I/O Header for Thunderbolt
The JTBT1 header is a general purpose I/O header for a Thunderbolt add-on card.
PCI-E M.2 Connector (M.2 CONNECTOR)
The PCI-E M.2 connector is for devices such as memory cards, wireless adapters, etc. These
devices must conform to the PCI-E M.2 specifications (formerly known as NGFF). Also, the
M.2 socket on the motherboard supports PCI-E 3.0 x4 (32 Gb/s) SSD cards in the 2280 and
22110 form factors.
NC-SI Header for IPMI Support
A Network-Controller Sideband Interface (NC-SI) header is located at JNCSI1 on the
motherboard. Connect an appropriate cable from this header to an add-on card to provide the
out-of-band (sideband) connection between the onboard Baseboard Management Controller
(BMC) and a Network Interface Controller (NIC) for remote management. For the network
sideband interface to work properly, you will need to use a motherboard that supports NC-SI
and also need to have a special cable. Refer to the table below for pin definitions.
