Micro-telecom computing architecture system, carrier board hub module, and port configuration method for pci‑e switches

Abstract

The invention relates to a micro telecommunication computing architecture system, a carrier board hub module and a port configuration method of a PCI-E switch, the method comprising the following steps: coupling the configuration pins of the PCI-E switch to the input of the carrier board manager Output pin; the carrier board manager sends a control signal to the PCI-E switch to dynamically configure each port of the PCI-E switch as an uplink port or a downlink port. In the case of minor changes to the hardware circuit, make full use of the control function of the carrier board manager to configure the ports of the PCI-E switch, thereby eliminating the need to add dedicated configuration circuits, reducing the hardware overhead of the system, and real-time Controlling the port level status of the PCI-E switch realizes the dynamic configuration of the ports of the PCI-E switch to meet the needs of different situations, so that there is no need to use reserved parts or DIP switches to change the configuration. It effectively saves devices such as pins, jumper caps, and toggle switches added to realize the port configuration selection of the PCI-E switch, and saves PCB board space.

Description

technical field [0001] The invention relates to a port configuration method, in particular to a port configuration method of a micro-telecom computing framework system, a carrier board hub module and a PCI-E switch. Background technique [0002] The Micro Telecommunications Computing Architecture (Micro TCA, Micro Telecommunications Computing Architecture) system is a platform specification developed by the Peripheral Component Interconnect (PCI, Peripheral Component Interconnect) Industrial Computer Manufacturers Association (PICMG, PCI Industrial Computer Manufacturers Group). Mezzanine Card) module to build a small-capacity and low-cost large-scale communication platform, which is mainly used in small telecommunication equipment or enterprise-level communication equipment such as central computer rooms. [0003] A micro telecom computing architecture system usually includes a chassis, a backplane, a power module, a carrier hub module (MCH, MicroTCA Carrier Hub), an advanc...

Problems solved by technology

[0007] The purpose of the present invention is to provide a port configuration method of a PCI-E switch, which aims to solve the problem of the port configuration of the PCI-E switch in the prior art, where the configuration cannot be changed, that is, the properties of the port cannot be changed, Unable to adapt to new needs; professionals are required to realize it, and ordinary users do not know how to operate, which is not convenient for large-scale promotion; for multi-port carrier board hub modules, a large number of toggle switches are required, which is troublesome to operate; switch materials occupy PCB Board space, small boards are difficult to implement, etc.
