All Magnum Ethernet products are designed to provide reliability and consistently high
performance in all network environments. The installation of a Multilink ML810 Switch is a
straight forward procedure. The operation is also straightforward and is discussed in
Section 4.0 of this ML810 User Guide.
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 Multilink ML810 Switch is not performing as expected, do
not attempt to repair the unit; instead contact your supplier for assistance or contact GE
Customer Support.
1. 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 power is properly attached to each Multilink ML810 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 ML810 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 ML810 Switch and its associated cables are
functioning properly.
5. If the problem continues after completing Step 4 above, contact GE Digital Energy.
Please be prepared to provide the following information.
1. A complete description of the problem, including the following points:
• The nature and duration of the problem;
• Situations when the problem occurs;
• The components involved in the problem;
• Any particular application that, when used, appears to create the problem;
2. An accurate list of GE product model(s) involved, with serial number(s). Include the
date(s) that you purchased the products from your supplier.
3. It is useful to include other network equipment models and related hardware,
including personal computers, workstations, terminals and printers; plus, the various
network media types being used.
