5.0 TROUBLESHOOTING
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.
5.1 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 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.
