Product Overview
In addition to the functionality listed for the PRP-1, the PRP-2 provides the following additional functions:
•One IEEE 802.3 10/100/1000-megabits-per-second (Mbps) Ethernet port
•Two building integrated timing system (BITS) ports for connecting to an external clock source
PRP Components
The PRP-1 contains the following components:
•PowerPC processor—Motorola PowerPC 7450 central processing unit (CPU). The CPU runs at an external bus clock speed of 133 MHz and an internal clock speed of 667 MHz.
•SDRAM—Up to 2 gigabytes (GB) of Cisco-approved synchronous dynamic random-access memory (SDRAM) on two dual in-line memory modules (DIMMs). 512 MB of SDRAM is the default shipping configuration. SDRAM is field replaceable only when using Cisco-approved DIMMs.
•SRAM—2 megabytes (MB) of static random-access memory (SRAM) for secondary CPU cache memory functions. SRAM is not user configurable or field replaceable.
•NVRAM—2 MB of nonvolatile RAM (NVRAM). NVRAM is not user configurable or field replaceable.
•Memory—Additional memory components include onboard Flash memory and up to two Flash disks.
•Sensors—Air-temperature sensors for environmental monitoring.
