Preface
This manual contains some advanced network management knowledge, instructions, examples,
guidelines, and general theories. The contents are designed to help users manage the switch and
use its software, a background in general theory is a must when reading it. Please refer to the
Glossary for technical terms and abbreviations.
Who Should Use This User Manual
This manual is to be used by qualified network personnel or support technicians who are familiar with
network operations, and might be useful for system programmers or network planners as well. This
manual also provides helpful and handy information for first time users. For any related problems,
please contact your local distributor. If they are unable to assist you, please redirect your inquiries to

1 Introduction
1.1 What is a Managed Industrial Switch
Atop’s EH (Ethernet Switching Hub), EHG (Ethernet Switching Hub Full Gigabit) are product lines of
powerful managed industrial switch which are referred to as OSI Layer 2* bridging devices. Unlike an
“unmanaged” switch, which is normally found in homes or in 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 by 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 switch is an industrial switch (as opposed to 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.
The managed switch is designed to provide faster, secure, and more stable network. One advantage
that makes it a powerful switch is that it supports technologies such as ERPS, iA-Ring, RSTP, MSTP,
and MRP. These technologies provide better network reliability and decrease recovery time down to
less than 20 ms.
The managed switch supports 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 a brand new network-
management experience.
*Note:
Throughout the manual, the symbol * indicates that more detailed information of the subject will be
provided at the end of this book.

2 Configuring with a Web Browser
Chapter 2 explains how to access the managed switch for 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 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
console and 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 using their web browsers (Internet Explorer 8 or 11,
Firefox 37, Chrome 42 or later versions recommended). We will proceed to use a web browser to
introduce the managed switch’s functions.
2.1.1 Default Settings
Below is a list of default factory settings. This information will be used during the login process. Make
sure the computer accessing the switch has an IP address in the same subnet and the subnet mask
is the same.
IP Address: 10.0.50.1
Subnet Mask: 255.255.0.0
Default Gateway: 10.0.0.254
User Name: NULL (leave it blank)
Password: NULL (leave it blank)
