Overview of the TokenSpeed Module

This chapter introduces the 8-port TokenSpeed module and covers the following topics:

•A summary of module functions, capabilities, and features (starting on this page)

•A physical description of the module printed circuit board and the board in relation to the Centillion switch chassis (see page 1-4)

About the TokenSpeed Module

The 8-port TokenSpeed module inserts into one slot of a Centillion 100 or Centillion 50 switch chassis to provide token ring ports and, optionally, an integrated master control processor (MCP). This module replaces earlier module versions that provided only four ports. The TokenSpeed module comes in the following conﬁgurations:

•A TokenSpeed module with eight switched token ring ports with RJ-45 connectors for unshielded twisted pair (UTP) or shielded twisted pair (STP) cable

•A TokenSpeed/MCP module with eight switched token ring ports with RJ-45 connectors for UTP/STP cable and a serial port implemented on a Mini DIN 8 connector

These modules offer identical functional features for token ring connectivity.

In addition to providing token ring connectivity, a TokenSpeed/MCP module also manages the Centillion switch. The MCP port can be used to connect a network management station. One (and only one) MCP module is required for each Centillion chassis; however, an ATMSpeed/MCP or EtherSpeed/MCP module can also be used to meet this requirement.
