Migrating from Serial and Token Ring to Ethernet
The FEP-4600 supports SNA communication (LLC) through any of the Ethernet
interfaces. This may allow you to easily migrate from Token Ring or SDLC
environments to Ethernet environments, especially if you are currently using a router to
provide DLSw communications to remote sites.
True Migration Strategies
The FEP-4600 can be configured and operated in parallel with existing 37x5 FEPs to
provide a safe means to migrate at your own pace, moving individual connections to the
new platform without having to move every connection at once.
