3. Conguration
3.1 Automatic conguration by DHCP
After switch-on EPC NET 24x 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 24x in the
DHCP server settings to make sure that the same address is
used at every reboot.
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
updates and to reset EPC NET 24x to its factory settings (see
5.2).
Activate bootloader mode of EPC NET 24x 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 24x
by switching it off and on
again, so that the chang-
es will take effect. Now
click on Search in order
to have the new network
conguration displayed.

Password protected access can be activated here. In this case,
a user and an admin password have to be dened. Passwords
have a maximum lengths of 15 characters.
Administrators are authorized to switch all ports and to modify
the settings of EPC NET 24x 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
EPC NET 24x nor the ports.
The username of the user is
“user”.
If you have forgotten your
password, activate the boot-
loader mode of EPC NET 24x,
start GBL_Conf.exe and deac-
tivate the password request.
All changes need a restart of
the rmware to get valid.

3.4 IP Access Control List
IP Access Control List (IP ACL) acts as an IP lter for your EPC
NET 24x. Wether it is active hosts and subnets only can contact
EPC NET 24x, 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 24x, start Gbl_Conf.exe and deacti-
vate IP ACL.
You can nd more information about conguration of IP ACL in

3.5 SNMP
To get detailed status information of EPC NET 24x SNMP can be
used. SNMP communicates via UDP (port 161) with EPC NET
24x: 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 24x request change of sta-
tus
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 24x 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.
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 24x:
„system“, „interface“ and „powerports“
„system“ and „interface“ are standardised MIBs (MIB-II).
„powerports“ (GUDEADS-EPC-MIB::gadsEPC) was created
especially for EPC NET 24x.
At least, there are so called Object Identiers (OID) subordi-
nated to those three structures. An OID describes the location of
an information inside a MIB.

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 24x will send a syslog
message:
- Booting up
- Activation/deactivation of syslog
- Switching of Power Ports
- Changes of the fuses
You can nd more information about conguration of Syslog in
chapter 3.3 or have a look at http://www.gude.info/wiki.
SNMP-Traps
SNMP-Traps are system messages, sent via SNMP-protocol to
different clients. On following events, EPC NET 24x will dispatch
a SNMP-Trap:
- Switching of the Power Ports
- Changes of the fuses
You can nd more information about conguration of SNMP in
Chapter 3.3 or have a look at http://www.gude.info/wiki.
