Operating
2.3 Maintenance
The actual device generation with IPv6 and SSL allows all maintenance functions in
the web interface to be carried out on the Maintenance Page
.
Maintenance in the web interface
The following functions are available from the maintenance web page:
· Firmware Update
· Change the SSL certificate
·
Load and save the configuration
·
Restart the device
·
Factory Reset
· Jump into the Bootloader
· Delete the DNS cache
Upload Firmware, Certificate or Configuration
On the Maintenance Page , select the required file with "Browse .." in the sections
"Firmware Update", "SSL Certificate Upload" or "Config Import File Upload" and press
"Upload". The file is now transferred to the update area of the device and the contents
are checked. Only now, pressing the "Apply" button will permanently update the data,
or abort with "Cancel".
Only one upload function can be initiated with a reboot, eg. you cannot transmit
firmware and configuration at the same time.
If after a firmware update, the web page is not displayed correctly anymore, this
may be related to the interaction of Javascript with an outdated browser cache. If a
Ctrl-F5 does not help, it is recommended that you manually delete the cache in the
browser options. Alternatively, you can test start the browser in "private mode".
During a firmware update, old data formats are sometimes converted to new struc-
tures. If an older firmware is newly installed, the configuration data and the energy
meters may be lost! If the device then does not run correctly, please restore the factory
settings (e.g. from the Maintenance Page
).
Actions in Bootloader mode
If the web interface of the device is no longer accessible, the device can be put into
Bootloader mode (see chapter Bootloader activation
). The following functions can
be executed using the GBL_Conf.exe application:
· Set IPv4 address, net-mask and gateway
·
Turn HTTP password on and off
·
Turn IP-ACL on and off
·
Factory Reset
· Jump into the bootloader (can be switched on and off)
· Restart the device
For devices with relays, entering or exiting the bootloader mode does not change
the state of the relays as long as the operating voltage is maintained.
