Chapter 1
Hardware Description
The AT-8316F and the AT-8324 switches are designed to provide
your network with Ethernet, Fast Ethernet, and Gigabit Ethernet
connectivity over fiber optic and twisted pair cabling.
The switches can operate as standalone units or can be
interconnected together through special stacking ports to form
logical switches. Logical switches, also referred to as s tacks, can make
it easier for you to manage your network because you can manage
all of the switches as one unit. Logical switches are also easy to
customize. You can add or remove switches from a logical switch so
that the unit always has the number and types of ports that your
network requires.
Two expansion slots on the front of the switches further add to the
flexibility of the systems. You can use the slots to install 10Base-T,
100Base-TX, 100Base-FX, and 1000Base-FX expansion modules.
This chapter describes the hardware features of the following
products:
# AT-8316F/MT switch
# AT-8316F/VF switch
# AT-8316F/SC switch
# AT-8324 switch
# The optional expansion modules: AT-A15/SX, AT-A15/LX,
AT-A16, AT-A17, AT-A18, and AT-A19

This method for accessing the Omega program is referred to as “local
access” or “out-of-band” access. You can also access the program
over the web with a web browser or remotely via Telnet or an SNMP
management program.
In an IP environment, after you have initially installed the switch you
will be required to access the Omega program through the RS232
port in order to assign the switch its IP address and, if necessary, a
gateway address. Once these addresses have been assigned, you can
either continue to manage the switch through the RS232 port or
access the program via one of the other available methods.
Note
Only the RS232 port on the master switch in a stack can be used to
configure a stack locally. The RS232 ports on the slave switches are
inactive and cannot be used. (For an explanation of master and
slave switches, refer to , Chapter 3, Installing the Switch.)
Additionally, a straight-through cable is required in order to
connect a terminal to the RS232 port on the master switch.

AT-8316F and AT-8324 Installation Guide
On the back of the switch are two stacking ports (Figure 1-7). The
ports are used to interconnect AT-8316F and AT-8324 switches to
form logical switches. A logical switch consists of two or more
individual switches that function as one unit. This feature allows you
to build a switch that is customized to the needs and requirements of
your network. It also makes it easier to manage them since, rather
than having to mange the switches individually, you can manage all
the switches as one unit.
Stacking Ports
Figure 1-7 Stacking Ports
Interconnecting two or more AT-8316F or AT-8324 switches creates
what is referred to as a stack. A stack can consist of either the same
type of Ethernet switches or different types of switches. For example,
a stack can consist of a combination of AT-8316F/MT and AT-8324
switches. The result would be one logical switch, where the
individual switches themselves were different in the number and
types of ports.
Each stacking port provides two gigabits of full-duplex bandwidth
between switches. A stack of two or three switches does not require
any additional hardware other than the switches and the
AT-CABLE-4 cables that comes with the units. Creating a stack of four
to eight switches requires the optional AT-Stack8 Stacking Matrix
Module.

The capabilities of the AT-8316F and AT-8324XL Ethernet switches
can be expanded by installing optional expansion modules in the
two expansion slots on the front of the switches (shown in Figure
1-9).
The modules offer you flexibility in building or expanding your
network. For example, you can use the modules to build a highspeed backbone network between different switches, to expand the
number of ports on a switch for additional nodes, or to provide a
high-speed connection to shared devices, such as servers or routers.

module in one expansion slot and an AT-A18 module in the second
expansion slot of the same switch.

