The File System
The 7750 SR OS file system is used to store files used and generated by the system, for example,
image files, configuration files, logging files and accounting files.
The file commands allow you to copy, create, move, and delete files and directories, navigate to a
different directory, display file or directory contents and the image version.
Compact Flash Devices
The file system is based on a DOS file system. In the 7750 SR-Series, each control processor can
have up to three compact flash devices numbered one through three. The names for these devices
are:
•cf1:
•cf2:
•cf3:
The above device names are relative device names as they refer to the devices local to the control
processor with the current console session. As in the DOS file system, the colon (“:”) at the end of
the name indicates it is a device.
The compact flash devices on the 7750 SR-Series routers are removable and have an
administrative state (shutdown/no shutdown).
NOTE: To prevent corrupting open files in the file system, you should only remove a compact
flash that is administratively shutdown. 7750 SR OS gracefully closes any open files on the
device, so it can be safely removed.
