Replace PIC Cables

Removing and installing PIC cables does not affect router function, except that a PIC does not receive or transmit data while its cable is disconnected. To replace a PIC cable, perform the following procedures:

Removing a PIC Cable

To remove a PIC cable, follow this procedure:

1.If the PIC connects to fiber-optic cable, have ready a rubber safety cap for each cable and transceiver.

2.If removing all cables connected to the PIC, use one of the following methods to take the PIC offline:

Press and hold the PIC offline button until its failure indicator LED lights, which usually takes about 5 seconds. The failure LED is usually red; for more information, see the M160 Internet Router PIC Guide. For the PICs that install on an FPC1, the offline button for each PIC is next to it on the FPC card carrier. For the PICs that install on an FPC2, the offline button is on the PIC faceplate. See Figure 6.

Issue the following CLI command:

user@host>request chassis pic fpc-slot fpc-slotpic-slot pic-slot

offline

For more information about the command, see the JUNOS Protocols, Class of

Service, and System Basics Command Reference.

3.Unplug the cable from the cable connector port. If the PIC uses fiber-optic cable, immediately cover each transceiver and the end of each cable with a rubber safety cap.

WARNING: Do not look directly into the ends of fiber-optic cables or into the transceivers on the interface faceplate. Single-mode fiber-optic cable and the interfaces that use it (such as ATM and SONET/SDH interfaces) emit laser light that can damage your eyes.
