1. Introduction  
Congratulations on your purchase of FSW-1621/2421.  
The FSW-1621/2421, 16/24-port 10/100Base-TX Switch, is a multi-port  
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 at SME (small, medium  
enterprise) business.  
The 16/24-port 10/100Base-TX Switch features a “store-and-forward  
“switching scheme. This allows the switch to auto-learn and store source  
address on 8K/4K-entry MAC address table.

2. Hardware Description  
This Section mainly describes the hardware of the 16/24-port  
10/100Base-TX Switch, and gives a physical and functional overview of  
this Switch.  
The physical dimensions of the FSW-1621/2421 is:  
250mmx 133 mm x 37mm (L x W x H)  
Front Panel  
FSW-1621/2421 consists of 16/24 x 10/100Base-TX RJ-45 ports. The  
LED Indicators are also located on the front panel of the Switch.  
Figure 2-1. The Front view of FSW-1621/2421  
RJ-45 ports (Auto MDI/MDIX): 16/24x 10/100Mbps auto-sensing port for  
10Base-T or 100Base-TX devices connection.  
[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.]  
 
LED Indicators  
The LED Indicators gives real-time information of systematic operation  
status. The following table provides descriptions of LEDs status and their  
meaning.

Rear Panel  
The 3-pronged power plug is located at the rear panel of the 16/24-port  
10/100Base-TX Switch as show in the Figure 2-3. The Switch will work  
with AC in the range 100-240V AC, 50-60Hz.

Desktop Installation  
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  
FSW-1621/2421 10/100Base-TX Switch comes with a long 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 FSW-1621/2421 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.  
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  
external power supply in the Switch works with AC in the voltage range  
100-240VAC, frequency 50~60Hz.Check the power indicator on the front  
panel to see if power is properly supplied.  
 
3.Network Application  
This section provides you a few samples of network topology in which the  
Switch is used. In general, FSW-1621/2421 is designed as a segment  
switch. That is, with its large address table and high performance, it is  
ideal for interconnecting networking segments.  
You can use the FSW-1621/2421 to connect PCs, workstations, and  
servers to each other by connecting these devices directly to the Switch.  
The switch automatically learns nodes address, which are subsequently  
used to filter and forward all traffic based on the destination address. By  
using Uplink port, the Switch can connect with another switch or hub to  
interconnect each of your small-switched workgroups to form a larger  
switched network.  
Small Workgroup  
The 16/24-port 10/100Base-TX Switch can be used as a standalone  
switch to which personal computers, server, printer server, are directly  
connect to form small workgroup.

Segment Bridge  
For enterprise networks where large data broadcasts are constantly  
processed, this switch is an ideal solution for department users to connect  
to the corporate backbone.  
In the illustration below, two Ethernet switches with PCs, print server, and  
local server attached, are both connect to the FSW-1621/2421. All those  
devices in this network can communicate with each other through  
FSW-1621/2421 Switch. Connecting servers to the Switch allow other  
users to access the server’s data.
