The RSP8 contains the system CPU, the system software (on a Flash Disk), the system memory components, and two PC Card slots, and it maintains and executes the management functions that control the system.

Although no monitoring of ±12V or temperature is done by the RSP8, a comparator device ensures that ±12V is maintained within the normal operating ranges, and three temperature sensors on the RSP8 send temperature information to the chassis interface (CI) card. The CI card reports all voltage and temperature readings, and these readings are available through standard software commands for environmental monitoring. The RSP8 uses a software-controlled configuration register, so you do not have to remove the RSP8 to configure jumpers. There are no user-configurable jumpers on the RSP8.

The RSP8 contains the following components:

•R7000 Reduced Instruction Set Computing (RISC) processor, used for the CPU with 256 KB on-chip secondary (L2) cache. The CPU runs at an external bus clock speed of 100 MHz and an internal clock speed of up to 250 MHz.

•Up to 256 megabytes (MB) of parity-protected, dynamic random-access memory (DRAM) on two dual in-line memory modules (DIMMs); 64 MB of DRAM is the default shipping configuration. DRAM comes preconfigured as either two 32-MB DIMMs or one 64-MB DIMM.
