Problems solved by technology

[0009] In summary, although the user can insert or extract the I / O card 14, the network card 16, and the SCSI card 18 in a hot-swappable manner, the processor add-in card 20 cannot be inserted or pulled out in a hot-swappable manner.
Because the processor add-on card 20 lacks the necessary power switching circuit and signal switching circuit in the PCI hot swap specification

Embodiment Construction

[0015] Please refer to figure 2 . figure 2 It is a functional block diagram of the PCI heat exchange bus 100 of the present invention. The PCI hot-swappable bus 100 is designed according to the specification of PICMG 2.1 R1.0, and the related documents of PICMG 2.1 R1.0 can be obtained from general PCI organizations (such as the International PCI Industrial Computer Association, PICMG). The PCI hot-swap bus 100 is built on a substrate 102 . The base board 102 includes a plurality of add-in card slots 104 and two processor slots 105 . All the add-in card slots 104 and the processor slots 105 are electrically connected to each other via the PCI hot-swap bus 100 . The add-on card slot 104 can be used to insert various hot-swappable add-in cards, for example, an I / O card 106 can be inserted for communicating with peripheral devices (such as a modem), or an SCSI card 108 can be inserted , used to control other SCSI interface devices (such as hard drives), or to install a netw...

Abstract

A processor add-on card is installed on the processor slot of a hot-swappable bus in a hot-swappable manner. The processor add-in card includes: a connection end, which enables the processor add-in card to be inserted into or pulled out of the processor slot of the hot-swappable bus in a hot-swappable manner; a signal switching circuit, connected to the processor add-in card The signal line of the card and the signal line of the heat-swap bus, and the signal switching circuit is electrically connected to the connection end so that the processor add-in card can be heat-swapped; a processor is electrically connected to the signal switching circuit; The power switching circuit controls the power supply of the processor add-on card.

Description

technical field [0001] The invention relates to a processor add-in card, in particular to a processor add-in card capable of heat exchange on a heat exchange bus. Background technique [0002] For today's society that relies more and more on computer equipment, the failure of computer equipment is increasingly unacceptable by users. Especially for computer equipment that provides communication functions or network services, due to its special operational requirements, when it fails, it may cause inestimable losses to the entire system. Therefore, in order to minimize the errors and downtime of computer equipment, computer manufacturers have adopted certain designs to solve the above-mentioned problems. For example, currently some motherboards have adopted a passive backplane architecture. There is almost no circuit on the passive substrate, and there is a processor slot for inserting a processor add-in card, and multiple add-in card slots for inserting other circuit boards...
