CAUTION:
inserting or removing cable. The safety cap keeps the port clean and prevents
accidental exposure to laser light.
6. 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.
CAUTION:
allow fastened loops of cable to dangle, which stresses the cable at the fastening
point.
CAUTION:
An arc smaller than a few inches in diameter can damage the cable and cause
problems that are difficult to diagnose.
7. Verify that any status LEDs on the line card faceplate indicate that the CFP is functioning correctly.
For more information about the line card LEDs, see the MX Series 5G Universal Routing Platform Interface
Module Reference. You can also verify line card functioning by issuing the show chassis fpc pic-status
command.
