Crosstown Cable
The crosstown cables are similar to the CrayLink Interconnect and Xpress cables, so the
same cautionary guidelines apply. The crosstown cables are encased in a plastic-ribbed
coating and are slightly more ruggedized. The cables are used to connect to external
peripherals and provide the same I/O performance as the CrayLink Interconnects and
Xpress link cables.
PCI Carrier Assembly
The peripheral connector interface carrier assembly can house up to three third-party
PCI boards (see Figure 2-11). Two of the PCI boards can be full-size boards. The third PCI
slot accepts only half-size boards. The PCI carrier assembly provides up to 75 watts of
power.
