1. Introduction
Gigabit Et ernet over copper tec nology is a proven cost-effective way for
network equipment to be upgraded from Fast Et ernet to Gigabit speeds.
Standard 4-pair Category 5e/6 copper cabling eliminates t e need for
expensive fiber optic cabling for Gigabit speeds. T is tec nology creates
ig -speed backbone connections between switc es, servers, databases,
and workstations.
T e DynaGST/2402G Gigabit Et ernet switc is an ideal solution for solving
traffic congestion at t e core of t e network. It offers auto-negotiation
10/100/1000Base-T Gigabit Et ernet ports t at can significantly improve
your network backbone performance. It will also fit into any enterprise level
network as an exit to t e backbone switc . T e DynaGST/2402G provides
two mini GBIC Gigabit slots for Gigabit speed network connection.
T e DynaGST/2402G Gigabit Et ernet switc features Auto MDI/MDIX
function for eac port and features a store-and-forward switc ing. It auto-
learns and stores source address on an 8K MAC address table.

2. Hardware Description
T is Section describes t e ardware of t e DynaGST/2402G Gigabit
Et ernet switc .
T e p ysical dimensions of t e DynaGST/2402G Gigabit Et ernet switc is:
440 x 161 x 44 mm (W x D x H)
Front Panel
T e Front Panel of t e DynaGST/2402G Gigabit Et ernet switc consists of
twenty four (24) auto-negotiation 10/100/1000Mbps Et ernet RJ-45
connectors (wit Automatic MDI/MDIX support), two Mini GBIC slots, and
LED indicators (1000, Link/Activity, Full duplex/Collision) for eac Gigabit
port and power for t e unit.
Figure 2-1. T e Front Panel of t e DynaGST/2402G Gigabit Et ernet switc
 RJ-45 Ports (Auto MDI/MDIX): Twenty-four (24) auto-negotiation
10/100/1000 Mbps Et ernet RJ-45 connectors
 Mini GBIC ports: Ports 23 and 24 auto-detect between t e Gigabit
copper ports and t e Mini GBIC (Gigabit fiber) ports. T ey support 3.3V
Mini SFP GBIC modules. T ese modules are optional. T ere are two
LED indicators for t e Mini GBIC ports – LNK and ACT. If a Mini GBIC
module is not installed, ports 23 and 24 operate in Gigabit copper mode
only.
[Note] W en t e Mini GBIC module is installed, t e Mini GBIC (Gigabit
fiber) ports ave ig er priority t an t e Gigabit copper ports and supercede

t em. It doesn’t matter if t e Gigabit copper port is connected before or after
t e Mini GBIC port is connected. T e Mini GBIC port always as ig er
priority for connection. W en t e Mini GBIC port is connected, t e Gigabit
copper ports are disabled.
Rear Panel
T e 3-pronged power plug, on/off switc , and Ventilation fan are located at
t e rear Panel of t e DynaGST/2402G Gigabit Et ernet switc as s own in
Figure 2-2. T e Switc will work wit AC in t e range 100-240V AC, 50-
60Hz.

3. Installation
Set t e Switc on a sufficiently large flat space wit a power outlet nearby.
T e surface s ould be clean, smoot , level, and sturdy. Ensure t ere is
enoug clearance around t e Switc to allow air circulation and t e
attac ment of t e power cord and cables.
Attaching Ru er Feet
 Make sure mounting surface on t e bottom of t e Switc is grease and
dust free.
 Remove ad esive backing from your Rubber Feet.
 Apply t e Rubber Feet to eac corner on t e bottom of t e Switc .
T ese footpads protect t e Switc from s ock and vibration.
Power On
Connect t e power adapter cable to t e power socket on t e rear panel of
t e Switc . T e ot er end of t e power cord connects to t e power outlet.
C eck t e power indicator on t e front panel to make sure if power is
properly supplied.

4. Network Application
T is section provides a sample of network topology in w ic t e
DynaGST/2402G is used. In general, t e DynaGST/2402G Gigabit Et ernet
switc is designed as a ig -bandwidt backbone switc .
You can use t e DynaGST/2402G to connect servers, switc es,
workstations, and PCs to eac ot er by connecting t ese devices directly to
t e Switc . T e Switc automatically learns node addresses, w ic are
subsequently used to filter and forward all traffic based on t e destination
address. T e Gigabit fiber port is designed to connect t e Et ernet network
wit a fiber network.
For enterprise networks w ere large data broadcasts are constantly
processed, t is switc is an ideal link between departmental switc es and
t e core switc . All workstations can connect to departmental switc es and
t ose switc es are t en connected to t e DynaGST/2402G Gigabit Et ernet
switc . Now all t e devices in t is network can communicate wit eac
ot er. Connecting servers to t e core switc is important because it allows
eac workstation to access t e server’s data.
T is switc is a perfect for backbone connectivity.

5. Trou leshooting
T e Switc can be easily monitored t roug panel indicators to assist in
identifying problems. T is section describes common problems you may
encounter and w ere you can find possible solutions.
 Diagnosing LED Indicator
If t e Link indicator does not lig t up after connection, c eck w et er t e
network interface (e.g., a network adapter card on t e attac ed device),
network cable, or switc port is defective. Verify t at t e switc and attac ed
device are powered on. Ensure t e cable is plugged into bot t e switc and
corresponding device. Verify t e proper cable type is used and its lengt
does not exceed specified limits.
 Power
If t e power indicator does turn on w en t e power cord is plugged in, you
may ave a problem wit power outlet or power cord. However, if t e Switc
powers off after running for a w ile c eck for loose power connections, local
power losses, or surges at power outlet. If you still cannot resolve t e
problem, contact your local dealer for assistance.
 Transmission Mode
Eac port will automatically set to t e same transmission mode used by t e
attac ed device (i.e., alf or full duplex). T e RJ-45 ports use auto-
negotiation to set t e transmission mode. If t e attac ed device does not
support auto-negotiation t en t is switc will default to t e lowest common
speed.

12
 Ca ling
RJ-45 ports: Use uns ielded twisted-pair (UTP) or s ield twisted-pair (STP)
cable for RJ-45 connections: 100m. of Category 3,5e, or 6 cable for 10Mbps
connections, 100m. of Category 5e/6 cable for 100Mbps connections , or
100m. of 4-pair Category 5e/6 copper cabling for 1000Mbps connection.
Also be sure t at t e lengt of any twisted-pair connection does not exceed
100 meters (328 feet).