R.P.S Input Connector
On the back panel of the Ethernet switch is a connector labelled
R.P.S. Input (shown in Figure 1-11). This connector is used to connect
the switch to a redundant power supply (RPS) unit. The RPS shares
the load of powering the switch with the standard power supply that
comes with the Ethernet switch. If one power supply fails, the
remaining unit provides all power to the switch, thus protecting the
switch from a system failure.
AT-8316F and AT-8324 Installation Guide
R.P.S Input Connector
Figure 1-11 R.P.S Input Connector
Allied Telesyn offers the AT-RPS8000 redundant power supply
system for the AT-8316F and AT-8324 switches. The RPS system
comes with one redundant power module pre-installed that can
support one Ethernet switch. The AT-RPS8000 unit has three
expansion slots for three additional redundant power modules, each
of which can support an additional switch. Contact your Allied
Telesyn representative for more information about the AT-RPS8000
redundant power supply unit.

Hardware Description
Reset Button
The Reset button on the front panel of the switch resets the switch. It
is primarily used for diagnostics or resetting the switch statistics
stored by the AT-S25 management software. You can also reset the
switch using the Omega management interface, as explained in the
AT-S25 Management Software User’s Guide. This guide is
available from the Allied Telesyn web site at www.alliedtelesyn.com/
techhome.htm.
Note
If it becomes necessary to reset a switch that is a part of a stack, you
must reset all of the switches in the stack. You cannot reset just one
switch in a stack. Additionally, you should reset the slave switches
first, then the master switch. For information on slave and master
switches, refer to Chapter 3, Installing the Switch.
24
AT-8316F and AT-8324 Installation Guide
AC Power Connector
The switch has a single AC power supply socket on the back panel,
which has autoswitch AC inputs. The input voltage range is from
100-120/200-240 VAC, 4/2A, 50/60 Hz. The power cord acts as an ON/
OFF switch.
AT-S25 Management Software and Omega Management Interface
The AT-S25 software is the management program for the switch, and
it comes pre-installed on the unit. Included with the AT-S25 software
is the Omega management interface. This menu oriented interface
makes it easy for you to manage the system. With Omega, you can
perform all of the tasks necessary to configuring and monitoring the
system, such as creating VLANs, assigning operational parameters to
the switch, such as an IP address and gateway address, and viewing
switch statistics, all through menu selections and easy-to-use
windows.
In a network environment where you have created a stack of
Ethernet switches, you will use the Omega management interface to
manage all of the switches in the stack as a unit, that is, as one logical
switch. You will not manage each switch in a stack separately.
There are several different methods for accessing the Omega
management interface on an Ethernet switch:
# RS-232 connector on the switch
# Web browser
# Telnet program
# SNMP network management program
The Omega interface functions the same and has the same
capabilities regardless of the method you choose to access it. The
program has security features that allow you to disable one or more
of the access methods to prevent unauthorized access to a switch.
The program also has a password security feature.
Note
For instructions on how to access and how to use the Omega
management interface, refer to the AT-S25 Management
Software User’s Manual. This guide is available from the Allied
Telesyn web site at www.alliedtelesyn.com/techhome.htm.

Hardware Description
Network Topology
Figure 1-12 is an example of a network consisting of AT-8316F and
AT-8324 Ethernet switches. Some of the features of the network
include the following:
# Though the Sales and Technical Support workgroups are
distributed between several sites, the 802.1Q VLAN
capabilities of the switches allow you to easily separate their
traffic, improving network performance and enhancing
network security as well.
# The stack of four switches at site 1 are interconnected with an
AT-Stack8 stacking module.
# Port trunking at site 1 provides 200 Mbps of full-duplex
operation to the network servers in the server farm.
# Expansion modules in the switches provide interconnections
between the various sites. For example, site 1 and site 2 each
have AT-A15/LX expansion modules to provide 1000Base-LX
performance up to a maximum distance of 10 kilometers (6.2
miles).

Switch Stacks
AT-8316F and AT-8324 Installation Guide
On the back panel of the Ethernet switches are two stacking ports.
You use these ports to interconnect switches together to create a
stack. A stack of switches functions as one logical switch, rather than
as individual units.
A stack can consist of from two to eight switches. As explained in the
following sections, building a stack or two or three switches does not
require any additional hardware. A stack of from four to eight
switches requires the optional AT-St ac k8 module.
Stack of Two or
Three Switches
Creating a stack of two or three Ethernet switches requires no
additional hardware other than the AT-CABLE-4 cable that comes
with the switches. Figure 2-1 illustrates two Ethernet switches that
have been interconnected through the stacking ports to form a
logical switch.

