The web page provides an overview of the energy measurement values of all phases,
as well as the external sensors, provided that they are connected.
The column "Residual Current" is only visible on models that support this feature.
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
16

15
Expert PDU Energy 8311 © 2021 GUDE Systems GmbH
Operating
·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.
The GBL_Conf.exe program is available free of charge on our website www.gude.info
and can also be found on the enclosed CD-ROM.

Interface GBL_Conf
To check the network settings with GBL_Conf.exe, start the program and choose "All
Devices" in the "Search" menu. From the list select the appropriate device. The lower
part of the left half of the window now shows the current network settings of the device.
If the IP address is displayed with the default settings (192.168.0.2), either no DHCP
server is present on the network, or there could be no free IP address assigned to it.
·Activate the Bootloader Mode (see Chapter Bootloader Mode) and choose in menu
"Search" the item "Bootloader-Mode Devices only"
·Enter the desired settings in the edit window and save them with "Save Config".
·Deactivate the boot loader mode for the changes to take effect. Select again "All
Devices" in the "Search" menu of GBL_Conf.exe.
The new network configuration is now displayed.
Factory Reset
The device can be reset to the factory default via the web interface from the Mainten-
ance Page or from the Bootloader mode (see chapter Bootloader activation ). All
TCP/IP settings are reset in this operation.
If a unit is set to factory defaults, an uploaded certificate or updated firmware will
be preserved.
2.3.1 Maintenance Page
This section provides access to important functions such as Firmware Update or Re-
start Device. It is advisable to set an HTTP password for this reason.
16 19

17
Expert PDU Energy 8311 © 2021 GUDE Systems GmbH
Operating
Firmware Update: Start a firmware update.
SSL Certificate Upload: Saves your own SSL certificate. See chapter "SSL " for the
generation of a certificate in the right format.
Config Import File Upload: Loads a new configuration from a text file. To apply the new
configuration, a "Restart Device" must be executed after the "Upload".
Config File Export: Saves the current configuration in a text file.
Saving the configuration should only be carried out in an SSL connection, since it
contains sensitive password information (even if it is encrypted or hashed).
Restart Device: Restarts the device without changing the status of the relays.
Some functions such as a firmware update or changing of the IP-address and
HTTP settings require a restart of the device. A jump to the boot loader or a restart of
the device lead by no means to a change of the relay states.
Restore Fab Settings and Restart Device: Performs a restart and resets the device to
factory default .
Enter Bootloader Mode: Jumps into bootloader mode, where additional settings can be
made with GBL_Conf.exe.
Flush DNS Cache: All entries in the DNS cache are discarded and address resolutions
are requested again.
Config/Status View: status.html: Displays the status.html page with the JSON data.

Config/Status Download: export.json: Direct file download of JSON data from
status.hml.
2.3.2 Configuration Management
The device configuration can be saved and restored in the maintenance area .
The "Config File Export" function can be used to save the current configuration as a
text file. The syntax used in the configuration file corresponds to the commands of the
Telnet console. If the configuration of a device is to be restored from a text file, load
the file with "Upload" and restart the device with "Restart Device".
Saving the configuration should only be carried out in an SSL connection, since it
contains sensitive password information (even if it is encrypted or hashed). For the
same reasons, it is advisable to carefully handle the generated configuration files when
archiving.
Editing the configuration file
It is possible to customize a saved configuration file with a text editor for your own
needs. For example, one scenario would be to use a script language to automate the
creation of many customized versions of a configuration, then equip a large number of
devices with an individualized configuration. Also Upload and restart with CGI com-
mands can be done in scripting languages. With use of the comment sign "#" you can
quickly hide single commands or add personal notes.
If you modify a configuration file manually, it is not always clear which limits are allowed
for parameters. After uploading and restarting, commands with invalid parameters are
ignored. Therefore, the generated configuration includes comments describing the
boundaries of the parameters. Where "range:" refers to a numeric value, and "len:" to a
text parameter. E.g:
email auth set 0 #range: 0..2
email user set "" #len: 0..100
The command "system fabsettings" from the beginning of a generated configuration
file brings the device into the factory state, and then executes the individual commands
that modify the configuration state. It may be desirable to make the changes relative to
the current configuration, and not out of the factory state. Then the "system fabset-
tings" should be removed.
No output of default values
The configuration file contains (with exceptions) only values which differ from the de-
fault. The command "system fabsettings" (go to the factory state) from the beginning of
a generated configuration file should not be removed, otherwise the device can get in-
completely configured.
16

19
Expert PDU Energy 8311 © 2021 GUDE Systems GmbH
Operating
Configuration via Telnet
The configuration files can in principle also be transferred in a Telnet session, but then
the settings are changed during operation, and not completely when restarting, as it
would have been the case with an upload. It can happen that events are triggered at
the same time as the device is configured. One should therefore:
a) disable the function
b) completely parametrize
c) reactivate the function
An example:
email enabled set 0
email sender set "" #len: 0..100
email recipient set "" #len: 0..100
email server set "" #len: 0..100
email port set 25
email security set 0 #range: 0..2
email auth set 0 #range: 0..2
email user set "" #len: 0..100
email passwd hash set "" #len: 0..100
email enabled set 1 #range: 0..1
2.3.3 Bootloader Activation
