Chapter 11: Troubleshooting Hardware Components

To bring the PIM online:

1.Check if the PIM exceeds the power and heat tokens permitted by issuing the show chassis fpc and show chassis power-ratingsCLI commands:

user@host> show chassis fpc

In this example, J-series power management has placed the PIM in slot 5 in an offline state to prevent damage. If brought online, the PIM would cause the combination of PIMs to exceed the maximum limit of 83 high-power tokens for the J2350 router.

NOTE: In the show chassis power-ratingscommand output, the PIM slot number is reported as an FPC number.

The offline PIM is not powered off and continues to draw minimal power.

2.To bring the PIM online, you have the following options:

Remove one or more PIMs from the chassis. This option requires that you power off the router. For more information about removing PIMs, see “Removing a PIM” on page 172

Bring the PIM online without powering off the router. To do so, use the set chassis fpc offline command to set another PIM slot in the chassis to the offline state. For example:
