2.2 The Front Panel
2.2.1 1000BASE-T Port
1000BASE-T is primarily used for network backbone connections. Each 1000BASE-T support
1000Mbps/100Mbps/10Mbps Full-Duplex mode, which provides an Auto-Negotiation and
Auto-MDI/MDIX functions that sense for the attached device's maximum operating speed and
automatically sets the Switch to operate at that speed. Users only need to connect a network
cable into any TP port, and the functions will do the rest.
2.2.2 100BASE-TX Port
Each 100BASE-TX port provides an Auto-Negotiation function that senses 100/10Mbps
Full-/Half-Duplex and Auto-MDI/MDIX functions that sense for the attached device's maximum
operating speed and automatically sets the Switch to operate at that speed. Users only need to
connect a network device into any TP port, and the functions will do the rest.
2.2.3 Cabling Port Type Cable Type Connector
1000BASE-T Cat.5, 5E TP RJ-45
100BASE-TX Cat.5, 5E TP RJ-45
10BASE-T Category 3, 4 or 5 TP RJ-45
Note: Category 5 or 5E cable recommended whenever installing new cabling.

4 SMART FUNCTION SETTINGS
4.1 Start Smart Function
The Switch has a smart function that you can use to manage your local area network (LAN )
more effectively. You also can use the default setting to make the Switch operate as a dumb
switch.
If you want to use smart function, install the Switch as below:
．Use the “RS-232” connector to connect the Switch to a computer. Connect one (1) cable end
to the Switch, and connect the other end to the computer’s “COM1” or “COM2” port.
Note: If your Windows program doesn’t have a hyper terminal, you have to install it first.
．Power “ON” the Switch
．Execute the “HyperTerminal” program:
Start Menu ÆApplication Program ÆCommunication ÆHyper Terminal
．Setup the connection content of Hyper Terminal:
※In connection tag, select which “COM” port is used to connect PC and the Switch.
※Then press the “SETUP” button, set “Bits per second” to 19200, “Data bits” to 8, “Parity”
to None, “Stop bits” to 1, “Flow control” to None.
．After finishing the setting-up action in Hyper Terminal window, press any key to continue. Now
the computer can connect to Switch and use the user interface menu to select control function.
Note: If you also had “Term95”, it could be easy to use as the following procedures:
(a). Execute the “Term95” program;
(b). Select the “Setting” / “Line” into the ”RS232 settings” menu;
(c). RS232 settings: set as the following and select “Ok”.
Item Setting
Port COM
Baud rate 19200
Data bits 8 bits
Parity None
Stop bits 1
Flow control NA
(d). Power “ON” the Switch.

6 HELPFUL SUGGESTIONS
6.1 Prior to Installation
Before installing the Switch and connecting network devices, it is important to plan the
network's layout. Things you should consider include:
• Dedicated Bandwidth: File servers and other high-traffic hardware improve their
performance if they have their own dedicated 10Mbps,100Mbps, or 1000Mbps bandwidth.
• Full-Duplex: Determine which devices support Full-Duplex connections.
• Fast Ethernet & Gigabit Ethernet: Make sure rules for cable lengths and categories are
followed. 100BASE-TX and 1000BASE-T have the same rules for cable and distance.
• Auto-Negotiation: Devices with different speeds may be easily swapped when the other
end of the cable is fixed to a port with Auto-Negotiation.
6.2 Fast Ethernet & Gigabit Ethernet
1000BASE-T is called "Gigabit Ethernet". In Gigabit Ethernet, data travels ten times faster
(1000Mbps) than in Fast Ethernet (100Mbps).
100BASE-TX is called "Fast Ethernet". In Fast Ethernet, data travels ten times faster (100Mbps)
than in traditional Ethernet (10Mbps).
Note: If your 10BASE-T network currently uses Category 5 TP cabling, you can instantly
upgrade the network to a 100BASE-TX network by changing network devices.
Note: Both 100BASE-TX and 1000BASE-T use Category 5 TP cabling. But 1000BASE-T must
use four pairs twist pair wire. You should check that the Category 5 TP cabling you are using
has four pairs wire before you connect to a Gigabit device. The standard Category 5 TP cabling
pin-out as the following figures:
6.3 MAC Address Table
Every Ethernet data packet includes both source and destination addresses. This six (6) bytes
ID is called the MAC (Media Access Control) Address.
The Switch can automatically learn and store MAC addresses. However, the MAC address
19

table is volatile: it disappears when the Switch is powered “OFF” or reset.
Note: When the network needs reconfiguration, we recommend turning off the power first. After
all nodes have been moved, turn the Switch back "ON" to rebuild the internal MAC address
table.
