2. Installation
2-1. Starting 8 Port Gigabit Ethernet 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 to the switch
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
Fig. 2-1 Installation of Optional SFP Fiber Transceive
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

MICROSENS 8 Port Gigabit Ethernet Switch User’s Manual
• 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 pin-outs for RJ-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. Installing Chassis to a 19-Inch Wiring Closet Rail
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.
11
MICROSENS 8 Port Gigabit Ethernet Switch User’s Manual
2-1-3-1. 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.
2-1-3-2. Cabling Requirements for 1000SX/LX SFP Module
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

2-1-3-3. 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: 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 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 requirements are
applied.

MICROSENS 8 Port Gigabit Ethernet Switch User’s Manual
Case1: All switch ports are in the same local area network. Every port can access each other
(See Fig. 2-3).
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 portbased 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. 2-3 No VLAN Configuration 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.

14
MICROSENS 8 Port Gigabit Ethernet Switch User’s Manual
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).

2-1-4-1. Configuring the Management Agent of 8 Port Gigabit Ethernet Switch
through the 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.

• Set IP Address, Subnet Mask and Default Gateway IP Address
Please refer to Fig. 2-7 CLI Management for details about the ex-factory 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.

through the 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.

• Managing 8 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 the switch and a PC by a qualified UTP
Cat. 5 cable with RJ-45 connector.
Ethernet LAN
Fig. 2-9
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.

MICROSENS 8 Port Gigabit Ethernet Switch User’s Manual
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.

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.

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.

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:
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.
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
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 2-4
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 subnetted 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.
23
MICROSENS 8 Port Gigabit Ethernet Switch User’s Manual
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. The gateway setting is used for Trap Events Host only in the switch.
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. 2-12
First, IP Address: as shown in the Fig. 2-12, 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. 2-12, enter “255.255.255.0”. Any subnet mask
such as 255.255.255.x is allowable in this case.
DNS:
The Domain Name Server translates human readable machine name to IP address. Every
machine on the Internet has a unique IP address. A server generally has a static IP address. To
connect to a server, the client needs to know the IP of the server. However, user generally uses
the name to connect to the server. Thus, the switch DNS client program (such as a browser) will
ask the DNS to resolve the IP address of the named server.
