Note

10/100Base-TX Twisted Pair Ports

The switches have 8, 24, or 48 10/100Base-TX ports.

Speed The ports can operate at either 10 or 100 Mbps. The speeds may be set

manually using the management software or automatically with Auto­Negotiation (IEEE 802.3u), the default setting.

Duplex Mode The twisted pair ports can operate in either half- or full-duplex mode. The

duplex mode determines the manner in which a port transmits data. A port
set to half-duplex can either transmit or receive data at one time, while a
port operating in full-duplex can transmit and receive data at the same
time. The best network performance is achieved with the full-duplex
setting, but not all network equipment is designed to support that duplex
mode.

The duplex modes, like port speeds, may be set manually using the
management software or automatically with Auto-Negotiation (IEEE

802.3u), the default setting.

Wiring

Configuration

The speed and duplex mode settings of a port may be set independently
of each other. For example, a port may be configured such that its speed
is set manually while its duplex mode is established through Auto­Negotiation.

A switch port that is connected to a network device that does not
support Auto-Negotiation and has a fixed duplex mode of full-duplex
should not set its duplex mode with Auto-Negotiation. A duplex­mode mismatch in which a switch port and a network device operate
at different duplex modes, may occur. The duplex modes of switch
ports that are connected to network devices that do not support
Auto-Negotiation should be set manually through the management
software.

The wiring configuration of a port can be MDI or MDI-X. The wiring
configurations of a switch port and a network device connected with
straight-through twisted pair cabling have to be opposite, such that one
device is using MDI and the other MDI-X. For instance, a switch port has
to be set to MDI-X if it is connected to a network device set to MDI.

You may set the wiring configurations of the ports manually or let the
switch configure them automatically with auto-MDI/MDI-X (IEEE 802.3ab­compliant). This feature enables the switch to negotiate with network
devices to establish the proper settings, so that the ports on the devices
are using different wiring configurations.

10/100/1000Base-T Twisted Pair Ports

The switches have two 10/100/1000Base-T ports. These ports are paired
with SFP slots to form combo ports.

Speed The ports can operate at 10, 100, or 1000 Mbps. The speeds may be set

manually using the management software or automatically with Auto­Negotiation (IEEE 802.3u), the default setting.

The ports must be set to Auto-Negotiation to function at 1000 Mbps.
They are not compatible with devices that are not IEEE 802.3u
compliant.

Duplex Mode The twisted pair ports can operate in either half- or full-duplex mode. The

duplex modes, like port speeds, may be set manually using the
management software or automatically with Auto-Negotiation (IEEE

802.3u), the default setting.

Wiring

Configuration

The speed and duplex mode settings of a port may be set independently
of each other. For example, a port may be configured such that its speed
is set manually while its duplex mode is established through Auto­Negotiation.

A switch port that is connected to a network device that does not
support Auto-Negotiation and has a fixed duplex mode of full-duplex
should not set its duplex mode with Auto-Negotiation. A duplex­mode mismatch in which a switch port and a network device operate
at different duplex modes, may occur. The duplex modes of switch
ports that are connected to network devices that do not support
Auto-Negotiation should be set manually through the management
software.

The wiring configuration of a port operating at 10 or 100 Mbps can be MDI
or MDI-X. The wiring configurations of a switch port and a network device
connected with straight-through twisted pair cabling have to be opposite,
such that one device is using MDI and the other MDI-X. For instance, a
switch port has to be set to MDI-X if it is connected to a network device set
to MDI.

You may set the wiring configurations of the ports manually or let the
switch configure them automatically with auto-MDI/MDI-X (IEEE 802.3ab­compliant). This feature enables the switch to automatically negotiate with
network devices to establish the proper settings.

SFP Slots

FS970M Series Installation Guide

The switches have two slots for 100Mbps 100Base-FX or 1000Mbps
1000Base-SX/LX fiber optic transceivers. The transceivers can be used to
connect the switches to other network devices over large distances, build
a high-speed backbone network between network devices, or connect
high-speed devices, such as servers, to your network.

The switches support a variety of short and long distance, 100 and 1000
Mbps fiber optic SFP modules. For a list of supported SFP modules,
contact your Allied Telesis representative or visit our web site.

The two SFP slots are paired with the two 10/100/1000Base-T ports. The
combo ports are listed in Table 9.

The rules for using the combo ports are listed here:

 Only one port in a combo pair is active at a time.
 The twisted pair port is the default active port.
 The SFP slot becomes active when an SFP transceiver establishes

a link to another network node.

