Downloading a Software Upgrade

You can upgrade the operational software in the ELS100-24TXG switch

without physically opening the switch or being in the same location. The

software storage se ctor in the flash memo ry of the switch is

reprogrammable, al lowing you to easily download software fe ature

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 so ftwar e usin g the TFTP proto col.

A TFTP download is much faster than a serial download, requiring

only a few seconds, and can be used to u pgra de an ELS1 00-24 TXG

switch that is not physically proxim at e. T he di sad v ant age i s tha t thi s

method requires a TFT P server and additi onal setup.

Downloading Via the Serial Port

A serial download is the easiest method to upgrade the ELS100-24TXG

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 progr am flash is bei ng

written. Software downloader is exiting after
