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.
