1. About this Manual
Thank you for purchasing a Moxa managed Ethernet switch. Read this user’s manual to learn how to
connect your Moxa switch to Ethernet-enabled devices used for industrial applications.
A synopsis of chapters 2 and 3 are given below:
Chapter 2: Getting Started
In this chapter, we explain the initial installation process for a Moxa switch. Moxa switches provide three
interfaces to access the configuration settings: USB console interface, command line interface, and web
console interface.
Chapter 3: Featured Functions
In this chapter, we explain how to access a Moxa switch’s various configuration, monitoring, and
management functions. The functions can be accessed by USB console, Telnet console, and web console
(web browser). We describe how to configure the switch functions via web console, which provides the
most user-friendly way to configure a Moxa switch.

2. Getting Started
In this chapter, we explain how to install a Moxa switch for the first time. There are three ways to access
the Moxa switch’s configuration settings: USB console, command line interface, or web-based interface. If
you do not know the Moxa switch’s IP address, you can open the USB console by connecting the Moxa
switch to a PC’s USB port with a USB cable. You can open the Telnet or web-based console over an Ethernet
LAN or over the Internet.
The following topics are covered in this chapter:

Opening the Moxa switch’s Telnet or web console over a network requires that the PC host and Moxa switch
are on the same logical subnet. You may need to adjust your PC host’s IP address and subnet mask. By
default, the Moxa switch’s IP address is 192.168.127.253 and the Moxa switch’s subnet mask is
255.255.255.0 (referred to as a Class B network). Your PC’s IP address must be set to 192.168.xxx.xxx if
the subnet mask is 255.255.0.0, or to 192.168.127.xxx if the subnet mask is 255.255.255.0.

3. Featured Functions
In this chapter, we explain how to access the Moxa switch’s various configuration, monitoring, and
management functions. These functions can be accessed by USB console, Telnet console, or web console.
The USB console can be used if you do not know the Moxa switch’s IP address. To access the USB console,
connect switch’s USB port to your PC’s COM port. The Telnet and web consoles can be opened over an
Ethernet LAN or the Internet.
The web console is the most user-friendly interface for configuring a Moxa switch. In this chapter, we use
the web console interface to introduce the console functions. There are only a few differences between the
web console, USB console, and Telnet console.

Password Login Policy
In order to prevent hackers from cracking the password, Moxa switches allow users to configure a password
for their account and lock the account in the event that the wrong password is entered. The account
password policy requires passwords to be of a minimum length and complexity with a strength check. If
Account Login Failure Lockout is enabled, you will need to configure the Retry Failure Threshold and
Lockout Time parameters. If the number of login attempts exceeds the Retry Failure Threshold, users will
need to wait the number of minutes configured in Lockout Time before trying again.
Network
Network configuration allows users to configure both IPv4 and IPv6 parameters for management access
over the network. The Moxa switch supports both IPv4 and IPv6, and can be managed through either of
these address types.

The IPv6 settings include two distinct address types—Link-Local Unicast addresses and Global Unicast
addresses. A Link-Local address makes the switch accessible over IPv6 for all devices attached to the same
local subnet. To connect to a larger network with multiple segments, the switch must be configured with a
Global Unicast address.

IEEE 1588
The following information is taken from the NIST website at http://ieee1588.nist.gov/intro.htm:
“Time measurement can be accomplished using the IEEE Standard for a Precision Clock Synchronization
Protocol for Networked Measurement and Control Systems (IEEE 1588-2008) to synchronize real-time
clocks incorporated within each component of the electrical power system for power automation
applications.
IEEE 1588, which was published in November 2002, expands the performance capabilities of Ethernet
networks to control systems that operate over a communication network. In recent years an increasing
number of electrical power systems have been using a more distributed architecture with network
technologies that have less stringent timing specifications. IEEE 1588 generates a master-slave relationship
between the clocks, and enforces the specific timing requirements in such power systems. All devices
ultimately get their time from a clock known as the grandmaster clock. In its basic form, the protocol is
intended to be administration free.”
How Does an Ethernet Switch Affect 1588 Synchronization?
The following content is taken from the NIST website at http://ieee1588.nist.gov/switch.htm:
“An Ethernet switch potentially introduces multi-microsecond fluctuations in the latency between the 1588
grandmaster clock and a 1588 slave clock. Uncorrected these fluctuations will cause synchronization errors.
The magnitude of these fluctuations depends on the design of the Ethernet switch and the details of the
communication traffic. Experiments with prototype implementations of IEEE 1588 indicate that with suitable
care the effect of these fluctuations can be successfully managed. For example, use of appropriate statistics
in the 1588 devices to recognize significant fluctuations and use suitable averaging techniques in the
algorithms controlling the correction of the local 1588 clock will be good design means to achieve the
highest time accuracy.”

Can Ethernet switches be designed to avoid the effects of these
fluctuations?
A switch can be designed to support IEEE 1588 while avoiding the effects of queuing. In this case two
modifications to the usual design of an Ethernet switch are necessary:
1. The Boundary Clock and Transparent Clock functionalities defined by IEEE 1588 must be
implemented in the switch.
2. The switch must be configured so that it does not pass IEEE 1588 message traffic using the normal
communication mechanisms of the switch.
Such an Ethernet switch will synchronize clocks directly connected to one of its ports to the highest possible
accuracy.

Warning Notification
Since industrial Ethernet devices are often located at the endpoints of a system, these devices will not
always know what is happening elsewhere on the network. This means that an industrial Ethernet switch
that connects to these devices must provide system maintainers with real-time alarm messages. Even when
control engineers are out of the control room for an extended period of time, they can still be informed of
the status of devices almost instantaneously when exceptions occur. The Moxa switch supports different
approaches to warn engineers automatically, such as email, trap, syslog and relay output. It also supports
two digital inputs to integrate sensors into your system to automate alarms by email and relay output.
System Event Settings
System Events are related to the overall function of the switch. Each event can be activated independently
with different warning approaches. The Administrator can decide the severity of each system event.
