Small form-factor pluggables (SFPs) are transceivers that can be removed from a PIC
(for more information, see "M10i PICs Description" on page 8).
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.

WARNING: Do not look directly into a fiber-optic transceiver or into the ends
of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable connected
to a transceiver 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 45 on page 119):
Place an electrostatic bag or antistatic mat on a flat, stable surface.

the strap to one of the ESD points on the chassis.
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.
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
