Installing and Operating the Module 3 - 13
❑ 3Com Fault-Tolerant 10BASE-FB Transceiver
Make sure that the transmit fiber at one end always connects to a
receive port at the other end.
Caution: Do not connect this module to an ONline 10BASE-FL
Module or to any other product that is not compatible
with the 10BASE-FB modules. These illegal connections
may cause network failure.
Configuring the Module
The ONline management modules can configure the following settings on
the 10BASE-FB Modules:
❑ Enable and disable each port on the module
❑ Set the ports to independent Ethernet networks within the
concentrator (Port-Switching 10BASE-FB Module)
❑ Set the module to independent Ethernet networks within the
concentrator (10BASE-FB Module)
❑ Set redundancy between two ports on the module or between ports
on another 10BASE-FB Module (using Advanced EMM V4.01 or
higher)
❑ Enable and disable the low light warning
❑ Set the fiber optic transmission power for each port
The following ONline management modules provide network management
capabilities for the ONline System Concentrator and its modules:
❑ Ethernet Management Module V4.01
❑ Token Ring Management Module V3.10
❑ FDDI Management Module V2.00
