4.3.3.2 Carrier Activation and Carrier Information Tables
Each NPU engine is seen as a virtual AMC, with its own power and reset domain. Even though they are not
physically extractable, relevant carrier information records are present in FRU data as to insure proper
compatibility with the AMC.0 R2.0 specification.