 The twisted pair port of a combo pair remains deactivated so long

as the SFP transceiver has a link to another network device.

 The switch automatically reactivates the twisted pair port if the

companion SFP module loses its network link.

 The twisted pair port and SFP module of a combo port share the

same settings, such as VLAN assignments, access control lists,
and spanning tree.

37

Overview

 Port speed is an exception to the shared settings of the twisted pair

port and SFP slot of a combo port. If you disable Auto-Negotiation
on the twisted pair port and set the speed and duplex mode
manually, the switch reactivates it when an SFP module
establishes a link with an end node.

38

Power Over Ethernet

The AT-FS970M/8PS, AT-FS970M/8PS-E, AT-FS970M/24PS, and
AT-FS970M/48PS Switches feature Power over Ethernet (PoE) on the 10/
100Base-TX ports. PoE is used to supply power to network devices over
the same twisted pair cables that carry the network traffic.

The main advantage of PoE is that it makes it easier to install a network.
The placement of network devices is often limited by whether there are
power sources nearby. This often limits equipment placement or requires
the added time and cost of having additional electrical sources installed.
But with PoE, you can install PoE-compatible devices wherever they are
needed without having to worry about whether there are power sources
nearby.

A device that provides PoE to other network devices is referred to as
power sourcing equipment (PSE). The AT-FS970M/8PS,
AT-FS970M/8PS-E, AT-FS970M/24PS, and AT-FS970M/48PS Switches
act as PSE units by adding DC power to the network cable, thus
functioning as a central power source for other network devices.

FS970M Series Installation Guide

Devices that receive their power from a PSE are called powered devices
(PD). Examples include wireless access points, IP telephones, webcams,
and even other Ethernet switches.

The switch automatically determines whether or not a device connected to
a port is a powered device. Ports that are connected to network nodes that
are not powered devices (that is, devices that receive their power from
another power source) function as regular Ethernet ports, without PoE.
The PoE feature remains activated on the ports but no power is delivered
to the devices.

PoE Standards The AT-FS970M/8PS, AT-FS970M/8PS-E, AT-FS970M/24PS, and

AT-FS970M/48PS Switches support these PoE standards:

 PoE (IEEE 802.3af): This standard provides up to 15.4 watts at the

switch port to support powered devices that require up to 12.95
watts.

 PoE+ (IEEE 802.3at): This standard provides up to 30.0 watts at

the switch port to support powered devices that require up to 25.5
watts.

Powered Device

Classes

Powered devices are grouped into the five classes listed in Table 10 on
page 40. The classes are based on the amount of power the devices
require. The switches support all five classes.

39

Overview

Note

0 15.4W 0.44W to 12.95W

2 7.0W 3.84W to 6.49W
3 15.4W 6.49W to 12.95W
4 30.0W 12.95W to 25.5W

PoE+ Class 4 powered devices (IEEE 802.3at) with a power range
of 12.95 to 25.5 watts must use LLDP to identify their power
requirements to the switch. Non-compliant PoE+ powered devices
that do not support LLDP will be limited to 802.3af (15.4 watts)
power levels.

Power Budget The AT-FS970M/8PS, AT-FS970M/8PS-E and AT-FS970M/24LPS

Switches have a power budget of 185 watts. The AT-FS970M/24PS and
AT-FS970M/48PS Switches have a power budget of 370 watts. These are
the maximum amounts of power the switches can provide at one time to
the powered devices.

The AT-FS970M/24PS and AT-FS970M/48PS Switches have two power
supplies. Each power supply is responsible for providing 185 watts, or
half, of the power budget. Both power supplies must be connected to AC
power sources for the switch to provide the full 370 watts. The power
budget is reduced to 185 watts if only one power supply is connected to a
power source.

The power requirements of the PoE devices determine the maximum
number of devices the switch can support at one time. So long as the total
power requirements of the powered devices is less than the power budget
of the switch, the switch can supply power to all of the devices. If the total
power requirements exceed the power budget, the switch denies p ower to
one or more ports using a mechanism referred to as port prioritization.

To determine whether the power requirements of the PoE devices you
plan to connect to the switch exceed its power budget, refer to their
documentation for their power requirements and add the requirements
together. The switch should be able to power all of the devices
simultaneously as long as the total is below its power budget. If the total
exceeds the available power budget, you should consider reducing the
number of PoE devices so that all of the devices receive power.

