Disable file system
NOTE:
Performing the following steps on the TN799DP (C-LAN) or TN2501AP (VAL) circuit
packs removes only the
ftplogin
and the
ftppassword
. The allocated memory for the file
system remains reserved for the session.
To free up resources on the source circuit pack, you must delete the new firmware image files and disable
the file system.

UUCSS
and press Enter to disable the file system on the source
circuit pack.
NOTE:
This command is successful only if no files remain on the source circuit pack.
This completes the self- and C-LAN-distributed download procedures.

Aborting a firmware download
You can only abort (disable/cancel) a scheduled download that has not yet started. Any download
currently in progress to a circuit pack finishes. For example, if you had scheduled a C-LAN distributed
download to multiple targets and the download was in progress to the first circuit pack when you disabled
the download, then the download would stop after the completion of the first circuit pack’s download and
the remainder of the circuit packs would not receive the download.
To abort a self or C-LAN-distributed firmware download, enter the SAT command
disable firmware
download
.
Testing firmware download
You can test a self- or C-LAN-distributed firmware download either before a scheduled download has
begun or after an attempted download has reported errors.
1
Type
test firmware download
and press Enter to display the Test Results screen.
If the download has already begun, the test is denied.
