Replacing PIM Cables

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

• Removing PIM Cables
• Installing PIM Cables

Removing PIM Cables

To remove a PIM cable:

1. If you are removing all cables connected to the PIM, issue the following CLI command to take the PIM offline:
   
   

   user@host> request chassis fpc slot  pim-slot offline

   For example, to take the PIM in slot 4 offline, enter the following command:

   
   

   user@host> request chassis fpc slot 4 offline

   For more information about the command, see the JUNOS System Basics and Services Command Reference.

2. Unplug the cable from the cable connector port.
3. Detach the cable from the destination port.

Installing PIM Cables

To install a PIM cable:

1. Have ready a length of the type of cable used by the PIM. For cable specifications, see Network Cable Specifications and Connector Pinouts.
2. Insert the cable connector into the cable connector port on the PIM faceplate.
3. Arrange the cable as necessary 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.
   • Place excess cable out of the way in a neatly coiled loop.
   • Use fasteners to maintain the shape of cable loops.
4. Insert the other end of the cable into the destination port.
5. Repeat the previous steps for any additional cables.
6. If the PIM is offline (its status LED is steadily red), issue the following CLI command to bring the PIM online:
   
   

   user@host> request chassis fpc slot pim-slot online

   For example, to bring the PIM in slot 4 online, enter the following command:

   
   

   user@host> request chassis fpc slot 4 online

   For more information about the command, see the JUNOS System Basics and Services Command Reference.

7. Verify that the PIM status LED shines steadily green to confirm that the PIM is online.

   You can also verify correct PIM functioning by issuing the show chassis fpc pic-status command described in the JUNOS Software Interfaces and Routing Configuration Guide.

   Note: In the show chassis fpc pic-status command, the PIM slot number is reported as an FPC number and the PIM number (always 0) is reported as a PIC number. For more information about interface naming, see the JUNOS Software Interfaces and Routing Configuration Guide.
