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:.
