Chapter 1

Overview

The AT-FS705PD is a 5-port Unmanaged Fast Ethernet Switch that includes
one Power-Over-Ethernet (POE) port. This switch is considered a Class 1
Powered Device (PD) and can be used in pair with any IEEE 802.3af/D4.3 or
later compliant Power Sourcing Equipment (PSE).

This switch offers a range of features and capabilities that can be used in a
variety of network configurations and topologies. It also serves the following
functions:

❑ Creating small workgroups with dedicated 10 megabits per second

(Mbps) and 100 Mbps links to your network devices, such as
workstations, servers, printers, and routers.

❑ Interconnecting Ethernet hubs or switches to provide a bridge

between the different workgroups of your network.

❑ Connecting to other Ethernet switches so that they can be part of a

larger Ethernet network.

❑ Maximizing your existing network by providing full-duplex operation

over a twisted pair port.

❑ Receiving both data and power through its POE port.

The POE port allows data and power be transmitted over the same single
twisted pair cable without power sourcing consideration or electric rewires.

The AT-FS705PD switch features five 10/100 Mbps twisted pair ports with
one port dedicated for POE operation. Each twisted pair port has an RJ-45
connector with a maximum operating distance of 100 meters (328 feet). The
twisted pair port can operate at 10 Mbps or 100 Mbps and in half- or full­duplex mode.

The AT-FS705PD switch can be used on a desktop or mounted on a wall. The
switch is easy to install and does not require software configuration or
management.

Two ways to power on an AT-FS705PD switch are as follows:

❑ Option 1: Powered by a 24VDC @ 0.3A+ output wall adapter.

Option 1 has higher priority, if both options are connected to the
AT-FS705PD, then it is powered by Option 1 and the PWR WALL LED
is green. In the same time, the PWR POE LED is either blinking or
OFF, which is fully controlled by the Power Sourcing Equipment
(PSE).

❑ Option 2: Powered-over-Ethernet on Port 5.

Option 2 will be enabled only if an IEEE 802.3af compliant PSE is
connecting to Port 5, and no power plug is inserted in the 24VDC
power port.

Caution

POE and power cord are used as disconnection devices: To de-energize
equipment, disconnect the POE and the power cord.

Note

The AT-FS705PD Switch is classified as IEEE Std 802.3af-2003,
Environment A, where a LAN or LAN segment, with all its associated
interconnected equipment, is entirely contained within a single low­voltage power distribution system and within a single building.

Twisted Pair Ports

The AT-FS705PD switch has five 10Base-T/100Base-TX twisted pair ports.
Each twisted pair port features a RJ-45 connector. The maximum operating
distance for the twisted pair ports is 100 meters (328 feet) when operating at
either 10 Mbps or 100 Mbps.

4

AT-FS705PD Fast Ethernet Switch Installation Guide

Port Speed

The twisted pair ports are compliant with the 10Base-T and 100Base-TX
standards and are capable of either 10 Mbps or 100 Mbps operation. Since the
ports are IEEE 802.3u Auto-Negotiation compliant, the switch will set the
port speed automatically. With Auto-Negotiation, the speed of the ports are
set automatically by the switch after it determines the speed of the end-node
connected to the port. Auto-Negotiation is designed to ensure that the port on
the switch and the end-node are operating at the same speed and that they
are communicating at the highest possible common speed between the
devices. For example, if an end-node is capable of only 10 Mbps, the switch
then sets the port connected to the end-node to 10 Mbps.

Duplex Mode

Duplex mode refers to the way an end-node sends and receives data on the
network. An end-node can operated in either half- or full-duplex mode
depending on its capabilities. An end-node that is operating in half-duplex
mode can either send data or receive data, but it cannot do both at the same
time. An end-node that is operating in full-duplex mode can send and receive
data simultaneously. The best network performance is achieved when an end­node can operate at full-duplex, since the end-node is able to send and receive
data simultaneously.

