Overview
100Base-FX Fiber Optic Ports
The AT-8016F/MT, AT-8016F/SC, and AT-8016F/ST switches feature 16
fiber optic ports. The AT-8026FC switch have two fiber optic ports. The
AT-8088/MT and AT-8088/SC switches have eight fiber optic ports. The
operating characteristics of the fiber optic ports on all the switches are
the same.
Type of
Connector
The fiber optic ports on the AT-8016F/SC, AT-8026FC, and AT-8088/SC
switches feature SC connectors.
The fiber optic ports on the AT-8016F/ST switch features ST connectors.
The fiber optic ports on the AT-8016F/MT and AT-8088/MT switches
feature MT-RJ connectors.
Speed
The fiber optic ports have a fixed operating speed of 100 megabits per
second (Mbps). The speed cannot be changed.
Duplex Mode
The fiber optic ports can operate in either half- or full-duplex mode. You
can set the duplex mode manually or allow the switch to set it
automatically through Auto-Negotiation.
Maximum
Distance
Each fiber optic port has a maximum operating distance of 2 kilometers
(1.25 miles) when operating in full-duplex mode and 412 meters (1,360
feet) when operating in half-duplex mode.
Type of Cable
The fiber optic ports can use either 50/125 or 62.5/125 micron
multimode fiber optic cable.
Note
Do not use single-mode fiber optic cable with these ports.
22
AT-8000 Series Fast Ethernet Switches Installation Guide
10/100Base-TX Twisted Pair Ports
The twisted pair ports featured on the AT-8000 Series Switch are
described below.
Type of
Connector
Speed
All twisted pair ports feature 8-pin RJ-45 connectors. For the port
pinouts, refer to RJ-45 Twisted Pair Port Pinouts on page 84.
The twisted pair ports are 10/100Base-TX compliant and are capable of
both 10 megabits per second (Mbps) and 100 Mbps speeds. You can set
the port speed manually or, since the ports are IEEE 802.3u AutoNegotiation compliant, you can let the switch set each port’s speed
automatically. With Auto-Negotiation, the switch automatically matches
the highest possible common speed between each switch port and each
end-node. For example, if an end-node is capable of only 10 Mbps, the
switch sets the port connected to the end-node to 10 Mbps.
Note
Auto-Negotiation is activated as the default on all twisted pair ports
on the switch. To deactivate Auto-Negotiation and set the speeds
manually, refer to the AT-S39 Management Software User’s
Guide.
Duplex Mode
Each twisted pair port on the switch can operate in either half- or fullduplex mode. The twisted pair ports are IEEE 802.3u-compliant and will
Auto-Negotiate the duplex mode setting.
If desired, Auto-Negotiation on one or all of the switch ports can be
disabled so that you can set the duplex mode manually through the
switch’s management software.
Note
In order for a switch port to successfully Auto-Negotiate its duplex
mode with an end-node, the end-node should also be using AutoNegotiation. Otherwise, a duplex mode mismatch can occur. A
switch port, using Auto-Negotiation, will default to half-duplex if it
detects that the end-node is not using Auto-Negotiation. This will
result in a mismatch if the end-node is operating at a fixed duplex
mode of full-duplex. Consequently, when connecting an end-node
with a fixed duplex mode of full-duplex to a switch port, you should
use the AT-S39 management software to disable Auto-Negotiation
on the port and set the port speed and duplex mode manually.
Maximum
Distance
Each twisted pair port has a maximum operating distance of 100 meters
(328 feet).
23
Overview
Type of Cabling
For 10 Mbps operation, Category 3 or better 100 ohm shielded or
unshielded twisted pair cabling is required. For 100 Mbps operation,
Category 5 or Enhanced Category 5 (5E) 100 ohm shielded or unshielded
twisted pair cabling is required.
Auto MDI/
MDI-X
The twisted pair ports are auto-MDI/MDI-X. They automatically
configure themselves as either MDI or MDI-X. This feature allows you to
use either straight-through or crossover twisted pair cables to connect
devices to the ports.
Note
Disabling Auto-Negotiation on a port also disables Auto MDI/MDI-X
on the port. You must set the MDI/MDI-X manually through the
management software, refer to the AT-S39 Management
Software User’s Guide.
Port Pinouts
24
Refer to Table 9 on page 84 and Table 10 on page 84 for the port pinouts.
AT-8000 Series Fast Ethernet Switches Installation Guide
10/100/1000Base-T Twisted Pair Ports
The two twisted pair 10/100/1000Base-T ports featured on the AT-8026T
are described below.
Type of
Connector
Speed
Duplex Mode
The ports have 8-pin RJ-45 connectors. The ports use four pins when
operating at 10 or 100 Mbps and all eight pins when operating at
1000 Mbps.
The ports can operate at 10, 100, or 1000 Mbps. The speed is set
automatically through Auto-Negotiation or you can set the speed
manually through the management software.
The ports can operate in either half- or full-duplex mode. The ports are
IEEE 802.3u compliant and will Auto-Negotiate the duplex mode. If
needed, Auto-Negotiation can be disabled so that you can set the
duplex mode manually through the management software.
Note
In order for a switch port to successfully Auto-Negotiate its duplex
mode with an end-node, the end-node should also be using AutoNegotiation. Otherwise, a duplex mode mismatch can occur. A
switch port, using Auto-Negotiation, will default to half-duplex if it
detects that the end-node is not using Auto-Negotiation. This will
result in a mismatch if the end-node is operating at a fixed duplex
mode of full-duplex. Consequently, when connecting an end-node
with a fixed duplex mode of full-duplex to a switch port, you should
use the AT-S39 management software to disable Auto-Negotiation
on the port and set the port speed and duplex mode manually.
Maximum
Distance
The ports have a maximum operating distance of 100 meters (328 feet).
Type of Cable
For 10 Mbps, the port requires Category 3 or better 100 ohm shielded or
unshielded twisted pair cabling. For 100 or 1000 Mbps operation, the
ports require Category 5 or Enhanced Category 5 (5E) 100 ohm shielded
or unshielded twisted pair cabling.
25
Overview
Auto MDI/
MDI-X
The ports are auto-MDI/MDI-X. They automatically configure themselves
as either MDI or MDI-X. This feature allows you to use either straightthrough or crossover twisted pair cables to connect devices to the ports.
Note
Disabling Auto-Negotiation on a port also disables Auto MDI/MDI-X
on the port. You must set the MDI/MDI-X manually through the
management software, refer to the AT-S39 Management
Software User’s Guide.
Port Pinouts
26
For the pinouts of these ports when operating at 10 or 100 Mbps in the
MDI configuration, refer to Table 9 on page 84. For the pinouts of the
ports when operating at 10 or 100 Mbps in the MDI-X configuration,
refer to Table 10 on page 84. For port pinouts when the ports are
operating at 1000 Mbps, refer to Table 11 on page 85.

