2-1. Starting switch Up
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 Note: If you have no modules, please skip this section.
• Connecting the SFP Module to the Chassis:
The optional SFP modules are hot swappable, so you can plug or unplug it 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
seated 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)
Fig. 2-1 Installation of Optional SFP Fiber Transceive
5. Have the power ON after the above procedures are done
8
• TP Port and Cable Installation
⇒ In the switch, TP port supports MDI/MDI-X auto-crossover, so both types of
cable, straight-through (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 1, 2, 3, 6 in 10/100M TP; 1, 2, 3, 4, 5, 6, 7, 8 to 1, 2, 3, 4, 5, 6, 7, 8 in Gigabit TP) and crossed-over (Cable pi n-outs for R J-45 jack 1, 2, 3, 6 to 3, 6, 1, 2) 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
Gigabit 10/100/1000 TP 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 immediately and then all off except the power LED still keeps on. This represents a reset of the system.
• Firmware Loading
After resetting, the bootloader 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. 19-Inch Wiring Closet Rail Installing
Fig. 2-2
Caution: Allow a proper spacing and proper air ventilation for the cooling fan
at both sides of the chassis.
⇒ Wear a grounding device for electrostatic discharge. ⇒ Screw the mounting accessory to the front side of the switch (See Fig. 2-2). ⇒ Place the Chassis into the 19-inch wiring closet rail and locate it at the proper
position. Then, fix the Chassis by screwing it.
2-1-3. 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.
10
2-1-3-1. TP Ports Cabling
⇒ 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.
2-1-3-2. 1000SX/LX SFP Module Cabling
It is more complex and comprehensive contrast to TP cabling in the fiber media. Basically, there are two categories of fiber, multi mode (MM) and single mode (SM). The later is categorized into several classes by the distance it supports. They are SX, LX, LHX, XD, and ZX. From the viewpoint of connector type, there mainly are LC and BIDI LC.
⎯ Gigabit Fiber with multi-mode LC SFP module
⎯ Gigabit Fiber with single-mode LC SFP module
⎯ Gigabit Fiber with BiDi LC 1310nm SFP module
⎯ Gigabit Fiber with BiDi LC 1550nm SFP module
The following table lists the types of fiber that we support and those else not listed here are available upon request.

2-1-3-3. Switch Cascading 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: 11.12/m Cat. 5 TP Wire: 1.12/m Fiber Cable: 1.0/m
Fiber Cable : 10.10/m TP to fiber Converter: 56 Bit Time unit : 1ns (1sec./1000 Mega bit)
Bit Time unit: 0.01μs (1sec./100 Mega bit)
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 connection.
• 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 improve 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 requireme nts are applied.

Case1: All switch ports are in the same local area network. Every port can access
each other (See Fig. 2-3).
Fig. 2-3 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.2-4).
Fig. 2-4 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 na mes for each VLAN groups at one switch.
13
Case 2b: Port-based VLAN (See Fig.2-5).
Fig. 2-5 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 access 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 access VLAN2 members.
Case3a: The same VLAN members can be at different switches with the same VID (See Fig. 2-6).

2-1-4. Configuring the Management Agent
We offer you three ways to startup the switch management function. They are RS-232 console, CLI, and Web. Users can use any one of them to monitor and configure the switch. You can touch them through the following procedures.
Section 2-1-4-1: Configuring through the Serial RS-232 Port Section 2-1-4-2: Configuring through the Ethernet Port Note: Please first modify the IP address, Subnet mask, Default gateway and DNS
through RS-232 console, and then do the next.

2-1-4-1. Serial RS-232 Port
To perform the configuration through RS-232 console port, the switch’s serial port must be directly connected to a DCE device, for example, a PC, through RS-232 cable with DB-9 connector. Next, run a terminal emulator with the default setting of the switch’s serial port. With this, you can communicate with the switch.
In the switch, RS-232 interface only supports baud rate 57.6k bps with 8 data bits, 1 stop bit, no parity check and no flow control.

RS-232 cable with female DB-9 connector at both ends
To configure the switch, please follow the procedures below:
1. Find the RS-232 DB-9 cable with female DB-9 connector bundled.
Normally, it just uses pins 2, 3 and 7. See also Appendix B for more details on Null Modem Cable Specifications.
2. Attaches the DB-9 female cable connector to the male serial RS-232
DB-9 connector on the switch.
3. Attaches the other end of the serial RS-232 DB-9 cable to PC’s serial
port, running a terminal emulator supporting VT100/ANSI terminal with The switch’s serial port default settings. For example, Windows98/2000/XP HyperTerminal utility.
Note: The switch’s serial port default settings are listed as follows:
Baud rate 57600 Stop bits 1 Data bits 8 Parity N Flow control none
4. When you complete the connection, then press <Enter> key. The login
prompt will be shown on the screen. The default username and password are shown as below:

• Set IP Address, Subnet Mask and Default Gateway IP Address
Please refer to Fig. 2-7 CLI Management for details about LevelOne’s setting. They are default setting of IP address. You can first either configure your PC IP address or change IP address of the switch, next to change the IP address of default gateway and subnet mask.
For example, your network address is 10.1.1.0, and subnet mask is
255.255.255.0. You can change the switch’s default IP address 192.168.1.1 to
10.1.1.1 and set the subnet mask to be 255.255.255.0. Then, choose your default gateway, may be it is 10.1.1.254.
Default Value GSW-0890 Your Network Setting IP Address
Subnet Default Gateway
After completing these settings in the switch, it will reboot to have the configuration taken effect. After this step, you can operate the management through the network, no matter it is from a web browser or Network Management System (NMS).

2-1-4-2. Ethernet Port
There are three ways to configure and monitor the switch through the switch’s Ethernet port. They are CLI, Web browser and SNMP manager. The user interface for the last one is NMS dependent and does not cover here. We just introduce the first two types of management interface.
GSW-0890 L2 Managed Switch Default IP Setting: IP = 192.168.1.1 Subnet Mask = 255.255.255.0 Default Gateway = 192.168.1.254

• Managing 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 the switch and a PC by a qualified 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. 2-9 about the switch’s default IP address information.
2. Run CLI or web browser and follow the menu. Please refer to Chapter 3 and Chapter 4.

2-1-5. 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 looks is shown in the Fig. 2-11. 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.
32 bits
Network identifier Host identifier

With the classful addressing, it divides IP address 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, 192.168.1.0/24. 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.
Bit # 0 1 7 8
0
Network address Host address
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.
Bit # 01 2 15 16
10
Network address Host address
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.
Bit # 0 1 2 3 23 24 31

Network address Host

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 --- 192.168.25 5.255
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 .
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 t he network itself, and all 1s mean IP broadcast.
128.1.2.128/25
10000000.00000001.00000010.1 0000000
25 bits
All 0s = 128.1.2.128
All 1s= 128.1.2.255
21
SubneNetwork
1 0000000 1 1111111
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.
Prefix Length No. of IP matched No. of Addressable IP
/32 1 ­/31 2 ­/30 4 2 /29 8 6 /28 16 14 /27 32 30 /26 64 62 /25 128 126 /24 256 254 /23 512 510 /22 1024 1022 /21 2048 2046 /20 4096 4094 /19 8192 8190 /18 16384 16382 /17 32768 32766 /16 65536 65534
Table 2-4
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.
