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 MANAGEMENT T ERMINAL 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 A VT-SERIES TERMINAL
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.

ACCESSING LOCAL MANAGEMENT
2.7.1 Accessing LM Via Telnet
Once the TRBMIM/TRBMIM-T is assigned an IP address, you can
access Local Management via Telnet connection from any TCP/IP based
node on the network. You establish the Telnet connection to LM by
specifying the TRBMIM/TRBMIM-T IP address in the Telnet
application. See the user instructions included with your Telnet
application for more information. See Section 4.1.2 for information on
setting an IP address for the TRBMIM/TRBMIM-T.
2.7.2 Accessing LM Via Remote Modem Connection
To access LM via modem connection:
1. Turn on the modem. The modem must be set for Auto Answer and
Data Carrier Detect must be active. Refer to your modem’s user
manual for operating instructions.
2. Call the modem attached to the TRBMIM/TRBMIM-T.
The LM Password screen appears (see Figure 2-4) after you have
established the connection.
2.7.3 Disconnecting A Current LM User
If another user is currently logged on to LM when you try to access LM,
via direct or remote connection (including Telnet), the screen shown in
Figure 2-5 appears asking if you want to disconnect the other user so you
can access LM.
2-8
ACCESSING LOCAL MANAGEMENT
A TRBMIM Local Management Session is currently in use.
(This prompt will time out in 60 seconds)
Would you like to disconnect that user?
Figure 2-5 LM Disconnection Query
To disconnect the current user, enter y for yes at the cursor, as shown in
Figure 2-6. If you do not want to disconnect the current user, enter
n for
