A-1 Token Ring Network Option
Token Ring is an alternative network architecture to Ethernet architecture. Token Ring
networks offer a high resistance to failure and are commonly used in large or high-
traffic network installations.
Token Ring networks operate by passing a network token around the electronic equiv-
alent of a ring. The token is a data packet that circulates from one network node to
another, controlling access to the network. In practice, each workstation is connected
to a port on one or more media attachment units (MAUs) which act as network hubs
for the ring connection.
This Appendix describes the Token Ring option and Token Ring cable connections,
and refers you to the remaining configuration that’s required for printing to the
DocuColor.
DocuColor Token Ring option
DocuColor supports Token Ring networks that use IPX and TCP/IP protocols. To use
the DocuColor with a Token Ring network, the Token Ring option must be installed.
This option consists of an enabler board and an Intel Token Ring network interface
card installed in the DocuColor chassis. DocuColor System software that supports the
Token Ring option is standard.
NetWare file servers or other workstations may be directly connected to the Docu-
Color or connected through a router. If they are directly connected, they must also use
a Token Ring adapter and Token Ring cabling. Client computers may be connected to
the NetWare file server with Token Ring or Ethernet cabling.
Connecting Token Ring hardware
The service/support center that installs the DocuColor usually installs the Token Ring
option at the same time, and configures the DocuColor to enable printing.
The DocuColor Token Ring option uses the Intel TokenExpress
™
PRO LAN Adapter
board. Software drivers for the board are included in the DocuColor system software.
