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 your switch, you should:
Verify that there is a connection between the FTP or TFTP server and the
■
Switch 4210 (you can use the ping command to confirm the connection).
Verify that the FTP or the TFTP server is set up according to the manufacturer's
■
instructions and that it is enabled and pointing to the correct upload/download
directory.
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.
The flash space needed for the new files is approximately 3.3 MB. The size of the
flash storage is approximately 8 MB.
1 To check the contents of the flash, log on to your switch either using a telnet
connection or directly using the console to display the User View. Using the CLI,
enter:
<4210> dir
A file list similar to the following displays:
