Problems solved by technology

[0004] Traditional servers need to use cables if they want to place PCIE devices in other boards or cabinets. For hot-swappable boards or cabinets, it is very troublesome to organize and plug cables
In addition, traditional connectors are often welded, and it is very troublesome to replace if damaged

Embodiment Construction

[0018] The method of the present invention will be described in detail below with reference to the drawings, such as figure 1 with figure 2 Shown.

[0019] 1. Place the PCIE GEN2 re-drive chip on the sending end of the PCIE main control chip, and the PCIE TX signal will be re-driven to the crimp connector.

[0020] 2. The PCIE TX signal reaches each PCIE slot through the connector, and the PCIE RX signal is sent out by the PCIE device, re-driven, and transmitted to the connector, and finally reaches the PCIE main control chip on the server motherboard. Each PCIE slot corresponds to a hot-removal button and a hot-swap indicator. When the hot-swap controller supplies power to the slot, the hot-swap indicator is on; when hot removal is required, press the hot-removal button , The system will notify the hot-swap controller to turn off the slot voltage after processing, and the hot-swap prompt light is off.

[0021] There are two buttons (hot insert button and hot remove button) on the...

Abstract

The invention provides a server-based method for designing a hot-swappable PCIE equipment box. The method comprises the following steps that: a PCIE GEN2 redriving chip is added at a sending end of a PCIE signal; the PCIE signal is redriven and transmitted by at least 40-inch distance on a PCB board made of a common FR4 material; the signal is transmitted to a PCIE assembly board through a crimp connector and finally transmitted to a PCIE slot; the PCIE equipment box is provided with a hot-plugging button AN; a triggering system interrupts if the button is pressed; the system firstly scans existing pins of all the equipment in the PCIE box; a hot-swap controller is noticed to supply power to the corresponding slot if the equipment exists; then a system PCI bus enumerate the equipment again; drivers of the PCIE equipment are loaded; a hot-swap LED indicator light of the PCIE equipment is lightened at the moment; and a hot-swap prompting light of a box body is lightened if only one LED light is lightened so as to complete hot-plugging actions of the box body and the equipment.

Description

Technical field [0001] The invention relates to the field of computer hardware, in particular to a method for designing a server-based hot-swappable PCIE equipment box. technical background [0002] In the computer field, PCIE equipment has the characteristics of large bandwidth, high speed, stable operation, and good compatibility. It is widely used by server manufacturers. Whether it is in display, storage, network communication and many other aspects, there are shadows of PCIE equipment everywhere, so how Better management of PCIE devices and more convenient use of PCIE devices are issues that server manufacturers have been paying attention to for a long time. [0003] In a large server system, it is not easy to integrate many PCIE devices. Due to the limitation of wiring length, PCIE devices can only be placed around the main control chip. Multi-channel servers use multiple PCIE main control chips, which will inevitably lead to PCIE devices being distributed everywhere, occupy...
