DC Power Circuit Breaker Requirements for the MX480 Router

Each DC power supply has a single DC input (–48 VDC and return) that requires a
dedicated circuit breaker. If you plan to operate a maximally configured DC-powered
router with normal-capacity power supplies, we recommend that you use a dedicated
