Small form-factor pluggables (SFPs) are optical transceivers that can be removed from
a PIC (for more information, see
SFPs are hot-insertable and hot-removable. Removing an SFP does not interrupt PIC
functioning, but the removed SFP no longer receives or transmits data. To replace an
SFP, perform the following procedures:

Installing an SFP into an M7i Router on page 167
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:
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 remove an SFP (see Figure 60 on page
Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the
1.
SFP. Have ready a rubber safety cap for the SFP transceiver and the cable.
Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
2.
ESD points on the chassis.
