Installing an M7i PIC
WARNING: Do not look directly intotransceivers 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 loopsofcable todangle, which stresses the cableat the fastening
point.
To install a PIC (see Figure 58 on page 162):
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. Verify that the router is attached to
a proper earth ground.
2. If the PIC uses fiber-optic cable, verify that there is a rubber safety cap over each
transceiver on the faceplate. Install a cap if necessary.
