Every 8-port switch card in the system interconnect is numbered 8–15. This is
normal. The port number on the panel of the line card is only one element used to
identify a port. In port numbering discussions, a port is uniquely identified by the
rack number, chassis number, slot number, and the line card port number.
The backplane interface includes 8 SAN-2000 links num bered 0-7, corresponding
to the port numbering of the XBar16. Figure 3-4 show s the backplane of the GigE
switch card, and Figure 3-5 shows the backplane of the fiberoptic switch card. The
backplane interface also includes dual +12V power, and a serial-link interface to
the monitoring line card.
