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 low-power tokens, high-power tokens, and heat tokens required by each PIM, and compare them to the capacity of the chassis.

Note: The low power and high power correspond to a specific voltage for that PIM.

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:

  1. Check Table 57 to determine the token values for low-power, high-power, and heat for each PIM that you plan to install in the chassis.
  2. For all PIMs to be installed in the chassis:
    1. Add the low-power tokens for all PIMs to be installed in the chassis.
    2. Add the high-power tokens for all PIMs to be installed in the chassis.
    3. Add the heat dissipation tokens for all PIMs to be installed in the chassis.
  3. Verify that the total number of low-power tokens, total number of high-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 58.

Table 57 shows the low-power consumption, high-power consumption, and heat dissipation, represented in non-dimensional tokens, assigned to each J-series PIM and TIM.
