1. Safety instructions: To be read before use!
The ePowerSwitch 8G can only be installed by qualified people with the following installation
and use instructions. The manufacturer disclaims all responsibility in case of a bad utilisation
of the ePowerSwitch 8G and particularly any use with equipments that may cause personal
injury or material damage.
This equipment is designed to be installed on a dedicated circuit that must have a circuit
breaker or fuse protection.
The electrical power socket used to plug the power cord of the ePowerSwitch 8G must be
close to the ePowerSwitch 8G and easily accessible.
Check that the power cords, plugs and sockets are in good condition.
The ePowerSwitch 8G can only be connected to three-wire 230 VAC (50-60Hz) sockets.
Always plug the ePowerSwitch 8G into properly grounded power sockets (two poles plus
ground).
Never exceed 10 Amp total load for each power input.
If you have to replace an external fuse of an ePowerSwitch 8G, never use another type of
fuse than 10A/250V T.
The ePowerSwitch 8G is intended for indoor use only. Do NOT install it in an area where
excessive moisture or heat is present.

ePowerSwitch-8G User's Guide
2. Configuration of the ePowerSwitch 8G
To use the ePowerSwitch 8G on your network you must first configure its network parameters.
Ask your network administrator for the parameters to use.
There are three different methods to configure the ePowerSwitch 8G:
Method 1:
Through a network using the ePowerSwitch Finder Program (on the delivered CD).
It is the simplest and fastest configuration method if you use Windows as operating system. We
suggest that you use this program at least during the first configuration: it allows you to
configure your ePowerSwitch through your local network even if its network parameters (IP
Address, Subnet mask and Port) are not compatible with those of your PC or your local
network.
If you decide to use this method you can directly go to §3 "Configuration using the
ePowerSwitch Finder program".
Method 2:
Through a network using a Web browser (Internet Explorer > 6.0 and Netscape > 6.1).
This method can only be used if the network parameters of the ePowerSwitch (IP Address,
Subnet mask…) have already been configured using either the ePowerSwitch Finder program
(Method 1) or using a Terminal program (Method 3).
For the first configuration you can also change the Network parameters of your PC according to
the default settings of the ePowerSwitch.
Default Network setting of the ePowerSwitch:
IP Address: 192.168.100.100
Mask: 255.255.255.0
Port: 80
If you decide to use this method you can directly go to §4 "Configuration using a Web browser".
Method 3:
Through a RS232 serial interface using a Terminal connection (see §8 "Serial Port pin
configuration" for the configuration of the serial interface connector).
If you use a PC, use the serial cable supplied with the product and a Terminal program such as
HyperTerminal from Microsoft or the program MicroTerminal on the CD.
If you decide to use this method you can directly go to §5 "Configuration using a Terminal
connection".

3. Configuration using the ePowerSwitch Finder program
Remarks:
∇ The ePowerSwitch and the PC used to configure it, have to be connected on the same
segment of the network. The protocol of this program can not be routed so it can not be used
to configure the ePowerSwitch through a WAN or the Internet.
This program does not work if the administrator has deactivated it in the configuration of the
ePowerSwitch (for security reasons for example).
∇
1. Start the ePS-Finder.exe program on the CD-ROM.
The ePowerSwitch Finder window appears.
2. In the tool bar click on the first left button or choose the File/Scan Menu.
The program browses the segment on which is connected your PC and displays the name,
the type, the IP and MAC Address of the connected ePowerSwitch.
3. In the tool bar click on the second left button or choose the File/Configure Menu.
The properties dialog box appears and you can now configure the network parameters. To
configure all other parameters click on the Options button on the bottom of the dialog box.

