6.0 TROUBLESHOOTING
All Magnum Ethernet products are designed to provide reliability and
consistently high performance in all network environments. The installation of Magnum
4K-Series is a straightforward procedure (see INSTALLATION, Section 3); 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 Magnum 4K-Series product is not
performing as expected, do not attempt to repair the unit; instead contact your supplier
for assistance or contact GarrettCom 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 Magnum 4K-
Series 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 Magnum Magnum
4K-Series 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 5 below. If the problem is corrected, the Magnum 4K-Series and its
associated cables are functioning properly.
5. If the problem continues after completing Step 4 above, contact your supplier
of the Magnum 4K-Series unit or if unknown, contact GarrettCom, Inc. by fax,
phone or email ([email protected]) for assistance.
