VOLUME II, CHAPTER 1, SYSTEM OVERVIEW
Power Supply Protection
l Protection is hitless for an NCC power supply failure. If the NCC converter or
one of its supply rails fails, the NPC will take over without interruption. And
vice versa.
l With an NPC installed, the NCC can be withdrawn and replaced without
further impacting traffic.
l For 24 Vdc operation two PCCs are required for platform protection, one each
for the NCC and NPC.
