1 Getting to know the Switch
1.1 Introduction
The Gigabit Ethernet Switch is equipped with 16 Gigabit copper ports and each port
provides a max speed of 2000Mbps and a Full-Duplex, Collision Free Bandwidth. It’s a
multi-speed, versatile network device that combines Gigabit, Fast Ethernet, and
Ethernet ports in a single device. This device meets RoHS compliance. It is
power-saving with Green Ethernet technology.
1.2 Key Features
．Supports Auto-Negotiation on each TP port
．Supports 9216byte maximum packet length
．Supports Green Ethernet
．Link-On and Cable Length Power Saving
．Link-Down Power Saving
．IEEE 802.3az Energy Efficient Ethernet (EEE) supported
．Provides Store-and-Forward switching scheme
．Supports Auto-MDI/MDI-X function
．Supports IEEE 802.3x Flow-Control for Full-Duplex operation
．Back-Pressure function supports for Half-Duplex operation
．Non-Blocking Performance Improves Access to Network Resources
．8K-entry lookup MAC address table
1.3 The Front Panel
1.3.1 Network Ports
The Switch is equipped with eight RJ-45 ports that support network speeds of
10/100/1000Mbps.
1.3.2 Cabling
1000Mbps - To transmit at 1000Mbps requires Cat.5 TP cabling that has all Four (4)
twisted-pair wires connected in RJ45 connector.
100Mbps - To transmit at 100Mbps requires Cat. 5 cabling.
10Mbps - When transmitting at 10Mbps, Cat. 3, 4 or 5 TP cabling with RJ-45 sockets
can be used.

2 Useful Tips
2.1 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 will have better
and improved 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.
2.2 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 10/100/1000Mbps ports on the switch detect and set the line's operating mode by
using their Auto-Negotiation function.
2.3 Auto-Negotiation
Every 10/100/1000Mbps port on the switch has a built-in "Auto-Negotiation" function.
This technology allows each port to automatically sense and set the best possible
speed as soon as a connection with another network device is established (usually at
Power “On” or Reset).
Evaluating Auto-Negotiation Capability:
if attached device is: The switch will automatically set its TP ports to operate at:
1000Mbps
with Auto-Negotiation
2000Mbps (1000BASE-T, Full-Duplex)
Note: Almost all 1000Mbps devices only operate in
Full-Duplex mode.
