Slide Switch Settings

The ICX-250 is equipped with five external slide switches (four - 3
position, one - 2 position) located on the front panel of the unit. They are
used for T1 and Data Port test and Loopback Transmit / Receive paths.
Each switch is factory set to the off position. The switches should be
checked to be sure positioning hasn't changed during shipment. The
illustration below outlines the location of the slide switches.
Locate the slide switch on the front panel that implements the function
desired. Use the end of a small object or the tip of your finger to change
the switch settings.
