An interface apparatus for installing an add-in module to an information handling system includes the add-in module and an add-in module socket. The add-in module includes a card-edge connector on a first edge of the add-in module, and an electrical contact finger on a second edge of the add-in module. The add-in module socket is affixed to the information handling system and receives the add-in module. The add-in module socket includes a card-edge connector interface for receiving the card edge connector, and a slot channel for receiving the second edge of the add-in module. The slot channel includes an electrical contact pad configured such that, when the add-in module is installed into the add-in module socket, a current is provided between the add-in module socket and the add-in module through the electrical contact pad and the electrical contact finger.

Memory module connection interface for power delivery

An interface apparatus for installing memory modules to an information handling system includes a riser card and an adapter. The riser card includes a first card-edge connector on a first edge of the riser card, and a second card-edge connector on a second edge of the riser card. The first card-edge connector is associated with a first interface and the second card-edge connector is associated with a second interface. The adapter includes a first socket on a first side of the adapter, and a second socket on a second side of the adapter opposite to the first side. The first socket and the second socket are associated with the second interface. The first socket is configured to receive the second card-edge connector of the riser card. The second socket is configured to receive a memory module.

CXL memory expansion riser card

A method for identifying a short circuit at a circuit node may include activating a current source to drive a signal at the circuit node, and sampling a voltage level at the circuit node at a particular time. The method may further include determining that the circuit node is not shorted to another circuit node if the voltage level at the first circuit node exceeds a threshold value; and determining that the first circuit node is shorted to another circuit node if the voltage level at the first circuit node does not exceed the threshold value.