Explanations about the masks settings
:
Each mask can be an IP address or a range of IP addresses. ∇
∇
∇
∇
∇
∇
Each mask allows you to permit or deny access to the Web server of the ePowerSwitch 8G
to specific addresses or to specific ranges of addresses.
Each mask can be activated or deactivated (without function in this case).
Each IP address consists of a series of four eight-bit numbers. The number 255 is used as a
wildcard, so it replaces all others.
Masks are listed in order of descending priority; so Mask 1 has the highest priority.
Masks have a cumulative effect; high priority masks supersede the effect of lower priority
masks.
Example 1
:
⇒ Deny the access to all IP addresses except 192.168.001.015

7. Ping and Scan method
ePowerSwitch 8G has two methods to check whether an IP equipment (PC, server, router,
Webcam...) is still alive.
Address Pinging
The first method uses the well-known Ping command whereby a request is sent to a specific IP
address. The Ping command, which is an echo request, enables you to determine through an
ICMP protocol (Internet Control Message Protocol) if an IP device is available on the network. If
the system reacts to this request, ePowerSwitch 8G knows that the TCP/IP connection is
established. If the system does not react to one or several requests, ePowerSwitch 8G can
automatically switch off and after a specified delay switch again on the IP equipment (Reboot).
Port Scanning
The second method uses the Port Scan command to test a specific TCP/IP port. In other words,
this command allows you to find out if a specific protocol is available on a server (for example
HTTP, FTP, Telnet, SMTP, POP...). ePowerSwitch 8G simply tries a connection to a specific
server port. If the connection is possible, ePowerSwitch 8G knows that a server program is
running there. If the connection is not possible, ePowerSwitch 8G can automatically switch off
and after a specified delay switch again on the IP equipment (Reboot).
Remarks:
− The Ping and Scan function can be used separately or together.
− The network route between ePowerSwitch 8G and the IP device to supervise should be as
direct as possible, so do not use unnecessary routers and complex wiring between them. A
problem on a router or the wiring could reboot the IP device to supervise.
− Execute several Pings and/or Scans before running the Reboot function. It could be possible
that the IP device to supervise doesn't respond although the IP device is still working.
− Choose a realistic supervision cycle. One second is possible, however it’s not necessary to
overload the network with Ping and Scan requests.
Recommended values:
Interval between Requests: 10 sec or more
Number of unsuccessful Requests before Reboot: 3 or more
Delay before Reboot: 10 sec or more
Delay before first Request after Reboot: 120 sec or more

ePowerSwitch-8G User's Guide
9. Command the state of the power outlets through a Web browser
1. Start your Web browser
Type the IP address of your ePowerSwitch 8G.
The browser displays the authentication dialog box.
2. Enter a user name and its corresponding password.
− If you enter the administrator name
(default value = admin) and the administrator password
(default value = admin) and click OK, you will be able to control all the power outlets and
also to configure all the parameters of the ePowerSwitch 8G.
− If you enter a valid user name
(default value = user1, user2, user3, ..., user8) and the
corresponding user password
(default value = user1, user2, user3, ..., user8) and click OK,
you will only be able to control the power outlet(s) for which you have the rights.
The Power button allows you to switch the corresponding power outlet ON and OFF.
The Restart button allows you to switch OFF the corresponding power outlet. It will then be
automatically switched ON after the delay defined by the administrator during the
configuration (default value is 5 sec).
Under the command button is displayed the status of the IP supervision.
− If the supervision function is deactivated (can be done by the administrator only) the
message «Supervision deactivated» is displayed.
− If the supervision function is activated (can be done by the administrator only) the message
«Supervision activated» is displayed.
Remark: if you switch the socket OFF the supervision function is temporarily deactivated and
the message "Supervision temporarily deactivated" is displayed.

4. On your computer, press <ENTER> until the prompt «>» appears on your screen.
The ePowerSwitch 8G is now in the command mode and is waiting for commands to switch
the power socket.
Remark: the power outlet of the ePowerSwitch 8G can only be controlled if the ePowerSwitch
8G is in the Command mode and NOT in the Configuration mode. If you are in the Configuration
mode type the /RS command to leave this mode. By default, the ePowerSwitch 8G is in
Command mode after a power up.
Use the following command: Px=y
Where x = power outlet number (0 to 8)
0 = all power outlets together
1 = power outlet 1
2 = power outlet 2
3 = power outlet 3
4 = power outlet 4
5 = power outlet 5
6 = power outlet 6
7 = power outlet 7
8 = power outlet 8
Where y = command
0 = switch corresponding power outlet(s) to Off
1 = switch corresponding power outlet(s) to On
r = restart corresponding power outlet(s)
t = toggle corresponding power outlet(s)
