The XIt1043 is a highly configurable 6U VPX Rear Transition Module (RTM), which supports I/O breakout from the XChange3100 6U VPX Ethernet switch and select X-ES 6U VPX single board computers (SBCs). When installed in the RTM slot of an appropriate 6U VPX backplane, the XIt1043 routes I/O signals from the switch’s or SBC’s rear panel to connectors on the XIt1043 so that the signals can be connected to external equipment.
The XIt1043 has twenty iPass connectors for fat pipes from RP0, RP1, RP2, RP3, RP4, and RP5, allowing the fat pipes to be connected in various network topologies using iPass cables. It also has four RJ-45 connectors for the four 10/100/1000BASE-T Ethernet ports from single-ended pins on RP3, RP4, RP5, and RP6. The RP6 connector can be configured to support eight additional 10/100/1000BASE-T Ethernet ports or four additional fat pipes.
The XIt1043 supports SerDes-to-copper conversion for both XAUI and 1000BASE-X signals. Two XIt3000 XMC I/O modules can be installed on the XIt1043 to convert a total of four XAUI signals to four 10GBASE-T signals. The XAUI signals are routed to the XIt3000 modules via iPass connectors. Similarly, four 1000BASE-X signals can be routed through an iPass connnector and converted to 1000BASE-T by onboard Ethernet PHYs.
