Managed Layer 2+ Stackable Switches FSM7226RS and FSM7250RS Hardware Installation Guide Additional Troubleshooting Suggestions If the suggestions in Table 3-1 on page 3-1 do not resolve your problem, refer to the troubleshooting suggestions in this section. • Network Adapter Cards Make sure that the network adapter cards installed in the PCs are in working condition and the software driver has been installed. • Configuration If problems occur after you change the network configuration, restore the original connections. Then find the problem by making the changes, one step at a time. Make sure that cable distances, repeater limits, and other physical aspects of the installation do not exceed the Ethernet limitations. • Switch Integrity You can verify the integrity of the switch by resetting the switch. To reset the switch, use the Tools> Reset command or remove AC power from the switch and then reapply AC power. If the problem continues, contact NETGEAR technical support. • Auto-Negotiation The copper 10/100/1000 Mbps ports negotiate the correct duplex mode and speed if the device at the other end of the link supports auto-negotiation. If the device does not support autonegotiation, the switch only determines the speed correctly and the duplex mode defaults to half-duplex. The fiber gigabit ports negotiate speed, duplex mode, and flow control, provided that the attached device supports auto-negotiation. 3-2 Troubleshooting v1.0, October 2008
