This section describes how to upgrade files to your Switch from the 
Command Line Interface (CLI).

The basic procedure is to check that you have enough space available in 
flash memory, backup your existing Switch software, and then upgrade 
the Switch software. The following sections describe these steps in detail.

Before upgrading the software to your Switch from the CLI, it is 
important to check the contents of the flash to ensure that there is 
enough space to download the new files. 

1 To check the contents of the flash, logon to your Switch either using a 

telnet connection or directly using the console to display the User View in 
the CLI and enter the following:

<4200G> dir unit1>flash:

A file list similar to the following is displayed:

Directory of unit1>flash:/

The file system listing may also contain files called topology.top and 
configuration files (file suffix .cfg).

2 Any additional files should be considered for deletion to allow maximum 

space for downloading the new files. To delete a file from the list enter:

<4200G> delete/unreserved unit1>flash:/filename

CAUTION: Do not delete the topology.top file, or any configuration 
files (file suffix .cfg).
