Installation and User Guide (08/98)

 

 

5.0TROUBLESHOOTING

All Magnum Ethernet products are designed to provide reliability and consistently high performance in all network environments. The installation of Magnum 508 Switching Hubs is a straightforward procedure (see Sections 3); the operation is also straightforward and is discussed in Sections 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 508 product is not performing as expected, do not attempt to repair the unit; instead contact your supplier for assistance or contact Garrett Communications Customer Support.

5.1Before 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 inter-operable.

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 500-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 500- Series 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 Magnum 500-Series Switching Hub and its associated cables are functioning properly.

5.If the problem continues after completing Step 4 above, contact your supplier of the Magnum 500-Series unit (or if unknown, contact Garrett Communications) by fax, phone or email for assistance.
