Description

Riser card modules and expansion card devices

The invention relates to an adapter card module and an expansion card device.

In the past, most 1U servers were equipped with two PCIE-type expansion cards. In order to meet users' needs for improving server performance, server manufacturers are currently trying to increase the number of expansion cards to four in the space of a 1U server. Each of the four expansion cards needs to be paired with a riser card, and the riser card needs to be electrically connected to the motherboard through cables. As a result, the number of electrical connectors needs to be increased on the motherboard to accommodate these cables.

Under the current server architecture, these cables cannot be randomly assembled into the electrical connectors on the motherboard, but there are electrical connectors that limit the assembly of each cable. However, the motherboard has many electrical connectors, and it is easy for personnel to assemble cables into the wrong electrical connectors, causing problems in server operation. Therefore, researchers in this field are currently working on solving the aforementioned problems.

The present invention provides an adapter card module and an expansion card device that can reduce the probability of personnel assembling cables to wrong electrical connectors.
