Downloading a Software Upgrade
You can upgrade the operational software in the ELS100-24TX 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, allowing you to easily download software feature
enhancements and problem fixes to the switch from a local or remote
location.
Software can be downloaded 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 an ELS100-24TX
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 ELS100-24TX
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).
When the XMODEM procedure finishes, the following message
prompt displays:
Software download successfully completed XMODEM
download. Please wait while program flash is being
written. Software downloader is exiting after
successful download to flash. Please wait while
system initializes.
The system software will reinitialize and display the login prompt.
