Use Table 36 on page 80 if your switch has power management configured for N+1
power redundancy.
• Use Table 37 on page 80 if your switch has power management configured for N+N
power redundancy.
NOTE: If power management is configured for N+N redundancy, the
maximum fan speed is lowered, reducing the chassis’ maximum power
consumption.

200 W Switch Fabric and Routing Engine (SRE) module
200 W Second SRE module
100 W Switch Fabric module

2.
Calculate the maximum internal power consumption of the entire switch by adding
in the power requirements of each line card.
For example, for a switch fully loaded with 8-port SFP+ line cards and using N+1 power
redundancy, the maximum internal power consumption:
= (chassis watts) + 8 (8-port SFP+ line card watts)
= (1600 W + 8 (450 W))
= (1600 W + 3600 W)
= 5200 W
