5.2.10 SLOT 3 Connector J19
Slot 3 and its dedicated sideband signal connector J25 provide the possibility to verify the SGMII and XAUI capability of the
mounted COM Express® module. The main connector J19 provides up to four GigEthernet SGMII interfaces or one XAUI interface
whereas the sideband connector adds several sideband signals which are necessary for operation of the S0010 SGMII-Adapter
Card or the S0011 XAUI-Adapter Card or to assist in designing special custom adapter cards.
