Restore Factory Defaults Button

Press and hold the Reset button for 5 seconds to load the factory default
settings. Use a pointed object, such as a straightened paper clip or
toothpick, to depress the Reset button. This will cause the STATE LED to
blink once a second. After depressing the button for 5 continuous seconds,
the STATE LED will start to blink rapidly. This indicates that factory default
settings have been loaded and you can release the reset button.
NOTE Do NOT power off the Ethernet extender when loading default

DIP Switches Settings

The IEX-402-SHDSL series provides 4 hardware DIP switches for quick
configurations, based on terminal type (CO/CPE), DSL signal
measurement type (Speed/SNR), communication media type (ANNEX
A/ANNEX B) and data rate mode (STD/Turbo).
NOTE Reboot the system after changing any of the DIP switch
configurations.
Auto Negotiation Mode
The SHDSL Ethernet extenders operate in pairs. One of the units needs to
be configured as a CO and the other as a CPE. By factory default,
IEX-402-SHDSL are configured as COs.
To make configuration easier, the IEX-402-SHDSL supports CO/CPE auto
negotiation. Enable the factory setting CO mode on the CO/CPE DIP
switch for both connected extenders, and the system will auto negotiate
and assign CPE to one of the devices in each pair.
