Installation
This chapter gives step-by-step instructions about how to install the
switch:
Selecting a Site for the Switch
As with any electric device, you should place the switch where it
will not be subjected to extreme temperatures, humidity, or
electromagnetic interference. Specifically, the site you select
should meet the following requirements:
- The ambient temperature should be between 32 and 104
degrees Fahrenheit (0 to 40 degrees Celsius).
- The relative humidity should be less than 90 percent,
non-condensing.
- Surrounding electrical devices should not exceed the
electromagnetic field (RFC) standards for IEC 801-3, Level 2
(3V/M) field strength.
- Make sure that the switch receives adequate ventilation. Do
not block the ventilation holes on each side of the switch or the
fan exhaust port on the rear of the switch.
- The power outlet should be within 1.8 meters of the switch.

Connecting to Power
Step 1: Connect the supplied AC power cord to the receptacle on the back
of the switch, and then plug it into a standard AC outlet with a
voltage range from 100 to 240 Vac.
zStep 2: Disconnect the power cord if you want to shut down the
switch.

Cabling
Step 1: First, ensure the power of the switch and end devices is turned off.
<Note> Always ensure that the power is off before any installation.
Step 2: Prepare cable with corresponding connectors for each type of port
in use.
<Note> To connect two regular RJ-45 ports between switches or hubs, you
need a cross-over cable.
Step 3: Consult Cable Specifications Table on previous page for cabling
requirements based on connectors and speed.
Step 4: Connect one end of the cable to the switch and the other end to a
desired device.
Step 5: Once the connections between two end devices are made
successfully, turn on the power and the switch is operational.

Switch Management
This chapter explains the methods that you can use to configure
management access to the switch. It describes the types of
management applications and the communication and management
protocols that deliver data between your management device
(workstation or personal computer) and the system. It also contains
information about port connection options.
This chapter covers the following topics:
• Management Access Overview
• Key Concepts
• Key Guidelines for Implementation
• Administration Console Access
• Web Management Access
• SNMP Access
• Standards, Protocols, and Related Reading
Management Access Overview
The switch gives you the flexibility to access and manage the
switch using any or all of the following methods.
The administration console and web browser interface support are
embedded in the switch software and are available for immediate
use.

Manageable Gigabit Switch
User’s Manual 17
Administration Console
The administration console is an internal, character-oriented, menu-
driven user interface for performing system administration such as
displaying statistics or changing option settings.
Using this method, you can view the administration console from a
terminal, personal computer, Apple Macintosh, or workstation
connected to the switch’s console port.
There are two ways to use this management method: direct access
or modem access. The following sections describe these methods.
Direct Access
Direct access to the administration console is achieved by directly
connecting a terminal or a PC equipped with a terminal-emulation
program (such as HyperTerminal) to the switch console port.
When using the management method, configure the terminal-emulation
program to use the following parameters (you can change these settings
after login):
[DEFAULT PARAMETERS]
♦115,200bps
♦8 data bits
♦No parity
♦1 stop bit
This management method is often preferred because you can remain
connected and monitor the system during system reboots. Also, certain
error messages are sent to the serial port, regardless of the interface
through which the associated action was initiated. A Macintosh or PC
attachment can use any terminal-emulation program for connecting to
the terminal serial port. A workstation attachment under UNIX can use
an emulator such as TIP.

Manageable Gigabit Switch
18 User’s Manual
Modem Access
You can access the switch’s administration console from a PC or
Macintosh using an external modem attached to the console port. The
switch management program provides Console Port screen, accessible
from the Basic Management screen, that lets you configure parameters
for modem access.
When you have configured the external modem from the administration
console, the switch transmits characters that you have entered as
output on the modem port. The switch echoes characters that it receives
as input on the modem port to the current administration console
session. The console appears to be directly connected to the external
modem.
Web Management
The switch provides a browser interface that lets you configure and
manage the switch remotely.
After you set up your IP address for the switch, you can access the
switch’s web interface applications directly in your web browser by
entering the IP address of the switch. You can then use your web
browser to list and manage switch configuration parameters from
one central location, just as if you were directly connected to the
switch’s console port.
Web Management requires either Microsoft Internet Explorer 4.01
or later or Netscape Navigator 4.03 or later.
SNMP-Based Network Management
You can use an external SNMP-based application to configure and
manage the switch. This management method requires the SNMP
agent on the switch and the SNMP Network Management Station
to use the same community string. This management method, in
fact, uses two community strings: the get community string and the
set community string. If the SNMP Network management station

Manageable Gigabit Switch
User’s Manual 19
only knows the set community string, it can read and write to the
MIBs. However, if it only knows the get community string, it can
only read MIBs. The default get and set community strings for
the switch are public.
Protocols
The switch supports the following protocols:
VIRTUAL TERMINAL PROTOCOLS, SUCH AS TELNET
A virtual terminal protocol is a software program, such as Telnet, that allows
you to establish a management session from a Macintosh, a PC, or a UNIX
workstation. Because Telnet runs over TCP/IP, you must have at least one
IP address configured on the switch before you can establish access to it
with a virtual terminal protocol.
<Note> Terminal emulation is different from a virtual terminal protocol in that
you must connect a terminal directly to the console port.
SIMPLE NETWORK MANAGEMENT PROTOCOL (SNMP)
SNMP is the standard management protocol for multivendor IP networks.
SNMP supports transaction-based queries that allow the protocol to format
messages and to transmit information between reporting devices and data-
collection programs. SNMP runs on top of the User Datagram Protocol
(UDP), offering a connectionless-mode service.
Management Architecture
All of the management application modules use the same
Messaging Application Programming Interface (MAPI). By
unifying management methods with a single MAPI, configuration
parameters set using one method (e.g. console port) are
immediately displayed the other management methods (e.g. SNMP
agent of web browser).
The management architecture of the switch adheres to the IEEE
open standard. This compliance assures customers that the switch is
compatible with, and will interoperate with other solutions that
adhere to the same open standard.

Menu-Driven Console Management
The switch provides a menu-driven console interface for
configuration purposes. The switch can be configured either locally
through its RS-232 port or remotely via a Telnet session. For the
later, you must specify an IP address for the switch first.
This chapter describes how to configure the switch using its menu-
driven console.
Logging on to the switch
At the screen prompt
Login:
Password:
LOGIN NAME
Enter the console interface factory default console name admin.
PASSWORD
Enter the factory default password (no password, press <Enter> directly).
Or enter a user-defined password if you followed the instructions later and
changed the factory default password.
Factory Default Password: no password, press <Enter> directly.
<Note> Only one console and three telnet users can log on to the switch
concurrently. However, it is not recommended that multiple users
modify the configuration at the same time.
* For initial IP settings, you must configure the switch through its
RS232 port.