In order to create a stack of from four to eight AT-8316F or AT-8324
Ethernet switches, you need the optional AT-Stack8 Stacking Matrix
Module (show in Figure 2-3). This module has eight ports, each
providing two gigabits of full-duplex bandwidth. Each stack requires
only one stacking module. You install the module into one of the
switches of the stack and then connect all of the switches to the
module using the AT-CABLE-4 cables.

Expansion Modules
AT-8316F and AT-8324 Installation Guide
If you are building a stack of Ethernet switches, it is important to
know that the more switches in the stack, the fewer number of
expansion modules allowed. (This relates to the number of device
identification numbers that are available to the switches.)
Table 2-2 lists the number of expansion modules that you can install
in stacks of one to eight switches. For example, for a stack of six
switches you could install a total of eight expansion modules. The
expansion modules themselves can be installed in any switch in a
stack, and in any order.

Port Trunking
AT-8316F and AT-8324 Installation Guide
As explained in Chapter 1, port trunking, also referred to as “link
aggregation,” is an economical way for you to increase the
bandwidth between an AT-8316F or AT-8324 switch and another
network device, such as a server, router, workstation, or another
switch. A port trunk is two or more data ports that have been
grouped together to increase the bandwidth between a switch and a
network node. This increase in bandwidth can prove useful in
situations where a single connection between the switch and
another node is insufficient to handle the traffic load.
When ports are trunked together, they act as one logical path. The
increase in bandwidth is equal to the port speed times the number of
ports trunked together. For example, if you were to trunk together
four 100 Mbps ports, the result would be 400 Mbps of bandwidth.
The AT-8316F and AT-8324 switches allow you to trunk together two,
four, or eight ports, providing 200 Mbps, 400 Mbps, or 800 Mbps of
throughput. You can also trunk the ports on an expansion module to
increase the bandwidth from an expansion module to another
network device.
Guideline 1:
Number of
Ports in a Trunk
Guideline 2:
Using Ports
from the Same
Group
When implementing a port trunk, you will need to observe the
following guidelines:
The number of ports in a port trunk must be 2, 4, or 8 ports.
The ports on the Ethernet switches are divided into groups. When
choosing ports for a port trunk, the selected ports must be members
of the same group. You cannot create a port trunk consisting of ports
from different groups.
The ports on an AT-8324 switch are divided into five groups, as
illustrated in Figure 2-4.

Figure 2-6 Port Groups on an AT-8316F/SC Switch
As mentioned previously, the ports for a port trunk must be
members of the same group. A port trunk cannot consist of ports
from different groups. For example, you could use ports 4 and 5 on
an AT-8324 switch as one port trunk, and this would be valid since
the ports are members of the same group. However, ports 7, 8, 9, and
10 cannot be combined to form one port trunk on an AT-8324 switch
because these ports belong to different groups.
Guideline 3:
Creating Only
One Trunk Per
Group
Guideline 4:
Using
Consecutive
Ports
36
Each group of ports on an Ethernet sw itch can suppo rt only one po rt
trunk. For example, the AT-8324 Ethernet switch has three port
groups, assuming no expansion modules. Consequently, this switch
can support three port trunks, one port trunk for each port group.
The addition of two expansion modules would enable the switch to
support two additional port trunks, one for each module.
The ports of a trunk must be consecutive. For example, you could use
ports 4, 5, 6, and 7 as one port trunk, and this would be valid because
the ports are consecutive. However, an invalid selection of ports for a
trunk would be 1, 3, 5, and 7 since these ports are not consecutive.
AT-8316F and AT-8324 Installation Guide
Guideline 5:
Cabling Based
on Port Number
Guideline 6:
Using
Expansion
Modules
When cabling a trunk, it is important that the order of the
connections be identical on both nodes. The lowest numbered port
in a trunk must be connected to the lowest numbered port on the
trunk on the other device, the next lowest numbered port must be
connected to the next lowest numbered port on the other device,
and so on.
For example, assume that you were installing a trunk from an
AT-8316F/SC switch to an AT-8324 switch. On the AT-8316F/SC
switch you had decided to use ports 12, 13, 14, 15 from port group
two for the trunk. On the AT-8324 switch you had chosen ports 21,
22, 23, and 24 from port group 3. To maintain the order of the port
connections, you would connect port 12 on the AT-8316F/SC switch
to port 21 on the AT-8224XL, port 13 to port 22, and so on.
Expansion modules also support port trunking. That is, you can
group the ports on an expansion module together to increase the
bandwidth to the end-node, whether that happens to be another
switch, a server, or router. Table 2-4 lists the number of port trunks
that you can create for each expansion module.
Table 2-4 Trunked Ports on Expansion Modules

