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 PXES4P 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 PXES4P Series
10/100 Mb/s switch 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 PXES4P
Series Switch and its associated cables are functioning properly.
