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 install a replacement SFP (see Figure 38 on page 97):
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect

the strap to one of the ESD points on the chassis.
Verify that a rubber safety cap covers the SFP transceiver, installing one if necessary.

Orient the SFP over the port in the PIC so that the connector end will enter the slot

first and the SFP connector faces the appropriate direction:
If the PIC has ten SFP ports, the ports are arranged in two columns. The SFP
connector faces to the right for ports in the left column, and to the left for ports in
the right column.
If the PIC has one or two SFP ports, the SFP connector faces to the left on platforms
in which FPCs install vertically in the chassis, and faces upward on platforms in
which FPCs install horizontally in the chassis.