A Few Basics about Ethernet Switching
An Ethernet switch interconnects network devices, such as workstations,
printers, routers, and other Ethernet switches, so that they can
communicate with each other by sending and receiving Ethernet
frames.
MAC Address
Table
Most of the hardware devices on your network have a unique MAC
address. This address is assigned to a device by the device’s
manufacturer. For example, when you install a Network Interface Card
(NIC) in a computer so that you can connect it to the network, the NIC
already has a MAC address assigned to it by its manufacturer.
An AT-8000 Series Fast Ethernet Switch has a MAC address table of
4 kilobytes. The switch uses the table to store the MAC addresses of the
network end-nodes connected to the ports, along with the port number
on which each address was learned.
A switch learns the MAC addresses of the end-nodes by examining the
source address of each packet received on a port. It adds the address
and port on which the packet was received to the MAC table if the
address had not already been entered in the table. The result is a table
that contains all the MAC addresses of the devices that are connected to
the switch’s ports, and the port number where each address was
learned.
When the switch receives a packet, it also examines the destination
address and, by referring to its MAC address table, determines the port
on which the destination end-node is connected. It then forwards the
packet to the appropriate port and on to the end-node. This increases
network bandwidth by limiting each frame to the appropriate port when
the intended end-node is located, freeing the other switch ports for
receiving and transmitting data.
If the switch receives a packet with a destination address that is not in
the MAC address table, it floods the packet to all the ports on the switch.
If the ports have been grouped into virtual LANs, the switch floods the
packet only to those ports which belong to the same VLAN as the port
on which the packet was received. This prevents packets from being
forwarded into inappropriate LAN segments, increasing network
security. When the destination an end-node responds, the switch adds
its MAC address and port number to the table.
39
Overview
If the switch receives a packet with a destination address that is on the
same port on which the packet was received, it discards the packet
without forwarding it on to any port. Since both the source end-node
and the destination end-node for the packet are located on the same
port on the switch, there is no reason for the switch to forward the
packet.
Duplex Mode
Duplex mode refers to how an end-node receives and transmits data. If
an end-node can receive or transmit data, but not both simultaneously,
the end-node is operating in what is referred to as half-duplex mode. If
an end-node can both receive and transmit data simultaneously, the
end-node is said to be operating in full-duplex mode. Naturally, an endnode capable of operating in full-duplex can handle data much faster
than an end-node that can only operate in half-duplex mode.
The twisted pair ports on the AT-8000 Series Switches can operate in
either half- or full-duplex mode. The twisted pair ports are IEEE 802.3ucompliant and will Auto-Negotiate the duplex mode setting for you.
By allowing the switch to configure the duplex mode for each port itself,
you will not need to change the setting for a port on the switch should
you replace an end-node with an end-node that has a different duplex
mode capability. With Auto-Negotiation, the switch will automatically
reset the port to a new duplex mode setting for you.
If desired, Auto-Negotiation on the switch ports can be disabled so that
you can set the duplex mode manually through the switch’s
management software.
Note
In order for a switch port to successfully Auto-Negotiate its duplex
mode with an end-node, the end-node should also be using AutoNegotiation. Otherwise, a duplex mode mismatch can occur. A
switch port, using Auto-Negotiation, will default to half-duplex if it
detects that the end-node is not using Auto-Negotiation. This will
result in a mismatch if the end-node is operating at a fixed duplex
mode of full-duplex. Consequently, when connecting an end-node
with a fixed duplex mode of full-duplex to a switch port, you should
use the AT-S39 management software to disable Auto-Negotiation
on the port and set the port speed and duplex mode manually.

