Magnum 4K220 Switches Installation and User Guide
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
4K220 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 4K220
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 4K220 Series
Switches
and its associated cables are functioning properly.
5.
If the problem continues after completing Step 4 above, contact your supplier
of the Magnum 4K220 unit or if unknown, contact GarrettCom, Inc.by fax,
phone or email (support@garrettcom.com) for assistance.
