Server serial port switching apparatus and method, and server

Abstract

The present invention discloses a server serial port switching apparatus and method, and a server. The server serial port switching apparatus comprises a panel interface with a third signal transmitting end, a BMC serial port with a first signal transmitting end, a system serial port with a second signal transmitting end and a conducting selection switch, which are all arranged on a server, as well as a switching control module located in a BMC. The first signal transmitting end is connected to the third signal transmitting end via the conducting selection switch and a state of signal conduction is a first state; the second signal transmitting end is connected to the third signal transmitting end via the conducting selection switch and a state of the signal conduction is a second state; and the switching control module is used for controlling, according to a switching instruction, the conducting selection switch to switch between the first state and the second state. By means of the apparatus and method, and the server, which are disclosed by the present invention, the cumbersome operation caused by switching between the BMC serial port and the system port using a switching button set in the prior art is removed, and the defect that the BMC serial port does not support information inputting is overcome.

Description

technical field [0001] The invention relates to the communication field, in particular to a server serial port switching device and method, and a server. Background technique [0002] The server usually consists of two parts: the system part responsible for business processing, and the BMC (Baseboard Management Controller, Baseboard Management Controller) part, wherein, as the management unit of the server, the BMC is responsible for managing and monitoring the system part of the server. The serial port is the most basic information exchange interface. Both the system part and the BMC part need to use the serial port to output the underlying operating status information. At the same time, in the process of maintenance and troubleshooting, the serial port is also needed to input debugging commands and view detailed debugging information for convenience. For troubleshooting, it is necessary to have both the system serial port and the BMC serial port. Considering the convenien...

Problems solved by technology

However, this method requires people to go to the site to press the switch button on the single board to complete the switching of the serial port, which is very troublesome to operate. Moreover, because the received signal of the BMC serial port cannot be connected to the panel interface, the BMC serial port cannot support information interaction. , can only output information but does not support input information
