As an exception, there are some new network elements that employ high DC current demands
that when collectively configured in a packaged bay arrangement may exceed available fuse
position capacities found at the BDFB. In a method to utilize the existing AT&T - DC distribution
architecture, these individual network elements may be independently and directly fused at the
BDFB via an SPDU. In these instances, direct feeds to the BDFB may be considered
appropriate. However, the individual network element shall include an on/off /power cut off to
locally disconnect the power from the bay components. In applications where a bay mounted
SPDU is desired, AT&T has approved products designed to serve in that capacity and still allow
for independently fused services. Standards
