Using the BayStack 450 10/100/1000 Series Switch

Connecting the 10BASE-T/100BASE-TX Ports

Connect devices to the 10BASE-T/100BASE-TX ports as shown in Figure 2-5.

The BayStack 450 switch 10BASE-T/100BASE-TX ports are configured with RJ-45 connectors that are wired as MDI-X ports. As in conventional Ethernet repeater hubs, these ports connect via straight-through cables to the network interface card (NIC) in a node or server. When connecting to an Ethernet hub or to another switch, you must use a crossover cable. See Appendix E, “Connectors and Pin Assignments,” for more information.

By default, all BayStack 450 switch 10BASE-T/100BASE-TX switch ports are set with autonegotiation enabled. This feature allows any port to match the best service provided by the connected station, up to 100 Mb/s in full-duplex mode.

Note: The 10BASE-T/100BASE-TX ports must use Category 5 UTP cable to accommodate the 100BASE-TX functionality.

To connect the RJ-45 port cables, insert the cable plug into the appropriate port connector until the release tab snaps into the locked position (Figure 2-5).
