Connecting To The Bnc Port - NETGEAR EN516 Installation Manual

Figure 3-3. Cascading multiple hubs in a hierarchical star through the RJ-45
ports
NOTE: Ethernet specifications limit the number of hubs in any
communication path to five hubs, as shown in Figure 3-3. For example,
when PC "A" communicates with PC "B," the communication path goes
from hub 5 to hub 7, passing through hubs 2, 1, and 4.
Figure 3-4 illustrates multiple hubs cascaded in a daisy-chain style.
Figure 3-4. Cascading multiple hubs daisy-chain style through the RJ-45
ports
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.

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:
1. Insert the BNC T-connector on the BNC port of the Model EN516
hub.
2. Connect the coaxial cable that leads from a device on the network to
one of the self-locking ends of the BNC T-connector.
3. Connect the coaxial cable from another device to the remaining end of
the self-locking BNC T-connector. If there are no more devices to be
connected, terminate the connection with the 50 Ohm terminator that
is provided with the product.
4. Proceed to "Completing and Verifying the Installation" on page 3-11.
