Downloading a Software Upgrade
You can upgrade the operational software in the ELH100-12/24TX hub
without physically opening the hub or being in the same location. The
software storage sector in the flash memory of the hub is
reprogrammable, allowing you to easily download software feature
enhancements and problem fixes to the hub from a local or remote
location.
Software can be downloaded to the hub 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 hub. This operation
takes approximately 40 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 matter of minutes, and can be used to upgrade an ELH100-12/
24TX hub 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 ELH100-12/24TX
hub software, requiring the least amount of equipment and configuration.
To download hub software via the serial port, do the following:
1. Select XMODEM Download from the Main Menu.
2. Select “Upgrade FLASH and reboot.”
3. Select <Start XMODEM Download>.
