Identifying Components in a 6780 Switch
The 13 slots in the rear of each 6780 switch contain PICs as shown in Figure 2-2.
6780 Switch Plug-In Cards (PIC)
The PICs share the common midplane interface and provide the physical interface for
each ServerNet link. For ServerNet clusters, the PICs in the 6780 switch provide a
variety of connections as described in Table 2-4, 6780 Switch PICs, on page 2-6 . For
information about PIC LEDs, refer to Firmware, Configuration, and FPGA Images on
page 2-16.
Single-mode fiber (SMF) can be used for high-speed long-distance signal
transmission. It provides greater bandwidth than multimode. Multimode fiber (MMF) is
optical fiber designed to carry multiple light rays or modes concurrently, each at a
slightly different reflection angle within the optical fiber core. Because the modes tend
to disperse over longer lengths, multimode fiber transmission is used for relatively
short distances.
