Table 1-7 lists supported flash disk sizes and Cisco part numbers.

PRP-3 Compact Flash

PRP-3 provides more flash memory than PRP-2. PRP-3 uses flash memory to

store Cisco IOS XR software images. PRP-3 includes a default internal flash

memory of 2 GB and also has an external flash memory of 2 GB. A flash memory

upgrade option is also available for a total of 8 GB (2 x 4 GB).

PRP-2 and PRP-3 compactflashes are not compatible with each other and hence

PRP-2 compactflash cannot be used in PRP-3 and vice versa. PRP-3 uses

Multiword DMA to access the compactflash device, a PRP-2 compactflash does

not support this access type.

Note The PRP-3 external CompactFlash disk replaces the two PCMCIA slots

of PRP-2. The external CompactFlash disk can be installed or removed

from the PRP-3 front panel. The internal CompactFlash disk memory is

denoted as compactflash, while the external CompactFlash disk is

denoted as disk0:.
