Chapter 2 Getting Started
This chapter explains how to access the EDS-728 for the first time. There are three ways to access
the switch: serial console, Telnet console, and web browser. The serial console connection method,
which requires using a short serial cable to connect the EDS-728 to a PC’s COM port, can be used
if you do not know the EDS-728’s IP address. The Telnet console and web browser connection
methods can be used to access the EDS-728 over an Ethernet LAN, or over the Internet.
The following topics are covered:
RS-232 Console Configuration (115200, None, 8, 1, VT100)
Configuration by Telnet Console
Configuration by Web Browser
Disabling Telnet and Browser Access
EDS-728 Series User’s Manual Getting Started

RS-232 Console Configuration (115200, None, 8, 1, VT100)
NOTE
Connection Caution!
1. You cannot connect to the EDS-728 simultaneously by serial console and Telnet.
2. You can connect to the EDS-728 simultaneously by web browser and serial console, or by
web browser and Telnet.
However, we strongly suggest that you do NOT use more than one connection method at the
same time. Following this advice will allow you to maintain better control over the
configuration of your EDS-728.
NOTE
We recommend using Moxa PComm Terminal Emulator, which can be downloaded free of
charge from Moxa’s website.
Before running PComm Terminal Emulator, use an RJ45 to DB9-F (or RJ45 to DB25-F) cable to
connect the EDS-728’s RS-232 Console port to your PC’s COM port (generally COM1 or COM2,
depending on how your system is set up).
After installing PComm Terminal Emulator, take the following steps to access the RS-232 Console
utility.
1. From the Windows desktop, click on Start Æ Programs Æ PCommLite2.5 Æ Terminal

Configuration by Telnet Console
You may use Telnet to access the EDS-728’s console utility over a network. To be able to access
the EDS’s functions over the network (by Telnet or Web Browser) from a PC host that is
connected to the same LAN as the EDS-728, you need to make sure that the PC host and the
EDS-728 are on the same logical subnetwork. To do this, check your PC host’s IP address and
subnet mask. By default, the EDS-728’s IP address is 192.168.127.253 and the EDS-728’s subnet
mask is 255.255.0.0 (for a Class B network). If you do not change these values, and your PC
host’s subnet mask is 255.255.0.0, then its IP address must have the form 192.168.xxx.xxx. On the
other hand, if your PC host’s subnet mask is 255.255.255.0, then its IP address must have the form
192.168.127.xxx.
NOTE
To use the EDS-728’s management and monitoring functions from a PC host connected to the
same LAN as the EDS-728, you must make sure that the PC host and the EDS-728 are on the
same logical subnetwork.
NOTE
Before accessing the console utility via Telnet, first connect one of the EDS-728’s RJ45 Ethernet
ports to your Ethernet LAN, or directly to your PC’s Ethernet NIC. You can establish a
connection with either a straight-through or cross-over Ethernet cable.
NOTE
The EDS-728’s default IP is 192.168.127.253.
Follow the steps below to access the console utility via Telnet.
1. Click on Start Æ Run, and then telnet to the EDS-728’s IP address from the Windows Run
window. (You may also issue the telnet command from the MS-DOS prompt.)
2. Type 1 to choose ansi/vt100, and then press Enter.
EDS-728 Series User’s Manual Getting Started

3. The Console login screen will appear. Press Enter to open the Account pop-up selector and
then select either admin or user. Use the keyboard’s down arrow to move the cursor to the
Password field, enter the Console Password (this is the same as the Web Browser password;
leave the Password field blank if a console password has not been set), and then press Enter.
NOTE
The Telnet Console looks and operates in precisely the same manner as the RS-232 Console.
Configuration by Web Browser
The Moxa EDS-728’s web browser interface provides a convenient way to modify the switch’s
configuration and access the built-in monitoring and network administration functions. The
recommended web browser is Microsoft Internet Explorer 5.5 or 6.0 with JVM (Java Virtual
Machine) installed.
NOTE
To use the EDS-728’s management and monitoring functions from a PC host connected to the
same LAN as the EDS-728, you must make sure that the PC host and the EDS-728 are on the
same logical subnetwork.
NOTE
If the EDS-728 is configured for other VLAN settings, you must make sure your PC host is on
the management VLAN. Refer to the “Configuring 802.1Q VLAN” in Chapter 3 for the VLAN
settings.
NOTE
Before accessing the EDS-728’s web browser interface, first connect one of its RJ45 Ethernet
ports to your Ethernet LAN, or directly to your PC’s Ethernet NIC. You can establish a
connection with either a straight-through or cross-over Ethernet cable.
NOTE
The EDS-728’s default IP is 192.168.127.253.

