5.0 TROUBLESHOOTING
All Magnum Ethernet products are designed to provide reliability and consistently
high performance in all network environments. The installation of Magnum 700X Mini-
Concentrators is a simple procedure (see Section 3.0, INSTALLATION); operation is
very simple 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 700X is not operating as expected, do not attempt to
repair or alter the unit. Contact your supplier (or if unknown, contact Garrett
Communications) for assistance.
5.1 Before Calling for Assistance
1. If difficulty is encountered when installing or operating the Magnum 700X Mini-
Concentrators, refer back to Section 3.0, Installation and Section 4.0, Operation.
Check to make sure that the various other components of the network are 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. Be certain that the AC power cord is plugged into a functioning electrical outlet.
Make sure that the AC power cord is properly plugged into the 700X unit. Use the
PWR LEDs to verify the unit is receiving proper power.
4. If the problem is isolated to a network device other than the Magnum 700X,
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 700X and its associated cables are
functioning properly.
5. If the problem continues after completing Step 4 above, contact your supplier of
the Magnum 700X unit (or if unknown, contact Garrett Communications) by fax
or by phone for assistance.
