DC Power Module

DC Power Module
The NCS 2015 system is powered by DC power modules with 3+1, 2+2, 2+1, and 1+1 redundancy. The
supported DC power module on the NCS 2015 shelf is NCS4K-DC-PSU-V1. The DC power module draws
power from the power plant to turn on the NCS 2015 shelf.
The PWR-CON-LMT alarm is raised in the Alarms tab in CTC when the installation or pre-provisioning of
a card causes the power consumption to exceed the power limit.
The PWR-CON-LMT alarm is raised on the NCS2015 shelf when the power consumption of the shelf exceeds
the maximum power limit. A database backup is performed on the shelf. Additional power modules are
installed to increase the power limit. A database restore is then performed on the shelf. The PWR-CON-LMT
alarm still persists even though the power consumption is within the power limit.
Note The total power consumption of the shelf is calculated by the controller card and displayed in CTC in the
Provisioning > Power Monitor tab.

Power Filler Module

For redundant power supplies, four AC or DC power modules can be installed in the NCS 2015 shelf. However,
only one power module can sustain the functioning of the entire NCS 2015 system. You can install power
filler modules in the empty slots.
