Figure 20: AMC Connector Port Distribution
Refer to the AMC.0 specifications for more information on AMC pin distribution. The 170 pins are
distributed among the following groups:

Fabric interfaces

AMC clock interfaces

JTAG interfaces

System management interfaces

Payload power interfaces

Logic ground contacts
8.4.6 Management Functions
The AMC specifications describe the module management using the Intelligent Platform Management
Interface (IPMI) and Electronic Keying (E-Keying).
The E-Keying is a mechanism of detecting a module and enabling the interfaces that are compatible with
the MicroTCA carrier and prevent collision of incompatible interfaces. The E-keying is implemented in the
Carrier Manager and allows only compatible interfaces to be enabled in each module. Each AMC module
contains a Management Module Controller (MMC) that provides the required interfaces to support IPMI
and E-Keying.
The IPMI and E-Keying were initially designed for the Telecommunication networks using the ATCA
systems. These features enable the MicroTCA applications to utilize dynamic configuration and alerts
users when a conflict is detected.
