INTRODUCTION
1.2.2 Management Access
Local Management (LM) is a firmware image embedded in both the
TRMM and TRMMIM that provides a management application interface
for monitoring and managing the modules. Access to Local Management
is provided by the RS232 COM 2, or Console, communication port located
on the front panel of each module and via in-band Telnet connection.
COM 2 port
The COM 2 port supports out-of-band LM access via a management
terminal and modem connections (see Section 3.4 for terminal and modem
connection procedures).
NOTE: Remote Management access to the SNMP compliant TRMM and
TRMMIM is provided by the remote network management tools, Cabletron
Systems' Remote LANVIEW/Windows and SPECTRUM.
1.2.3 Testing and Troubleshooting Systems
LANVIEW LEDs, located on each module's front panel, provide an
at-a-glance means of monitoring the operational status of a module. LEDs
indicate whether a module is operating correctly, the ring speed, and
whether a module is actively managing other modules in the MMAC.
POWER UP DIAGNOSTIC test results appears on your management
terminal screen whenever the modules are powered on or reset. The tests
provide additional system-level information about the operational status of
a module. Your terminal must be connected to the COM 2 port to view the
tests. See Chapter 4, Testing and Troubleshooting, for more information
about monitoring systems.
1.2.4 System Safeguards
The TRMM and TRMMIM both support UPS device monitoring (from
LANVIEW or SPECTRUM) via connection to the COM 1 port. The UPS
device provides a regulated and constant power source in the event of
power-supply faults. Contact your Cabletron Sales Representative to order
the necessary port connectors.
