1.Default SDRAM configuration is 512 MB for PRP-1 and 1-GB for PRP-2. Bank 1 (U15) must be populated first. You can use one or both banks to configure SDRAM combinations of 512 MB, 1 GB, or 2 GB for the PRP-1 and 1 GB, 2 GB, 3 GB, and 4 GB for the PRP-2. 1.5-GB configurations.and non-Cisco DIMM devices are not supported.

2.If both banks of the PRP-1 are populated, bank 1 and bank 2 must contain the same size DIMM.

3.SRAM is not user configurable or field replaceable.

4.NVRAM is not user configurable or field replaceable.

5.Flash memory SIMM is not user configurable or field replaceable.

6.ATA Flash disks are supported in the PRP-2; both ATA Flash disks and linear Flash memory cards are supported in the PRP-1.

7.Optional PRP-2 hardware. Non-Cisco compact disks are not supported.

8.Optional PRP-2 hardware. Non-Cisco hard disk drives are not supported.
