1. Introduction
1.1. Product Overview
This user’s manual describes and illustrates the installation method and usage
of the 24-port Fast Ethernet Switch. The rack-mount switch (SS0224/
SE0224) introduced here provides twenty-four 10/100Mbps Fast Ethernet
ports to segment traffic, extend Fast Ethernet connection distance, and
convert data packets between different transmission speeds. This Fast
Ethernet Switch provides shielded RJ-45 ports both with 10Base-T and
100Base-TX Auto-negotiation capability and MDI/MDI-X auto crossover. All
ports in this switch support Full-Duplex and Half-Duplex operation modes.
Addressing the demand for fiber, the switch (SS0224/SE0224) provides two
optional multi-mode or single-mode fiber module supporting SC, ST, MT-RJ,
or VF-45 connector. Hence, the switch can provide maximum 26 ports
simultaneously, i.e. 24 10/100Base-T/TX ports plus two 100Base-FX fast
fiber ports.
Furthermore, this powerful Fast Ethernet Switch utilizes stored-and-forward
switching architecture that filters and forwards data after the complete data
packet is received and examined to be free of errors. With one set of status
LEDs for each individual port, the switch operation status can be easily
monitored. The switch is rack-mount design that can be mounted on the
industrial standard 19 inches rack in the enterprise wiring center.
For SS0224 only, the switch offers advanced software configurable features,
including individual port setting, port-based Virtual Local Area Networking
(VLAN), port-based trunking, 802.1p based QoS, and port mirroring.

2. Installation
2.1. Operating Environment
This switch must be installed and operated within the limits of specified
operating temperature and humidity (see previous section under
Specifications).
• Do not place objects on top of the unit.
• Do not obstruct any vents at the sides of the unit.
• Do not position the unit near any heating source such as heater, radiator,
or direct exposure to sun.
• Prevent entering of water and moisture into the unit.
• If necessary, use dehumidifier to reduce humidity.
• Always avoid dust and dirt.
• Allow some space between the product and the surroundings to facilitate
dissipation of heat generated inside the switch.
2.2. Connecting to network devices
The RJ-45 ports on the switch are designed as MDI/MDI-X auto crossover
ports which allow using straight-through cables to connect any port on this
switch to network device.
Connect one end of the network cable to the RJ-45 port on the front panel,
and connect the other end of the network cable to the RJ-45 port on the
network device. Follow the same procedure to connect all the RJ-45 ports of
the switch. The UTP network cables must comply with EIA/TIA 568
specifications and Category 5 standard for 100Mbps data transmission and
Category 3, 4, 5 for 10Mbps connection. Maximum length, using UTP cable,
between the switch and connected device is 100 meters (328ft). Once the
network cable is connected to both ends and the attached network device is
powered on, the green LINK/ACT LED for corresponding port should be lit
and the other two diagnostic LEDs shall reveal the port is under what kind of
connection status, e.g. full/half duplex, 10/100M speed.

2.3. Connecting the power
Connect the output end of the power cord to the power connector on the
rear panel of the unit. Then connect the power cord to the power outlet.
The green Power LED on the front panel should be lit.
2.4. Fiber Module Installation (Optional)
The fiber module is not included in the package, it’s optional. You can
choose to purchase the fiber module for your switch. The fiber module shall
be inserted into the expansion slot located at the rear of the switch.
• Remove the module from the static free container
• Set Full Duplex or Half Duplex operation mode by using J2 jumper

• Unscrew the cover plate of the expansion slot.
• Remove the plate and keep it for future use when you decide to remove
the module
• With the power off, slide the module into the slot
• Once it is slid in fully, snap in the module to make a proper connection and
fasten the screws
• Then connect the module to the fiber optical cable
• Turn on the power
Once the power is on, the yellow F1(or F2) card exist LED on the front
panel should be lit. Besides, once the fiber is appropriately connected
between fiber module and other network device, the link status shall be seen
by the lit state of the green LED: LINK/ACT for 100FX port.

3. Configuration (SS0224 only)
This section explains the configuration of smart switch, SS0224. For each 10/
100Base- T/TX port, basic setting include port speed, duplex mode, flow
control, auto-negotiation, etc. Other enhanced features configuration
include port-based VLAN, port-based trunking, QoS, and port mirroring.
3.1. Setting up Console Port Connection
To configure your switch through the console port, it is necessary to first set
up a terminal emulation program, and the HyperTerminal for Windows
95,98,and NT is suggested. Before setting the Hyper Terminal, make sure
that the switch, RS-232 cable and the PC are in proper installation. Then
connect PC to the console port in the back of SS0224 using a RS-232 straight
cable.
To configure the Hyper Terminal utility, please go with the following steps:
• Running the Hyper Terminal utility program.
• Select COM port to communicate with SS0224.
• Set the serial port properties then Press OK.