Installing the Switch
Building a Stack of Two Switches
To build a stack of two switches, perform the following steps:
1. Select one of the Ethernet switches to be the master switch of the
stack. The other switch will be slave switch. In selecting the master
switch, follow these guidelines:
# The master switch can be either an AT-8316F or AT-8324
switch.
# If the two switches have different versions of the AT-S25 agent
software, select the switch that has the most recent version of
the AT-S25 software as the master switch.
Note
During network operations, the master switch will overwrite the
AT-S25 software in the slave switches with its own version of the
management software. This occurs even if a slave switch contains a
more recent version of the AT-S25 software. For this reason, it is
important that the switch you select to be the master switch have
the most recent version of the management software of all the
switches in the stack.
2. Remove all components from the shipping package and store the
packaging material in a safe location.
3. Locate a level, secure surface for the switches.
Note
If you are building a stack from existing AT-8316F and AT-8324
switches, power OFF the Ethernet switches. If the switches are
connected to an AT-RPS8000 redundant power supply unit, power
OFF the AT-RPS8000 unit using the ON/OFF switch on the back
panel of the unit.

AT-Stack8 Stacking Matrix Module, perform the following steps:
1. Select an AT-8316F or AT-8324 Ethernet switch in which to install
the AT-Stack8 module. This switch will be referred to as the master
switch. The other switches in the stack will be referred to as slave
switches. In selecting the master switch, observe the following
guidelines:
# The AT-Stack8 module can be installed in either an AT-8316F
or AT-8324 switch, even in stacks that will consist of a
combination of AT-8316F and AT-8324 switches.
# If the Ethernet switches have different versions of the AT-S25
software, install the module into the switch that has the most
recent version of the software.
Note
During network operations, the master switch will overwrite the
AT-S25 software in the slave switches with its own version of the
management software. This occurs even if a slave switch contains a
more recent version of the AT-S25 software. For this reason, it is
important that the switch you select to be the master switch have
the most recent version of the management software of all the
switches in the stack.
2. Remove all components from the shipping package and store the
packaging material in a safe location.
3. Locate a level, secure surface for the switches.
Note
If you are building a stack from existing AT-8316F and AT-8324