Chapter 3 Featured Functions
This chapter explains how to access the EDS-728’s various configuration, monitoring, and
administration functions. There are three ways to access these functions: RS-232 console, Telnet
console, and web browser. The serial console connection method, which requires using a short
serial cable to connect the EDS-728 to a PC’s COM port, can be used if you do not know IP
address for the EDS-728. The Telnet console and web browser connection methods can be used to
access the EDS-728 over an Ethernet LAN, or over the Internet.
The Web Console is the most user-friendly way to configure the EDS-728. In this chapter, we use
the Web Console interface to introduce the functions. There are only a few differences between the
Web Console, Serial Console, and Telnet Console.
The following topics are covered in this chapter:

Accessible IP
The EDS-728 uses an IP address-based filtering method to control access to EDS-728 units.
Accessible IP Settings allows you to add or remove “Legal” remote host IP addresses to prevent
unauthorized access. Access to the EDS-728 is controlled by IP address. That is, if a host’s IP
address is in the accessible IP table, then the host will be allowed access to the EDS-728. You can
allow one of the following cases by setting this parameter:
y Only one host with the specified IP address can access the EDS-728
E.g., enter “192.168.1.1/255.255.255.255” to allow access to just the IP address 192.168.1.1.
y Any host on a specific subnetwork can access the EDS-728
E.g., enter “192.168.1.0/255.255.255.0” to allow access to all IPs on the subnetwork defined
by this IP address/subnet mask combination.
y Any host can access the EDS-728
Disable this function by not checkmarking the “Enable the accessible IP list” checkbox.
The following table shows additional configuration examples:

Using Port Trunking
Link Aggregation allows one or more links to be aggregated together to form a Link Aggregation
Group. A MAC client can treat Link Aggregation Groups as if they were a single link.
The EDS-728’s Port Trunking feature allows devices to communicate by aggregating up to four
links in parallel, with a maximum of eight ports for each link. If one of the eight ports fails, the
other seven ports will provide back up and share the traffic automatically.
Port trunking can be used to combine up to eight ports between two EDS-728 switches. If all ports
on both switch units are configured as 100BASE-TX and they are operating in full duplex, the
potential bandwidth of the connection will be 1600 Mbps.
The Port Trunking Concept
The EDS-728 allows a maximum of 4 trunk groups, with a maximum of 8 trunk ports for each
trunk group. You can configure the trunk group to be “Static” or “LACP.” Once the trunk group is
set to “LACP,” all of the ports making up that group will be set to LACP enabled. The ports in the
“Static” trunk groups, and all the non-trunk ports that do not belong to any trunk group, will be set
to LACP disabled. When the port is set to LACP enabled, it will exchange LACPDU with its link
partner, and will result in “Forwarding.” If all of the ports in the same group are “Blocked” or
“Disabled” or “Down” (link-down), the trunk group will not work, and the user will see “LACP
Failed” for that trunk group in the user interface.
Port Trunking applies to connections between backbone devices as well as to connections in other
network areas where traffic bottlenecks exist. Port Trunking provides the following benefits:
y Gives you more flexibility in setting up your network connections, since the bandwidth of a
link can be expanded to 8 times the original bandwidth.
y Load sharing—MAC Client traffic may be distributed across multiple links.
Keep the following points in mind when configuring port trunking:
y To avoid broadcast storms or loops in your network while configuring a trunk, first disable
or disconnect all ports that you want to add to the trunk or remove from the trunk. After you
finish configuring the trunk, enable or re-connect the ports.
y Up to 4 port trunking groups (designated Trk1, Trk2, Trk3, Trk4) can be used for each
EDS-728.
y Up to 8 ports can be inserted into each port trunk group. The EDS-728 allows a maximum of
4 “Standby” ports for each LACP trunk group. In another words, a maximum of 12 ports can
belong to each LACP trunk group.
y The same transmission speed must be assigned to all ports belonging to one port trunking
group. E.g., 100M Full, 100M Half, 10M Full, or 10M Half. The auto-negotiation function
should be disabled for these ports.

y Full duplex operation only—Link Aggregation is supported only on point-to-point links with
MACs operating in full duplex mode.
y Multipoint Aggregations—The mechanisms specified in this clause do not support
aggregations among more than two systems.
When you activate port trunking settings, some advanced functions will either be set to factory
default values, or disabled:
y Port stat, such as transmitting speed, duplex, and flow control will be set to the factory
defaults.
y Communication Redundancy will be set to the factory default.
y 802.1Q VLAN will be set to the factory default and will be disabled.
y Multicast Filtering will be set to the factory default.
y Port Lock will be set to the factory default and will be disabled.
y Set Device IP will be set to the factory default
y Mirror Port will be set to the factory default and will be disabled.
Configuring Port Trunking
The Port Trunking Settings page is used to assign ports to a Trunk Group.
Step 1: Select Trk1, Trk2, Trk3, or Trk 4 from the Trunk Group drop-down box.
Step 2: Select Static or LACP from the Trunk Type drop-down box.
Step 3: Under Member Ports and Available Ports, checkmark to select specific ports.
Step 4: Use the Up / Down buttons to add/remove designated ports to/from a trunk group.
