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 110.
