3-2 CHAPTER 3: MAKING FMS 100-TX HUB CONNECTIONS

Hub to Node Once installed, the hub can support up to 12 end node connections. Figure 3-1 shows 11 PCs and one server connected to the RJ-45 ports on the hub’s front panel. You can connect any combination of PCs, servers, and other hubs to the 12 RJ-45 ports. (The thirteenth port permits an additional connection through the transceiver interface module located on the hub’s rear panel. See the section “Installing the Transceiver Interface Modules” in Chapter 2.)

The maximum allowable distance between the hub and a PC, server, or other device is 100 meters of Category 5 UTP cable. The UTP cable used for hub-to-node connections is a straight-through connection. That is, no crossovers should be present. The pin assignments for a straight-through cable are shown in Figure 3-2. Refer to Chapter 4 for cabling details.