AT-8000 Series Fast Ethernet Switches Installation Guide
Store and
Forward
Backpressure
and Flow
Control
These Fast Ethernet Switches use store and forward as the method for
receiving and transmitting frames. When an Ethernet frame is received
on a switch port, the switch does not retransmit the frame out the
destination port until it has received the entire frame and stored the
frame in a port buffer. It then examines the frame to determine if it is a
valid frame. Invalid frames, such as fragments or runts, are discarded by
the switch. This insures that only valid frames are transmitted out the
switch ports and that damaged frames are not propagated on your
network.
In order to maintain the orderly movement of data between the endnodes, an Ethernet switch may periodically need to signal an end-node
to stop sending data. This can occur under several circumstances. For
example, if two end-nodes are operating at different speeds, the switch,
while transferring data between the end-nodes, might need to instruct
the faster end-node to stop transmitting data to allow the slower endnode to catch up. An example of this would be when a server operating
at 100 Mbps is sending data to a workstation operating at only 10 Mbps.
How a switch signals an end-node to stop transmitting data differs
depending on the speed and duplex mode of the end-node and switch
port. A twisted pair port operating at 100 Mbps port and half-duplex
mode stops an end-node from transmitting data by forcing a collision. A
collision on an Ethernet network occurs when two end-nodes attempt to
transmit data using the same data link at the same time. A collision
causes end-nodes to stop sending data. When the switch needs to stop a
100 Mbps, half-duplex end-node from transmitting data, it forces a
collision on the data link, which stops the end-node. Once the switch is
ready to receive data again, the switch stops forcing collisions. This is
referred to as backpressure.
A port operating at 100 Mbps and full-duplex mode uses PAUSE frames,
as specified in the IEEE 802.3x standard, to stop the transmission of data
from an end-node. Whenever the switch wants an end-node to stop
transmitting data, it issues this frame. The frame instructs the end-node
to cease transmission. The switch continues to issue PAUSE frames until
it is ready again to receive data from the end-node. This is referred to as
flow control.

Overview
Network Topologies
This section illustrates several of the network topologies you can create
with the AT-8000 Series Fast Ethernet Switches.
Power
Workgroup
Topology
The topology shown in Figure 13 is commonly referred to as a power
workgroup topology. Each workstation or end-node is connected
directly to a port on an AT-8024 Fast Ethernet Switch. Each end-node has
a dedicated data link to the switch for best performance and reliability.
The devices can operate at either 10 Mbps or 100 Mbps.

Topology
In the topology illustrated in Figure 14, an AT-8024 connects together
10/100 Mbps Ethernet hubs. This type of topology is often referred to as
a collapsed backbone topology. The switch functions as the focal point
of the network by acting as a bridge between the different workgroups.
The switch transfers an Ethernet frame from hub to hub only when the
destination end-node for the frame is on a different hub than the endnode that originated the frame. This reduces the amount of unnecessary
data traffic in each workgroup, freeing up bandwidth and improving
network performance.

Mixed Topology
You can always combine topologies as well as build a larger network by
connecting different switches together. If the switches are within 100
meters (328 feet) of each other, you can use the twisted pair ports. If the
switches are further apart, then you will need to use fiber optic ports.
Figure 15 illustrates a network of three AT-8026FC Fast Ethernet
Switches. The workstations and servers of the network are connected
either directly to a switch or through an Ethernet hub. The switches
themselves are connected through their fiber optic ports, which have a
maximum operating distance of 2 kilometers (1.24 miles). The figure also
illustrates how you can use the fiber optic ports to connect other remote
devices to the network, such as remote servers and workstations.

