3.2 Network conguration by GBL_Conf.exe
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 rmware up-
dates and to reset EPC NET 8x to its factory settings (see 5.2).
Activate bootloader mode of EPC NET 8x and run GBL_
Conf.exe (see 5.1). The program will look automatically for con-
nected devices and will display their network conguration.
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
gSaveCong.
Restart EPC NET 8x by
switching it off and on again,
so that the changes will take
effect. Now click on Search
in order to have the new
network conguration dis-
played.
3. Conguration
3.1 Automatic conguration by DHCP
After switch-on EPC NET 8x looks for a DHCP server and re-
quests an available IP address (for deactivation of that feature
see 2.2).
Please check the IP adress allocated to EPC NET 8x in the
DHCP server settings to make sure that the same address is
used at every reboot.

3.4 IP Access Control List
IP Access Control List (IP ACL) acts as an IP lter for your EPC
NET 8x. Wether it is active hosts and subnets only can contact
EPC NET 8x, 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 boot-
loader mode of EPC NET 8x, start Gbl_Conf.exe and deactivate
IP ACL.
You can nd more information about conguration of IP ACL in
chapter 3.3 or have a look at http://www.gude.info/wiki.
3.5 SNMP
To get detailed status information of EPC NET 8x SNMP can be
used. SNMP communicates via UDP (port 161) with EPC NET
8x: 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 : EPC NET 8x 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 EPC NET 8x via SNMP.
SNMP Communities
SNMP authenties 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.

3.6 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, EPC NET 8x will send a syslog message:
- Booting up
- Activation/deactivation of syslog
- Switching of Power Ports
You can nd more information about conguration of Syslog in
chapter 3.3 or have a look at http://www.gude.info/wiki.
MIBs
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 EPC NET
8x:
„system“, „interface“ and „powerports“
„system“ and „interface“ are standardised MIBs (MIB-II).
„powerports“ (GUDEADS-EPC-MIB::gadsEPC) was created
especially for EPC NET 8x.
At least, there are so called Object Identiers (OID) subordina-
ted to those three structures. An OID describes the location of
an information inside a MIB.
SNMP-Traps
SNMP-Traps are system messages, sent via SNMP-protocol to
different clients. On following events, Expert Power Control NET
8x will dispatch a SNMP-Trap:
- Switching of the Power Ports
You can nd more information about conguration of SNMP in

4.3 Switching via Serial Interface
Alternatively to the Ethernet interface, the Power Ports of EPC
NET 8x can be switched through its serial interface. It only re-
quires a terminal program like HyperTerminal, a program pro-
vided under Windows for free (to be found under Programs→
Accessories→Communication).
Connect your PC with EPC NET 8x by a 9-pole serial cable
(RS232) and plug the device into a outlet. Now you can turn on
EPC NET 8x. The boot process lasts a few seconds longer than
by Ethernet.
You can access EPC NET 8x through the terminal program as
soon as the status LED shines green. Choose the COM port that
is connected to EPC NET 8x and enter the following values for
the serial interface:
If you do not use HyperTerminal, please make sure that the
terminal program supports VT100 commands.
After having it connected successfully, EPC NET 8x answers as
shown in gure 15. Press Enter for login.
