Centellis 2000 User Card-10GE Installation and Use (6806800H33C)

2.3.1 IPMB0 Interface

IPMB0-A is connected to the I

C controller of the IMC, IPMB0-B to the I

C controller of the ISC.

Both micro controllers have their own I

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

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. 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 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 B.

2.4.1 Onboard and External Supply

The Centellis 2000 User Card-10GE has no provisions to switch off the power input. The board

is powered whenever the power is attached to the Centellis 2000 system (-40 VDC to -72 VDC).

The board satisfies the standby power limit of 10 W for AdvancedTCA FRUs. Typical power

consumption of the Centellis 2000 User Card-10GE board is 2.8 W.
