2. Installation
The ePowerSwitch-M8 (Master) has a built-in Web server, an Ethernet and a serial interface. It
can be used as a stand-alone device to control over IP eight IEC power sockets. The number of
controlled sockets can be extended to 16, 24, 32 or 40 by cascading 1 to 4 ePowerSwitch-S8
(Slave).
The ePowerSwitch-S8 (Slave) has a serial RS232 interface used to control individually its 8
power sockets either through an ePowerSwitch-M8 (Master) or through any device using a
serial RS232 connection (PC, Console server...). By cascading up to 4 ePowerSwitch-S8
(Slave), it is possible to control up to 32 sockets via one serial port.
Connecting ePowerSwitch-M8 (Master)
1. Connect your 10BasteT cable to the RJ-45 network port and to the ePowerSwitch-M8.
If you want to configure the ePowerSwitch-M8 or control its power sockets over a Terminal
connection, connect the supplied serial cable to an available serial port on your PC and to the
serial port of the ePowerSwitch-M8.
2. Plug the 2 power cables into 2 grounded sockets. The A and B LEDs light on to confirm that
power is on and the Pwr LED confirms that the Web server is powered.
3. You can now configure the ePowerSwitch-M8 by following the indications of the paragraph 3
"Configuration of the ePowerSwitch-M8 (Master)" or, if necessary, install the ePowerSwitch-
S8 as indicated hereafter.
Connecting ePowerSwitch-S8 (Slave)
1. Connect the supplied RJ9 link-up cable to the RJ9 Out connector of the Master and to the
RJ9 In connector of the slave.
To cascade several Slaves, link RJ9 Out connector to RJ9 In connector of the next slave.
2. Allocate an address to each Slave by positioning the address selection DIP-switches marked
Slct on the front panel according to the following table.
Remarks
− Unplug the device before changing its DIP switches.
− Do NOT use the same address for two different Slaves.
Slave number DIP-switch 1 DIP-switch 2
1 Off Off
2 On Off
3 Off On
4 On On
Position Off = switch upwards
Position On = switch downwards
Micro-switch 1 is on the left side, micro-switch 2 on the right.
3. Plug the 2 power cables into 2 grounded sockets. The A and B LEDs light on to confirm that
power is on.