Note
The Stack ID switch on the master switch must be set to 1.
13. Set the Stack ID switch on each slave switch to match the port
number on the AT-Stack8 module to which the Ethernet switch is
connected.
For example, referring to the stack example in Figure 3-13, the
Stack ID setting for slave switch #1 would be 2 because it is
connected to port 2 on the AT-Stack8 module. The Stack ID
setting for slav e switch #2 woul d be 3 it is connec ted to port 3
on the AT-Stack8 module. The Stack ID numbers for slave
switch #3 would be 6 and the Stack ID setting for slave switch
#4 would be 7.
Note
Do not use the Stack ID settings of 0 (zero) or 9 for any switch in a
stack. These settings are invalid.
14. Connect the data cables to the ports on the front of each switch.
15. Go to the procedure Powering On a Stack on page 3-57.
56
Powering On a Stack
To power on an Ethernet stack, perform the following procedure:
1. Apply AC power to each slave and master switch in the stack by
AT-8316F and AT-8324 Installation Guide
plugging a power cord into the AC power connector on the back
panel of the switch (shown in Figure 3-1) and plugging the other
end into a wall outlet.
To simplify the process, you can connect all of the switches,
both master and slaves, to the same power circuit, such as a
power strip, and so be able to apply power to all of the
switches at the same time. If you power ON the switches
individually, you should apply power to the slave switches
first, and then the master switch.
Caution
The power cord is used as a disconnect device. To de-energize
equipment, disconnect the power cord. "10
As power is applied to a switch, the Fault LED (shown in Figure
3-14) flashes as a series of internal self tests are performed and
as the hardware is configured. Wait for the Fault LED to stop
flashing and remain OFF.

2. Wait while the master switch performs the topology discovery
process. The master switch performs the process in order to
determine the number and types of switches that are in the stack.
During the discovery process, which takes less than one minute to
complete, the port LEDs on each switch will flash in sequence, the
slave switches first and the master switch last.

3. If you purchased a redundant power supply (RPS) unit for the
Ethernet switches, connect the RPS unit to the R.P.S. Input
connectors on the rear of the switch by following the directions
included with the RPS system.
Caution
If you intend to use a redundant power supply (RPS) with the
switch, check to be sure that the cable with the RPS unit is
compatible with the RPS Input Port on the switch. The pin
assignments for the port are provided in Appendix B.
4. Go to the next procedure, Setting Up a Terminal for Local
Management on page 3-59, to access the Omega management
software on the switch.
58
Setting Up a Terminal for Local Management
If you are installing the switch in a TCP/IP environment or if you
intend to manage the switch from a remote site, you must first assign
an IP address to the switch using the Omega management interface,
which comes p re-installed on the switch. This is accomplished by
connecting a terminal (such as a VT100 terminal) or a PC with a
terminal emulation program to the RS232 port on the master switch,
as explained in the following steps:
1. Using an RS232, DB-9 straight-through cable, connect a terminal
or a PC with a terminal emulation program to the RS232
connector on the front panel of the master switch.
Note
Only the RS232 port on the master switch of a stack is active. The
RS232 ports on the slave switches are inactive and cannot be used
to manage a stack.
2. Configure the terminal or the terminal emulation program to the
following settings:
AT-8316F and AT-8324 Installation Guide
# Baud rate: 9600
# Data bits: 8
# Parity: None
# Stop bits: 1
# Flow control: None
3. Press Return.
The switch displays the Omega main menu.
You are now ready to use the Omega management interface
to configure the switch. For instructions, refer to the AT-S25
Management Software User’s Guide. This guide is available
on the Allied Telesyn web site at www.alliedtelesyn.com/

