1 Introduction
1.1 Introduction to Industrial Managed Switch
Atop’s EH)Ethernet Switching Hub or Fast Ethernet Switching Hub(75XXseries are product lines of powerful
industrial managed switch whichare referred to asOpen Systems Interconnection )OSI( Layer 2bridgingdevices.
Unlike an “unmanaged” switch, which is normally found in homes or in Small Office/Home Office )SOHO(
environments and runs in “auto-negotiation” mode, each port on a “managed switch” can be configured for its link
bandwidth, priority, security, and duplex settings. The managed switches can be managed bySimple Network
Management Protocol )SNMP(software, web browsers, Telnet, or serial console. Since every single port can be
configured to specific settings, network administrators can better control the network and maximize network
functionality.
Atop’s managed switchisalso an industrial switch and not a commercial switch.A commercial switch simply works
in a comfortable office environment. However, an industrial switch is designed to perform in harsh industrial
environments, i.e., extreme temperature, high humidity, dusty air, potential high impact, or the presence of
potentially high static charges. Atop’s managed switch works fine even in these environments.
Atop’smanaged switchis designed to provide faster, secure, and more stable network. One advantage that makes
it a powerful switch is that it supports network redundancy protocols/technologiessuch asEthernet Ring Protection
Switching )ERPS, iA-Ring, Rapid Spanning Tree Protocol )RSTP(, Multiple Spanning Tree Protocol )MSTP(, and
Media Redundancy Protocol )MRP(. These protocols provide better network reliability and decrease recovery time
down to less than 20 ms.
Atop’smanaged switchsupports a wide range of IEEE standard protocols. This switch is excellent for keeping
systems running smoothly, reliable for preventing system damage or losses, and friendly to all levels of users. The
goal of this innovative product is to bring users an enhanced networkmanagement experience.
Note:
Throughout the manual, the symbol * indicates that more detailed information of the subject will be provided at the
end of this book or as a footnote.

2 Configuring with a Web Browser
Chapter 2 explains how to access the industrial managed switchfor the first time. There are three ways to configure
this Ethernet Switch:
1. Web browser
2. Telnet console
3. Serial console
The web browser and the telnet console methods allow users to access the switch over the Internet or the Ethernet
LAN, while the serial console method requires a serial cable connection between the consoleand the switch. There
are only a few differences among these three methods.Users are recommended to use the web browser method
to configure the system because of its user-friendly interface.
2.1 Web-based Management Basics
Users can access the managed switch easily usingtheir web browsers )Internet Explorer 8 or 11, Firefox44, Chrome
48 or later versions are recommended(. We will proceed to use a web browser to introduce the managed switch’s
functions.
2.1.1 Default Factory Settings
Belowis a list of default factory settings. This information will be used during the login process. Make sure that the
computer accessing the switch has an IP address in the same subnet and the subnet mask is the same. Please
pay attention that username and password are case sensitive.
IP Address: 10.0.50.1
Subnet Mask: 255.255.0.0
Default Gateway: 0.0.0.0
User Name: admin
Password: default

2.1.2 Login Process and Main Window Interface
Before users can access the configuration, they have to log in. This can simply be done in the following steps.
1. Launch a web browser.
2. Type in the switch IP address )e.g. http://10.0.50.1(, as shown in Figure 2.1(.
NoteWhen the user name and password is left empty, the login prompt will not show.
Figure 2.1 IP Address for Web-based Setting
3. If it is the first time that the users access the managed switch, the web the browser such as Google
Chrome may detect that the switch does not have a valid certificate authority. The users can proceed
by clicking on the Advanced button as shown in Figure 2.2.
Figure 2.2 Example of Google's Chrome web brower invalid certificate authority
4. Once the Advanced button is clicked, an explanation text will appear below the button as shown in
Figure 2.3. Here at the bottom of the web page, there is a hyperlink that the users can click to access
the web GUI of the managed switch.

6. For security purpose, if the user did not enter the username and the password within 30 seconds, the
login page will time-out and an error notification page will show up. Even though the user entered the
correct username and password, the login procedure will not succeed if the login was done more than
30 seconds after the login page was first accessed. The notification page is shown in Figure 2.5. The
user can click on the Try again button to access the login page again.

7. If the user entered wrong passwords more than three times within 3 minutes, the account will be
temporary blocked for 15 minutes. An error pop-up notification will be shown as in Figure 2.6. The user
can click Try again button to access the login page again after the duration of 15 minutes.

Note:
1. Any unauthorized login to the managed switch will be recorded to device’s syslog. A pop-up notification is
shown in Figure 2.7.
2. After the user logins to the main interface if the user is idle or inactive for more than 5 minutes, the user will
be logged out automatically.
Figure 2.7 Notification on recording of unauthorized login
After the login process, the main interface will show up, as shown in Figure 2.8. The main menu (left side of the
screen) provides the links at the top-level links of the menu hierarchy and by clicking each item allows lower level
links to be displayed. Note that in this case the Port 1 is highlighted in green, indicating that the port is being
connected. Detailed explanations of each subsection will be addressed later as necessary.

2.2 Basic Information
To help users become familiar with the device, the Basic section provides important details of the switch. This is
also the main welcome screen once the user has logged in. The details make it easier to identify different switches
connected to the network. The Basic section is categorized into six subsections as shown in the left panel of Figure
2.9.
Figure 2.9 Basic Information Dropdown Menu
2.2.1 System Info
This subsection provides basic system information of Atop’s industrial managed switch. The user can check the
system name, model name, device description, MAC address, firmware version, and memory usage of the switch.
Note that Atop’s firmware generally consists of Application version and Kernel version. Figure 2.10 depicts an
example of Basic System Information of EHG7506-4PoE-2SFP. Table 2.1 summarizes the description of each
basic information.
