2. Introduction To 10/100/1000Mbps Gigabit Switch

2.1 General Description

The device is a powerful, high-performance 1 0/100/1000Mbps Fast Ethernet and
Gigabit switch, with all 8 ports capable of 10/100/1000Mbps auto-negotiation
operation (NWay), which means the switch could automatically ne gotiate with the
connected partners on the network speed and duplex mode. Moreover, the
10/100/1000Mbps auto-sensing ability provides an easy way to migrate 10Mbps to
100Mbps or 1000Mbps networks with no pain. Co mpared to the shared 10Mbps,
100Mbps or 1000Mbps networks, the switch delivers a dedicated 10/100/1000Mbps
connection to every attached client with no bandwidth congestion issue.

All Gigabit ports support auto-negotiation operation, auto MDI-X crossover function
and Full-Duplex mode. They are ideal for micro-segmenting large networks into
smaller, connected subnets for improved performance, enabling the bandwidth
demanding multimedia and imaging applications. The device also provides the fat
pipe to the servers or backbone connection for boosting the total system
performance.

The built-in smart capabilities, VLAN, Port-Trunking, Port Config, Port Priority, Port
snooping and 4-level IP priority, empowered system administrator to monitor and
control the network easily.

Store-and-forward switching mode promises the low latency plus eliminates all the
network errors, including runt and CRC error packets. To work under full-duplex
mode, transmission and reception of the frames can occur simultaneously without
causing collisions as well as double the network bandwidth.

The switch is plug-n-play without any software to configure and also fully compliant
with all kinds of network protocols. Moreover, the rich diagnostic LEDs on the
front-panel can provide the operating status of individual port and whole system.

For network connection:

The switch can use the following types of cabling:

 10BASE-T: Category 3, 4 or 5 UTP/STP
 100BASE-TX: Category 5 UTP/STP
 1000BASE-T: Category 5 UTP/STP

Category 5 cable is preferred to use with this product in structured wiring
environments. This will ensure correct operation of all ports at 10Mbps,
100Mbps or 1000Mbps.

2.3.1 System LEDs

System LED indicators are located on the front panel for showing the operating
status of the whole device.

2.3.1.1 Power LED

This indicator lights green when the switch is receiving power;
otherwise, it is off.

2.3.1.2 Trunk A/B LED

The switch supports 2 groups port-trunk; port-1 and port-2 belong to
“Trunk A”, port-7 and port-8 belong to “Trunk B”. This indicator lights
green when the relative group is functioning.