Installing the Switch
Installing an Expansion Module
This section contains the instructions for installing an optional
expansion module in a switch. For information on cabling
specifications for the expansion modules, refer to the section
Expansion Modules on page 2-33.
To install an expansion module, perform the following steps:
1. Disconnect the switch’s power cord, if attached.
Caution
Be sure to disconnect the power cord to the switch before installing
an expansion module. If the switch is connected to a redundant
power supply (RPS) unit, disconnect the switch from the RPS unit as
well. Installing the expansion module with the switch powered ON
can damage the module.
2. Remove a blank faceplate from one of the expansion slots on the
front of the switch by unscrewing the faceplates two captive
screws. Refer to Figure 3-15. Do not remove the blank faceplate if
you are not installing an expansion module in the slot.
A
B
Figure 3-15 Removing the Blank Panel
If you are installing only one expansion module in the switch,
install the module in slot A. While the module will work in slot
B with slot A empty, the port numbering assignments will
change if you later install a module in slot A. This could affect
VLAN memberships on the switch, and this could require you
to adjust your VLAN configurations.
60
AT-8316F and AT-8324 Installation Guide
For example, if you install an AT-A17 in slot B of an AT-8324
switch while leaving slot A empty, the switch will assign the
port numbers 25 and 26 to the ports on the module. If you
later install another AT-A17 in slot A, the switch will
automatically reallocate port numbers 25 and 26 to the new
module in slot A and assign the port numbers 27 and 28 to the
module in slot B. If the module in slot B had been a member of
a VLAN, you would be required to reconfigure the VLAN to
reflect the change to its port numbers.
3. Remove the expansion module from the packing material.
4. Slide the expansion module into the empty slot making sure the
board is aligned properly with the card guides. Refer to Figure
3-16.

Installing the Switch
Resetting a Stack
This section contains the procedure for resetting an AT-8316F or
AT-8324 switch stack.
Note
You cannot reset just one switch in a switch stack. You must reset
the entire stack.
To reset a stack, perform the following procedure:
1. Press the Reset button on the front panel of the slave switches.
2. Press the Reset button on the master switch.
Note
You should reset the slave switches first, before the master switch.
Each switch in the stack will perform a series of internal selftests, indicated by a flashing Fault LED (shown in Figure 3-2).
After a switch has finished running its self tests, the Fault LED
will stop flashing and will remain OFF.
3. Wait while the master switch performs the topology discovery
process. This process is used by the master switch to determine
the number and types of switches that constitute the stack.
During the discovery process, which takes less than one minute to
complete, the port LEDs on each switch will flash in sequence, the
slave switches first and the master switch last.

# Common Problems
65
Troubleshooting
At the First Sign of a Problem
Perform the following tasks when you first become aware of a
problem with the switch:
# Make sure the power cord is securely connected and the
power voltage is not fluctuating.
# Check the data cables for secure connections and make sure
the device at the other end of a connection is operational.
# Reset the stack so that the switches can run self-diagnostics.
For instructions, refer to the section Resetting a Stack on
page 3-62.
# Use Omega to read statistics and run diagnostics. Refer to the
AT-S25 Management Software User’s Guide for further
details on gathering Ethernet statistics and running
diagnostics using the Omega menus.
# If the management software has failed, check the LEDs to see
if the switch continues to forward packets. Then, at a
convenient time, reset the stack, as explained in the section
Resetting a Stack on page 3-62.
# If problems still persist, for example, the Fault LED remains ON,
call Allied Telesyn’s Technical Support or visit Allied Telesyn’s
web site at www.alliedtelesyn.com.
66
Network Cabling Problems
If you have an AT-8324 switch, some network problems may be
related to exceeding cabling distances. Refer to the standard IEEE
802.3u, Clause 29.3.1. 2 o n Worst Case Path Delay Value. This
document specifies that the collision domain diameter must be
within the following limits:
# Under 100 meters (328 feet) for TX cabling
# Under 412 meters (1,332 feet) for half-duplex FX cabling
Calling Technical Support

Troubleshooting
How the Switch Reports Problems
The switch detects and processes errors as follows:
# The LEDs indicate problems with the ports and power. Table
4-1 and Table 4-2 describe the switch LEDs.
# In a TCP/IP environment, if you have configured the software
correctly, the management software triggers an SNMP trap
message. As a result, the software then sends traps to alert the
network manager when a trigger occurs. This type of software
configuration allows the network administrator to proactively
monitor the network.
T able 4-1, Table 4-2, and Table 4-3 list and describe the switch
and expansion module LEDs. As power is applied to the
switch, the Fault LED flashes as the switch runs internal self
tests.
