10/100 Mbps Ethernet via the RJ-45 Connector

Use a straight-through cable on the 10/100 Mbps ports if the device attached to the port is a computer. If the device is a switch, hub, or router, use a crossover cable. See the figure below for cabling details. You can use a straight-through cable with a switch, hub, or router if it has an uplink enable/disable switch that you can set.
