GS700TPS Smart Switch Table A-1. Troubleshooting Chart Symptom Cause Solution ACT LED is flashing continuously on all connected ports and the network is disabled. A network loop (redundant path) has been created. Break the loop by ensuring that there is only one path from any networked device to any other networked device. A unit is linked to a stack, but does not join the stack. The stacking ports of the new unit are configured differently from the stack, or the unit is configured as a stand-alone unit. Remove the unit from the stack. If the stack links are copper links, push the "Restore to Default" button. If the stack links are combo links, use the Web Management to configure the unit as a stackable unit, with combo links used as the stacking ports. Additional Troubleshooting Suggestions If the suggestions in Troubleshooting Chart do not resolve the problem, refer to the troubleshooting suggestions in this section. Network Adapter Cards Ensure the network adapter cards installed in the PCs are functioning correctly and the latest software driver has been installed. Configuration If problems occur after altering the network configuration, restore the original connections and determine the problem by implementing the new changes, one step at a time. Ensure that cable distances, repeater limits, and other physical aspects of the installation do not exceed the Ethernet limitations. Switch Integrity If required, verify the integrity of the switch by resetting the switch. To reset the switch, disconnect the AC power from the switch and then reconnect AC source.