Each twisted pair port on the AT-FS705PD switch can operate in either half­duplex or full-duplex mode. Since these twisted pair ports are IEEE 802.3u­compliant, the duplex mode can be set automatically through Auto­Negotiation. With Auto-Negotiation, if the end-node is capable of full-duplex,
the port is set automatically to full-duplex mode. If the end-node is capable of
half-duplex, the port is set automatically to half-duplex mode.

Note

In order for a twisted pair port on the AT-FS705PD switch to
successfully Auto-Negotiate its duplex mode with an end-node, the end­node should also be using Auto-Negotiation. Otherwise, a duplex mode
mismatch can occur. The twisted pair port, using Auto-Negotiation, will
default to half-duplex if it detects that the end-node is not using Auto­Negotiation. This will result in a mismatch if the end-node is operating
at a fixed duplex mode of full-duplex.

Overview

Auto MDI/MDI-X

A twisted pair port on a 10 Mbps or 100 Mbps Ethernet network device can
have one of two possible wiring configurations: MDI or MDI-X. A twisted pair
port on a PC, router, or bridge is typically wired as MDI, while a twisted pair
port on a switch or hub is usually MDI-X.

To connect two 10 Mbps or 100 Mbps network devices together that have
dissimilar port wiring configurations, such as an MDI to MDI-X, you would
use a straight-through twisted pair cable. To connect two networks devices
that have the same wiring configuration, such as MDI to MDI, you would use
a crossover cable.

The AT-FS705PD switch features automatic MDI/MDI-X. The twisted pair
port automatically determines the configurations of the port on the device to
which it is connected and then configures itself appropriately. For example, if
a port on a switch is connected to a port on a bridge, which is typically wired
as MDI, the port on the switch automatically configures itself as MDI-X. This
feature allows you to use either a crossover cable or a straight-through cable
when connecting a device to a twisted pair port.

MAC Address Table

The heart of an Ethernet switch is the Media Access Control (MAC) address
table. Every device that you attach to an Ethernet network has a MAC
address. This address is assigned to the device by the device’s manufacturer.
For example, each Network Interface Card (NIC) that you install into your
network computers has a MAC address that was assigned to it by the card’s
manufacturer.

A switch’s MAC address table is a list of the MAC addresses of the devices
that are connected to its ports. The switch uses this table to direct data frames
to their appropriate destination end-nodes, and in some cases, to discard
frames that it receives. The switch creates the MAC address table by
examining the frames that it receives on its ports. Each frame is examined for
its source address; that is, the MAC address of the end-node that sent the
frame. The switch checks to determine whether the address is already in its
MAC address table. If it is not, the switch adds the address to the table along
with the port number on which the frame was received. The result is a table
that contains a list of all the MAC addresses of end-nodes that have sent
frames to the switch and the ports on the switch to which the end-nodes are
connected.

6

AT-FS705PD Fast Ethernet Switch Installation Guide

The switch also checks the destination MAC address of each frame it receives.
The destination address is the MAC address of the end-node to which the
frame is intended. If the address is in the table, the switch directs the frame
directly to the port where the end-node is located. This helps to ensure that
end-nodes will only receive traffic that is intended for them and not have to
deal with traffic intended for other end-nodes.

If the destination address is not in the MAC address table, the switch
broadcasts the frame to all switch ports. When the destination end-node
responds, the switch will be able to match the address to a port so that the
next time a frame is destined to that particular end-node, the switch will be
able to forward the frame to the correct port instead of having to broadcast the
frame to all ports.

In some cases a switch will even discard a frame. If the switch receives a
frame that is destined to an end-node on the same port on which the frame
was received, the switch discards the frame.

The MAC address table in the AT-FS705PD switch can store up to 2,048 MAC
addresses. To prevent the table from becoming filled with addresses of end­nodes that are no longer active, the switch has a MAC address aging timer.
This timer will delete a MAC address from the table if it does not see a frame
from the end-node with the address on any port after five minutes (300
seconds). The aging timer also helps to ensure that the table is correct should
an end-node be moved from one port on the switch to another port.

