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. If the fiber port does not link up while connecting to other device, do a quick Loop test to test the
fiber transceiver is functional or not. Use a short patch cable of fiber and connect one end of cable
to transmit and other end of receive to the fiber port transceiver. If the Link Led turns solid green,
then the fiber port is functional and working.
4. Make sure that an AC power cord is properly attached to each Dante Security DFG48044X Series
unit. Be certain that the AC power cord is plugged into a functioning and appropriate electrical
outlet. Use the PWR LEDs to verify each unit is receiving power.
5. If the problem is isolated to a network device other than the DFG48044X Series 10/100 Mb/s switch
product, it is recommended that the problem device is replaced with a known good device. Verify
whether or not the problem is corrected. If not, go to Step 6 below. If the problem is corrected, the
DFG48044X Series Switch and its associated cables are functioning properly.
6. If the problem continues after completing Step 5 above, contact your supplier
of the DFG48044X Series 10/100 Mb/s switch unit or if unknown, contact Dante Security, Inc by fax, phone
or email –
