Boot Sequence
The IXB2850 boot sequence is shown in
operating after board power on are the Board Management Controller (BMC) and early
power I
extension boards, such as the Quad Gigabit Ethernet Mezzanine Card and the Fabric
Interface Card (FIC). The BMC establishes communication with the chassis's Shelf
Management Controllers (ShMCs) to provide each ShMC with information about the
type and configuration of the board. The ShMC decides whether this board can operate
in a particular slot of chassis and allow the BMC to switch on the power for the
remaining components of the board. When power is switched on, the BMC releases an
NPU reset signal.
The NPU starts execution of the Initial Loader code and controls the reset signals for all
other components on the board.
