Token Ring Card
Introduction This card provides two 4/16Mbps token ring ports for the 7300 platform. This card
conforms to the IEEE802.5 standard for token ring. The 7300 supports one token
ring card per box. Each port is independently operated at either 4 or 16Mbps. Either
a UTP or STP cable can be used by connecting the cable to the appropriate port. The
cable type is automatically selected. A standard RJ45 connector will be provided for
UTP and a standard DB9 connector will be provided to STP cables. Figure 2-27
shows the front of the Token Ring card.
Warning
Attaching a CTP cable to a UTP port damages the token ring card.
