Connecting the Hub To Other Devices

You can connect hubs to other network devices through the dual-speed MDI/ MDI-X RJ-45 port on the front of the hub.

Cable Types and MDI/MDI-X Modes

You can use standard straight through Ethernet cables to connect your hub to PCs, printers, or servers. If you want to connect your BayStack 60-12T/60-24T 10/100 Ethernet Hub to routers, switches, and other hubs you must use a crossover cable unless you set the MDI/MDI-X button to uplink. You can only configure port 1 with the MDI/MDI-X button.

Table 3-1 and Table 3-2 show which cable types and MDI/MDI-X modes to use for various devices when connecting from the BayStack 60-12T 10/100 Ethernet Hub or BayStack 60-24T 10/100 Ethernet Hub, respectively.
