environment where traffic on the network and the numbers of users increase
continuously; it can be installed where space is limited, and it provides
immediate access to a rapidly growing network through a wide range of userreliable functions and features, as described in the following section.

Product Description
Key Features
The AT-FS704 unmanaged Fast Ethernet switch has the following features:
2
❑
IEEE 802.3 and 802.3u compliant.
❑
Store-and-forward at full wire speed to support rate adaptation and
ensure data integrity.
❑
Auto-negotiation for any port. This allows for auto-detection of speed
(10/100 Mbps) and duplex mode (full- or half-duplex), thereby
providing automatic and flexible solutions in your network
connections.
❑
Auto polarity detection for correction of incorrect polarity on the
receive twisted pair at each port.
❑
Data packet forwarding and filtering at full wire speed.
❑
8 K active MAC address entry table per device with self learning and
table aging.
❑
4 MB packet buffer per device.
❑
Uplink/MDI (Media-Dependent Interface) port for uplink to another
switch, hub or repeater. Please note that if you are using the uplink
port, you will be unable to use Port 1, as these two ports are logically
connected.

Product Description
LED Indicators
The LED indicators include POWER, 100 M, LINK/ACT (Link/Activity) and
FULL DUP/COLN (Full-duplex/Collision). The LED indicators are used to
facilitate monitoring and troubleshooting of the switch. After the switch is
turned on, the LED indicators should respond as follows:
❑
All of the LED indicators will blink momentarily. This blinking of the
LED indicators represents a reset of the system.
❑
The FDX/Col LED indicators blink from yellow to green.
❑
The power LED indicator will remain ON.

Installation
Site Requirements
Make sure you observe the following site requirements:
❑
Place the switch in a dust-free and moisture-free environment.
❑
Do not block ventilation openings on the unit. Make sure there is
proper heat dissipation from and adequate ventilation around the
switch.
❑
Make sure the AT-FS704 power is accessible and cables can be
connected easily. Use dedicated power circuits or power conditioners
to supply power to the unit, and make sure that the power cord is fully
inserted in the AC power connector.
❑
The power outlet should be within 1.82 m (6 ft) of the device.
❑
Cabling should be away from sources of electrical noise such as radios,
transmitters, broadband amplifiers, power lines and fluorescent
fixtures.
❑
Do not place objects on top of the switch.
❑
Ensure the surface supports at least 1.2 Kg.
Desktop Installation
When installing the AT-FS704 on a desktop or shelf, first attach the rubber feet
included with the device. Attach these cushioning feet on the bottom at each
corner of the device. Allow enough ventilation space between the device and the
objects around it. See Figure 5 for placement of rubber feet.

AT-FS704 Installation Guide
Wall Installation
The AT-FS704 comes with a wall mount kit. This kit includes two screws and
two plastic anchors. For a proper placement on the wall, follow these
installation requirements:
❑
Select a site that is free of obstructions from other equipment or
devices. Consider the following points for site selection:
— The switch should be placed high enough so that LED indicators
can be observed and cable and power connections can be made.
— Now is the time to decide whether you want the switch placed with
the front panel facing up or to the side.
❑
Drill two holes into the wall the same distance apart as the screw
support holes located on the bottom of the switch. Do not drill these
holes too deep.
❑
Insert the plastic anchors into the holes in the wall and secure them
with gentle hammer taps.
❑
Insert the screws provided with the wall mount kit into the plastic
anchors and partially screw them in. Do not insert the screws with
excessive torque. Note that the screw head along with a small portion
of the screw body should be sticking out.
❑
Gently place the switch onto the wall with the front panel facing up or
down by sliding the screws into the provided slots.
❑
Attach all power and network connections at this time, as described in
the Connectivity section, below.
Connectivity
This section describes how to connect the AT-FS704 to your Fast Ethernet
network, including:
❑
PC to Switch

Technical Specifications
Recommended Cables and Cable Specifications
The cable between the switch and the link partner (hub, workstation) must be
less than 100 m (328 ft) long. 10Base-T segments can use 22, 24 or 26-gauge
TP cabling that complies with IEEE 802.3 10Base-T standard for Category 3,
4 or 5. 100Base-TX segments must use IEEE 802.3u compliant Category 5 TP
cable.
The AT-FS200 family of switches use three types of cabling:
❑
UTP/STP cable (RJ45 connector) for both 10/100Base-TX
❑
Fiber optics cable (ST/SC connector) for 100Base-FX
Table 2 provides an overview of IEEE 802.3 and 802.3u cabling specifications
for 10Base-T, 100Base-TX, and 100Base-FX network configurations using
twisted-pair cable and fiber optics.

AT-FS704 Installation Guide
100Base-TX Cable
There are various grades of voice-quality and data-quality cables available.
These can appear to be similar externally, although their high-speed data
transmission characteristics are radically different. The identification problem
is made worse by some suppliers selling voice-quality cables as data-quality
cables.
If voice-quality cables are used in a 100Base-TX network system, data
movement may be slow, collision-prone or non-existent. In addition, interface
LEDs will usually indicate a valid link in such cases.
Category 5 cabling is required for 100Base-TX connections. Using any other
category for a 100Base-TX connection may result in high error rates, or may
not have the capacity to transmit data.
