5.0 TROUBLESHOOTING

All Magnum Ethernet products are designed to provide reliability and consistently

high performance in all network environments. The installation of Magnum ST80 Stackable

Personal Hub 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 ST80 Stackable Personal 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

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.

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.)

Make sure that an AC power cord is properly attached to each Magnum ST80

Stackable Personal Hub 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.

If the problem is isolated to a network device other than the Magnum ST80

Stackable Personal 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

ST80 Stackable Personal Hub and its associated cables are functioning properly.

If the problem continues after completing Step 4 above, contact your supplier of

the Magnum ST80 Stackable Personal Hub unit or if unknown, contact

GarrettCom, Inc.by fax, phone or email (

support@garrettcom.com

) for assistance.
