RADIO FREQUENCY INTERFERENCE STATEMENT
Class B Digital Device. This equipment has been tested and found to comply with the limits for a
Class B computing device pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. However, there is no
guarantee that interference will not occur in a particular installation. This equipment generates, uses,
and can radiate radio frequency energy, and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. If this equipment does cause
harmful interference to radio or telephone reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
• Consult an experienced radio/TV technician for help.
Caution:
Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
To meet FCC requirements, shielded cables and power cords are required to connect this device to a
personal computer or other Class B certified device.

Packing List
When you unpack the switch, you should find the items listed below. Please
inspect the contents, and report any apparent damage or missing items
immediately to your authorized reseller.
• The two-port Ethernet switch
• User's Manual
• AC power cord
Front Panel
The front panel of this switch has two ports and an array of LED indicators to
provide you with instant feedback on the switch
status.
Figure 1: Front panel of the 10/100TX and 100FX Switch
Ports
The TX port of this switch is capable of accepting either a 10BASE-T or a
100BASE-TX network. It automatically senses and adapts itself to the
presence of either network standard. The fiber port on the Ethernet switch is
capable of accepting 100Base-FX connections only.
Cable Length
The maximum distance between a node and a directly connected switch port
on a 100BASE-TX network is 100 meters with Category 5 shielded twistedpair (STP) cable or unshielded twisted-pair (UTP) cable. On a 10BASE-T
network, it may range up to 100 meters with Category 3, 4, or 5 STP/UTP
cable.
As for the length of fiber connection between a switch and a Data Terminal
Equipment, it is capable of spanning at most 2 kilometers (1.24 miles) using
62.5/125 µm multi-mode fiber-optic cable or up to 75 kilometers using
10/125 µm single-mode fiber optic cable.

n Port Status
There are two LED ( LNK/ACT, FDX/COL ) for 100Base-FX port and three
LED ( LNK/ACT, FDX/COL, SPEED ) for 10/100Base-TX port to show
status information. The LEDs are identified by a corresponding array of
captions located above and below the LEDs on the front panel.
LNK/ACT:
There are two LNK/ACT LEDs on the front panel:
The LED next to TX port indicates status on TX port, and the one next to
FX port indicates status on FX port.
When the LED is illuminating whenever the port is connected to another
working networked device and flashing when the port is transmitting or
receiving data.
FDX/COL:
There are two FDX/COL LEDs on the front panel:
The LED next to TX port indicates status on TX port, and the one next to
FX port indicates status on FX port.
The LED is illuminating when the port is operating in full-duplex mode. The
LED is off when the port is operating in half-duplex mode.
The LED is flashing when the switch detects packet collisions on the port.
Express Ethernet Switch
100:
The low-right LED is illuminating whenever the switch detects the TX port
is connected to a 100BASE-TX segment. The LED is off when the TX port
is connected to a 10BASE-T segment.

o Power
This LED will be on when the switch is connected to a power supply and turned on.
Rear Panel
The power cord receptacle and on/off switch is located on the rear panel of
the switch.

Installation
Express Ethernet Switch
This chapter presents step-by-step installation instructions for the two-port
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 to 40 degrees Celsius).
• The relative humidity should be less than 90 percent, 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 at the
rear of the switch.
• The power outlet should be within 1.8 Meters of the switch.
Detailed specifications may be found on page 11.
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 AC.
10
Express Ethernet Switch
Turn the Ethernet switch on by flipping the ON/OFF switch on the rear of
the unit to the I (ON) position. The O position is OFF.
Connecting to Your Network
Connect cables to computers or network segments into the RJ-45 ports on
the front of this switch. The non-fiber ports support 10BASE-T or
100BASE-TX with full or half duplex. The fiber port on the switch supports
100BASE-FX with full or half duplex.
The cable for RJ-45 ports must be a Category 5 unshielded twisted-pair (
UTP) cable for 100BASE-TX, or Category 3, 4, or 5 UTP cable for
10BASE-T. The cable for fiber port must be a 62.5/125 micron fiber-optic
cable for 100BASE-FX.
