Each DC power supply has a single DC input (–48 VDC and return) that requires a
dedicated facility circuit breaker. We recommend that you use a customer site circuit
breaker rated for 40 A (–48 VDC) minimum for each DC power supply, or as required by
local code. Doing so enables you to operate the services gateway in any configuration
without upgrading the power infrastructure.
If you plan to operate a DC-powered services gateway at less than the maximum
configuration and do not provision a 40 A (–48 VDC) circuit breaker, we recommend
that you provision a circuit breaker for each DC power supply rated for at least 125% of
the continuous current that the system draws at –48 VDC, or as required by local code.
