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.
Step 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.
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

Manageable Gigabit Switch
User’s Manual 15
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.
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 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.

<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.
