Calculating the Power Consumption of Your MX10008 Configuration
Use the following procedure to determine the maximum power you need to supply to the router. To
calculate maximum system power consumption, you first determine the combined maximum internal power
requirements of all the router components and then divide this result by the power supply output power.
To calculate maximum system power consumption:
1. Determine the maximum power consumption of the base chassis components (that is, the components
other than the line cards). Use Table 31 on page 101 if your router is configured as either the standard
base or redundant configuration.
Table 31: Chassis Power Consumption for Standard Configurations
Redundant Configuration Base Configuration Chassis Component
1100 W 1100 W Fan tray, JNP10008-FAN
1212 W 1212 W Fan tray, JNP10008-FAN2
350 W/330 W 175 W/165 W Routing and Control board (128G/64G) @40°
C
1200 W 1000 W Switch fabric board (SFB)
2. Calculate the maximum internal power consumption of the entire router by adding in the power
requirements of each line card. See Table 32 on page 101 for a chart of the power needed for line cards.
