interface via the RJ–45 connector on the back panel. Always use CAT–5d or higher
class cables for reliability reasons. The LAN interface is equipped with the Auto MDIX
function for automatic detection of a straight or cross–over cable.
The LAN interface can also be used for the
active network elements or injectors meeting the IEEE 802.3af standard.
Note: With PoE, the integrated amplifier power output is limited to 8W. To utilise the
maximum power output of the amplifier, feed
DC/2A power supply.

LAN interface. In case this option is unavailable, use a 12V DC/2A (Part No. 914102E)
power supply, or another power supply on condition that you keep the nominal values
included in the Electric Parameters subsection.
Connect the 12V DC power supply either to the back panel supply connector marked
DC IN, or terminals marked DC IN + and DC IN –.
Warning If you use an adapter other than the recommended one, do not exceed the
nominal supply voltage value of 12V. Also make sure that the supply voltage polarity is
correct. Exceeding nominal values and/or incorrect connection may lead to irreversible
damage of the equipment.

2N NetSpeaker Configuration
In some cases, it may be useful to reset the
RESET button on the back panel. Do this, for example, if
respond, which may be caused by incorrect LAN settings, LAN configuration changes,
forgotten password and so on.
Resetting Procedure:
1. Use a thin rigid tool (a toothpick or a paperclip) to press the RESET button on the
back panel.
2. Keep the RESET button pressed as long as the front panel LED is shining green
(approx. for 10s).
3. Release the button as soon as the LED starts flashing yellow quickly. It means
that the configuration in the internal FLASH memory is being deleted.
This operation takes about 50s. Do not disconnect the device from power supply during
this period.
