Troubleshooting Power Management
If one or more PIMs remain offline when you power on the chassis, the combination
of PIMs installed might exceed the power and heat capacity of the chassis. For
information about the maximum power and heat tokens permitted for each chassis,
see “Planning for Power Management” on page 72.
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-ratings CLI commands:
user@host> show chassis fpc
Temp CPU Utilization (%) Memory Utilization (%)
Slot State (C) Total Interrupt DRAM (MB) Heap Buffer
0 Online -------------------- CPU less FPC --------------------
1 Online -------------------- CPU less FPC --------------------
2 Online -------------------- CPU less FPC --------------------
3 Empty
4 Empty
5 Offline ------ Hardware exceeds High Power token limits ------
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-ratings command 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:
