Chapter 4 Removing and Installing the NSE
Installing and Using the CompactFlash Disk
Caution
When inserting the SODIMM, use firm but not excessive pressure. If you damage a socket, you will have
to return the NSE-100 to the factory for repair.
Step 5
Press the SODIMM down until it is secured by the spring latches.
Step 6
When the SODIMM is installed, check both alignment holes on the SODIMM and ensure that the
spring latch is visible. If it is not, the SODIMM is not seated properly. If the SODIMM appears
misaligned, carefully remove it and reseat it in the socket. Push the SODIMM firmly back into the
socket until the spring latches snap into place.
This completes the SDRAM SODIMM installation procedure. To reinstall the NSE-100 in the chassis,
see the
“Inserting the Network Services Engine” section on page 4-7

Installing and Using the CompactFlash Disk
This section provides instructions for installing, removing, and using CompactFlash Disks in the
Cisco 7304 router.
On the NSE-100 and NSE-150, CompactFlash Disks provide storage space for your configuration files,
Cisco IOS software images, and so forth.
This section includes the following subsections:

Product Description
CompactFlash Disks are Flash memory-based devices that conform to the PC Card (formerly PCMCIA)
standard, and that present an AT Attachment (ATA) interface to the system. This interface complies with
the ANSI ATA Interface Document X3T13.1153 D Rev. 9 specification.
The CompactFlash Disk is more flexible than linear Flash memory because the CompactFlash Disk has
controller circuitry that allows it to emulate a hard disk and that automatically maps out bad blocks and
performs automatic block erasure. Further, the CompactFlash Disk provides the capability to allocate
noncontiguous sectors, which eliminates the need for the
squeeze
command (previously required with
linear Flash memory cards).
The CompactFlash Disk is a Type-2 PC Card device. The CompactFlash Disk provides increased
Flash-based memory space for storage of system configuration files, Cisco IOS software images, and
other types of system-related files.
Table 1-3
provides memory information for the CompactFlash Disk.
The Cisco IOS File System feature provides a single interface to all file systems your system uses:
•
Flash memory file systems—CompactFlash Disks, onboard Flash memory, linear Flash memory
cards
•
Network file systems—File Transfer Protocol (FTP), Remote Copy Protocol (rcp), and TFTP
•
Any other endpoint for reading or writing data—NVRAM, the running configuration, ROM, raw
system memory, system-bundled microcode, Xmodem, Flash load helper log, modems, and BRI
MUX interfaces
