2 TRSM Description TRSM Description The Token Ring Switching Module (TRSM) is designed to add Token Ring (TR) switching functionality to the LANplex 6000, providing the most cost effective solution for introducing segmentation for today's Token Ring networks, while allowing you to prepare for future higher bandwidth requirements such as multimedia applications. The TRSM has eight shielded RJ-45 token ring ports on the front of the module and one FDDI backplane attachm

TRSM Description 3 nonvolatile RAM so they will survive a power loss or system initialization. Source Routed traffic is not forwarded while in this mode. Source Routing (SR) In Source Routing (SR), the packet contains information in the Route Information Field (RIF), which specifies the route the packet should follow in order to reach its destination. Through the process of route discovery, the packet determines various routes available and embeds this information as Ring Numb

8 TRSM Installation WARNING: If the system is powered on when you are installing a module, do not insert any metal objects, such as a screwdriver or a finger with jewelry, in the open slot. This could cause burns or other bodily harm, as well as system damage. 5 Direct the module into the chassis by placing it between the guides of the selected slot and sliding the module until it stops. The module stops sliding when the inject handles make contact with the front of the chassis. Fi
