1. Introduction 

 
GSW-2453, 3-slot Gigabit Chassis switch, is a modular Switch that can be used to 

build high-performance switched workgroup networks. This switch is a 

store-and-forward device that offers low latency for high-speed networking. The Switch 

is targeted at workgroup, department or backbone computing environment. 

 

GSW-2453 features a “store-and-forward “ switching scheme. This allows the switch to 

auto-learn and store source address in an 4K-entry MAC address table. 

 

MDI

 (Medium Dependent Interface) Port is also called an "uplink port". The MDI port 

does not cross transmit and receive lines, which is done by the regular ports (MDI-X 

ports) that connect to end stations. In general, MDI means connecting to another Hub 

or Switch while MDIX means connecting to a workstation or PC. Therefore, Auto

 

MDI/MDIX means that you can connect to another Switch or workstation without 

changing non-crossover or crossover cabling. 

 

GSW-2453 has 3-module slot. User can accord their needs to purchase the modules. 

This can give elasticity on network application.

Ethernet Switching Technology                                     

 

Ethernet Switching Technology dramatically boosted the total bandwidth of a network, 

eliminated congestion problems inherent with CSMA/CD (Carrier Sense multiple 

access with Collision Detection) protocol, and greatly reduced unnecessary

transmissions. 

 

This revolutionized networking. First, by allowing two-way, simultaneous transmissions 

over the same port (Full-duplex), which essentially doubled the bandwidth. Second, by 

reducing the collision domain to a single switch-port, which eliminated the need for 

carrier sensing. Third, by using the store-and-forward technology’s approach of 

inspecting each packet to intercept corrupt or redundant data, switching eliminated 

unnecessary transmission that slow the network. By employing address learning, 

which replaced the inefficient receiving port. 

 

Auto-negotiation regulates the speed and duplex of each port, based on the capability 

of both devices. Flow-control allows transmission from a 1000Mbps node to a 

100Mbps node without loss of data. Auto-negotiation and flow-control may require 

disablement for some networking operations involves legacy equipment. Disabling the 

auto-negotiation is accomplished by fixing the speed or duplex of a port.   

 

Ethernet Switching Technology supplied higher performance at costs lower than other 

solutions. Wider bandwidth, no congestion, and the reduction in traffic is why switching 

is replacing expensive routers and inefficient hubs as the ultimate networking solution. 

Switching brought a whole new way of thinking to networking.

Rear Panel                                       

 

The 3-pronged power plug, 2 fans, power switching is located at the rear panel of the 

GSW-2453 as shown in Figure 2-2. The switch will work with AC power in the range of 

100-240V AC, 50-60Hz. 

 

 

Figure 2-2. The Rear Panel

Desktop Installation                                

 

 

Set the Switch on a sufficiently large flat space with a power outlet nearby. The surface 

where you put your Switch should be clean, smooth, level and sturdy. Make sure there 

is enough clearance around the Switch to allow attachment of cables, power cord and 

allow air circulation. 

 

Attaching Rubber Feet

 

 

A.  Make sure mounting surface on the bottom of the Switch is grease and dust free.   

B.  Remove adhesive backing from your Rubber Feet.   

C.  Apply the Rubber Feet to each corner on the bottom of the Switch. These footpads 

can prevent the Switch from shock/vibration. 

 

 

Rack-mounted Installation                                   

 

 

The switch come with a rack-mounted kit and can be mounted in an EIA standard size, 

19-inch Rack. The Switch can be placed in a wiring closet with other equipment. 

 

Perform the following steps to rack mount the switch:

A.  Position one bracket to align with the holes on one side of the switch and secure it 

with the smaller bracket screws. Then attach the remaining bracket to the other 

side of the Switch. 

B.  After attached both mounting brackets, position the switch in the rack by lining up 

the holes in the brackets with the appropriate holes on the rack. Secure the Switch 

to the rack with a screwdriver and the rack-mounting screws. 

Note:

 For proper ventilation, allow about at least 4 inches (10 cm) of clearance on 

the front and 3.4 inches (8 cm) on the back of the Switch. This is especially 

important for enclosed rack installation. 

 

 

Power On                                   

 

Connect the power cord to the power socket on the rear panel of the Switch. The other 

side of power cord connects to the power outlet. The internal power supply of the 

Switch works with voltage range of AC power in the 100-240VAC, frequency 50~60Hz. 

Check the power indicator on the front panel to see if power is properly supplied.

3. Network Application 

 

 

GSW-2453 is designed as a segment switch. That is, with its large address table (4000 

MAC address) and high performance, it is ideal for interconnecting networking 

segments. 

 

PC, workstations, and servers can communicate each other by directly connecting with 

3-slot Gigabit Chassis s switch. The switch automatically learns nodes address, which 

are subsequently used to filter and forward all traffic based on the destination address. 


By using Gigabit or Gigabit Fiber the switch can connect with another switch or hub to 

interconnect other small-switched workgroups to form a larger switched network. 

Meanwhile, you can also use Ethernet or Gigabit fiber ports to connect switches.

4. Troubleshooting 

 

 

This section is intended to help you solve the most common problems on the 

GSW-2453. 

 

Incorrect connections                                

 

The switch port can auto detect straight or crossover cable when you link switch with 

other Ethernet device. For the UTP connector should use correct UTP or STP cable, 

10/100Mbps port use 2 pairs twisted cable and Gigabit 1000T port use 4 pairs twisted 

cable. If the UTP connector is not correct pin on right position then the link will fail.   

For fiber connection, please notice that fiber cable mode and fiber module should be 

match.

 

 

„

 

Faulty or loose cables 

 

Look for loose or obviously faulty connections. If they appear to be OK, make sure the 

connections are snug. IF that does not correct the problem, try a different cable. 

 

„

 

Non-standard cables 

 

Non-standard and miss-wired cables may cause numerous network collisions and 

other network problem, and can seriously impair network performance. A category 

5-cable tester is a recommended tool for every 100Base-T network installation. 

 

„

 

Improper Network Topologies 

 

It is important to make sure that you have a valid network topology. Common topology 

faults include excessive cable length and too many repeaters (hubs) between end 

nodes. In addition, you should make sure that your network topology contains no data 

path loops. Between any two ends nodes, there should be only one active cabling path

at any time. Data path loops will cause broadcast storms that will severely impact your 

network performance. 

 

 

Diagnosing LED Indicators                   

 

The Switch can be easily monitored through panel indicators to assist in identifying 

problems, which describes common problems you may encounter and where you can 

find possible solutions. 

 

IF the power indicator does turn on when the power cord is plugged in, you may have a 

problem with power outlet, or power cord. However, if the Switch powers off after 

running for a while check for loose power connections, power losses or surges at 

power outlet. IF you still cannot resolve the problem, contact your local dealer for 

assistance. 

 

 

 

Cabling                                   

 

UTP ports

 

use unshielded twisted-pair (UTP) or shield twisted-pair ( STP ) cable for 

RJ-45 connections: 100

Ω

  Category 3, 4 or 5 cable for 10Mbps connections or 100

Ω

 

Category 5 cable for 100Mbps connections. Also be sure that the length of any 

twisted-pair connection does not exceed 100 meters (328 feet). Gigabit port should 

use Cat-5 or cat-5e cable for 1000Mbps connections. The length does not exceed 100 

meters.
