The following table lists power specifications for the NCS 2015 shelf.
Table 28: Cisco NCS 2015 Power Specifications
Power Redundancy (N+N)
Up to four power modules can be installed. This allows support
for 1+0, 1+1, 2+0, and 2+2 power redundancy.
AC
Up to four power modules can be installed. This allows support
for 3+1, 2+2, 2+1, and 1+1 power redundancy and A and B battery
plant dual feeds redundancy.
