2.3 Intelligent Platform Management Controller
The Intelligent Platform Management Controller (IPMC) is derived from Artesyn's IPMC
building block and consists of two coupled micro controllers:

IPMC Master Controller (IMC) based on an Atmega 256

IPMC Slave Controller (ISC), based on an Atmega 168
2.3.1 IPMB0 Interface
IPMB0-A is connected to the I
2
C controller of the IMC, IPMB0-B to the I
2
C controller of the ISC.
Both micro controllers have their own I
2
C controller and handle message transmission and
reception independently, including bus error handling and bus arbitration.
Received messages sent to both the IMC and the ISC channels are collected by the IMC. The IMC
dispatches messages which have to be sent either to its own I
2
C interface or to the ISC for
transmission.
2.3.2 IPMC Standard Functions
The standard functionality of the Artesyn IPMC is available on the IPMC of the Centellis 2000
User Card 10GE with Telco Alarm. For detailed information, see the
Centellis 2000 User Card-
10GE: Control via IPMI Programmer’s Reference .
2.4 Power Supply
The Centellis 2000 User Card-10GE is powered by dual redundant -48 VDC to -60 VDC (rated
voltage) from the backplane connector. The IPMC is powered by a redundant 3.4 V from the
shelf manager part of the board via the backplane.
The power supply of the shelf manager is compliant with the requirements of the PICMG 3.0
R3.0 (AdvancedTCA) specification. Each of the four power connections is separately fused. Fuse
rating is 1 A.
An EMI filter at the power input ensures conducted emission levels below EN 55022 class A.
