Installing an SFP in an M40e PIC

To install a replacement SFP (see Figure 116 on page 211):
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
1.
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.
2.
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 are installed vertically in the chassis, and faces upward on platforms
in which FPCs are installed horizontally in the chassis.
Slide the SFP into the slot. If there is resistance, remove the SFP and flip it so that the

connector faces the other direction.
Remove the rubber safety cap from the transceiver and the end of the cable, and
5.
insert the cable into the transceiver.
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: 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.
Arrange the cable in the cable management system to prevent the cable 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.
CAUTION: 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.
