6. (Optional) Connect a Console to the Hub (Hub 12M
and Hub 24M only)
The Hub 12M and Hub 24M have a full-featured, easy to use console interface
for performing the following tasks:
Monitor hub and port status and observe network activity counters
Modify the hub's configuration
Access diagnostic tools to help in troubleshooting
Download new software to the hub
Add passwords to control console, web browser interface, and
network management access to the hub
The console can be accessed through these methods:
Out-of-band: The Hub 12M and Hub 24M come with a serial cable for
connecting a PC, or ASCII or VT-100 terminal to be used as a console
directly to the hub. If the PC or terminal has a 25-pin serial connector, you
can use a readily available 9-pin to 25-pin serial cable, or attach a 9-to-25
pin adapter to the end of the supplied cable.
In-Band: Access the console using Telnet from a PC or UNIX station on
the network, and an ASCII or VT-100 terminal emulator. This method
requires that you first configure the hub with an IP address and subnet
mask by using either out-of-band console access or through DHCP/Bootp.
The hub 12M and Hub 24M can, at any given time, support one console session
through the Console Port or one Telnet console session. There is no restriction
on the number of web browser interface sessions with the hub.
Terminal Configuration
To connect a console to the hub, configure the PC terminal emulator as an
ASCII (TTY) or VT-100 (ANSI) terminal or use an ASCII or VT-100 terminal and
configure it to operate with these settings:
any baud rate from 2400 to 115200 (the hub senses the speed)
8 data bits, 1 stop bit, no parity, XON/XOFF flow control
For Windows Terminal program, also disable (uncheck) the "Use Func-
tion, Arrow, and Ctrl Keys for Windows" option.
For the Hilgrave HyperTerminal program, select the "Windows keys"
option for the "Function, arrow, and ctrl keys act as" parameter.
If you want to operate the console using a different configuration, make sure
you change the settings on both the terminal and on the hub. Change the hub
settings first, then change the terminal settings, and reestablish the console
session.
