Calculating Power Requirements for MX240 Routers on page 156
Each DC power supply has a single DC input (–48 VDC and return) that requires a
dedicated circuit breaker. We recommend that you use a dedicated customer site circuit
breaker rated for 40 A (–48 VDC) minimum, or as required by local code. Doing so enables
you to operate the router in any configuration without upgrading the power infrastructure.
For high-capacity power supplies, we recommend that you use a dedicated customer
site circuit breaker rated for 60 A or 70A, or as required by local code,depending on the
input switch setting.
If you plan to operate a DC-powered router at less than the maximum configuration and
do not provision a 40 A (–48 VDC) circuit breaker, we recommend that you provision a
dedicated customer site circuit breaker for each DC power supply rated for at least 125%
of the continuous current that the system draws at –48 VDC.
