NOTE: Power cords and cables must not block access to router components or drape
where people might trip on them.
For information about the DC power supply, see “J2320 and J2350 Services Router
Hardware Features” on page 13 and “J4350 and J6350 Services Router Hardware
Features” on page 26.
To connect the DC power cable during initial installation, see “Connecting DC
Power” on page 126.
To replace a DC power cable, see “Replacing DC Power Supply Cables” on page 194.
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 on page 113 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:
a. Add the low-power tokens for all PIMs to be installed in the chassis.
b. Add the high-power tokens for all PIMs to be installed in the chassis.
c. 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 on page 114.
Table 57 on page 113 shows the low-power consumption, high-power consumption,
and heat dissipation, represented in non-dimensional tokens, assigned to each J-series
PIM and TIM.
