Connecting to the BNC Port

The BNC port at the rear panel of the Model EN516 hub is used for connecting to a thin coaxial

segment. You can connect servers, workstations, or other devices to the BNC port or several Model

EN516 hubs as shown in Figure 3-5. By using the BNC port for cascading, you treat each

connected hub as just another node on the coaxial segment.

When using the BNC interface, follow these steps:

Insert the BNC T-connector on the BNC port of the Model EN516 hub.

Connect the coaxial cable that leads from a device on the network to one of the

self-locking ends of the BNC T-connector.

Note:

Each twisted pair cable between two hubs is counted as one network segment.

When cascading hubs daisy-chain style through the twisted pair cable, stay within

Ethernet speciﬁcations and make sure the total hub count does not exceed ﬁve hubs.
