1.5 OPERATIONAL MODES AND LM ACCESS
The number of LM applications you can access is contingent upon which
operational mode you have specified for the TRBMIM/TRBMIM-T. The
TRBMIM/TRBMIM-T can be configured to operate as a dedicated
Source-Route bridge or as a combination bridge and Token Ring
management module. See the
TRBMIM-T User’s Guide included with
the TRBMIM-T and the
TRMM, TRBMIM, & TRMMIM Installation
Guide
included with the TRBMIM for information about operational
mode specifications and selecting an operational mode.
The title of a LM screen indicates the current operating mode of the
TRBMIM/TRBMIM-T.
When the TRBMIM/TRBMIM-T is in the Bridge-Only mode, the LM
screen displays this title:
“TRBMIM BRIDGE LOCAL MANAGEMENT”
When the TRBMIM/TRBMIM-T is in the Bridge/Management mode, the
LM screen displays this title:
“TRBMIM CHASSIS LOCAL MANAGEMENT”
Table 1-1 lists LM applications you can access when the
TRBMIM/TRBMIM-T is configured to operate in either operational
mode.

INTRODUCTION

The next chapter describes how to connect a management terminal or PC
to the TRBMIM/TRBMIM-T LM-access Console port and how to access
the LM Password screen.

CHAPTER 2
ACCESSING LOCAL MANAGEMENT
This chapter describes how to access LM via a direct or remote
management terminal connection. It describes management terminal
requirements and how to connect a VT-series terminal, a PC, and a
modem to the TRBMIM/TRBMIM-T. It also describes terminal and
modem setup parameters for the connection and requirements for
establishing an in-band connection to LM via Telnet.
2.1 MANAGEMENTTERMINAL REQUIREMENTS
The following terminals can be used to access LM:
• Digital Equipment Corporation VT-series terminal or VT-type
terminal running VT-series software
• IBM or compatible PC running a VT-series emulation program
2.2 CONNECTING AVT-SERIESTERMINAL
Use the RS-232 console cable and the RJ45-to-DB25 VT-series adaptor
shipped with the TRBMIM/TRBMIM-T to connect the VT-series
terminal, as shown in Figure 2-1.
To connect the VT-series terminal:
1. Insert the cable’s DB9 connector into the LM Console port.
2. Attach the VT-series RJ45-to-DB25 adaptor to the RJ45 connector at
the other end of the cable.
3. Connect the adaptor into the appropriate serial communications port
on the VT-series terminal, as specified in the user instructions
included with the terminal.
See Section 2.5 for terminal setup parameters.

with the TRBMIM/TRBMIM-T to connect the PC, as shown in
Figure 2-2.
To connect the PC:
1. Insert the cable’s DB9 connector into the LM Console port.
2. Attach the PC RJ45-to-DB9 adaptor to the RJ45 connector at the other
end of the cable.