Backbone Switch
Topology
If you need to connect together multiple switches and the switches are
physically separated by more than 2 kilometers (1.24 miles), or if you
want to build a 1000 Mbps backbone network between switches, you
can use AT-8024GB Fast Ethernet Switches and install fiber optic GBIC
modules. The modules span large distances and, with an operating
speed of 1000 Mbps, can provide a fast backbone between the switches.
Figure 16 illustrates another collapsed backbone topology, this time
using a high speed, fiber optic 1000Base Ethernet switch as the focal
point. Six AT-8024GB Ethernet Switches, each with a GBIC module, are
interconnected via a Gigabit Ethernet switch.

Selecting a Site for the Switch
Observe the following requirements when choosing a site for your
switch:
48
If you plan to install the switch in an equipment rack, check to be
sure that the rack is safely secured and that it will not tip over.
Devices in a rack should be installed starting at the bottom, with
the heavier devices near the bottom of the rack.
If you are installing the switch on a table, be sure that the table is
level and secure.
The power outlet for the switch should be located near the unit
and should be easily accessible.
The site should provide for easy access to the ports on the front of
the switch. This will make it easy for you to connect and
disconnect cables, as well as view the switch’s LEDs.
To allow proper cooling of the switch, air flow around the unit and
through its vents on the side and rear should not be restricted.
Do not place objects on top of the switch.
Do not expose the switch to moisture or water.
Make sure that the site is a dust-free environment.
You should use dedicated power circuits or power conditioners to
supply reliable electrical power to the network devices.

Installation
Cabling and Powering ON the Switch
Perform the following procedure to connect the data cables to the
switch ports and to apply power to the switch.
1.
If your AT-8000 Series Switch has twisted pair ports, connect the
twisted pair data cables to the RJ-45 ports on the switch, as shown
in Figure 29.
Figure 29 Connecting the Twisted Pair Data Cables
When connecting a twisted pair cable to a port, observe the
following guidelines:
62
❑
An RJ-45 connector should fit snugly into the port on the
switch. The tab on the connector should lock the connector
into place.
❑
Since the ports on the switch are 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 switch.
❑
If your network topology will contain a loop where two or
more network devices can communicate with each other over
more than one data path, do not connect the network cables
forming the loop until after you have activated the Spanning
Tree Protocol (STP) on the switch. Data loops can adversely
affect network performance. For instructions on how to
activate STP, refer to the AT-S39 Management Software
User’s Guide.
AT-8000 Series Fast Ethernet Switches Installation Guide
❑
2.
If you are creating a port trunk, do not connect the cables of
the trunk to the switch until you after have configured the
trunk using the switch’s management software. Connecting
the trunk cables to the switch before you have configured the
software will result in a data loop, which can adversely affect
network performance. For instructions on how to configure a
port trunk, refer to the AT-S39 Management Software
User’s Guide.
If your switch has fiber optic ports, remove the dust covers from the
ports.

(328 ft).
Verify that you are using the appropriate category of twisted pair
cable: Category 3 or better for 10 Mbps operation and Category 5
and Category 5E for 100 Mbps and 1000 Mbps operations.
Make sure that the operating parameters of the port on the switch
are compatible with the end-node to which the port is connected.
This will require using the switch’s management software. For
instructions, refer to the AT-S39 Management Software User’s
Guide.
For fiber optic ports, verify that the LINK LED for each port is ON. If a LINK
LED is OFF, do the following:
Verify that the end-node connected to the port is powered ON
and is operating properly.
Check that the fiber optic cable is securely connected to the port
on the switch and to the port on the end-node.
ST and SC ports consist of two separate connectors, as shown in
Figure 32 on page 64. Each connects to a separate fiber strand.
One is for receiving data and the other is for transmitting data.
When connecting a fiber optic cable to a ST or SC port, be sure
that the receiver fiber connector is connected to the transmitter
connector on the remote end-node, and the transmitter fiber
connector is connected to the receiver connector on the remote

Expansion Module Installation Guide.)
Check that the operating specifications (for instance, wavelength
and maximum operating distance) of the fiber optic port on the
remote end-node are compatible with the fiber optic port on the
switch. For example, you cannot connect a fiber optic port with a
maximum distance of 40 kilometers (24.8 miles) and an operating
wavelength of 1550 nm to a remote fiber optic port with an
maximum distance of only 2 kilometers (1.24 miles) and a
wavelength of 1310 nm.
Check to be sure that the fiber optic ports on the switch and on
the end-node are operating at the same speed and duplex mode.
AT-8024GB switch only — Verify that the GBIC module is
completely inserted into the GBIC expansion slot on the front of
the switch.
Note
A 1000Base connection can take from five to ten seconds for the
link to be established.
If the FAULT LED is blinking, no action is required. A blinking FAULT LED
could indicate that a new version of the management software is being
downloaded to the switch or that the switch’s configuration is being
changed, such as with the creation of a new VLAN. The LED will stop
blinking once the switch has completed the download or its
reconfiguration.
If the FAULT LED is constantly ON, a problem has occurred in the switch.
Do the following:
