Refer to the Hub manufacturer’s manual for specific cabling information 
for connecting workstations to the Hub.
To connect the Token Ring module to a UTP Hub, attach one end of a 
UTP cable to the Token Ring module’s RJ45 connector and connect the 
other end with the appropriate connector to any port 
 
except
 
 the Ring In or 
Ring Out ports on a UTP Hub. The Ring In/Ring Out ports are used for 
interconnecting Hubs. Refer to the example shown in Figure 2-1.

When using Shielded Twisted Pair cabling, refer to the following (this 
assumes patch cables that are no longer than 8 feet or 2.4 meters):
 
a. To assure compatibility with future LANs, the longest lobe should be limited to 
100 meters.
