For example, for an MX10008 with eight MX10K-LC2101 line cards, the maximum power consumption
@400 Gigabit Ethernet mode is:
= 8* 1425 W= 11400 W
3. Add the power consumption from Step
To continue from the previous example, add the wattage from eight cards to a redundant configuration.
(11400 W) + (2650 W)
= 14050 W required

Calculating the Number of Power Supplies Required for Your MX10008 Configuration
