Motherboard Connections
This section describes the connections on the motherboard and provides pinout definitions.
Note that depending on how the system is configured, not all connections are required. The
LEDs on the motherboard are also described here. A serverboard layout indicating component
locations may be found in Chapter 1.
Please review the Safety Precautions in Chapter 3 before installing or removing components.
4.1 Headers and Connectors
Onboard Fan Header
Two 4-pin fan headers (FAN1/FAN2) are located on the motherboard to provide CPU/system
cooling. These fan headers support both 3-pin fans and 4-pin fans; however, onboard fan
speed control is available only when all 4-pin fans are used in the motherboard. Fan speed
control is supported by a thermal management setting in the BMC (Baseboard Management
Controller). See the table below for pin definitions.
Super I/O Module (SIOM)
A Supermicro proprietary Super I/O module is located at JSIOM1. This I/O module supports
a PCI-E 3.0 x16 add-on card on the X11DSN-TS.
TPM Header
The JTPM1 header is used to connect a Trusted Platform Module TPM/Port 80, which is
available from a third-party vendor. A TPM/Port 80 connector is a security device that supports
encryption and authentication in hard drives. It allows the motherboard to deny access if the
TPM associated with the hard drive is not installed in the system.
