1.2 Example Applications

This section shows a few examples of using the Switch in various network environments. Note that the Switch in the figure is just an example Switch and not your actual Switch.

1.2.1 PoE Example Application

The Switch can supply PoE (Power over Ethernet) to Powered Devices (PDs) such as an IP camera, a wireless router, an IP telephone and a general outdoor router that are not within reach of a power outlet.

GS1900 Series User’s Guide

17

Chapter 1 Getting to Know Your Switch

Figure 1 PoE Example Application

1.2.2 Backbone Example Application

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.

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, and so on.

Figure 2 Backbone Example Application

1.2.3 Bridging / Fiber Uplink 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/SFP port on the Switch.

GS1900 Series User’s Guide

Chapter 1 Getting to Know Your Switch

Figure 3 Bridging / Fiber Uplink Example Application

1.2.4 Gigabit Ethernet to the Desktop

The Switch is an ideal solution for small networks which demand high bandwidth 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.

In this example, all computers can share high-speed applications on the server and access the Internet. To expand the network, simply add more networking devices such as switches, routers, computers, print servers and so on.

Figure 4 Gigabit to the Desktop

1.2.5 IEEE 802.1Q VLAN Application Example

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 or more groups. With VLAN, a station cannot

GS1900 Series User’s Guide

19

Chapter 1 Getting to Know Your Switch

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 74.

1.2.5.1 Tag-based VLAN Example

Ports in the same VLAN group share the same frame broadcast domain, thus increasing network performance by reducing broadcast traffic. VLAN groups can be modified at any time by adding, moving or changing ports without any re-cabling.

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 5 Shared Server Using VLAN Example

1.2.6 IPv6 Support

IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 1038 IP addresses. At the time of writing, the Switch supports the following features.

•Static address assignment and stateless auto-configuration

•Neighbor Discovery Protocol (a protocol used to discover other IPv6 devices in a network)

•Remote Management using PING, telnet, SNMP, HTTP and TFTP services

•ICMPv6 to report errors encountered in packet processing and perform diagnostic functions, such as "PING”

•IPv4/IPv6 dual stack; the Switch can run IPv4 and IPv6 at the same time

•DHCPv6 client

1.3Ways to Manage the Switch

Use any of the following methods to manage the Switch.

GS1900 Series User’s Guide

20

•Web Configurator. This is recommended for everyday management of the Switch using a (supported) web browser. See Chapter 5 on page 43.

•TFTP. Use Trivial File Transfer Protocol for firmware upgrades and configuration backup/restore. See Section 33.1 on page 229, Section 33.3 on page 232, and Section 33.4 on page 233.

•SNMP. The device can be configured by a SNMP manager. See Section 32.3 on page 215.

•ZON Utility. ZON Utility is a program designed to help you deploy and perform initial setup on a network more efficiently. See Section 4.1 on page 38.

1.4Good Habits for Managing the Switch

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 is not easy to guess and that consists of different types of characters, such as numbers and letters.

•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.

Chapter 2 Hardware Installation and Connection

CHAPTER 2

Hardware Installation and

Connection

This chapter shows you how to install and connect the Switch.

2.1 Installation Scenarios

This chapter shows you how to install and connect the Switch.

The Switch can be:

•Placed on a desktop.

•Mounted on a wall.

•Rack-mounted on a standard EIA rack.

Note: Ask an authorized technician to attach the Switch to the rack/wall. See the Installation Requirements sections in this chapter to know the types of screws and screwdrivers for wall-mounting.

WARNING! Failure to use the proper screws may damage the unit.

Make sure you connect the Switch’s power cord to a socket-outlet with an earthing connection or its equivalent.

WARNING! This Switch is not suitable for use in locations where children are likely to be present.

See Table 1 on page 17 for the comparison table of the hardware installation methods for each model.

2.2 Desktop Installation Procedure

1 Make 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.

GS1900 Series User’s Guide

22

Chapter 2 Hardware Installation and Connection

3Make sure there is at least 40 mm of clearance from the bottom to the Switch, and make sure there is enough clearance around the Switch to allow air circulation and the attachment of cables and the power cord. This is especially important for enclosed rack installations.

4Remove the adhesive backing from the rubber feet.

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 6 Attaching Rubber Feet

Note: Do NOT block the ventilation holes. Leave space between devices when stacking.

