Warning
This equipment has been tested and found to comply with the limits for Class B digital
device pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio fre-
quency energy and, if not installed and used in accordance with the instructions in this
guide, may cause interference to radio communications. Operation of this equipment in
a residential area is likely to cause interference, in which case the user will be required
to correct the interference at his own expense.
The user is cautioned that changes and modifications made to the equipment without
approval of the manufacturer could void the user’s authority to operate this equipment.
It is suggested that the user use only shielded and grounded cables to ensure compliance
with FCC Rules.
This digital apparatus does not exceed the Class B limits for radio noise emissions from
digital apparatus set out in the radio interference regulations of the Canadian depart-
ment of communications.

Chapter 1: Switch Management
Configuration Options
For advanced management capability, the onboard management agent provides a
menu-driven system configuration program. This program can be accessed by a
direct connection to the serial port on the rear panel (out-of-band), or by a Telnet
connection over the network (in-band).
The management agent is based on SNMP (Simple Network Management
Protocol). This SNMP agent permits the switch to be managed from any PC in the
network using in-band management software.
The management agent also includes an embedded HTTP Web agent. This Web
agent can be accessed using a standard Web browser from any computer attached
to the network.
The system configuration program and the SNMP agent support management
functions such as:
• Enable/disable any port
• Set the communication mode for any port
• Configure SNMP parameters
• Add ports to network VLANs
• Display system information or statistics
• Configure the switch to join a Spanning Tree
• Download system firmware
Required Connections
Console Port (Out-of-Band) Connections
Attach a VT100 compatible terminal or a PC running a terminal emulation program
to the serial port on the switch’s rear panel. Use the null-modem cable provided with
this package, or use a null-modem connection that complies with the wiring
assignments shown in Appendix B of this guide.
When attaching to a PC, set terminal emulation type to VT100, specify the port used
by your PC (i.e., COM 1~4), and then set communications to 8 data bits, 1 stop bit,
no parity, and 9600 bps (for initial configuration). Also be sure to set flow control to
“none.” (Refer to “Configuring the Serial Port” on page 2-13 for a complete
description of configuration options.)
Note: If the default settings for the management agent’s serial port have been
modified and you are having difficulty making a console connection, you can
display or modify the current settings using a Web browser as described under
“Configuring the Serial Port” on page 3-5.

Switch Management
1-2
In-Band Connections
Prior to accessing the switch’s onboard agent via a network connection, you must
first configure it with a valid IP address, subnet mask, and default gateway using an
out-of-band connection or the BOOTP protocol.
Note: By default BOOTP is disabled and the IP address is set to 192.168.10.1. See
“IP Configuration” on page 2-10.
After configuring the switch’s IP parameters, you can access the onboard
configuration program from anywhere within the attached network. The onboard
configuration program can be accessed using Telnet from any computer attached to
the network. The switch can also be managed by any computer using a Web
browser (Internet Explorer 4.0 or above, or Netscape Navigator 4.0 or above), or
from a network computer using network management software.
Notes: 1. This switch supports four concurrent Telnet sessions.
2. The onboard program only provides access to basic configuration functions.
To access the full range of SNMP management functions, you must use
SNMP-based network management software.

2-1
Chapter 2: Console Interface
Log-in Screen
Once a direct connection to the serial port or a Telnet connection is established, the
log-in screen for the onboard configuration program appears as shown below.
Note: A banner message may be configured to appear before the Login screen. The
banner message is a login security alert. (See “Configuring the Banner Message”
on page 2-21.)
If this is your first time to log into the configuration program, then the default user
names are “admin” and “guest,” with the password “switch.” The Administrator has
Read/Write access to all configuration parameters and statistics, while the Guest
has Read Only access to the management program.
You should define a new administrator password, record it and put it in a safe place.
Select Console Login Configuration from the Management Setup Menu and enter a
new password for the administrator. Note that passwords can consist of up to 11
alphanumeric characters and are not case sensitive.
Note: You are allowed three attempts to enter the correct password; on the third failed
attempt the current connection is terminated.

Parameter Default Description
Interface Type Ethernet Indicates IP over Ethernet.
IP Address 192.168.10.1 IP address of the switch you are managing when accessing it over
the network. The switch supports SNMP over UDP/IP transport
protocol. In this environment, all systems on the Internet, such as
network interconnection devices and any PC accessing the switch
must have an IP address.
Valid IP addresses consist of four decimal numbers, of 0 to 255,
separated by periods. Anything outside of this format will not be
accepted by the configuration program.
Subnet Mask 255.255.255.0 Subnet mask of the switch. This mask identifies the host address
bits used for routing to specific subnets.
Default
Gateway
The gateway that the switch’s agent uses to pass data to the
management station. Note that the gateway must be defined if the
management station is located in a different IP segment.
IP State USER-CONFIG Specifies whether IP functionality is enabled via manual
configuration, or set by Boot Protocol (BootP). Options include:
USER-CONFIG -IP functionality is enabled based on the default or
user specified IP configuration.
BOOTP-GET-IP - IP is enabled but will not function until a BootP
reply has been received. BootP requests will be broadcast 10
times, once every second, in an effort to learn its IP address. If no
response is received, the switch will use the default IP setting in
NVRAM. (BootP values can include the IP address, default
gateway, and subnet mask.)
