Chapter 1

Overview

The AT-FS705E FC Series and the AT-FS706E FC Series Fast Ethernet
switches are unmanaged Layer 2 switches. They can be used in a variety of
network configurations and topologies. You can use the switches to create
small workgroups with dedicated 10/100 Mbps links to your network devices,
such as workstations, servers, printers, and routers. You can also use the
switches to interconnect Ethernet hubs to provide a bridge between the
different workgroups of your network. Finally, you can connect the switches to
other Ethernet switches so that they can be part of a larger Ethernet network.

Common features of the switches include:

G

Four 10/100 Mbps (10Base-T / 100Base-TX) twisted pair ports with
RJ-45 connectors

G

One (AT-FS705E FC) or two (AT-FS706E FC) 100 Mbps fiber optic
ports with a maximum operating distance of 2 kilometers (1.25 miles)

G

Full- or half-duplex operation on both the twisted pair ports and the
fiber optic ports

G

Automatic MDI/MDI-X configuration on the twisted pair ports

G

Store and forward Ethernet packet handling

G

MAC address table with a capacity of 4,000 addresses

The AT-FS705E FC Series and the AT-FS706E FC Series Fast Ethernet
switches are easy to operate. They require no software management.

The switches are available with a variety of fiber optic connectors. For a
complete list of the available models, contact your Allied Telesyn
International sales representative.

Note

The AT-FS705E FC Series and the AT-FS706E FC Series switches are
functionally identical. The only difference is the addition of the second
fiber optic port on the AT-FS706E FC Series switch.

10/100 Mbps Twisted Pair Ports

The AT-FS705E FC and AT-FS706E FC switches have four twisted pair ports.

Type of Connector

The twisted pair ports have RJ45 connectors.

Speed

These ports are compliant with the 10Base-T and 100Base-TX standards and
are capable of either 10 Mbps or 100 Mbps operation. The ports are IEEE

802.3u Auto-negotiation-compliant, meaning the speed for each port is set
automatically by the switch after determining the speed of the end node
connected to the port. Auto-negotiation is designed to ensure that each port on
the switch and the end node connected to each port are operating at the same
speed and that they are communicating at the highest possible common speed
of the devices.

Duplex Mode

The twisted pair ports can operate in either half- or full-duplex operation. Just
as with speed, the ports use Auto-negotiation to set the duplex mode. If the
end node is capable of full-duplex mode, the port is set to full-duplex. If the
end node is capable of only half-duplex, the port is set to half-duplex. For an
explanation of duplex mode, refer to the section “Duplex Mode” on page 9.

Cabling

The RJ45 ports on the switch can use shielded or unshielded twisted pair
cable. There are several categories of twisted pair cabling used in Ethernet
networks. They are Category 3, 4, and 5. The main difference between the
categories relates to their attenuation, which is a measurement of signal loss
over the length of the cable. All cables experience attenuation. The signal
loses strength the longer the cable. The lower the loss of signal, the lower the
attenuation.

Of the three categories, Category 3 has the highest attenuation, meaning that
it has the highest signal loss. It is adequate for 10 Mbps operation, but should
never be used for 100 Mbps network operations. The higher speed requires
Category 5. If you are installing a new network with end nodes operating at 10
Mbps, it is recommended that you install Category 5 instead of Category 3.
This will save you the trouble of having to install new twisted pair cabling
should you later upgrade your end nodes to 100 Mbps.

3

Maximum Distance

The maximum distance of a twisted pair cable is 100 meters (328 feet). Cable
lengths that exceed this limit can result in poor or erratic network
performance.

Auto MDI/MDI-X

An RJ45 twisted pair port on a 10 Mbps or 100 Mbps Ethernet network device
can be wired as either MDI and MDI-X. Twisted pair ports on personal
computers, routers, and bridges are typically wired as MDI. The twisted pair
ports on switches and hubs are usually MDI-X.

When connecting two network devices together, you use straight-through
twisted pair cabling when connecting two dissimilar ports together, such as an
MDI port to an MDI-X port. To connect two similar ports together, such as an
MDI port to an MDI port, you use a crossover twisted pair cable.

The twisted pair ports on the AT-FS705E FC and AT-FS706E FC can operate
as either MDI or MDI-X. This feature eliminates the need for using a
crossover cable with the switch. This means that you can use straight-through
twisted pair cabling regardless of the type of end nodes you connect to the
ports. Each port automatically determines the configuration 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.

AT-FS705E FC and AT-FS706E FC Installat ion Guide

100 Mbps Fiber Optic Port

The AT-FS705E FC and AT-FS706E FC Ethernet switches feature one and
two fiber optic ports, respectively. You can use the fiber optic ports to connect
the switch to other switches or other end nodes over large distances.

Type of Connector

The AT-FS705E FC Series and the AT-FS706E FC Series switches come with
a variety of fiber optic connectors. Contact your Allied Telesyn International
sales representative for a list of available connector types.

Speed

The fiber optic port is complaint with the 100Base-FX standard and has a
fixed operating speed of 100 Mbps. This speed cannot be changed; the end
node that you connect to the fiber optic port on the switch must also be able to
operate at 100 Mbps.

Duplex Mode Switch

The fiber optic port(s) is able to operate in either half- or full-duplex mode.
The duplex mode is set with the 100FX DUPLEX switch located on the front of
the switch. The AT-FS705E FC Series has one duplex switch for its one fiber
optic port. The AT-FS706E FC Series has two duplex switches, one for each of
its two fiber optic ports. For an explanation of duplex mode, “Duplex Mode” on
page 9.

Cabling

There are two basic types of fiber optic cabling used in Ethernet networks:
multimode fiber and single-mode fiber. Multimode fiber is for short distances,
typically not more than 2 kilometers (1.25 miles). Single-mode is for longer
distances. The fiber optic port(s) on the Ethernet switch has a maximum
operating distance of 2 kilometers, and is designed to be used with either
54/125 or 60/125 micron core/cladding multimode cable.

Note

Do not use single-mode fiber optic cable with the fiber optic port(s) on
the AT-FS705E FC and AT-FS706E FC Ethernet switches.
