2. Installation

2-1. Starting up 24 Port Gigabit Ethernet Switch

This section will give users a quick start for:

- Hardware and Cable Installation

- Management Station Installation

- Software booting and configuration

2-1-1. Hardware and Cable Installation

At the beginning, please do first:

Wear a grounding device to avoid the damage from electrostatic discharge Be sure that power switch is OFF before you insert the power cord to power source

• Installing optional SFP fiber transceivers to the 24 Port Gigabit Ethernet PoE

Switch

Note: If you have no modules, please skip this section.

Fig. 2-1 Installation of optional SFP transceiver

• Connecting the SFP Module to the Chassis:

The optional SFP modules are hot swappable, so you can plug or unplug them before or after powering on.

1. Verify that the SFP module is the right model and conforms to

the chassis

2. Slide the module along the slot. Also be sure that the module is properly seat-

ed against the slot socket/connector

3. Install the media cable for network connection

4. Repeat the above steps, as needed, for each module to be installed into slot(s)

5. Have the power ON after the above procedures are done

24 Port Gigabit Ethernet PoE Switch – User Manual Page 6 of 72 ________________________________________________________________________

• TP Port and Cable Installation

In the switch, TP ports support MDI/MDI-X auto-crossover, so both types of cable,

straight-through and crossed-over can be used. It means you do not have to tell from them, just plug it.

Use Cat. 5 grade RJ-45 TP cable to connect to a TP port of the switch and the other

end is connected to a network-aware device such as a workstation or a server.

Repeat the above steps, as needed, for each RJ-45 port to be connected to a

10/100/1000Base-T device.

Now, you can start having the switch in operation.

• Power On

The switch supports 100-240 VAC, 50-60 Hz power supply. The power supply will automatically convert the local AC power source to DC power. It does not matter whether any connection plugged into the switch or not when power on, even modules as well. After the power is on, all LED indicators will light up and then all off except the power LED still keeps on. This represents a reset of the system.

• Firmware Loading

After resetting, the boot loader will load the firmware into the memory. It will take about 30 seconds, after that, the switch will flash all the LED once and automatically performs self-test and is in ready state.

2-1-2. Cabling Requirements

To help ensure a successful installation and keep the network performance good, please take a care on the cabling requirement. Cables with worse specification will render the LAN to work poorly.

2-1-2-1. Cabling Requirements for TP Ports

For Fast Ethernet TP network connection

The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 100

meters.

Gigabit Ethernet TP network connection

The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 100

meters. Cat. 5e is recommended.

2-1-2-2. Cabling Requirements for 1000Base-SX/LX SFP Modules

It is more complex and comprehensive contrast to TP cabling in the fiber media. Basically, there are two categories of fiber, Multimode (MM) and Single Mode (SM). From the viewpoint of connector type, there mainly are LC (standard) and BIDI SC.

The following table lists the types of fiber that we support and those else not listed here are available upon request.

2-1-2-3. Switch Cascading in Topology

• Takes the Delay Time into Account

Theoretically, the switch partitions the collision domain for each port in switch cascading that you may up-link the switches unlimitedly. In practice, the network extension (cascading levels & overall diameter) must follow the constraint of the IEEE

802.3/802.3u/802.3z and other 802.1 series protocol specifications, in which the limitations are the timing requirement from physical signals defined by 802.3 series specification of Media Access Control (MAC) and PHY, and timer from some OSI layer 2 protocols such as 802.1d, 802.1q, LACP and so on.

The fiber, TP cables and devices’ bit-time delay (round trip) are as follows:

1000Base-X TP, Fiber

100Base-TX TP

100Base-FX Fiber

Round trip Delay: 4096

Round trip Delay: 512

Cat. 5 TP Wire

Fiber Cable

1.0/m Fiber Cable

10.10/m

TP to fiber Converter: 56

Bit Time unit: 1ns (1sec./1000 M bit)

Bit Time unit: 0.01 s (1sec./100 Mbit)

Table 2-2

Sum up all elements’ bit-time delay and the overall bit-time delay of wires/devices must be within Round Trip Delay (bit times) in a half-duplex network segment (collision domain). For full-duplex operation, this will not be applied. You may use the TP-Fiber module to extend the TP node distance over fiber optic and provide the long haul conne ction.

24 Port Gigabit Ethernet PoE Switch – User Manual Page 8 of 72 ________________________________________________________________________

• Typical Network Topology in Deployment

A hierarchical network with minimum levels of switch may reduce the timing delay between server and client station. Basically, with this approach, it will minimize the number of switches in any one path; will lower the possibility of network loop and will i mprove network efficiency. If more than two switches are connected in the same network, select one switch as Level 1 switch and connect all other switches to it at Level 2. Server/Host is recommended to connect to the Level 1 switch. This is general if no VLAN or other special requirements are applied. Case1: All switch ports are in the same local area network. Every port can access each other (See Fig. 2-2) *

Fig. 2-2 No VLAN Configuration Diagram

If VLAN is enabled and configured, each node in the network that can communicate each other directly is bounded in the same VLAN area.

