Chapter 3. 8237 Administration
This chapter explains how to manage your 8237 installation. Its primary emphasis
will be on using the built-in user interface. You can also use SNMP to manage your
8237 installation. See "Preparing for SNMP Management" on page 3-48 for details.
The 8237 User Interface Program
The 8237 incorporates a powerful user interface that can be used to manage
individual 8237s or a complete stack using a terminal emulation program that
supports VT100 emulation (out-of-band), or using Telnet over an IP connection
(in-band).
Note: Telnet is a component of most TCP/IP applications. You will need to install
TCP/IP before you can take advantage of this option.
For more information on using Telnet over an IP connection, see "Management
Using Telnet" on page 3-47.
Management Using Terminal Emulation Software
You can manage your 8237 installation in one of two ways using terminal emulation
software:
•
By means of a direct, null-modem cable connection
•
By means of the public telephone network, using modems
Obtain and install a terminal emulation software application that is compatible with
your workstation’s operating system and that supports VT100 emulation.
Communicating Using a Null-Modem Cable
The 8237’s management port can communicate at speeds of 9600, 19 200, or
38 400 bits per second; this port speed can be selected by in-band or out-of-band
commands. The default is 9600 bits per second, which is the only speed at which
the Model 001 can communicate. The Model 002 and Model 003 can communicate
at all three speeds. To communicate with the 8237 for the first time, configure the
terminal emulation application as follows:
•
Default speed of 9600 bps
•
No parity
•
8 data bits
•
1 stop bit
•
No flow control
•
VT100 emulation
•
The communications port of the workstation that you have configured in the
emulation software
Note: Some emulation applications (such as many Windows-based programs) use
the workstation keyboard's cursor movement keys: for example, to switch between
windows. Because the 8237's user interface program uses the cursor movement
keys, it is necessary when using such terminal emulators to turn off this feature. In
Windows 3.1, for example, perform the following steps:
1
From the Program Manager window, double-click the Accessories group
icon.
