AT-FH812u and AT-FH824u Software
Introduction
The AT-FH812u and AT-FH824u hub (and the connected stack) is managed
through a direct console or modem connection to the AT-FH801u network
management agent module's serial port, using Telnet to access the hub over the
network, a standard browser to access the Agent Module's embedded web agent,
or with SNMP-based network management software. Once you connect a terminal
or PC to the serial port on the hub, you can perform the following tasks:
❑ Enable/disable any port
❑ Set the communication mode for any port
❑ Configure SNMP parameters
❑ Select RMON options
❑ Configure port security
❑ Display system information or statistics
❑ Download system firmware
❑ Restart the system

The hub includes a menu-dr iven con fig uratio n progr am. T he ASCI I inte rface to t his
program is accessed by making a direc t co nne ction to the serial port on the Agent
Module, or by a Telnet connection to the hub over the network.
This section describes how to access the menu-driven configuration program via:
❑ Onsite connection
— A terminal or workstation connected to the serial port locally on th e
Agent Module.
❑ Modem connection
— A workstation connected to the serial port of a remote via modems.
❑ Telnet connection
— A workstation connected to a remote hub via a Telnet connection
through the network.
It also describes how to access the embedded web agent over the network using
any standard browser, or with network management software or other third-party
mangement software.
Attach a VT100-compatible terminal, or a PC running a terminal emulation
program, to the serial port on the Agent Module. Use the null-modem cable
provided with this package, or a null modem connection that complies with the
wiring assignments shown in the back of this guide.
Connecting a
Modem
When attaching to a PC, mak e the following term inal settings:
❑ Terminal emulation type to VT100
❑ Specify the port used by your PC, for example COM 1~4
❑ Communications to 8 data bits, 1 stop bit, no parity, and 9600 bps (for
initial configuration)
❑ Flow control to none

modem's serial port using standard cabling. For most modems, which use a 25-pin
port, you will need to provide an RS232 cable with a 9-pin connector on one end
and a 25-pin connection on the other end. You do not have to set the modem at
the hub's site, because the hub will automatically configure it to auto-answer
mode.

specify the port used by your PC (COM 1~4), and then set communications to 8

Making a Telnet
Connection
Connecting for an
In-Band Network
Before you access the hub via an in-band Telnet connection or with a Web
browser, you must first configure it with a valid IP address, subnet mask and
default gateway, using an out-of-band connection or BootP protocol. Once the
hub's IP parameters are configured, you can acc ess th e on-board configuration
program from anywhere within the attached network.
Note
Use the Network Configuration menu to specify the maximum number of
simultaneous Telnet connections supported by the system.
The on-board configuration program can be accessed by running Telnet or a web
browser (Internet Explorer
from any computer attached to the network. It can also be managed from a
computer using network manag em ent software. However, prior to acce ssing the
hub (or connected stack), you must first configure it with a valid IP address, subnet
mask, and default gateway using an out-of-band connection or BootP protocol.
The on-board program on ly provides access to basi c configuration func tions. To
access the full range of SNMP mangement functions, you must use SNMP-based
network mangement software.