Here VLAN area is defined by what VLAN you are using. The switch supports both port-based VLAN and tag-based VLAN. They are different in practical deployment, especially in physical location. The following diagram shows how it works and what the difference they are.

Case2a: Port-based VLAN (See Fig.2-3).

Fig. 2-3 Port-based VLAN Diagram

1. The same VLAN members could not be in different switches.

2. Every VLAN members could not access VLAN members each other.

3. The switch manager has to assign different names for each VLAN groups at one switch.

24 Port Gigabit Ethernet PoE Switch – User Manual Page 9 of 72 ________________________________________________________________________

Case 2b: Port-based VLAN (See Fig.2-4).

Fig. 2-4 Port-based VLAN Diagram

1. VLAN1 members could not access VLAN2, VLAN3 and VLAN4 members.

2. VLAN2 members could not access VLAN1 and VLAN3 members, but they could ac-

cess VLAN4 members.

3. VLAN3 members could not access VLAN1, VLAN2 and VLAN4.

4. VLAN4 members could not access VLAN1 and VLAN3 members, but they could ac-

cess VLAN2 members.

Case3a: The same VLAN members can be at different switches with the same VID

(See Fig. 2-5)

2-1-3. Configuring the Management Agent

In the way of web, user is allowed to startup the switch management function. Users can use any one of them to monitor and configure the switch. You can touch them through the following procedures described in section 2-1-3-1.

2-1-3-1. Configuring Management Agent

For complete configuration and monitoring a web browser has to be used. Basic information can be obtained using a SNMP manager. Web-based UI for the switch is an interface in a highly friendly way.

Fig. 2-6 IP Configuration

• Managing 24 Port Gigabit Ethernet Switch through Ethernet Port

Before you communicate with the switch, you have to finish first the configuration of the IP address or to know the IP address of the switch. Then, follow the procedures listed below.

1. Set up a physical path between the configured switch and a PC by a quali-

fied UTP Cat. 5 cable with RJ-45 connector.

Note: If PC directly connects to the switch, you have to setup the same

subnet mask between them. But, subnet mask may be different for the PC in the remote site. Please refer to Fig. 2-6 about the default IP address information.

2. Run web browser and follow the menu. Please refer to Chapter 3.

Fig. 2-7 the Login Screen for Web

24 Port Gigabit Ethernet PoE Switch Default IP Setting: IP = 192.168.1.1 Subnet Mask = 255.255.255.0 Default Gateway = 192.168.1.254

Assign a reasonable IP address, For example: IP = 192.168.1.100 Subnet Mask = 255.255.255.0 Default Gateway = 192.168.1.254

Ethernet LAN

24 Port Gigabit Ethernet PoE Switch – User Manual Page 11 of 72 ________________________________________________________________________

2-1-4. IP Address Assignment

For IP address configuration, there are three parameters needed to be filled in. They are IP address, Subnet Mask, Default Gateway and DNS.

IP address:

The address of the network device in the network is used for internetworking communication. Its address structure is shown Fig. 2-8. It is “classful” because it is split into predefined address classes or categories.

Each class has its own network range between the network identifier and host identifier in the 32 bits address. Each IP address comprises two parts: network identifier (address) and host identifier (address). The former indicates the network where the addressed host resides, and the latter indicates the individual host in the network which the address of host refers to. And the host identifier must be unique in the same LAN. Here the term of IP address we used is version 4, known as IPv4.

Network identifier

Host identifier

Fig. 2-8 IP address structure

With the classful addressing, it divides IP addresses into three classes, class A, class B and class C. The rest of IP addresses are for multicast and broadcast. The bit length of the network prefix is the same as that of the subnet mask and is denoted as IP address/X, for example, 192.168.1.0/10. Each class has its address range described below.

Class A:

Address is less than 126.255.255.255. There are a total of 126 networks can be defined because the address 0.0.0.0 is reserved for default route and 127.0.0.0/8 is reserved for loopback function.

Class B:

IP address range between 128.0.0.0 and 191.255.255.255. Each class B network has a 16-bit network prefix followed 16-bit host address. There are 16,384 (2^14)/16 networks able to be defined with a maximum of 65534 (2^16 –2) hosts per network.

