Managing CMM Directory Content

Using the USB Flash Drive

An Alcatel-Lucent certified USB flash drive can be connected the CMM and used to transfer images to
and from the flash memory on the switch. This can be used for upgrading switch code or backing up files.
Additionally, automatic code upgrades as well having the capability to boot from the USB flash drive for
disaster recovery purposes are also supported. For the automatic upgrades and disaster recovery the USB
flash drive must be configured with the proper directory structure, depending on the platform, as noted in
the table below. Once the flash drive is properly mounted a directory named /uflash is automatically
created. Files can then be copied to and from the /uflash directory.
The directories below must be created on the USB flash drive for feature support.
