Termination Card
You must install a termination card in any vacant processor card slot to ensure reliable system operation.
The termination card contains AGTL+ termination circuitry, clock signal termination, and Test Access Port (TAP) bypassing for the vacant connector. The system does not boot unless all slots are occupied with a processor or termination card.
Server Monitor Module Connector (J7H1)
The baseboard supports the Server Monitor Module feature connector. The table below shows the pinout of the
On the SKA4 baseboard, pins 1, 9, 15, and 17 are connected to SMI_L, NMI, SECURE_MODE, and CHASSIS_INTRUSION. Some server systems do not monitor these signals.
