INTRODUCTION
Page 1-3
You can upgrade the TRXI-22 and TRXI-42 to twenty-four ports using
a twelve port upgrade kit available from Cabletron Systems
(Cabletron Part Number TRXI-24-UGKIT or TRXI-44-UGKIT).
The TRXI provides two additional ports for Ring In and Ring Out
connections. These ports support Cabletron’s Token Ring Port
Interface Modules (TPIMs). TPIMs provide full repeater functionality.
They are not included with the TRXI, but can be ordered separately
from Cabletron. Table 1-2 lists each TPIM.
1.4 TRXI FEATURES
Local Management
Local Management provides the tools to manage the TRXI and all of
its attached segments. You access Local Management by connecting a
Digital Equipment Corporation VT™ 320 series terminal or a PC
using VT320 emulation software to the TRXI’s COM 1 port.
LCD and Reset Button
The LCD provides status information about the TRXI such as power
up diagnostics, revision levels, serial numbers, and error alerts. The
TRXI also has a Reset Button to initialize the processor. Both the LCD
and the Reset Button are located on the front panel of the TRXI.
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.
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.
COM Port Applications
The front panel COM 1 port supports Local Management applications.
Future capabilities for TRXI’s serial ports include an SNMP proxy for
Uninterruptible Power Supplies (UPS), the Serial Line Internet
Protocol (SLIP), and Modem.
