Cisco Systems manual VIP-4R/4T Installation and Configuration, H5985

Versatile Interface Processor Functions

Note The VIP port adapters themselves do not support OIR, nor are they FRUs.

The VIP uses a Reduced Instructions Set Computing (RISC), Mips 4600 processor for high performance, and has an internal operating frequency of 100 megahertz (MHz) and a 50-MHz system bus interface. The VIP has 8 megabytes (MB) of dynamic random access memory (DRAM) as the default DRAM configuration.

Figure 1 shows a VIP-4R/4T. The VIP firmware (microcode), which contains card-specific software instructions, resides in a Flash memory device in socket location U17. Single in-line memory modules contain the DRAM. For connector pinouts, refer to the section “4R Port Adapter Receptacles, Cables, and Pinouts” on page 34, or to the section “4T Port Adapter Receptacles, Cables, and Pinouts” on page 51. You can install VIPs in any available interface processor slots.
