1. Introduction
The KFS-2621 is a managed Fast Ethernet switch which is featured with the following switched ports and
advantages in a 19” rack mountable box:
24 10/100Mbps Fast Ethernet copper ports
2 combo ports - 10/100/1000Mbps copper & 1000Base-X SFP
Model Definition
Model Description Management Power Input
KFS-2621-S AC power model Managed AC 100 ~ 240V
KFS-2621-D DC power model Managed DC 36 ~ 72V
Plug and Play
The switch is shipped with factory default configuration which behaves like an unmanaged Fast Ethernet
switch for workgroup. It provides 24 10/100Mbps copper ports for connections to Ethernet and Fast Ethernet
devices. With the featured auto-negotiation function, the switch can detect and configure the connection speed
and duplex automatically. The switch also provides auto MDI/MDI-X function, which can detect the connected
cable and switch the transmission wire pair and receiving pair automatically. This auto-crossover function can
simplify the type of network cables used.
Gigabit Ethernet Connectivity
Two Gigabit combo ports are provided in the switch. The combo port provides one 10/100/1000Mbps RJ-45
for connecting to Gigabit copper device and one 1000M SFP slot, which can be installed with optional SFP
optical fiber transceivers to support one Gigabit 1000Base-X fiber connections respectively when needed.
Fiber Connectivity
The 1000M SFP slot provided in a combo port, which can be installed with optional SFP optical fiber
transceivers to support one Gigabit 1000Base-X fiber connection when needed.
Management
The switch is embedded with an Http server which provides management functions for advanced network
functions including Port Control, Quality of Service, and Virtual LAN functions. The management can be
performed via Web browser based interface over TCP/IP network.
Quality of Service

-7-
For advanced application, the switch is featured with powerful Quality of Service (QoS) function which can
classify the priority for received network frames based on the ingress port and frame contents. Furthermore,
many service priority policies can be configured for egress operation in per-port basis.
Virtual LAN (VLAN)
For increasing Tagged VLAN applications, the switch is also featured with powerful VLAN function to fulfill
the up-to-date VLAN requirements. The switch supports both port-based VLAN and tagged VLAN in per-port
basis.

2.6 Reset Button
The reset button is used to perform a reset to the switch. It is not used in normal cases and can be used for
diagnostic purpose. If any network hanging problem is suspected, it is useful to push the button to reset the
switch without turning off the power. Check whether the network is recovered.
The button can also be used to restore the software configuration settings to factory default values. The
operations are:

3. Making Connections and Configuring IP Address
3.1 Making UTP Connections
The 10/100 and 10/100/1000 RJ-45 copper ports support the following connection types and distances:
Network Cables
10BASE-T: 2-pair UTP Cat. 3, 4, 5, EIA/TIA-568B 100-ohm
100BASE-TX: 2-pair UTP Cat. 5, EIA/TIA-568B 100-ohm
1000BASE-T: 4-pair UTP Cat. 5 or higher (Cat.5e is recommended), EIA/TIA-568B 100-ohm
Link distance: Up to 100 meters
Auto MDI/MDI-X Function
This function allows the port to auto-detect the twisted-pair signals and adapts itself to form a valid MDI to
MDI-X connection with the remote connected device automatically. No matter a straight through cable or
crossover cable are connected, the ports can sense the receiving pair automatically and configure themselves to
match the rule for MDI to MDI-X connection. It simplifies the cable installation.
Auto-negotiation Function
The ports are featured with auto-negotiation function and full capability to support connection to any Ethernet
devices. The port performs a negotiation process for the speed and duplex configuration with the connected
device automatically when each time a link is being established. If the connected device is also
auto-negotiation capable, both devices will come out the best configuration after negotiation process. If the
connected device is incapable in auto-negotiation, the switch will sense the speed and use half duplex for the
connection.
Port Configuration Management
For making proper connection to an auto-negotiation INCAPABLE device, it is suggested to use port control
function via software management to set forced mode and specify speed and duplex mode which match the
configuration used by the connected device.

-19-
3.2 Making Fiber Connection
The SFP slot must be installed with an SFP fiber transceiver for making fiber connection. Your switch may
come with some SFP transceivers pre-installed when it is shipped.
Installing SFP Fiber Transceiver
To install an SFP fiber transceiver into SFP slot, the steps are:
1. Turn off the power to the switch.
2. Insert the SFP fiber transceiver into the SFP slot. Normally, a bail is provided for every SFP transceiver.
Hold the bail and make insertion.
3. Until the SFP transceiver is seated securely in the slot, place the bail in lock position.

-20-
Connecting Fiber Cables
LC connectors are commonly equipped on most SFP transceiver modules. Identify TX and RX connector
before making cable connection. The following figure illustrates a connection example between two fiber
ports:
Make sure the Rx-to-Tx connection rule is followed on the both ends of the fiber cable.
Network Cables
Multimode (MMF) - 50/125Pm, 62.5/125Pm
Single mode (SMF) - 9/125Pm
Fiber Port Configuration
For 1000M fiber application on Port 25 and Port 26, just leave the default port configuration Auto for fiber
connection.
