5.0 TROUBLESHOOTING
All Magnum Ethernet products are designed to provide reliability and consistently
high performance in all network environments. The installation of Magnum DS8016 10/100
Dual Speed Stackable Hubs 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 Magnum DS8016 10/100 Dual Speed Stackable Hub is not
performing as expected, do not attempt to repair the unit; instead contact your supplier for
assistance or contact GarrettCom Customer Support.
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 Magnum DS8016
10/100 Dual Speed Stackable Hubs 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 DS8016
10/100 Dual Speed Stackable Hub 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
DS8016 10/100 Dual Speed Stackable Hubs and its associated cables are
functioning properly.
5. If the problem continues after completing Step 4 above, contact your supplier of
the Magnum DS8016 10/100 Dual Speed Stackable Hubs unit or if unknown,
contact GarrettCom, Inc.by fax, phone or email (support@garrettcom.com) for
assistance.
