Warnings and Notes
These are how warnings and notes are shown in this User’s Guide.
Warnings tell you about things that could harm you or your device.
Note: Notes tell you other important information (for example, other things you may need to configure or helpful tips) or recommendations.
Syntax Conventions
•The MGS-3712 and MGS-3712F models may be referred to as the “Switch”, the “device”, the “system” or the “product” in this User’s Guide.
•Product labels, screen names, field labels and field choices are all in bold font.
•A key stroke is denoted by square brackets and uppercase text, for example, [ENTER] means the “enter” or “return” key on your keyboard.
•“Enter” means for you to type one or more characters and then press the [ENTER] key. “Select” or “choose” means for you to use one of the predefined choices.
•A right angle bracket ( > ) within a screen name denotes a mouse click. For example, Maintenance > Log > Log Setting means you first click Maintenance in the navigation panel, then the Log sub menu and finally the Log Setting tab to get to that screen.
•Units of measurement may denote the “metric” value or the “scientific” value. For example, “k” for kilo may denote “1000” or “1024”, “M” for mega may denote “1000000” or “1048576” and so on.
•“e.g.,” is a shorthand for “for instance”, and “i.e.,” means “that is” or “in other words”.

This chapter introduces the main features and applications of the Switch.
The MGS-3712 and MGS-3712F are layer 2 stand-alone Gigabit Ethernet (GbE) switches.
The MGS-3712 has four GbE dual personality interfaces with each interface comprising one mini-GBIC slot and one 100/1000 Mbps RJ-45 port, with either port or slot active at a time. In addition, the MGS-3712 has 8 100/1000 Mbps RJ45 ports.
The MGS-3712F also has four GbE dual personality interfaces with each interface comprising one mini-GBIC slot and one 100/1000 Mbps RJ-45 port, with either port or slot active at a time. In addition, the MGS-3712F has 8 mini-GBIC slots.
With its built-in web configurator, managing and configuring the Switch is easy. In addition, the Switch can also be managed via Telnet, any terminal emulator program on the console port, or third-party SNMP management.
This section shows a few examples of using the Switch in various network environments.
See Chapter 42 on page 357 for a full list of software features available on the Switch.
The Switch is an ideal solution for small networks where rapid growth can be expected in the near future. The Switch can be used standalone for a group of heavy traffic users. You can connect computers and servers directly to the Switch’s port or connect other switches to the Switch.

Chapter 1 Getting to Know Your Switch
In this example, all computers can share high-speed applications on the server. To expand the network, simply add more networking devices such as switches, routers, computers, print servers etc.
Figure 1 Backbone Application
In this example application the Switch connects different company departments (RD and Sales) to the corporate backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks. All users that need high bandwidth can connect to high-speed department servers via the Switch. You can provide a super-fast uplink connection by using a Gigabit Ethernet/mini-GBIC port on the Switch.
Moreover, the Switch eases supervision and maintenance by allowing network managers to centralize multiple servers at a single location.

Chapter 1 Getting to Know Your Switch
The Switch is ideal for connecting two networks that need high bandwidth. In the following example, use trunking to connect these two networks.
Switching to higher-speed LANs such as ATM (Asynchronous Transmission Mode) is not feasible for most people due to the expense of replacing all existing Ethernet cables and adapter cards, restructuring your network and complex maintenance. The Switch can provide the same bandwidth as ATM at much lower cost while still being able to use existing adapters and switches. Moreover, the current LAN structure can be retained as all ports can freely communicate with each other.
Figure 3 High Performance Switched Workgroup Application
A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks. Stations on a logical network belong to one group. A station can belong to more than one group. With VLAN, a station cannot directly talk to or hear from stations that are not in the same group(s) unless such traffic first goes through a router.
For more information on VLANs, refer to Chapter 9 on page 95.
1.1.4.1 Tag-based VLAN Example
Ports in the same VLAN group share the same frame broadcast domain thus increase network performance through reduced broadcast traffic. VLAN groups can be modified at any time by adding, moving or changing ports without any recabling.

Chapter 1 Getting to Know Your Switch
Shared resources such as a server can be used by all ports in the same VLAN as the server. In the following figure only ports that need access to the server need to be part of VLAN 1. Ports can belong to other VLAN groups too.
Figure 4 Shared Server Using VLAN Example
Use any of the following methods to manage the Switch.
•Web Configurator. This is recommended for everyday management of the Switch using a (supported) web browser. See Chapter 5 on page 57.
•Command Line Interface. Line commands offer an alternative to the web configurator and in some cases are necessary to configure advanced features. See the CLI Reference Guide.
•FTP. Use FTP for firmware upgrades and configuration backup/restore. See Section 33.8 on page 301.
•SNMP. The Switch can be monitored by an SNMP manager. See Section 34.3 on page 306.
•Cluster Management. Cluster Management allows you to manage multiple switches through one switch, called the cluster manager. See Chapter 37 on page 335.
Do the following things regularly to make the Switch more secure and to manage the Switch more effectively.
•Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.

Chapter 1 Getting to Know Your Switch
•Write down the password and put it in a safe place.
•Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the Switch to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the Switch. You could simply restore your last configuration.

Hardware Installation and
Connection
This chapter shows you how to install and connect the Switch.
The Switch can be placed on a desktop or rack-mounted on a standard EIA rack. Use the rubber feet in a desktop installation and the brackets in a rack-mounted installation.
Note: For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front and 3.4 inches (8 cm) at the back of the Switch. This is especially important for enclosed rack installations.
1Make sure the Switch is clean and dry.
2Set the Switch on a smooth, level surface strong enough to support the weight of the Switch and the connected cables. Make sure there is a power outlet nearby.
3Make sure there is enough clearance around the Switch to allow air circulation and the attachment of cables and the power cord.
4Remove the adhesive backing from the rubber feet.

Chapter 2 Hardware Installation and Connection
5Attach the rubber feet to each corner on the bottom of the Switch. These rubber feet help protect the Switch from shock or vibration and ensure space between devices when stacking.
Figure 5 Attaching Rubber Feet
Note: Do NOT block the ventilation holes. Leave space between devices when stacking.
The Switch can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other equipment. Follow the steps below to mount your Switch on a standard EIA rack using a rack-mounting kit.
2.3.1Rack-mounted Installation Requirements
•Two mounting brackets.
•Eight M3 flat head screws and a #2 Philips screwdriver.
•Four M5 flat head screws and a #2 Philips screwdriver.
Failure to use the proper screws may damage the unit.
2.3.1.1Precautions
•Make sure the rack will safely support the combined weight of all the equipment it contains.
•Make sure the position of the Switch does not make the rack unstable or topheavy. Take all necessary precautions to anchor the rack securely before installing the unit.
