March 2005 Files and Directories 37
Image Files
Image files (those files with .img extensions) contain execut-
able code that provides support for the system, NI modules,
and network functions. In other words, they serve as essential
drivers for switch and network operations.
Although these files may be backed up to the root flash direc-
tory or any user-defined subdirectory, they must be present in
the /flash/working and /flash/certified directories for the
switch to operate and pass traffic.
If you delete all copies of an image file, you will be required to
contact Alcatel Customer Support for replacements. There-
fore, it is recommended that you keep backup copies on your
computer’s hard drive or a locally-accessible server.
