4 Configuration
4.1 DHCP
After switch-on Expert Power Control NET 8x 8210 / 8211 looks for a DHCP server and requests an available IP address .
Please check the IP address allocated to Expert Power Control NET 8x 8210 / 8211 in the DHCP server settings to make
sure that the same address is used at every reboot.
4.2 Network settings with GBL_Conf
For changing the network properties manually, the program GBL_Conf.exe is required. This tool is available for free on our
website www.gude.info.
Furthermore GBL_Conf.exe enables you to install firmware updates and to reset Expert Power Control NET 8x 8210 / 8211
to its factory settings.
Activate bootloader mode of Expert Power Control NET 8x 8210 / 8211 and run GBL_Conf.exe. The program will look
automatically for connected devices and will display their network configuration.
If the displayed IP address accords with the factory settings (192.168.0.2), there is either no DHCP server available in the
network or no free IP address could be allocated.
Enter a free IP address and the according netmask in the entry mask, then save these changes by clicking on Program
Device SaveConfig.

4.3 Configuration via webinterface
Go to the website of Expert Power Control NET 8x 8210 / 8211. Enter the IP address of Expert Power Control NET 8x
8210 / 8211 into the address line of your internet browser:
http://”IP address of Expert Power Control NET 8x 8210 / 8211”/
and press LOGIN.
To enter the configuration menu, click on „Configuration“ on the upper left side of the screen.
4.3.1 Configuration - Power Ports
4.3.1.1 Label
A name with a maximum of 15 characters can be entered here for each Power Port.

11
Expert Power Control NET 8x 8210 / 8211 Configuration
4.3.1.2 After power-up switch
The Power Port’s switching state after a power-on of the device can be defined here (on, off, remember last state).
4.3.1.3 If switching on after power-up, wait ...
A switching delay of a Power Port can be defined here that is applied after switch on of the device. The delay can last up to
8191 seconds.
4.3.1.4 After turning off, wait ...
While this function is enabled, the Power Port will reactive after the stated time, when it got switched off.
4.3.1.5 Watchdog
While using the watchdog, electrical devices can be observed. The watchdog sends ICMP-pings or TCP-pings to the device. If
these pings were not answered, during a defined delay (time or pings), the power port will reset. The watchdog function allows
to restart e.g. crashed servers or NAS systems.
You can check the watchdog function and other imformation inside of the switching menu. There are different colors:
Green text: Watchdog is active and receives ping replies
Orange text: Watchdog is activating at the moment, waiting for first ping reply
Red text: Watchdog is active and does not receive ping replies any longer
When watchdog is activating it waits of a first ping reply. During this time, the information is written as an orange text. After the
receive of the first ping reply, it switches to active, written in green letters.
When a watchdog reset a power port, the watchdog again waits for a first ping reply, as stated above.
4.3.1.5.1 Enable Watchdog
Here you can activate the watchdog for this power port.
4.3.1.5.2 Watchdog type

Expert Power Control NET 8x 8210 / 8211 Configuration
4.3.3 Configuration - IP ACL
IP Access Control List (IP ACL) acts as an IP filter for your Expert Power Control NET 8x 8210 / 8211. Wether it is active
hosts and subnets only can contact Expert Power Control NET 8x 8210 / 8211, if their IP adresses are stated in this IP ACL.
e.g.: „http://192.168.0.1“ or „http://192.168.0.1/24“
If you locked yourself out by mistake, please activate the bootloader mode of Expert Power Control NET 8x 8210 / 8211,
start Gbl_Conf.exe and deactivate IP ACL.
You can find more information about configuration of IP ACL or have a look at http://www.gude.info/wiki.

