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.
