■Reset Button - used to reboot the Management Module and the
switch in which it is installed. This clears any temporary error condi-
tions that may have occurred, executes the module and switch self
tests, and returns all network activity counters to zero. The counters
are displayed in the switch console interface and through network
management applications.

Description
• When pressed with the Reset button in a specific pattern, clears
any configuration changes you may have made through the
switchconsoleandSNMPmanagement,andrestores thefactory
default configuration to the switch and the module. See “Restor-
ing the Factory Default Configuration” in chapter 7, “Trouble-
shooting” for the specific method to restore the factory default
configuration.
■Self Test LED - When lit, indicates that the Management Module or
the switch in which the module is installed is undergoing its self test,
which occurs every time the switch is plugged into a power source,
orasaresultofpressingtheResetbuttonontheManagementModule,
or from rebooting or resetting the switch from the switch console or
from network management.
■Fault LED - When lit with the Self Test LED, indicates that the
Management Module is executing its self test.The self test normally
takes approximately 10 seconds. If the SelfTest and FaultLEDs stay
on for longer than this, or if the Fault LED is flashing at any time, an
error has occurred on the module. See chapter 7, “Troubleshooting”
for more information on the LED and error recovery procedures.
■Console RS-232 Port - This port is used to connecta console to the
switch, either directly using the serial cable supplied with the
ManagementModule,orthroughamodemconnection.Theseconnec-
tions are described in chapter 3, “The Switch Console”. The console
can be either a PC running a VT-100 terminal emulator, or a VT-100
terminal itself.
■MAC Address - This is the unique hardware identity of the manage-
ment module. It is also used to identify the switch into which the
module is installed, and can be used in network connectivity tests
between the switch and other network devices. In an IPX network,

Description
Module Features
WhenyouinstalltheSwitch208/224ManagementModuleinyourSwitch208T
or 224T, you get these enhanced switch capabilities:
■Full-duplex port operation. By default, the 10 Mbit/s and
100 Mbit/s ports on the Switch 208/224 operate in half-duplex mode.
With the Switch Management Module installed, these ports can be
configured to operate in full-duplex mode.
■Address Aging. The Switch 208/224 automatically learns the MAC
addressofthedevicesconnectedtoitsportsandstoresthoseaddress-
es in an 8000-entry address table. When a device is moved, its new
location is automatically learned and kept in the table so proper
communication is maintained with the device. Withthe Management
Module installed,theadditionalbenefitis thatinactiveaddresses are
aged out of the table -- the table is kept up to date with the addresses
of active nodes only.
■Spanning Tree Support. The Switch 208/224 uses the IEEE 802.1d
Spanning Tree Protocol (STP) to ensure that only one path at a time
isactivebetweenanytwonodesinthenetwork,thuspreventingloops
that cause broadcast storms from occurring in the network topology.
By default, STP is disabled on the switch. You can use theswitch console
toenableSTPoperation;seechapter4,“ConfiguringtheSwitchFromthe
Console” for those configuration procedures. For more information on
how STP works, see appendix D, “Spanning Tree Operation”.
■Switch Console. The Management Module has an RS-232 port to
which you can connect a console that can be used to configure,
monitor, and troubleshoot the switch and its ports. The console
interface can be used “out-of-band” from a PC or terminal directly
connected to the port or remotely through a modem connection, or
“in-band” through a Telnet session. For more information on the
switchconsole,seethesection“SwitchConsoleFeatures”inchapter
3, “The Switch Console”.
■Network Management. The Management Module has firmware
agents onboardthat provideSNMP Network Managementcontrol of
the switch, support for RMON (four groups) and HP Embedded
Advanced Sampling Environment (EASE) agents to diagnose net-
work problems to help optimize network performance. For more
information the network management features provided by the Man-
agement Module and how to configure those features, see chapter 6,
“Using SNMP to Monitor and Manage the Switch”.

The Switch Console
Overview
About the Console Interface. Theconsoleinterfaceenablesyoutorecon-
figuretheswitchandtomonitortheswitchstatusandperformance.Itconsists
of a series of management screens accessed through a menu-driven screen
structure that begins at the Main Menu.
The switch console interface enables you to use a PC or a terminal to do the
following:
■Modify the switch’s configuration, or provide configuration for Telnet or
networkmanagementaccessfromanSNMP-basedmanagementprogram
such as Hewlett-Packard’s AdvanceStack Assistant (ASA)
■Monitor the switch and port status and network activity counters
■Control console security by configuring passwords
■Use the switch’s event log and some advanced commands to help in
troubleshooting
■Download new software
Note The Switch 208/224 and its Management Module are shipped with a factory
default configuration that enables operation as a multiport learning bridge
when installed in a network. All ports are enabled, Spanning Tree Protocol
support isdisabled,and SNMP network managementis enabled overIPXand
IP (by way of Bootp). For this operation, connecting a console device is
unnecessary. However, for some ofthe other uses listed above, you will need
to use the switch console.
This chapter describes the following features:
■Connecting a console to the switch (page 3-2)

The Switch208/224Management Module offers two methods ofaccess tothe
console interface:
■Out-of-band console access:
• Directly connected to the Console RS-232 port, using a serial cable
and a PC running a VT-100 terminal emulator or an actual VT-100
terminal
• Remotely connected to the Console RS-232 port, using modems and
a PC running a terminal emulator or an actual terminal
■In-Band access using Telnet from a PC or UNIX station on the network,
and a VT-100 terminal emulator. This method requires that you first
configure an IP address and subnet mask by using either out-of-band
console access or Bootp. The Management Module allows one outbound
and one inbound Telnet session to be running simultaneously. Itcan also
simultaneously support one console session through the Console RS-232
port and one Telnet console session.
You can put security restrictions on console access by setting Manager-level
and Operator-level passwords. See “Using Password Security” later in this
chapter.
Default Serial Communication Settings
The default communication settings on the Switch Management Module are:
• 9600 baud
• 8 data bits
• 1 stop bit
• XON/XOFF
• For Windows Terminal program, also disable (uncheck) the “Use
Function, Arrow, and Ctrl Keys for Windows” option.
Configure your PC or terminal to operate with these settings. If you want to
operate the terminal using a different configuration, make sure you change
with settings on both the terminal and on the switch. Change the switch
settings first, then change the terminal settings, and reestablish the console
session.
