DC Power Circuit Breaker Requirements for the MX80 Router
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 25 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.
If you plan to operate a DC-powered router at less than the maximum configuration and do not provision a 25 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 percent of the continuous current that the system draws at –48 VDC.
