6.0 TROUBLESHOOTING
All DFG48000 Ethernet products are designed to provide reliability and consistently high
performance in all network environments. The installation of a DFG48000 Switch is a
straightforward procedure (see INSTALLATION, Section 2.6); the operation is also straightforward
and is discussed in Section 4. Should problems develop during installation or operation, this
section is intended to help locate, identify and correct these types of problems. Please follow the
suggestions listed below prior to contacting your supplier. However, if you are unsure of the
procedures described in this section or if the DFG48000 Switch is not performing as expected, do
not attempt to repair the unit; instead contact your supplier for assistance or contact Dante
Security Customer Support.
6.1 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 DFG48000 Switch unit. Be
certain that each AC power cord is plugged into a functioning electrical outlet. Use the PWR
LEDs to verify each unit is receiving power.
4. If the problem is isolated to a network device other than the DFG48000 Switch product, it is
recommended that the problem device be replaced with a known good device. Verify whether
or not the problem is corrected. If not, go to Step 5 below. If the problem is corrected, the
DFG48000 Switch and its associated cables are functioning properly.
5. If the problem continues after completing Step 4 above, contact your supplier of the DFG48000
Switch unit or if unknown, contact Dante Security, Inc. by fax, phone or email
for assistance.
6.2 When Calling for Assistance
Please be prepared to provide the following information.
1. A complete description of the problem, including the following points:
a. The nature and duration of the problem;
b. Situations when the problem occurs;
c. The components involved in the problem;
d. Any particular application that, when used, appears to create the problem;
2. An accurate list of Dante Security product model(s) involved, with serial number(s). Include the
date(s) that you purchased the products from your supplier.
3. It is useful to include other network equipment models and related hardware, including
personal computers, workstations, terminals and printers; plus, the various network media
types being used.
4. A record of changes that have been made to your network configuration prior to the occurrence
of the problem. Any changes to system administration procedures should all be noted in this
record.
