3. Making Network Connections

3.1 Network Switched Ports

The following figure illustrates the switched ports provided on the front panel. The switch comes with 24 10/100BASE-TX Fast Ethernet switched ports and two Gigabit Ethernet slots for Gigabit Ethernet modules.

The following table lists the connectors provided on each network ports:

Port #	Standard
Port 1	10/100BASE-TX
Port 2	10/100BASE-TX
	10/100BASE-TX
Port 3-24	10/100BASE-TX
Gigabit slot1	1000BASE-FX
Gigabit slot2	1000BASE-FX

Connector type	Mark
MDI-X RJ-45	1X
MDI-X RJ-45	2X
MDI RJ-45	2
MDI-X RJ-45	3X - 24X
Slot	GIGABIT1
Slot	GIGABIT2

•10/100BASE-TX Fast Ethernet Switched Ports

Each switched port supports one connection to a LAN segments. Each segment is an independent shared network in one collision-domain. The connection can be to either a 10BASE-T or a 100BASE-TX device.

•MDI-X and MDI RJ-45 Connectors

MDI-X jack is labeled [X] normally to indicate the jack is designed with internal crossover function. It allows a connection to an end station using straight-through UTP cable. MDI RJ-45 connector is provided on port for easy uplink via standard straight-through UTP to other device that supports MDI-X RJ-45 connector. The following table shows the pin assignments of MDI-X and MDI RJ-45 connector respec- tively:

PIN#	MDI-X Jacks	MDI Jack
1	Rx+	Tx+
2	Rx-	Tx-
3	Tx+	Rx+
6	Tx-	Rx-
4,5,7,8	NC	NC

•Gigabit Ethernet Slots

Two Gigabit Ethernet slots are provided for Gigabit connections. Each can accommodate one Gigabit Ethernet module. A variety of optional modules is available for selection. Refer to section 3.3 for more information.
