CompactFlash Disk
The NPE-G2 has one CompactFlash Disk slot that uses CompactFlash Disks. The device in this slot is
always addressed as disk2: when using Cisco IOS command-line interface (CLI) commands.
CompactFlash Disks are smaller in size than Type 2 Flash Disks but provide the same AT Attachment
(ATA) interface and equivalent functionality. This interface complies with the ANSI ATA Interface
Document X3T13.1153 D Rev. 9 specification. The CompactFlash Disk provides 256 MB of storage
space.
The CompactFlash Disk has controller circuitry that allows it to emulate a hard disk and automatically
maps out bad blocks and performs automatic block erasure. The CompactFlash Disk also provides the
capability to allocate noncontiguous sectors, which eliminates the need for the squeeze command (which
was required with older-style linear flash memory cards to recover the space used by deleted files).
The CompactFlash Disk also supports the Cisco IOS File System feature, which provides a single
interface to all of the router's file systems, including the Flash Disks and flash memory, as well as
network file systems such as File Transfer Protocol (FTP) and Trivial FTP (TFTP) servers.
All CompactFlash Disks must be formatted before their initial use. CompactFlash Disks shipped with
Note
the NPE-G2 are formatted at the factory, but spare memory cards are not formatted.
