Description

technical field

[0001] The invention relates to the technical field of server board design, in particular to a safety card, a safety card slot and a board. Background technique

[0002] At present, the PCIE (PCI-Express, bus and interface standard) card slot is widely used in servers because of its advantages of being easy to use and capable of expanding a variety of different devices. With different security requirements, different customers have different opinions on whether to use TPM (Trusted Platform Module, security chip).

[0003] In the current design, the TPM is mainly designed to be integrated on the main board or connected to an external TPM card with a connector. The former method integrates the TPM security chip on the main board. When the customer does not need the TPM, the cost is higher. The latter method connects the TPM security chip to the external TPM card with a connector, although the cost is reduced, but when the external TPM card needs a connecting l...
