Embodiment 1

[0017] like figure 1 As shown, the NCSI signal management function switching circuit includes a BMC chip, a high-speed signal Switch chip, a first network card device and a second network card device.

[0018] The BMC chip adopts AST2500 chip, which can support NCSI management, FW control high-speed signal Switch chip channel selection, OCP network card device presence detection, ARM11 core, 800MHZ main frequency, 8GB SDRAM.

[0019] The high-speed signal Switch chip adopts TS3L501ERUAR chip.

[0020] The first network card device and the second network card device are respectively a PHY network card device and an OCP network card device.

[0021] The NCSI signal of the BMC chip is respectively connected to the PHY network card device and the OCP network card device through the channel 1 of the high-speed signal Switch chip. Channel 2 is connected to the PHY network card device, and channel 3 is connected to the OCP network card device.

[0022] The PHY network card device ...

Abstract

Embodiments of the invention disclose an NCSI signal management function switching circuit and a server. The circuit comprises a BMC chip, a high-speed signal Switch chip, a first network adapter device and a second network adapter device, and an NCSI signal of the BMC chip is connected with the first network adapter device and the second network adapter device separately through the high-speed signal Switch chip. The high-speed signal Switch chip has a channel switch enabling PIN, a second network adapter device present signal is connected with the channel switch enabling PIN of the high-speed signal Switch chip, so as to control high and low levels of the channel switch enabling PIN of the high-speed signal Switch chip, so that the NCSI signal link can be connected or disconnected, further, the NCSI signal of the BMC can select the channel to the first network adapter device and the second network adapter device. The circuit can automatically switch the NCSI management function, improve the self-adaptability and reliability of the network management function, realizes out-of-band management of the server, and is convenient to operate and maintain.

Description

technical field [0001] The invention relates to the field of server mainboard manufacture and inspection. Background technique [0002] With the rapid development of the Internet economy, the business of data centers continues to grow, and the number and scale of data centers increase rapidly, which puts forward higher requirements for out-of-band manageability and controllability of servers. [0003] Flexibility and reliability are a very important indicator requirement. Through out-of-band management, engineers can connect to the corresponding server through the network at any location to perform a series of management and maintenance, without having to stay in a noisy laboratory environment for a long time. NCSI (Network Controller Sideband Interface) is an industry standard for sideband interface network controllers defined by the Distributed Management Task Force to support server out-of-band management. [0004] At present, the conventional design method of server ma...
