Reset Button
There is an onboard reset button located between the
power connection and Ethernet connection on the EIM.
Press the Reset button continuously for 5 seconds to
load factory defaults: Use a pointed object, such as a
straightened paper clip or toothpick, to press the reset
button.
This will cause the Ready LED to blink ON and OFF . The
factory defaults will be loaded once the Ready LED stops
blinking (after about 5 seconds). At this point, you should
release the reset button.
It is possible to limit the reset function for the first 60
seconds from initial power-up by accessing the Basic
Settings screen in the webserver configuration mode and
selecting the "Yes" option for Reset Button Protect.
