Planning for Power Management
Before you install a chassis or add a new PIM to an existing
chassis, verify that the combination of PIMs to be installed does
not exceed the power and heat capacities for that model. Add the power
and heat tokens required by each PIM, and compare them to the capacity
of the chassis.
 |
Caution: Do not install a combination of PIMs in a single chassis that
exceeds the maximum power and heat capacity of the chassis. If J-series
power management is enabled, PIMs that exceed the maximum power and
heat capacity remain offline when the chassis is powered on.
|
To verify that the combination of PIMs to be installed in a
chassis does not exceed the power and heat capacities for that model:
- Check Table 51 to determine the token values for power and heat for each
PIM that you plan to install in the chassis.
- Add the power tokens and heat dissipation tokens
for all PIM to be installed in the chassis.
- Verify that the total number of power tokens and
the total number of heat dissipation tokens do not exceed the maximums
permitted for your J-series chassis as specified in Table 52.
Table 51 shows the
power consumption and heat dissipation, represented in non-dimensional
tokens, assigned to each J-series PIM.
