Preface
Benefits of Switching
Ethernet switching technology has dramatically boosted the total
bandwidth of a network. It puts configuration flexibility and bandwidth
adaptability into the local workgroups where the majority of work is
generated.
It further eliminates congestion problems inherent to the CSMA/CD
protocol and improves predictable response time under heavy network
loads. In the past, expensive routing equipment was used to reduce the
congestion under heavy loads. Now, high per formance switch gear is
affordable and available in the compact, desktop units.

Hardware Description
This Section describes the hardware of the Pro-Switch/8F and gives a
physical and functional overview of its features.
The Front Panel
The front panel consists of (8) fiber ports, DIP switches, and LED
Indicators.
Figure 1. Front Panel view of Pro-Switch/8F
Ports
The 100Base-FX ports are capable of accepting 100Base-FX
connections only.
When connected to a 100Base-FX network, the ports operate at
100Mbps in half-duplex mode and 200Mbps in full-duplex mode.
The maximum range of an FX fiber link between a switch and another
device is up to 2 Km. using Multi-mode, 62.5/125µ fiber-optic cable or
up to 75 Kilometers using Single, 10/125-µ fiber optic cable.
The following table summarizes the port and cable specifications for
this switch.

Network Application
This section provides a few samples of network topology in which the
Switch is used. The Pro-Switch/8F is designed to be used as a backbone
switch. With its large address table (4000 MAC address), Fiber por ts, and
high performance, it is ideal for connecting WANS to LAN network
segments.
You can use the Pro-Switch/8F to connect multiple floors of a building or
even multiple buildings via the fiber optic ports. The switch automatically
learns node addresses, which are subsequently used to filter and forward
all traffic based on the destination address. The distance between two
switches via fiber cable can be up to 2 km (Multi-Mode) or 15 km (Single
Mode).
Segment Bridge
For enterprise networks where large data broadcasts are constantly
processed, this switch is an ideal backbone solution.

DIP-Switch Setup
The DIP-switch is used to configure full- or Half-duplex switching. The DIP-
switch setup is as follows:
Position Description
UP: Enables Full-Duplex Operation for 100Based-FX ports (default)
DOWN: Enables Half-Duplex Operation for 100Based-FX ports

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 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.

Rackmount Installation
Included with the Pro-Switch/8F are brackets allowing the switch to be
mounted in a standard EIA-sized, 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. Align one bracket with the holes on one side of the switch and secure
it with the small bracket screws. Then attach the remaining bracket to
the other side of the Switch.
B. After attaching both mounting brackets, position the Pro-Switch/8F 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 larger rack-mounting screws.
Note: For proper ventilation, allow at least 4” ( 10 cm ) of clearance at the front
and 3.4” ( 8 cm ) at the back of the Switch. This is especially important for
an enclosed rack installation.

Connecting to Power
Connect the supplied AC power cord to the receptacle on the back of the switch,
and then plug the cord into a standard AC outlet with a voltage range from 100
to 250 VAC.
Turn the switch on by flipping the ON/OFF switch on the rear of the unit to the I
(ON) position. The O position is OFF.

General Installation
This chapter presents step-by-step installation instructions for this eight-
port Ethernet Switch.
Selecting a Site for the Switch
As with any electronic device, you should place the Switch where it will not
be subjected to extreme temperatures, humidity, or electromagnetic
interference. Specifically, the site you select should meet the following
requirements:
• The room temperature should be between 32 and 104 degrees
Fahrenheit (0˚- 40˚ Celsius).
• The relative humidity should be less than 90%, non-condensing.
• Surrounding electrical devices should not exceed the electromagnetic
field (RFC) standards for IEC 801-3, Level 2 (3V/M) field strength.
• Make sure that the switch receives adequate ventilation. Do not block
the ventilation holes on the side of the switch or the fan exhaust port
on the rear of the switch.
• The power outlet should be within 1.8 meter (6 feet) of the switch.
