Provisioning Additional Power for the T1600 Routing Node
For a maximally configured T1600 routing node, we recommend that you provision
at least 64 A @ –48 VDC for each power supply input in the system.
We recommend that you provision a facility circuit breaker for each DC power supply
input rated for at least 125% of the continuous current that the input draws at
–48 VDC.
