1.4 BRIM-E100 OVERVIEW
The BRIM-E100 (shown in Figure 1-1 with an FE-100TX installed)
extends the functionality of a Cabletron Systems MIM or standalone hub
to include 100 Mbps Ethernet bridging capability. The BRIM-E100 is
equipped with one front panel slot that supports a Cabletron Systems
100 Mbps Fast Ethernet Interface Module for network connectivity. The
Modules provide connectivity to a variety of technology types including
100BASE-TX (using RJ45 connectors on twisted pair cable) and
100BASE-FX (using SC connectors on fiber optic cable).

1.5 BRIM-E100 FEATURES
Local Area Network (LAN) Connectivity
The BRIM-E100 uses Cabletron Systems Fast Ethernet Interface Modules
for LAN connectivity. You can easily install these Modules into the
BRIM-E100 for the configuration of your choice.
Auto-Negotiation
The BRIM-E100 when coupled with the FE-100TX module is capable of
auto-negotiation for either 10 Mbps or 100 Mbps operation in full duplex
or standard Ethernet (half duplex) mode. The device at the other end of
the segment must also be capable of auto-negotiation in order to
auto-negotiate full duplex mode. If the device is not capable of
auto-negotiation, the BRIM-E100 senses the speed at which the device
operates and switches to that speed in standard Ethernet mode.
NOTE
Fast Ethernet Interface Module connector and pinout
information is located in Appendix A of this User’s Guide.
