Using the BayStack 410-24T 10BASE-T Switch

Connecting 10BASE-T Ports and 10/100 MDA Ports

Connect devices to the 10BASE-T ports and to the (optional) 10/100 MDA ports as shown in Figure 2-5.

The 10BASE-T switch ports and the 10/100 MDA ports are configured with RJ-45 connectors that are wired as MDI-X ports. As in conventional Ethernet repeater hubs, the BayStack 410-24T switch 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 D, “Connectors and Pin Assignments,” for more information.

A standard RJ-45 connection is provided to connect devices to the switch through the 10BASE-T ports and to the 10/100 MDA ports.

Note: The 10/100 MDA 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).
