NETGEAR Managed Stackable Switch M5300 Series Additional Troubleshooting Suggestions If the suggestions in Table 3 on page 22 do not solve 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 connections, 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-nNegotiation: If the device at the other end of the link supports auto-negotiation, the copper 10/100/1000 Mbps ports negotiate the correct duplex mode and speed. If the device does not support auto-negotiation, the switch determines only the speed correctly, and the duplex mode defaults to half-duplex. If the attached device supports auto-negotiation, the fiber gigabit ports negotiate speed, duplex mode, and flow control. Troubleshooting 23
