CH A P T E R 1 Intel Express 550T Routing Switch

RJ-45 connector pin	The RJ-45 ports on the front of the switch have the following pin as-
assignments	signments:
	Pin number	Function
	1	RX+
	2	RX-
	3	TX+
	6	TX-
Connecting a device to	To connect a workstation compatible with IEEE 802.3 (Ethernet Ver-
the RJ-45 ports	sion 1.0 and 2.0) or a fast access device (such as a server) to the
	switch’s RJ-45 ports using UTP cable (Category 5):
	1 Make sure that the device has a 100Mbps (100Base-FX or 10/
	100Base-TX) network interface card installed.
	If not, use your network interface card’s documentation to
	install and configure it correctly.
	2 If your workstation is fitted with an RJ-45 interface then there is
	no problem. However, it is possible to attach to other connector
	types using an appropriate adapter. For example, use a UTP/
	10Base-FL adapter for fiber connections
	3 Connect one end of the UTP cable to an RJ-45 port on the
	switch.
	According to IEEE 802.3, the cable length must not exceed 100
	meters (approximately 325 feet).
	4 Connect the other end to the 100Base-TX connection on the
	device.
Cable for the Console Port	If you connect a PC (via the Console Port), then use a null-modem ca-
	ble.

	Connecting the Power
Introduction	After connecting the devices to the switch, connect the power cable.
	There are certain practical and safety considerations to be made be-
	fore powering the switch on.
