GE ML1200 instruction manual Before Calling for Assistance

CHAPTER 4: OPERATION OPERATION

described in this section or if the Multilink ML1200 Switch is not performing as expected, do not attempt to repair the unit; instead contact your supplier for assistance or contact GE Multilin Customer Support.

4.2.3Before 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 DC power is properly attached to each Multilink ML1200 Switch unit. Use the PWR LEDs to verify each unit is receiving power.

4.If the problem is isolated to a network device other than the Multilink ML1200 Switch 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 Multilink ML1200 Switch and its associated cables are functioning properly.

5.If the problem continues after completing Step 4 above, contact your supplier of the Multilink ML1200 Switch unit or if unknown, contact GE Multilin for assistance.
