2.3.1 1000BASE-T
The switch is primarily used for network backbone connections.
For the 1000BASE-T TP port, it provides an Auto-Negotiation function that senses 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 Auto-Negotiation function will
do the rest.
2.3.2 Cabling
1000Mbps - To transmit at 1000Mbps requires Category 5 TP cabling that must use all Four (4)
pairs twisted-pair wire for RJ-45 connector.
100Mbps - To transmit at 100Mbps requires Category 5 TP cabling.
10Mbps - When transmitting at 10Mbps Category 3, 4 or 5 TP cabling with RJ-45 sockets can be

HELPFUL SUGGESTIONS
4.1
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.
4.2
Half- and Full-Duplex
The Switch supports both Half- and Full-Duplex modes for 10BASE-T and 100BASE-TX. But the
1000BASE-T only supports Full-Duplex mode.
In Half-Duplex mode: Data cannot be transmitted and received at the same time. Attached
devices must finish transmitting data before they can receive data.
In Full-Duplex mode: Data can be transmitted and received at the same time.
However:
Full-Duplex transmission is only possible between two devices with a dedicated link (e.g.,
Switch-Switch, Switch-PC)
Both devices must have Full-Duplex capability
Both devices must be set to Full-Duplex (e.g. Auto-Negotiation – Auto-Negotiation,
Non-Auto-Negotiation to Non-Auto-Negotiation)
The 100BASE-TX/10BASE-T or 1000BASE-T/100BASE-TX/10BASE-T ports on the Switch detect
and set the line's operating mode by using their Auto-Negotiation function.
4.3
Auto-Negotiation
Every 10/100/1000Mbps speed port on these Switches has a built-in "Auto-Negotiation" function.
This technology automatically sets the best possible bandwidth as soon as a connection is
established with another network device (usually at Power “On” or Reset). This is capability is
achieved via the Switch’s Auto-Negotiation function that automatically detects the modes and
speeds the second (attached) device is capable of.
Evaluating Auto-Negotiation Capability:
if attached device is: the Switch will automatically set its TP ports to operate at:
1000Mbps
2000Mbps (1000BASE-T, Full-Duplex)
with Auto-Negotiation Note: Almost all 1000Mbps devices only operate in Full-Duplex mode.
100Mbps
100Mbps (100BASE-TX, Half-Duplex)
200Mbps (100BASE-TX, Full-Duplex)
10Mbps (10BASE-T, Half-Duplex)
20Mbps (10BASE-T, Full-Duplex)
no Auto-Negotiation
100Mbps
with Auto-Negotiation
10Mbps
no Auto-Negotiation
10Mbps
with Auto-Negotiation
Note: If the attached device is set to a fixed mode (ex: Forced Full-Duplex) it will not operate as an
Auto-Negotiation device.
4.4
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.
9
Download from Www.Somanuals.com. All Manuals Search And Download.
The models can automatically learn and store MAC addresses. However, the MAC address table is
volatile: it disappears when the Switch is powered “Off” or reset.
Note: When the network needs reconfiguration, we recommend to restart the Switch first. After all
nodes have been moved, Remove the power cord and re-attach it to rebuild the internal MAC
address table.

SMART FUNCTION CONFIGURATION
6.1
HyperTerminal
The Switch has a smart function that you can use to manage your local area network (LAN) more
effectively. You can also use the default setting to operate the Switch 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:

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 9600, “Data bits” to 8, “Parity” to
None, “Stop bits” to 1, “Flow control” to None.

Mirror Config
Port Mirroring means setting up a monitored port so that data flowing through that port is copied to
the snooping port. The port used to monitor other port is called the Snooping port. The port being
watched is called the Mirrored Port. The Switch is able to monitor one port at one time. The
transmitting and receiving direction can be monitored exclusively. Be sure to activate this function
before setting port selection and direction.
