Resolve A Subnet Conflict To Access The Switch; Poe Troubleshooting Suggestions - NETGEAR GS105Ev2 User Manual

Resolve a Subnet Conflict to Access the
Switch
If you power on the switch before you connect it to a network that includes a DHCP
server, the switch uses its own default IP address of 192.168.0.239. This subnet might
be different from the subnet used in your network. You might see the following message
if you try to use the ProSAFE Plus Utility to access the switch:
The switch and manager IP address are not in the same subnet.
To resolve this subnet conflict:
1. Disconnect the Ethernet cable between the switch and your network.
2. Shut down power to the switch.
3. Reconnect the Ethernet cable between the switch and your network.
4. Reapply power to the switch.
The switch powers on. The network DHCP server discovers the switch and assigns
it an IP address that is in the correct subnet for the network.

PoE Troubleshooting Suggestions

Here are some tips for correcting Power over Ethernet (PoE) problems that might occur
on switches that support PoE:
• Make sure that the PoE Max LED is off. If the PoE Max LED is solid amber, disconnect
one or more PoE devices to prevent PoE oversubscription.
• Make sure that the Ethernet cables are plugged in correctly. For each powered
device (PD) that is connected to the switch, the associated PoE port LED on the switch
lights solid green. If the associated PoE port LED lights solid amber, a PoE fault
occurred and PoE halted because of one of the conditions that are listed in the
following table.
