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.
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
).

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