Description of the drawings
Fig. 1 is the circuit connection diagram of embodiment 1.
Specific embodiment
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As shown in Figure 1, NCSI signal management function switch circuits, include BMC chip, high speed signal Switch chips,
One network card equipment and the second network card equipment.
BMC chip uses AST2500 chips, can support NCSI management, FW control high speed signal Switch chip channel choosings
It selects, OCP network card equipments detect in place, ARM11 kernels, 800MHZ dominant frequency, 8GB SDRAM.
High speed signal Switch chips use TS3L501ERUAR chips.
First network card equipment and the second network card equipment are respectively PHY network card equipments and OCP network card equipments.
The NCSI signals of BMC chip by high speed signal Switch chip channels 1 respectively with PHY network card equipments and OCP nets
Card apparatus connects.Channel 2 connects PHY network card equipments, and channel 3 connects OCP network card equipments.
PHY network card equipments include the PCH chips being connected with each other and PHY network interface cards.
BMC chip FW controls the channel of signal and OCP network card equipments signal in place also with high speed signal Switch chips to cut
Enabled PIN connections are changed, signal and OCP network card equipments signal in place can be controlled to control high speed signal Switch by BMC chip FW
The low and high level variation of the enabled PIN of chip channel switching, realizes the break-make variation of NCSI signal links, and then realizes BMC's
