2.Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. For more information about ESD, see “Prevent Electrostatic Discharge Damage” on page 134.

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

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

Do not look directly into the ends of fiber-optic cables or into the transceivers on the interface faceplate. Single-mode fiber-optic cable and the interfaces that use it (such as ATM and SONET/SDH interfaces) emit laser light that can damage your eyes.

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.

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.

Avoid bending 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.

6.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 electrostatic bag.

Install an SFP

To install a replacement SFP, follow this procedure (see Figure 33):

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. For more information about ESD, see “Prevent Electrostatic Discharge Damage” on page 134.