Store and Forward

The AT-FS705PD switch supports store and forward switching at Fast
Ethernet full-wire speed. Packets entering each port are stored in buffers.
Once the full packet is received, the switch will forward or discard the packet,
depending on its destination address and error status. This ensures that only
error-free packets destined for another segment will be transferred across the
switch, reducing network load. For example, if the packet entering from Port 1
is destined for an end-node on Port 2, the switch forwards the frame if the
frame does not contain any errors. If the packet from Port 1 is destined for an
end-node also connected to Port 1, the packet is discarded.

5. Connect the twisted pair cables to the twisted pair ports.

When connecting a twisted pair cable to a port, observe the following
guidelines:

❑ An RJ-45 connector should fit snugly into the port on the switch. The

tab on the connector should lock the connector into place.

❑ You should check to be sure that you are using the appropriate type of

twisted pair cabling. Refer to Table 3 on page 12 for twisted pair cable
specifications.

❑ Since the twisted pair port, when operating in Auto-Negotiation, is

Auto MDI/MDI-X, you can use either a straight-through or crossover
twisted pair cable to connect any type of network device to a port on
the converter.

Caution

POE and power cord are used as disconnection devices: To de-energize
equipment, disconnect the POE and the power cord.

18

AT-FS705PD Fast Ethernet Switch Installation Guide

6. Power ON the switch.

There are two ways to power ON the switch; perform one of the following
steps:

❑ Using a wall power adapter: Plug one end of the power cord to the

24VDC power connector on the back of the switch and the other end of
the power cord to a power outlet.

❑ Using the POE port: Make sure that no power plug is inserted in the

24VDC power port. Then plug one end of the twisted pair cable to the
POE port on the back of the switch and the other end of the twisted
pair cable to an Ethernet port on a PSE device.

7. Verify that either the PWR POE or WALL LED is green. If the LED is
OFF, refer to “Troubleshooting” on page 21 for instructions.

8. Power ON the end-nodes connected to the switch.

9. Check the LINK/ACT LEDs for each port is green. If a LED is OFF, refer
to “Troubleshooting” on page 21 for instructions.

The switch is now ready for use.

Troubleshooting

Follow the guidelines below to test and troubleshoot the installation in the
event a problem occurs.

If the PWR-POE LED is OFF and Port 5 is connected to a PSE device, do the
following;

Note

This twisted pair cable connecting to the POE port must be a Category 5
Ethernet cable.

❑ Make sure that the PSE device is IEEE 802.3af/D4.3 or later

compliant.

❑ Make sure that the PSE device is detecting the AT-FS705PD switch.

❑ Make sure that the CAT5 cable is functional.

❑ Make sure there is no power plug inserted in the 24VDC power port

on the back panel of the switch.

If the PWR-WALL LED is OFF and the AT-FS705PD switch is connected to a
wall adapter, do the following;

❑ Make sure that the wall adapter has an output capability of 24VDC @

0.3A.

❑ Make sure that the wall adapter has the same output polarity as the

one shown on the AT-FS705PD switch, refer to Figure 1 on page 2.

If a LINK/ACT LED is OFF, do the following:

❑ Check that the end-node connected to the port is powered ON and is

operating properly.

❑ Check that the twisted pair cable is securely connected to the port on

the switch and to the port on the end-node.

21

Troubleshooting

❑ Verify that the end-node connected to the port and the switch are

operating at the same speed. Both must be operating at either 10
Mbps or 100 Mbps.

❑ Make sure that the twisted pair cable does not exceed 100 meters (328

feet) and that you are using a Category 3 or better cable for 10Base-T
operation or a Category 5 or better cable for 100Base-TX operation.

If there is a communication problem between the end-nodes connected to the
switch, do the following:

❑ Verify that the end-nodes are operating with the same duplex mode.

If you are still experiencing problems after testing and troubleshooting the
installation, refer to “Contacting Allied Telesyn” on page viii or visit our web
