|1|| Disconnect the Ethernet cable from the printer's network port and plug this cable into the uplink port on the hub. Note: This takes into account that the printer's Ethernet cable is connected to a switch on the network. If unsure about the connection method:|
- Try connecting the cable to any port adjacent to Port 1 to see whether the Ethernet LED illuminates.
- If the LED does not illuminate, try Port 1, which is often the Uplink port on the hub.
- Also, look for the presence of an uplink switch or button on the hub to check that it is active or turned ON.
|2|| Take one of your Ethernet cables and connect one end to the printer and the other end to an available port on the hub. |
|3|| Disconnect the existing network cable from the computer performing the trace and, using your second extra cable, connect the computer to the hub. Note: You can reconnect the original cable after capturing the network trace. |
|4Observation||There are now three Ethernet cables connected to the hub. Click here for image. |
