Connecting The 10Base-T/100Base-Tx Ports; Figure 2-5. 10/100 Mb/S Port Connections - Nortel BayStack 450-24T Using Manual

Using the BayStack 450 10/100/1000 Series Switch

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

Connect devices to the 10BASE-T/100BASE-TX (10/100) ports as shown in
Figure 2-5.
The 10/100 switch 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 F, "Connectors and Pin Assignments," for more
information.
By default, all BayStack 450 switch 10/100 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).
