Installation
Set the Loop-Back Switch
The loop-back switch is located on the front panel of the Device and is used for
installation and network debugging procedures.
To set the switch, use a small flatblade screwdriver or a
similar device (see the drawing to the right).
CL (Coax loop-back) Enable loop-back on the local coax interface.
-- (Center Position) Normal operation.
FL (Fiber loop-back) Enable loop-back on the local fiber interface.
Note: Three loop-back test scenarios are described in detail on page 10.
