INTRODUCTION

Overview

This User Manual provides detailed information and guidance on how to install and

connect the SG72660M switch in your network system and how to configure and

monitor the SG72660M through the web interface. Detailed explanations in of hardware

and software functions are shown as well as examples of the operation for using the

web-based interface.

The SG72660M switch from VERSITRON, Inc. is an affordable, feature-rich,

managed switch that provides a reliable infrastructure for your business network. The

switch delivers intelligent features you need to improve the availability of your critical

business applications, protect your sensitive information, and optimize your network

bandwidth to deliver information and applications more effectively. It provides the ideal

combination of affordability and capabilities for entry level or advanced networking

applications and helps you create a more efficient, better-connected workforce.

The SG72660M web managed switch provides 26 ports in a single device. The

specifications are highlighted as follows.

 L2+ features provide better manageability, security, QoS, and performance.

 High port count design with all Gigabit Ethernet ports

 Supports guest VLAN, voice VLAN, Port based, tag-based and Protocol-based

VLANs.

 Supports 802.3az Energy Efficient Ethernet standard

 Supports 8K MAC table

 Supports IPv6/ IPv4 Dual stack

 Supports s-Flow

 Supports Easy-Configuration-Port for implementation of IP Phones, IP

Cameras, or Wireless environment.

Chapter 1 Operation of Web-based Management

Initial

Configuration

This chapter instructs you how to configure and manage the

SG72660M switch through the web user interface. With this facility,

you can easily access and monitor, through any one port of the

switch, the status of any feature, including MIBs status, each port

activity, Spanning Tree status, port aggregation status, multicast

traffic, VLAN and priority status, illegal access record, and so on.

The default values of the SG72660M are listed in the table below:

IP Address

192.168.1.1

Subnet Mask

255.255.255.0

Default Gateway

192.168.1.254

Username

admin

Password

After the interface of the SG72660M has been configured, you can

browse it. For instance, type http://192.168.1.1 in the address

row in a browser. It will show the following screen and ask you to

input the username and password in order to login and access

authentication.

The default username is “admin” and password is empty. For the

first time to use, please enter the default username and password,

and then click the <Login> button. The login process now is

completed. In this login menu, you have to input the complete

username and password respectively. The SG72660M will not give

you a shortcut to username automatically. This may seem

inconvenient, but it is safer.

The SG72660M supports a simple user management function

allowing only one administrator at a time to configure the system. .

If there are two or more users using the administrator’s identity, it

will allow only the one who logins first to configure the system.

The rest of the users, even with administrator’s identity, can only

monitor the system. Those who have no administrator’s identity,

can only monitor the system. There are only a maximum of three

users able to simultaneously login in to the SG72660M switch.

NOTE:

When you login to the SG72660M switch to utilize web

management, you must first type the Username of the

administrator. The Password field is left blank. After typing

the Username, please press enter. The web management

page appears.

When you login to the SG72660M switch Web UI

management, you can use both ipv4 ipv6 login to manage.

To optimize the display effect we recommend you use

Microsoft IE 6.0 above, Netscape V7.1 above or FireFox

V1.00 above and have the resolution 1024x768. The switch

supports neutral web browser interface.

NOTE:

The SG72660M function enables dhcp, so If you do not have

a DHCP server to provide ip addresses to the switch, the

switch default ip address is 192.168.1.1

Figure 1 The login page

NOTE: If you need to configure a function or parameter, then

you can refer to the information in the User Manual. Or you

could access the switch and click the "help" under the web

GUI. The switch will pop-up the simple help content to

assist you with setting the parameters or functions.

NOTE: Any configuration changes made to the switch must be saved in the start

configuration in order to be applied to the next start-up sequence.

Go to: Maintenance  Save/Restore  Save Start shown in Section 5-3.2.

SG72660M web help function:

CONNECTING

NETWORK

DEVICES

The switch is designed to be connected to 10, 100 or

1000Mbps network cards in PCs and servers, as well as

to other switches and hubs. It may also be connected

to remote devices using optional SFP transceivers.

TWISTED-PAIR

DEVICES

Each device requires an unshielded twisted-pair (UTP)

cable with RJ-45 connectors at both ends. Use

Category 5, 5e or 6 cable for 1000BASE-T connections,

Category 5 or better for 100BASE-TX connections.

CABLING

GUIDELINES

The RJ-45 ports on the switch support automatic

MDI/MDI-X pinout configuration. Consequently, you

can use standard straight-through twisted-pair cables

to connect to any other network device (PCs, servers,

switches, routers, or hubs).

See Appendix B for further information on cabling.

C

AUTION

:

Do not plug a phone jack connector into an RJ-45

port. This will damage the switch. Use only twisted-pair

cables with RJ-45 connectors that conform to FCC

standards.

CONNECTING TO PCS, SERVERS, HUBS AND SWITCHES

Step 1. Attach one end of a twisted-pair cable segment to the device’s RJ-45

connector.

Step 2. If the device is a network card and the switch is in the wiring closet, attach the

other end of the cable segment to a modular wall outlet that is connected to

the wiring closet. (See the section “Network Wiring Connections.”) Otherwise,

attach the other end to an available port on the switch.

Note: Make sure each twisted pair cable does not exceed 100 meters (328 ft) in length.

NOTE: Avoid using flow control on a port connected to a hub

unless it is actually required to solve a problem. Otherwise,

back pressure jamming signals may degrade overall

performance for the segment attached to the hub.

Step 3. As each connection is made, the Link LED (on the switch) corresponding to

each port will light green (1000 Mbps) or amber (100 Mbps) to indicate that

the connection is valid.

NETWORK WIRING CONNECTIONS

Today, the punch-down block is an integral part of many of the newer equipment racks.

It is actually part of the patch panel. Instructions for making connections in the wiring

closet with this type of equipment are as follows.

Step 1. Attach one end of a patch cable to an available port on the switch, and the

other end to the patch panel.

Step 2. If not already in place, attach one end of a cable segment to the back of the

patch panel where the punch-down block is located, and the other end to a

modular wall outlet.

Step 3. Label the cables to simplify future troubleshooting. See “Cable Labeling and

Connection Records” on page 29

Chapter 2 System Configuration

This chapter describes all the basic configuration tasks which includes the System

Information and any management features of the SG72660M switch (e.g. Time, Account,

IP, Syslog and SNMP.)

2-1 System Information

After you login, the switch shows you the “system information”. This is the default page and it

tells you the basic information of the system, including “Model Name”, “System Description”,

“Contact”, “Device Name”, “System Up Time”, “BIOS Version”, “Firmware Version”,

“Hardware-Mechanical Version”, “Serial Number”, “Host IP Address”, “Host Mac Address”,

“Device Port”, “RAM Size” , and “Flash Size”. With this information, you will know the

software version used, MAC address, serial number, how many ports are good and so on.

2-1.1 Information

The switch system information is provided here.

Web interface

To configure System Information in the web interface:

1. Click SYSTEM, System, and Information.

2. Specify the contact information for the system administrator as well as the name and

location of the switch. Also indicate the local time zone by configuring the appropriate

offset.
