Web Managed GbE Switch

Chapter 1 Introduction to the Web Smart Switch

1.1 General Description

High Performance

The device is a powerful, high-performance Gigabit Ethernet switch with 24 10/100/1000 Mbps ports, providing you a cost-effective, space-saving solution for expanding your network. The gigabit ports can lead you to a real gigabit connection, making you be able to transfer high bandwidth-needed files higher and faster in an easy way. This device provides the easy management function through the Ethernet Web. The network administrator can configure the status and the port function setting of the device through the Web-Based UI. When installing the auto-discovery management tool helps network managers to search and access those switches on LAN easily. Therefore, network managers can access switches that support auto-discovery on LAN without memorizing IP address.

Smart Features

The device provides rich features including Link Aggregation, VLANs, IGMP Snooping, Port Trunking, Spanning Tree, Security and other network management to meet the requirements evolving medium and small-sized enterprises. QoS secures the bandwidth for some bandwidth-demanded applications including VoIP or video conference. Additionally, IEEE 802.3az Energy Efficient Ethernet ability is supported to promise operation in Low Power Idle Mode and save power consumption.

Easy Installation and Management

This switch is plug & play and hassle-free in installation. Auto-MDI/MDI-X crossover on all ports eliminates the need for crossover cables for connection to another switch or hub. Auto-Negotiation on each port senses the link speed of a network device and intelligently adjusts for compatibility and optimal performance. This switch also features diagnostic LEDs, which display the status and activities of the network.

The following figure shows the rear panel of the switch:

Power Receptacle To be compatible with the electric service standards around the world, the switch is designed to

afford the power supply in the range from 100 to 240 VAC, 50/60 Hz. Please make sure that your outlet standard to be within this range. To power on the switch, please plug the female end of the power cord firmly into the receptacle of the switch, the other end into an electric service outlet, and use the POWER ON/OFF switch to have

the Switch power on or off. After the switch powered on, please check if the power LED is lit for a

normal power status.

1.5 Installation

This switch can be placed on your desktop directly, or mounted in a rack. Please refer to the instructions for installation.

Before installing the switch, we recommend:

1. The switch is placed with appropriate ventilation environment. A minimum 25 mm space around the unit is recommended.

2. The switch and the relevant components are away from sources of electrical noise such as radios, transmitters and broadband amplifiers

3. The switch is away from environments beyond recommend moisture

Desktop Installation

1. Install the switch on a level surface that can support the weight of the unit and the relevant

components.

2. Plug the switch with the female end of the provided power cord and plug the male end to the

power outlet.

Rack-mount Installation

The switch may be standalone, or mounted in a rack. Rack mounting facilitate to an orderly installation when you are going to install series of networking devices.

Procedures to Rack-mount the switch:

1. Disconnect all the cables from the switch before continuing.

2. Place the unit the right way up on a hard, flat surface with the front facing you.

3. Locate a mounting bracket over the mounting holes on one side of the unit.

4. Insert the screws and fully tighten with a suitable screwdriver.

5. Repeat the two previous steps for the other side of the unit.

6. Insert the unit into the rack and secure with suitable screws.

7. Reconnect all the cables.

Installing Network Cables

1. Crossover or straight-through cable: All the ports on the switch support Auto-MDI/MDI-X

functionality. Both straight-through or crossover cables can be used as the media to connect the switch with PCs as well as other devices like switches, hubs or router.

Management VLAN

This allows the entry of a VLAN from which a management station will be allowed to manage the device using TCP/IP (in-band via web manager or Telnet). Management stations that are on VLANs other than the one selected here will not be able to manage the Switch. The default management VLAN is VLAN 1.

Port Select

Select the port(s) from the list box that you will change the port settings for.

Enabled

Select Enable from the drop-down box to enable a port. The factory default for all ports is enabled. A port must be enabled for data transmission to occur. Select Disable to not use a port.

Speed

Port speed capabilities:

 Auto: Auto speed with all capabilities.  Auto-10M: Auto speed with 10M ability only.  Auto-100M: Auto speed with 100M ability only.  Auto-1000M: Auto speed with 1000M ability only.  Auto-10/100M: Auto speed with 10/100M ability.  10M: Force speed with 10M ability.  100M: Force speed with 100M ability.  1000M: Force speed with 1000M ability.

Selecting Auto (auto-negotiation) allows one port to negotiate with a peer port automatically to obtain the connection speed and duplex mode that both ends support. When auto-negotiation is turned on, a port on the switch negotiates with the peer automatically to determine the connection speed and duplex mode. If the peer port does not support auto-negotiation or turns off this feature, the switch determines the connection speed by detecting the signal on the cable and using half duplex mode. When the switch’s auto-negotiation is turned off, a port uses the pre-configured speed and duplex mode when making a connection, thus requiring you to make sure that the settings of the peer port are the same in order to connect.

Duplex

Port duplex capabilities:

 Auto: Auto duplex with all capabilities.  Half: Auto speed with 10/100M ability only.  Full: Auto speed with 10/100/1000M ability only.

Flow Control

A concentration of traffic on a port decreases port bandwidth and overflows buffer memory causing packet discards and frame losses. Flow Control is used to regulate transmission of signals to match the bandwidth of the receiving port. The switch uses IEEE802.3x flow control in full duplex mode and backpressure flow control in half duplex mode. IEEE802.3x flow control is used in full duplex mode to send a pause signal to the sending port, causing it to temporarily stop sending signals when the receiving port memory buffers fill. Back Pressure flow control is typically used in half duplex mode to send a "collision" signal to the sending port (mimicking a state of packet collision) causing the sending port to temporarily stop sending signals and resend later. Select “Enabled” to enable it. Or select “Disabled” to disable it.

Flow Control Config

The Config column displays if Flow Control has been configured to be turned On or Off for the port.

Flow Control Status

The column displays the port’s current Flow Control status.

3.3.2 Port Mirroring

The Mirror function copies all the packets that are transmitted by the source port to the destination port. It allows administrators to analyze and monitor the traffic of the monitored ports.

The Mirror Configuration steps are as follows: Click Switching > Mirror > Local Mirror Setting in the navigation panel to display the screen as shown below.
