How to Calculate the Number of Power Supplies Required for Your MX10004
Conguraon
The minimum power conguraon for MX10004 routers is three power supplies. However, using the
calculated minimum power conguraon doesn’t prevent the system from triggering a power alarm. To
ensure that you don’t trigger power alarms with a fully loaded chassis, you must congure your router
for dual feed and high-power sengs.
To calculate the number of power supplies required for your minimum router conguraon:
1. Determine the power available from the power supplies. The power supplies have a set of three DIP
switches on the faceplate. These switches enable you to congure the power supply for either the
high-power (30 A) or low-power (20 A) input mode. Table 35 on page 92 and Table 36 on page 93
shows the power available for the installed power supplies.