40

FS970M Series Installation Guide

Otherwise, the switch powers a subset of the devices, based on port
prioritization.

The switch can handle different power requirements on different ports.
This enables you to connect different classes of PoE equipment to the
ports on the switch.

Port

Prioritization

If the power requirements of the powered devices exceed the switch’s
power budget, the switch denies power to some ports based on a system
called port prioritization. You may use this mechanism to ensure that
powered devices critical to the operations of your network are given
preferential treatment by the switch in the distribution of power should the
demands of the devices exceed the available capacity.

There are three priority levels:

 Critical
 High
 Low

Ports set to the Critical level, the highest priority level, are guaranteed
power before any of the ports assigned to the other two priority levels.
Ports assigned to the other priority levels receive power only if all the
Critical ports are receiving power. Ports that are connected to your most
critical powered devices should be assigned to this level. If there is not
enough power to support all the ports set to the Critical priority level, power
is provided to the ports based on port number, in ascending order.

The High level is the second highest level. Ports set to this level receive
power only if all the ports set to the Critical level are already receiving
power. If there is not enough power to support all of the ports set to the
High priority level, power is provided to the ports based on port n umber, in
ascending order.

The lowest priority level is Low. This is the default setting. Ports set to this
level only receive power if all of the ports assigned to the other two levels
are already receiving power. As with the other levels, if there is not enough
power to support all of the ports set to the Low priority level, power is
provided to the ports based on port number, in ascending order.

Power allocation is dynamic. Ports supplying power to powered devices
may cease power transmission if the switch’s power budget is at maximum
usage and new powered devices, connected to ports with higher priorities,
become active.

You can use port prioritization on dual power supply PoE switches to
protect your important networking devices from loss of power should one
of the power supplies fail or lose power. By limiting the power
requirements of the critical devices connected to a switch to less than 185
watts, the PoE power provided by a single power supply, a switch will have

41

Overview

sufficient power to support the critical devices even if it has only one
functional power supply.

Wiring

Implementation

The IEEE 802.3af standard defines two methods by which a PSE, such as
the switch, can transmit DC power over twisted pair cables to PDs. These
methods, known as modes A and B, identify the wire strands the switch
should use when sending DC power to a PD.

Twisted pair cabling typically consists of eight strands. With 10Base-T and
100Base-TX devices, the strands connected to pins 1, 2, 3, and 6 on the
RJ-45 connectors carry the network traffic while strands connected to pins
4, 5, 7, and 8 are unused. With 1000Base-T devices, all eight strands are
used to carry network data.

It takes four strands to deliver DC power to a PD. With Mode A, the power
is delivered on pins 1, 2, 3, and 6. These are the same pins in 10Base-T
and 100Base-TX devices that carry the network data. With mode B, the
power is provided over the spare strands.

The ports on the AT-FS970M/24PS and AT-FS970M/48PS Switches
deliver the power using pins 4, 5, 7, and 8, which corresponds to mode B
in the IEEE 802.3af standard.

Powered devices that comply with the IEEE 802.3af standard are required
to support both power delivery methods. Legacy devices that do not
comply with the standard will work with the switch if they are powered on
pins 4, 5, 7, and 8.

eco-friendly Button

Note

FS970M Series Installation Guide

You may turn off the port LEDs to conserve electricity when you are not
monitoring the switch. The LEDs may be toggled with the eco-friendly
button on the front panel of the switch or the ECOFRIENDLY LED and NO
ECOFRIENDLY LED commands in the Global Configuration mode of the
command line interface.

Toggling the LEDs on and off does not interfere with the network
operations of the device. The System LED is always on.

When checking or troubleshooting the network connections to the
ports on the switch, you should always check to be sure that the
LEDs are on by either pressing the eco-friendly button or issuing the
ECOFRIENDLY LED and NO ECOFRIENDLY LED commands in
the Global Configuration mode of the command line interface.

Console Port

Note

FS970M Series Installation Guide

The Console port is used to configure the features and parameter settings
of the switch. This type of management uses serial RS-232 and is
commonly referred to as local or out-of-band management because it is
not conducted over your network. To perform local management, you must
be at the location of the switch and must use the management cable
included with the switch.

To establish a local management session with the switch, you connect a
terminal or a personal computer with a terminal emulation program to the
Console port, which has an RJ-45 style (8P8C) connector, using the
provided management cable. The cable which has RJ-45 RJ-style (8P8C)
and DB-9 (D-sub 9-pin) connectors.

