Token Ring Port Interface Modules
TPIMs are optional features that let you expand your trunk
connections using different media types. TPIMs have embedded
repeaters and retime all data. Cabletron offers a variety of TPIMs for
trunk Ring In or Ring Out connections. Table 1-2 lists each TPIM.
Ring Speed Switch
The Ring Speed Switch lets you select ring speeds of either 4 Mbps or
16 Mbps. The factory default setting is 16 Mbps.
Flash EEPROMs
The TRXI uses Flash EEPROMs that allow you to download new and
updated firmware using Cabletron System’s Remote LANVIEW/
Windows, version 2.3 or later or any device using BOOTP or TFTP
protocols.
LANVIEW LEDs
Cabletron Systems’ LANVIEW LED Status Monitoring and
Diagnostics System is a convenient troubleshooting tool that helps you
diagnose power failures, RI/RO status, cable faults, ring speed, link
problems, and network activity.
Cabletron’s Distributed LAN Monitor
Cabletron Systems’ Distributed LAN Monitor (DLM) is a software
option for the TRXI. DLM provides a method for locally polling and
monitoring devices on a local area network to minimize network
