Downloading a Software Upgrade
You can upgrade the operational software in the switch without physically
opening the switch or being in the same location. The software storage sector in
the flash memory of the switch is reprogrammable. This feature allows you to
easily download software feature enhancements and problem fixes to the switch
from a local or remote location.
You can download software to the switch in two ways:
■ Via the serial port. This procedure is an out-of-band operation that
copies the software through the serial port to the switch. This operation
takes approximately 10 minutes and requires minimal configuration.
■ Via TFTP download. This procedure uses a TFTP server connected to
the network and downloads the software using the TFTP protocol. A
TFTP download is much faster than a serial download, requiring only a
few seconds, and can be used to upgrade a switch that is not physically
proximate. The disadvantage is that this method requires a TFTP server
and additional setup.
Downloading Via the Serial Port
A serial download is the easiest method to upgrade the switch software,
requiring the least amount of equipment and configuration.
To download switch software via the serial port, do the following:
1.
Select Download Software Menu from the Main Menu.
2.
Select Start XMODEM Download.
The following message prompt displays:
Software downloader is running.
Software downloader request: Please start XMODEM
transfer (9600, N, 1).
(Please ignore any characters that may appear on the next line).
3.
Send the file using the XMODEM protocol from your computer
application (the procedure varies depending upon the application used).
