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.