The Console port is set to the following specifications:

 Default baud rate: 9600 bps (Range is 9600 to 115200 bps)
 Data bits: 8
 Parity: None
 Stop bits: 1
 Flow control: None

These settings are for a DEC VT100 or ANSI terminal, or an
equivalent terminal emulation program.

Power Supplies

The following switches have one power supply:

 AT-FS970M/8
 AT-FS970M/8PS
 AT-FS970M/8PS-E
 AT-FS970M/24C
 AT-FS970M/24LPS
 AT-FS970M/48

These switches have two power supplies:

 AT-FS970M/16F8-LC
 AT-FS970M/16F8-SC
 AT-FS970M/24F
 AT-FS970M/24PS
 AT-FS970M/48PS

The power supplies have separate AC connectors on the back panels.
The power supplies are not field-replaceable.

The power supplies in the dual power supply switches operate in active
and standby states for all hardware operations, except for PoE. One
power supply is active, powering the switching functions of the device,
while the second power supply operates in a redundant state. The switch
automatically activates the redundant power supply if the active power
supply loses power or fails. The change over is instantaneous, making it
transparent to the network users. Power redundancy is available only
when both AC connectors on the switch are connected to power sources.

For PoE, however, the power supplies in the AT-FS970M/24PS and
AT-FS970M/48PS Switches operate in a load-sharing manner, with each
power supply providing 185 watts, half the total PoE budget of the switch.
The maximum 370 watts power budget of PoE is only available when both
power supplies are connected to power sources.

Refer to “Technical Specifications” on page 97 for the input voltage range.

Choosing a Site for the Switch

Observe these requirements when planning the installation of the switch.

 If you plan to install the switch in an equipment rack, the rack

should be safely secured so 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 plan to install the switch on a table, the table should be level

and stable.

 The power outlet should be located near the switch and be easily

accessible.

 The site should allow for easy access to the ports on the front of

the switch, so that you can easily connect and disconnect cables,
and view the port LEDs.

 The site should allow for adequate air flow around the unit and

through the cooling vents on the front and rear panels. (The
ventilation direction in units that have a cooling fan is from front to
back, with the fan on the back panel drawing the air out of the unit.)

 The site should not expose the switch to moisture or water.
 The site should be a dust-free environment.
 The site should include dedicated power circuits or power

conditioners to supply reliable electrical power to the network
devices.

 The site should not be a wiring or utility box because the switch will

overheat and fail from inadequate airflow.

Switches should not be stacked on top of one another on a table or
desktop because that could present a personal safety hazard if you
need to move or replace switches.

71

Cabling the Networking Ports

Cabling the Twisted Pair and Fiber Optic Ports

This section contains the guidelines to cabling the twisted pair and fiber
optic ports.

Twisted Pair

Ports

Here are the guidelines to cabling the 10/100Base-TX and 10/100/
1000Base-T twisted pair ports:

 The cable specifications for the 10/100Base-TX and 10/100/

1000Base-T twisted pair ports are listed in Table 7 on page 34 and
Table 8 on page 36, respectively.

 The connectors on the cables should fit snugly into the ports, and

the tabs should lock the connectors into place.

 The default setting for the wiring configurations of the ports is auto-

MDI/MDI-X. The default setting is appropriate for switch ports that
are connected to 10/100Base-TX network devices that also
support auto-MDI/MDI-X.

 The default auto-MDI/MDI-X setting is not appropriate for switch

ports that are connected to 10/100Base-TX network devices that
do not support auto-MDI/MDI-X and have a fixed wiring
configuration. For switch ports connected to those types of network
devices, you should disable auto-MDI/MDI-X and set the wiring
configurations manually.

 The appropriate MDI/MDI-X setting for a switch port connected to a

10/100Base-TX network device with a fixed wiring configuration
depends on the setting of the network device and whether the
switch and network device are connected with straight-through or
crossover cable. If you are using straight-through twisted pair
cable, the wiring configurations of a port on the switch and a port
on a network device must be opposite each other, such that one
port uses MDI and the other MDI-X. For example, if a network
device has a fixed wiring configuration of MDI, you must disable
auto-MDI/MDI-X on the corresponding switch port and manually
set it to MDI-X. If you are using crossover twisted pair cable, the
wiring configurations of a port on the switch and a port on a
network device must be the same.