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.

2.3 Wall Mounting

You may need screw anchors if mounting on a concrete or brick wall.

2.3.1 Wall-mounted Installation Requirement

The following are the wall-mounted installation requirements:

•Use screws with 6 mm ~ 8 mm (0.24" ~ 0.31") wide heads.

•See the following table for how far apart to place the screws. Table 2 Distance between the centers of the holes for wall mounting

GS1900-8	GS1900-8HP	GS1900-10HP	GS1900-16	GS1900-24E
176 mm	176 mm	176 mm	148 mm	207 mm

The following figure shows the screw specifications used for wall mounting.

•D = 7.00 mm

•H = 2.00 mm

•L= 15.50 mm

GS1900 Series User’s Guide

23

Chapter 2 Hardware Installation and Connection

• d = 3.50 mm

Do the following to attach your Switch to a wall.

1Select a position free of obstructions on a wall strong enough to hold the weight of the Switch.

2Mark two holes on the wall at the appropriate distance apart for the screws.

WARNING! Be careful to avoid damaging pipes or cables located inside the wall when drilling holes for the screws.

3If using screw anchors, drill two holes for the screw anchors into the wall. Push the anchors into the full depth of the holes, then insert the screws into the anchors. Do not insert the screws all the way in - leave a small gap. The gap must be big enough for the screw heads to slide into the screw slots and the connection cables to run down the back of the Switch.

If not using screw anchors, use a screwdriver to insert the screws into the wall. Do not insert the screws all the way in - leave a gap.

Note: Make sure the screws are fastened well enough to hold the weight of the Switch with the connection cables.

4Align the holes on the back of the Switch with the screws on the wall. Hang the Switch on the screws.

GS1900 Series User’s Guide

24

Chapter 2 Hardware Installation and Connection

Note: Make sure there is enough clearance between the wall and the Switch to allow ventilation.

The Switch should be wall-mounted horizontally. The Switch's side panels with ventilation slots should not be facing up or down as this position is less safe.

2.4 Rack Mounting

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.

Note: Make sure there is enough clearance between each equipment on the rack for air circulation.

2.4.1 Rack-mounted Installation Requirements

The following are the rack-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.

2.4.1.1Precautions

•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 top-heavy. Take all necessary precautions to anchor the rack securely before installing the unit.

2.4.2Attaching the Mounting Brackets to the Switch

1 Position a mounting bracket on one side of the Switch, lining up the four screw holes on the bracket with the screw holes on the side of the Switch.

3.1.1 Ethernet Ports

The Switch has 1000Base-T auto-negotiating, auto-crossover Ethernet ports. In 10/100/1000 Mbps Gigabit Ethernet, the speed can be 10Mbps, 100 Mbps or 1000 Mbps. The duplex mode can be both half or full duplex at 100 Mbps and full duplex only at 1000 Mbps.

GS1900 Series User’s Guide

29

Chapter 3 Hardware Overview

An auto-negotiating port can detect and adjust to the optimum Ethernet speed (10/100/1000 Mbps) and duplex mode (full duplex or half duplex) of the connected device.

An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or crossover Ethernet cable.

3.1.1.1 Default Ethernet Settings

The factory default negotiation settings for the Ethernet ports on the Switch are:

•Speed: Auto

•Duplex: Auto

•Flow control: Off

3.1.2SFP Slots

These are slots for Small Form-Factor Pluggable (SFP) transceivers. A transceiver is a single unit that houses a transmitter and a receiver. Use a transceiver to connect a fiber-optic cable to the Switch. The Switch does not come with transceivers. You must use transceivers that comply with the Small FormFactor Pluggable (SFP) Transceiver MultiSource Agreement (MSA). See the SFF committee’s INF-8074i specification Rev 1.0 for details.

You can change transceivers while the Switch is operating. You can use different transceivers to connect to Ethernet switches with different types of fiber-optic connectors.

•Type: SFP connection interface

•Connection speed: 1 Gigabit per second (Gbps)

To avoid possible eye injury, do not look into an operating fiber-optic module’s connectors.

3.1.2.1 Transceiver Installation

Use the following steps to install a transceiver.

1Insert the transceiver into the slot with the exposed section of PCB board facing down. Figure 23 Transceiver Installation Example

2Press the transceiver firmly until it clicks into place.
