Introduction

The AT-8116 is a high-performance 10/100Mbps switch representing
the next generation in switching technology. The AT-8116 employs
highly-integrated ASIC technology and a Gigabit/sec backplane to
significantly boost network performance. Its high density and
performance combine with exceptional functionality, such as RMON
support, VLAN capabilities and Full Duplex switching, to achieve
optimal network switching without expensive changes to the desktop
PC or cabling system. The AT-8116 exemplifies the design flexibility
which enables deployment as both a departmental and enterprise
switch, while enhancing network connectivity.

Description

The AT-8116 high-density switch features 16 dual-speed 10/100 UTP
ports with auto-sensing. Highly-integrated ASIC technology enables a
maximum throughput of over 2,000,000pps and 1.6 Gbps.

The switch boasts extensive management capabilities, such as the
ability to access the learning table and per/port counter statistics, and
to set configurations. Built-in RMON support for Groups 1, 2, 3, and 9
allows in-depth analysis of traffic flow, while implementation of the
Spanning Tree Algorithm prevents broadcast loops and provides fail­safe network redundancy.

Introduction

Theory of Operation

Ethernet segment switches divide a large local network into smaller
segments, insulating each from the other’s local traffic and increasing
aggregate bandwidth, while still retaining full connectivity. The AT­8116 is designed to be self-configuring and extremely fast, making
installation simple and providing an increase in available bandwidth.

The switch learns on which port stations are located by remembering
the source address of every packet received on every port. When
packets are received for stations that the switch has learned, they will
be forwarded to only the port on which the station is located. This is in
contrast to a hub, which sends every packet to every port.

If the switch receives a packet addressed to a station which the switch
has not learned, the packet is sent to every port, except the port on
which it was received, just as a hub would. This insures that full
connectivity is maintained. The high port density of the AT-8116 allows
for dedicated high-performance workstation links.

Installing the AT-8116

This section outlines the installation and operation of the AT-8116.
The AT-8116 comes as a 19” rack-mounted unit. However, it can be

placed in either a rack mount, using the enclosed rack-mount brackets,
or on a secure flat surface. Ensure that the unit is within reach of the
necessary connections (i.e. power outlet, Ethernet connections, and, if
the AT-8116 will be monitored via the serial port, a PC, UNIX
workstation, or modem. The unit is powered by a wide-range power
supply for either 115 - 240 VAC 50/60Hz, 0.5 A operation.

Warning

Free air flow must be maintained in order to permit adequate
cooling of the unit. FAN holes MUST be unobstructed.

Installation

Rack Mounting

If rack-mounted units are installed in a closed or multi-rack assembly,
they may require further evaluation by certification agencies. The
following items must be considered:

1. The ambient temperature within the rack may be greater than
room ambient temperature. Installation should be such that the
amount of air flow required for safe operation is not compromised.
The maximum temperature for equipment in this environment is
40°C. Consideration should be given to the maximum rated
ambient temperature.

2. Installation should be such that a hazardous stability condition is
not inadvertently created due to uneven loading.

Network Connections

Connecting an Ethernet Device to a 10Base-T or 100Base-TX Port

The 10/100Base-TX ports on the AT-8116 are designed to be connected
directly to a workstation, using a standard straight-through patch
cable. In order to cascade switches or connect a hub to the switch, a
crossover cable must be used. The RJ45 ports are defined as MDI-X
ports.

The cable connections to the 10/100 ports should be UTP Category 5,
and cable length is limited to 100 meters on each port. Figure 3 and
Figure 4 shows the pin assignments for the RJ45 connector.

Note
Cables must comply with the ANSI/TIA/EIA specification,
commonly referred to as T568A or T568B.

Applications and Configurations

Applications

A switch boosts network performance by segmenting a single large
collision domain into smaller, separate collision domains and providing
dedicated connections for intensive networks using work stations and
servers. In addition, the Full Duplex capability of Ethernet switches
permits connectivity for backbone applications or high throughput for
high-performance dedicated servers. The AT-8116 combines 10/
100Mbps auto-sensing ports with a high-speed backplane design to
enable deployment as both a departmental and backbone switch.

Typical Applications

The AT-8116 seamlessly integrates Fast Ethernet and legacy 10Mbps
Ethernet networks, creates a high-performance collapsed Fast
Ethernet backbone and drives high bandwidth server farms and power
users. Figure 5 illustrates various connection possibilities of the
AT-8116. One switch can connect up to sixteen 10/100Mbps UTP ports.
Attachments can include 10Mbps and 100Mbps servers, a Fast
Ethernet backbone, 10/100Mbps hubs, all functioning in Half or Full
Duplex mode. Port connectivity can be over 10Base-T/100Base-TX
copper cabling. See Figure 5.

Configuring Your Network

Links Between Switches

An Ethernet to Fast Ethernet switch offers the network administrator
a possible upgrade path. At first, the switch can be used simply to
segment the existing 10Mbps Ethernet, immediately boosting
performance. Next, with the addition of a Fast Ethernet NIC, a file
server can be migrated to Fast Ethernet, increasing its availability. As
needed, additional file servers or individual users can be moved to Fast
Ethernet, while leaving all other parts of the network running 10Mbps
as usual. If some of the shared Ethernet segments are still congested,
but don’t warrant a full 100Mbps, additional switches can further
divide the shared segments, creating a collapsed 100Mbps backbone
and small switched 10Mbps segments.

Fast Ethernet provides 10 times the bandwidth than regular Ethernet.
Software, except for low-level drivers which are always card specific,
works with Fast Ethernet without modification. Frames from a device
using Fast Ethernet require only physical layer conversion. The
AT-8116 combines switched 10/100Mbps technology in a seamless
integration of regular Ethernet and the IEEE 802.3u 100Base-TX
standard.

Device Configuration

The AT-8116 provides CLI management. The switch can autosense the
speed for each port. However, the switch must be manually configured
for the correct duplex mode.
