Cisco 1GB Memory - 1x 1GB DIMM MEM-PRP2-1G Benutzerhandbuch

The PRP-3 contains the following components:

Power PC Processor—Power PC 8641D Dual Processor Central Processing Unit (CPU) e600 cores 
running at 1.3 GHz each.

Memory—Default internal and external compactflash of 2 GB each (2 x 2 GB = total 4 GB) and 
provides an option for upgrading the compact flash to 8 GB (2 x 4 GB).

Hard disk drive—80-GB hard disk drive installed on the PRP-3 board.

SDRAM—2 GB each for two DDR2 DRAMs (2 x 2 GB) for a total of 4 GB is the default shipping 
configuration. Option to upgrade to 8 GB (2 x 4 GB). 

NVRAM—2 MB of nonvolatile RAM (NVRAM). NVRAM is not user configurable or field 
replaceable.

Sensors—Air-temperature sensors for environmental monitoring.

For Cisco IOS XR Release 3.7.0 and later releases, SDRAM and Compact Flash memories require 2 GB 
capacity.
