Processor Switch ServerNet Connections
ServerNet connections to the system I/O devices (storage disk and tape drive as well as Ethernet
communication to networks) radiate out from the p-switches for both the X and Y ServerNet fabrics
to the IOAMs in one or more IOAM enclosures or the CLIMs.
ServerNet cables connected to the p-switch PICs in slots 10 through 13 come from the LSUs and
processors, with the cable connection to these PICs determining the processor identification. (See
“LSUs to Processor Switches and Processor IDs” (page 70). Cables connected to the PICs in slots
6 through 9 can connect to one or more networking CLIMs, starting with slot 9. If more slots are
needed for networking CLIMs, then you can also use slots 4 and 5, if 4 is not needed for S-series
networking. Cables connected to the PICs in slots 4 though 9 connect to Storage CLIMs, one or
more IOAM enclosures or to NonStop S-series I/O enclosures equipped with IOMF 2 CRUs. This
illustration shows the connections to the PICs in a fully populated p-switch:
