another 10Mbps Ethernet or dual-speed hub using a straight-through cable, or an end node using a cross-wired cable.

Please refer to the following chart when deciding on the type of cable necessary for a given connection:

DEVICE	PORT	DEVICE BEING	PORT	CABLE TO USE
	USED	CONNECTED	TYPE

		Hub or	Normal	Crossover (X)
		Switch
	Normal	Switch	Uplink	Straight-Through ()

Router		Server (or PC)		Straight-Through ()

		Hub or	Normal	Straight-Through ()
		Switch
	Uplink	Switch	Uplink	Crossover (X)

		Server (or PC)		Crossover (X)

The figure below shows how to make an Ethernet connection between the router and a network end node.

Important Notes on Ethernet Connections

Observe the following rules when connecting devices with twisted-pair Ethernet cables:

•For both end-node and uplink connections, use only EIA Category 3 or higher- grade twisted-pair data cables with RJ-45 plugs. In almost all cases, only standard straight-through cables are needed.

•Make sure no cable is more than 100 meters (328 feet) long.

•When uplinking two hubs together with a straight-through cable, use an uplink-type jack at one end, and an end-node-type jack at the other.

•If uplinking more than two hubs together, observe the 5-4-3 rule: no signal, in order to go from one end node to another, must ever pass through more than five twisted-pair cables, four repeaters (that is, hubs), and three uplink cables.
