Power Filler Module

Changing the DC Power Module

It is possible to change the power modules from NCS2006-DC20 to NCS2006-DC and vice-versa, without
powering down the NCS 2006 system. While changing the power modules, ensure that only one power module
is replaced at a time and the other power module continues to supply power to the shelf. However, during
regular operation of the node, the NCS 2006 shelf must have the NCS2006-DC20, NCS2006-DC, or
NCS2006-DC40 power module. See
on page 289
changing the power modules.
Power Filler Module
For redundant power supplies, two AC or DC power modules can be installed in Slot A and Slot B of the NS
2006 shelf. However, only one power module can sustain the functioning of the entire NCS 2006 system. In
that case, insert a power filler module in the empty slot.
