Detect A Network Loop; Resolve A Subnet Conflict To Access The Switch - Netgate Nighthawk S8000 User Manual

Nighthawk S8000 Gaming & Streaming Advanced 8-Port Gigabit Ethernet Switch (GS808E)

Detect a Network Loop

When a network loop occurs, the switch, and possibly the router to which the switch is connected, could
become very sluggish or traffic on your network could come to a halt.
By default, loop detection is enabled on the switch. (You cannot disable it.)
If the switch detects a network loop, all port LEDs for the ports that are being used blink blue fast. This visual
warning allows you to determine which ports are involved in the loop and remove the loop.

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 (or a router that
functions as 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.
To fix this subnet conflict:
1. Disconnect the Ethernet cable between the switch and your network.
2. Unplug the switch's power adapter.
3. Reconnect the Ethernet cable between the switch and your network.
4. Plug the switch's power adapter into an electrical outlet.
The switch powers on. The DHCP server in the network discovers the switch and assigns it an IP address
that is in the correct subnet for the network.
