1 - 2 ONline Ethernet 10BASE-FB Module Installation and Operation Guide
10BASE-FB Module Descriptions
The ONline Ethernet Port-Switching 10BASE-FB Mo dule is a 2- or 4-port,
Ethernet fiber module designed for 3Com ONline System Concentrators.
The ONline Ethernet 10BASE-FB Module is a 4-port, Ethe rnet fiber module
also designed for 3Com ONline System Conce ntrators.
The ONline Ethernet Port-Switching 10BASE-FB Module (Model Number
5104M-FBP) is functionally identical to the O Nline Ethernet 10BASE-FB
Module (Model Number 5104M- FB1) except for the Port-Switching
Module's ability to set each port to an indep endent backplane network in
the concentrator.
The 5104M-FB1 is module-switching only. Y ou can update the 10BASE-FB
Module to a port-switching mod ule by installing the ONline Ethernet
10BASE-FB Upgrade Kit.
The 10BASE-FB Modules provide:
❑Fiber backbone connectivity for Ethernet local area networks
❑Direct fiber to-the-desk connectivity
You can directly connect the 10BAS E-FB Modules to any other ONline fiber
module as well as all of the produc ts in the 3Com 10BASE-FB family,
including the:
❑3Com 10BASE-FB Star Coupler
❑3Com 10BASE-FB Fiber Transceiver
❑3Com Fault-Tolerant 10BASE-FB Tran sceiver
The 10BASE-FB Modul es:
❑Provide up to 4.0 kilometers dis tance between any two concentrators
❑Support network diameters up to 4.2 kilome ters
❑Contain built-in link redundanc y for fault tolerance
