800 WMaximum output power
Each DC power supply has a single DC input (24, –48, or –60 VDC and return) that
requires a dedicated circuit breaker. We recommend that you use a facility circuit breaker
rated for 40 A @ 24 VDC. Doing so enables you to operate the router in any configuration
without upgrading the power infrastructure, and allows the router to function at full
capacity using multiple power supplies.
