How to load new software

There are various ways of carrying out a firmware upload (which is the term
given to the installation of software), all of which produce the same result:

ELSA LANconfig

 

ELSA WEBconfig

Terminal programs

TFTP

All settings will remain unchanged by a firmware upload. All the same you
should save the configuration first for safety's sake (with 

Edit 

 Save

Configuration to File 

if using

ELSA LANconfig

, for example). 

If the newly installed release contains parameters which are not present in
the device's current firmware, the device will add the missing values using
the default settings.

ELSA LANconfig

When using 

ELSA LANconfig

, highlight the desired device in the selection list

and click on 

Edit 

 Firmware Management 

 Upload New Firmware

,

or click directly on the 

Firmware Upload

 button. Then select the directory

in which the new version is located and mark the corresponding file. 

ELSA LANconfig

 then tells you the version number and the date of the

firmware in the description and offers to upload the file. The firmware you
already have installed will be replaced by the selected release by clicking

Open

.

You also have to decide whether the firmware should be permanently
activated immediately after loading or set a testing period during which you
will activate the firmware yourself. To activate the firmware during the set
test period, click on 

Edit 

 Firmware Management 

 After upload, start

the new firmware in test mode

.

ELSA WEBconfig

Launch your browser and enter the IP address of the unit in the address field.
For example, if your 

ELSA LANCOM Business

 has the IP address

194.162.200.17, enter: 'http://194.162.200.17'.

On the starting page, follow the 'Upload new Firmware' link. In the next
window you can browse the folder system to find the firmware file and click

Upload

 to start the installation.
