5.0 TROUBLESHOOTING
All Magnum Ethernet products are designed to provide reliability and consistently
high performance in all network environments. The installation of a Magnum DS80F
and DS80C Dual-Speed Hub is a simple procedure (see Section 3.0, INSTALLATION);
operation is easy and is described in Section 4.0, OPERATION.
Should problems develop during installation or operation, this section should help to
locate, identify and correct such problems. Please follow the suggestions listed below prior to
contacting your supplier. However, if you are unsure of any procedure described in this section,
or if the Magnum DS80F or DS80C hub is not operating as expected, do not attempt to repair or
alter the unit. Contact your supplier or if unknown, contact GarrettCom Customer Support.

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.
