Planning for Power Management
Before you install a chassis or add a new PIM to an existing
chassis, verify that the combination of PIMs and modules (PIMs or
PIMs plus a WXC Integrated Services Module) 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 modules in a single chassis
that exceeds the maximum power and heat capacity of the chassis. If
J-series power management is enabled, PIMs and modules (PIMs or PIMs
plus a WXC Integrated Services Module) 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 37 to determine the token values for low-power, high-power,
and heat for each PIM that you plan to install in the chassis.
- For all PIMs to be installed in the chassis:
- Add the low-power tokens for all PIMs to be installed
in the chassis.
- Add the high-power tokens for all PIMs to be installed
in the chassis.
- Add the heat dissipation tokens for all PIMs to be installed
in the chassis.
- 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 38.
Table 37 shows the
low-power consumption, high-power consumption, and heat dissipation,
represented in non-dimensional tokens, assigned to each J-series PIM.
