[. . . ] An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point. · · 92 Copyright © 2010, Juniper Networks, Inc. Chapter 15: Replacing M7i Hardware Components To remove a FIC or PIC cable: 1. If the interface connects to fiber-optic cable, have ready a rubber safety cap for each cable you are removing. 2. If removing all cables connected to the interface, press and hold the PIC offline button on the FIC until its failure indicator LED lights, which usually takes about 5 seconds. The failure LED is usually red; for more information, see the M7i Multiservice Edge Router PIC Guide. 3. If the interface uses fiber-optic cable, immediately cover each transceiver and the end of each cable with a rubber safety cap. 4. Arrange the cable 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. Placing fasteners on the loop helps to maintain its shape. Installing an M7i FIC or PIC Cable 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. An arc smaller than a few inches in diameter can damage the cable and cause problems that are difficult to diagnose. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point. · · To install a PIC cable (see Figure 36 on page 94): 1. Have ready a length of the type of cable used by the interface, as specified in "FIC Specifications for the M7i Router" on page 173. 2. If the interface cable connector port is covered by a rubber safety plug, remove the plug. 3. Insert the cable connector into the cable connector port on the interface faceplate.

Secure the cable so that it is not supporting its own weight as it hangs to the floor. Verify that the FIC or PIC is functioning correctly by noting whether the normal function indicator LED is lit. The normal function indicator LED is usually green; for more information, see the M7i Multiservice Edge Router PIC Guide. You can also verify correct PIC functioning by issuing the show chassis fpc pic-status command, described in "Maintaining the M7i FIC and FIC Cables and PICs and PIC Cables" on page 70.

Removing an SFP does not interrupt PIC functioning, but the removed SFP no longer receives or transmits data. To replace an SFP, perform the following procedures: · · Removing an SFP from an M7i Router on page 95 Installing an SFP into an M7i Router on page 96 94 Copyright © 2010, Juniper Networks, Inc.
