Chapter 1
Overview
The AT-FS7016 and AT-FS7024 are Layer 2, Fast Ethernet Smart Switches.
These switches offer a range of features and capabilities, including limited
management that simplifies the task of creating or expanding an Ethernet or
Fast Ethernet network.
A Fast Ethernet Smart Switch can be used in a network environment which
requires some configuration and minimum maintenance and monitoring.
The AT-FS7016 switch features 16 10/100Base-TX twisted pair ports. The
AT-FS7024 switch features 24 10/100Base-TX twisted pair ports. Each twisted
pair port has a RJ-45 connector and a maximum operating distance of 100
meters (328 feet). These ports are capable of Auto-negotiating to 10 or 100
Mbps and feature half- and full-duplex operation.
Each switch also features a RS-232 Terminal Port for out-of-band
management.
The AT-FS7016 and AT-FS7024 switches feature an internal power supply and
are designed for desktop or rackmount installation.

Port Speed
The twisted pair ports are 10/100Base-TX compliant and are capable of both 10
Mbps and 100 Mbps speeds. You can set the port speed manually or, since the
ports are IEEE 802.3 Auto-negotiation 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 the port on
the switch and the port on the 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 each twisted pair port on
the switch. To deactivate Auto-negotiation and set the speeds manually,
refer to the AT-S67 and AT-S68 Software Management User’s Guide.
Duplex Mode
The duplex mode refers to the manner in which an end-node sends and receives
data on the network. Depending on its capabilities, an end-node can operate in
either half- or full-duplex mode. An end-node operating in half-duplex can
either send or receive data, but not both at the same time. However, an end-
node operating in full-duplex can send and receive data simultaneously. The
best network performance is achieved when an end-node can operate in full-
duplex mode.
Each twisted pair port on the AT-FS7016 and AT-FS7024 switch can operate
in either half- or full-duplex 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 ports can be disabled so that you
can set the duplex mode manually through the management software.
Note
In order for a port on the switch to successfully Auto-negotiate its duplex
mode with an end-node, the end-node should also be set to Auto-
negotiation. Otherwise, a duplex mode mismatch can occur. A port on the
switch 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 management
software to disable Auto-negotiation on the port and set the port speed
and duplex mode manually.

Overview

Auto MDI/MDI-X
An RJ-45 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. The RJ-45
port on a PC, router, or bridge is typically wired as MDI, while the 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 MDI to MDI-X, you would use a
straight-through twisted pair cable. To connect two network devices that have
the same wiring configuration, such as MDI to MDI, you would use a crossover
cable.
When a port on the AT-FS7016 or AT-FS7024 switch is set to Auto-negotiation,
the switch enables the auto MDI/MDI-X feature. The RJ-45 port automatically
determines the configuration of the port on the device to which it is connected
and then configures itself appropriately. This features allows you to use either
a straight-through or crossover cable when connecting a device to the twisted
pair port.
The auto MDI/MDI-X feature is available only when a port is set to Auto-
negotiation. If Auto-negotiation is disabled, the port defaults to MDI-X. In this
case you would use a crossover cable to connect the port to an end-node with a
MDI-X port (such as another switch).
RS-232 Terminal Port
The RS-232 Terminal Port is used to establish a local (out-of-band)
management session with the switch. To establish a local management session,
you connect either a VT100 terminal or a PC with a terminal emulation
program to the port.
The RS-232 Terminal Port has a DB-9 female connector and uses a straight-
through RS-232 cable (not provided). The default settings for the RS-232
Terminal Port are:
Bits per second: 9600
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None

Note
These default settings are for a DEC VT100 or ANSI terminal, or an
equivalent terminal emulation program.
Power Requirements
The AT-FS7016 and AT-FS7024 switches use a universal internal switching
power supply. Allied Telesyn ships power cords with these units to the U.S.,
Continental Europe, and the U.K. The AT-FS7016 switch requires input of 100
- 240 V AC, 0.8A, 50/60 Hz. The AT-FS7024 switch requires input of 100 - 240
V AC, 0.5A, 50/60 Hz. These switches have a maximum power consumption of
27W.

Network Topologies
The AT-FS7016 and AT-FS7024 Fast Ethernet Smart Switches can be used in
a variety of network topologies. Three types of topologies are described below.
Power Workgroup Topology
A power workgroup topology, shown in Figure 4, allows each end-node to
directly connect to a 10/100Base-TX twisted pair port on an AT-FS7016 switch.
This gives each end-node a dedicated 10 Mbps or 100 Mbps link.

Collapsed Topology
In the topology illustrated in Figure 5, an AT-FS7016 switch 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 end-node that originated the
frame. This reduces the amount of unnecessary data traffic in each workgroup,
freeing up bandwidth and improving network performance.
