Figure 4-4 Rear Panel Items
The rear panel of the MPX module has the following items:
• Power connector. This connector connects the MPX module to an AC power outlet.
• Console port. This DB-9 serial port (console and diagnostic port) enables you to
connect a system console to the L1 controller on the MPX module.
• Serial port. This DB-9 RS-232/RS-422 serial port, which connects a serial device
such as a printer or modem to the module, is not operable.
• L1 port (USB type B). This Universal Serial Bus (USB) type B connector connects the
MPX module's L1 controller to an L2 controller.
• XIO connector. This Crosstown2 connector connects the MPX module to an
InfiniteReality graphics pipeline. This connection is made with a NUMAlink 3 cable
at 800 MB/s in each direction.
• XIO connector LEDs. The XIO connector has two LEDs. These LEDs are located
to the right of the XIO connector. One LED lights yellow to indicate that both
the MPX module and the InfiniteReality graphics pipeline to which the MPX
module is connected are powered on. The other LED lights green when the
MPX module link to the graphics pipeline is established.
• NUMAlink connector. This NUMAlink 3 connector connects the MPX module to
one of the following modules: base compute module, expansion compute module,
NUMAlink module, or PCI expansion module. This connection is made with a
NUMAlink 3 cable at 1.6 GB/s in each direction.
