Hardware Management
Overview
On IXB2850 boards, the Board Management Controller (BMC) manages and monitors
the baseboard and extension card hardware components. Management tasks include:
Power Management
The BMC is the first component of an IXB2850 board to start operating after power is
applied to the board (that is, after the board is inserted into a working chassis or after
chassis power is switched on). The BMC controls the application of power to all other
components on the IXB2850 board, that is, the components are reset initially until the
BMC switches them on. However, the decision to switch power on is made by the
chassis Shelf Management Controller (ShMC).
Just after board power-on, the BMC establishes a connection with the ShMC over the
Intelligent Platform Management Bus (IPMB) on the backplane. After providing the
ShMC with information about the board hardware, the BMC enables power for the
entire board on request from the ShMC. Next, the BMC releases the reset signal for the
Network Processor (NP). A detailed description of the board boot sequence can be
found in
The IXB2850 board can also operate in a chassis that is not AdvancedTCA* compliant,
where the ShMC is not present. To make this possible, there is a dedicated hardware
jumper on the baseboard that determines whether the BMC should communicate with
the ShMC. See
The BMC is also responsible for monitoring output voltage and current from the power
supplies and can provide this information to the ShMC and NP.