Here you can enter the HTTP port number, if necessary. Possible numbers are 1 ... 65534 (standard: 80). To get access to
Expert Power Control NET 8x 8210 / 8211, you have to enter the port number behind the IP address of Expert Power
Control NET 8x 8210 / 8211, e.g.: http://192.168.0.2:1720
All changes need a restart of the firmware to get valid.
4.3.4.2 Require HTTP Password
Password protected access can be activated here. In this case, a user and an admin password have to be defined.
Passwords have a maximum lengths of 15 characters.
Administrators are authorized to switch all ports and to modify the settings of Expert Power Control NET 8x 8210 / 8211 and
of all ports. The username of the admin is “admin”.
Users are authorized to switch all ports but are not allowed to modify the settings of neither Expert Power Control NET 8x
8210 / 8211 nor the ports. The username of the user is “user”.
If you have forgotten your password, activate the bootloader mode of Expert Power Control NET 8x 8210 / 8211, start GBL-
Conf.exe and deactivate the password request.
All changes need a restart of the firmware to get valid.

SNMP and Syslog.

15
Expert Power Control NET 8x 8210 / 8211 Configuration
4.3.5.3 Min. Temperature
Here you can define the minimum temperature, if the sensor measures this temperature the device will generate an alert via
SNMP and Syslog.
4.3.6 Configuration - SNMP
4.3.6.1 SNMP
To get detailed status information of Expert Power Control NET 8x 8210 / 8211 SNMP can be used. SNMP communicates
via UDP (port 161) with Expert Power Control NET 8x 8210 / 8211: You can use SNMP to switch the power ports as well.
Supported SNMP commands:
- SNMPGET: request status information
- SNMPGETNEXT: request the next status information
- SNMPSET: Expert Power Control NET 8x 8210 / 8211 request change of status
You will need a Network Management System, e.g. HP-Open View, OpenNMS, Nagios etc., or the command line tools of
NET-SNMP to request information of Expert Power Control NET 8x 8210 / 8211 via SNMP.
4.3.6.1.1 SNMP-communities
SNMP authentifies requests by so called communities.
The public community has to be added to SNMP-read-requests and the private community to SNMP write requests. You can
see the SNMP communites like read/write passwords. SNMP v1 and v2 transmit the communities without encryption.
Therefore it is simple to spy out these communities. We recommend to use a DMZ or IP ACL.
4.3.6.1.2 MIB
All information, that can be requested or changed, the so called „Managed Objects“, are descripted in „Management
Information Bases“ (MIBs).
There are three MIBs, which can be requested from Expert Power Control NET 8x 8210 / 8211:
„system“, „interface“ and „powerports“
„system“ and „interface“ are standardised MIBs (MIB-II).
„powerports“ (GUDEADS-EPC-MIB::gadsEPC) was created especially for Expert Power Control NET 8x 8210 / 8211.
At least, there are so called Object Identifiers (OID) subordinated to those three structures. An OID describes the location of
an information inside a MIB.
4.3.6.1.3 SNMP-traps
SNMP-Traps are system messages, sent via SNMP-protocol to different clients. On following events, Expert Power Control
NET 8x 8210 / 8211 will dispatch a SNMP-Trap:
Switching of the Power Ports
Min/Max-Alerts from the sensors
You can find more information about configuration of SNMP at http://www.gude.info/wiki.

http://www.gude.info/wiki or ask our support team.
4.3.8 Configuration - Syslog
Syslog messages are simple text messages transmitted to a syslog server using UDP.
Linux OS regularly have a syslog daemon installed, e.g. syslog-ng. For Windows there are some freeware tools available.
On following events, Expert Power Control NET 8x 8210 / 8211 will send a syslog message:
- Booting up

www.gude.info/wiki
5.3 Switching via serial interface
Alternatively to the Ethernet interface, the Power Ports of Expert Power Control NET 8x 8210 / 8211 can be switched
through its serial interface. It only requires a terminal program like HyperTerminal, a program provided under Windows for free
(to be found under Programs -> Accessories -> Communication).
Connect your PC with Expert Power Control NET 8x 8210 / 8211 with the PS2-RS232 adaptor cable and plug the device
into a outlet. Now you can turn on Expert Power Control NET 8x 8210 / 8211. The boot process lasts a few seconds longer
than by Ethernet.
You can access Expert Power Control NET 8x 8210 / 8211 through the terminal program as soon as the status LED shines
green. Choose the COM port that is connected to Expert Power Control NET 8x 8210 / 8211 and enter the following values
for the serial interface:
Bits per seconds
115200
Data bits
