performing as expected, do not attempt to repair the unit; instead contact your supplier for

5.1 Before Calling for Assistance
1. If difficulty is encountered when installing or operating the unit, refer back
to the Installation Section of the applicable chapter of this manual. Also
check to make sure that the various components of the network are
interoperable.
2. Check the cables and connectors to ensure that they have been properly
connected and the cables/wires have not been crimped or in some way
impaired during installation. (About 90% of network downtime can be
attributed to wiring and connector problems.)
3. Make sure that an AC power cord is properly attached to each
LBH101A Series unit. Be certain that the AC power cord is plugged into a
functioning electrical outlet. Use the PWR LEDs to verify each unit is
receiving power.
