Nortel Networks 4050 User Manual

760 Chapter 15 Upgrading or reinstalling the software

320818-A

If needed, the file name can be prefixed with a search path to the directory on 
the TFTP/FTP/SCP/SFTP server.

If you are using anonymous mode when downloading the software package 
from an FTP server, the following string is used as the password (for logging 
purposes):
admin@hostname/IP.isd. 

The Nortel SNAS 4050 can hold up to two software versions simultaneously. To 
view the current software status, use the 

 command. 

When a new version of the software is downloaded to the Nortel SNAS 4050, the 
software package is decompressed automatically and marked as unpacked. After 
you activate the unpacked software version (which causes the Nortel SNAS 4050 
to reboot), the software version is marked as permanent. The software version 
previously marked as permanent will then be marked as old.

For minor and major releases, the software upgrade occurs in synchronized 
fashion among the set of Nortel SNAS 4050 devices in a cluster. If a Nortel 
SNAS 4050 device in a cluster is not operational when the software is upgraded, it 
will automatically pick up the new version when it is started.

Note: If more than one software upgrade has been performed on a 
cluster while a Nortel SNAS 4050 device has been out of operation, the 
software version currently in use in that cluster must be reinstalled on 
that Nortel SNAS 4050 device. For more information about how to 
perform a reinstall, see