24 Port Gigabit Ethernet PoE Switch – User Manual Page 12 of 72 ________________________________________________________________________

Class C:

IP address range between 192.0.0.0 and 223.255.255.255. Each class C network has a 24-bit network prefix followed 8-bit host address. There are 2,097,152 (2^21)/24 networks able to be defined with a maximum of 254 (2^8 –2) hosts per network.

110

Class D and E:

Class D is a class with first 4 MSB (Most significance bit) set to 1-1-1-0 and is used for IP Multicast. See also RFC 1112. Class E is a class with first 4 MSB set to 1-1-1-1 and is used for IP broadcast.

According to IANA (Internet Assigned Numbers Authority), there are three specific IP address blocks reserved and able to be used for extending internal network. We call it Private IP address and list below:

Class A

10.0.0.0 --- 10.255.255.255

Class B

172.16.0.0 ---

172.31.255.255

Class C

192.168.0.0 ---

192.168.255.255

Please refer to RFC 1597 and RFC 1466 for more information.

Subnet mask:

It means the sub-division of a class-based network or a CIDR block. The subnet is used to determine how to split an IP address to the network prefix and the host address in bitwise basis. It is designed to utilize IP address more efficiently and ease to manage IP network.

For a class B network, 128.1.2.3, it may have a subnet mask 255.255.0.0 in default, in which the first two bytes is with all 1s. This means more than 60 thousands of nodes in flat IP address will be at the same network. It’s too large to manage practically. Now if we divide it into smaller network by extending network prefix from 16 bits to, say

24 bits, that’s using its third byte to subnet this class B network. Now it has a subnet

mask 255.255.255.0, in which each bit of the first three bytes is 1. It’s now clear that the first two bytes is used to identify the class B network, the third byte is used to identify the subnet within this class B network and, of course, the last byte is the host number.

Bit # 0 1 2 3 23 24 31

Network address Host address

24 Port Gigabit Ethernet PoE Switch – User Manual Page 13 of 72 ________________________________________________________________________

Not all IP address is available in the sub-netted network. Two special addresses are reserved. They are the addresses with all zero’s and all one’s host number. For example, an IP address 128.1.2.128, what IP address reserved will be looked like? All 0s mean the network itself, and all 1s mean IP broadcast.

In this diagram, you can see the subnet mask with 25-bit long, 255.255.255.128, contains 126 members in the sub-netted network. Another is that the length of network prefix equals the number of the bit with 1s in that subnet mask. With this, you can easily count the number of IP addresses matched. The following table shows the result.

Table 2-3

According to the scheme above, a subnet mask 255.255.255.0 will partition a network with the class C. It means there will have a maximum of 254 effective nodes existed in this sub-netted network and is considered a physical network in an autonomous network. So it owns a network IP address which may looks like 168.1.2.0.

With the subnet mask, a bigger network can be cut into small pieces of network. If we want to have more than two independent networks in a worknet, a partition to the network must be performed. In this case, subnet mask must be applied.

For different network applications, the subnet mask may look like 255.255.255.240.

This means it is a small network accommodating a maximum of 15 nodes in the network.

Default gateway:

For the routed packet, if the destination is not in the routing table, all the traffic is put into the device with the designated IP address, known as default router. Basically, it is a routing policy.

For assigning an IP address to the switch, you just have to check what the IP address of the network will be connected with the switch. Use the same network address and append your host address to it.

Fig. 2-8

First, IP Address: as shown in the Fig. 2-9, enter “192.168.1.1”, for instance. For sure, an IP address such as 192.168.1.x must be set on your PC.

Second, Subnet Mask: as shown in the Fig. 2-9, enter “255.255.255.0”. Any sub- net mask such as 255.255.255.x is allowable in this case.

3. Operation of

Web-based Management

This chapter would introduce how to manage your Web Smart Switch and how to configure the 10/100/1000Mbps TP Ports and Gigabit SFP Fiber ports on the switch via web user interfaces. The Web Smart Switch provides 20 fixed Gigabit Ethernet TP ports and 4 Gigabit dual media ports. With this facility, you can easily access and monitor the status like port activity and multicast traffic through any ports on the switch.

The default values are listed in the table below:

IP Address

192.168.1.1

Subnet Mask

255.255.255.0

Default Gate-

way

192.168.1.253

Password

admin

Table 3-1

When the configuration of your switch is finished, you can browse it by the IP address you set up. For instance, type http://192.168.1.1 in the address row in a browser, then the following screen (see Fig.4-1) would show up and ask for your password input for login and access authentication. The default password is “admin”. For the first time access, please enter the default password, and click <Apply> button. The login process now would be completed.

Web Smart Switch supports a simplified user management function which allows

only one administrator to configure the switch at one time.

To optimize the display effect, we recommend Microsoft IE and 1024x768 display

resolution.
