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.

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.]

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.
