4 Configuration
4.1 DHCP
After switch-on Expert Power Control NET looks for a DHCP
server and requests an available IP address (for deactivation of that
feature see 2.2).
Please check the IP adress allocated to Expert Power Control
NET 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 to its factory settings.
Activate bootloader mode of Expert Power Control NET and run
GBL_Conf.exe. The program will look automatically for connected
devices and will display their network configuration.

9
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 g
SaveConfig.
Restart the firmware of Expert Power Control NET, so that the
changes will take effect. Now click on Search in order to have the
new network configuration displayed.

You can find more information about configuration of IP ACL in
chapter 3.3 or have a look at http://www.gude.info/wiki.
4.5 SNMP
To get detailed status information of Expert Power Control NET
SNMP can be used. SNMP communicates via UDP (port 161) with
Expert Power Control NET: 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 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 via SNMP.
4.5.1 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.