72

 The default speed setting for the ports is Auto-Negotiation. This

setting is appropriate for ports connected to network devices that
also support Auto-Negotiation.

 The default speed setting of Auto-Negotiation is not appropriate for

ports connected to 10/100Base-TX network devices that do not
support Auto-Negotiation and have fixed speeds. For those switch
ports, you should disable Auto-Negotiation and set the port’s
speed manually to match the speeds of the network devices.

FS970M Series Installation Guide

 The 10/100/1000Base-T ports must be set to Auto-Negotiation, the

default setting, to operate at 1000Mbps.

 The default duplex mode setting for the ports is Auto-Negotiation.

This setting is appropriate for ports connected to network devices
that also support Auto-Negotiation for duplex modes.

 The default duplex mode setting of Auto-Negotiation is not

appropriate for ports connected to network devices that do not
support Auto-Negotiation and have a fixed duplex mode. You
should disable Auto-Negotiation on those ports and set their duplex
modes manually to avoid the possibility of duplex mode
mismatches. A switch port using Auto-Negotiation defaults to half­duplex if it detects that the end node is not using Auto-Negotiation,
which can result in a mismatch if the end node is operating at a
fixed duplex mode of full-duplex.

Fiber Optic Ports Here are the guidelines to cabling the 100Base-FX fiber optic ports:

 The cable specifications for the 100Base-FX fiber optic ports are

listed in Table 4 on page 27.

General

Guidelines

 Do not remove the dust covers from the fiber optic ports until you

are ready to connect the fiber optic cables. Dust contamination can
adversely affect the operations of the ports.

 The connectors on the cables should fit snugly into the ports, and

the tabs should lock the connectors into place.

These guidelines apply to both the twisted pair and fiber optic ports:

 If the switch will have a static or an LACP port trunk, you should

create the trunk first using the switch’s management software
before connecting the cables of the trunk. Otherwise, a network
loop will result which can adversely affect network performance.

 If your network topology contains a loop where two or more

network devices can communicate with each other over more than
one network path, do not connect the network cables that form the
loop until after you activate one of the spanning tree protocols on
the switch. Data loops can adversely affect network performance.
For background information on the spanning tree protocols, refer to
the FS970M Series AlliedWare Plus Command Line Interface
User’s Guide.

73

Cabling the Networking Ports

Warning

Note

Installing Optional SFP Transceivers

Review the following guidelines before installing optional SFP transceivers
in the switch:

 The SFP slots are part of combo ports, with 10/100/1000Base-T

ports. For operational information, refer to “SFP Slots” on page 37.

 SFP transceivers can be hot-swapped while the switch is powered

on. However, you should always disconnect the fiber optic cable
first before removing a transceiver.

 You should install the transceiver before connecting the fiber optic

cable.

 Fiber optic transceivers are dust sensitive. Always keep the plug in

the optical bores when a fiber optic cable is not installed, or when
you store the transceiver. When you do remove the plug, keep it
for future use.

 Unnecessary removal and insertion of a transceiver can lead to

premature failure.

A transceiver can be damaged by static electricity. Be sure to
observe all standard electrostatic discharge (ESD) precautions,
such as wearing an antistatic wrist strap, to avoid damaging the
device.

The cable specifications of optional SFP transceivers are found in
the installation guides that ship with the devices.

To install an SFP transceiver:

1. Remove the dust plug from a transceiver slot on the switch. Refer to
Figure 28 on page 75.

74

FS970M Series Installation Guide

Starting a Management Session

You may use the following methods and tools to manage FS970M
Switches:

 Local management  Telnet client  Secure shell client  HTTP non-secure and HTTPs secure Web browser  SNMPv1, v2C, v3

FS970M Series Installation Guide

Local

Management

Telnet

Management

Local management uses the Console port on the switch. It is commonly
referred to as out-of-band management because the management
sessions are not conducted over your network. Listed here are the
requirements for local management:

 A terminal or computer with a terminal emulator program
 The management cable included with the switch.

This management method uses the command line interface, which gives
you access to all of the features and parameters on the switch. For
instructions on how to start a local management session, refer to “Starting
a Local Management Session” on page 88.

The switch has a Telnet server. You may use the server to manage the
unit over your network with the Telnet application protocol. Commonly
referred to as in-band management because it is conducted over the
network, this management method has these requirements:

 Your management workstation must have a Telnet client.
 The Telnet server on the switch has to be activated. This is the

server’s default setting.

 The switch must have an IP address. You may use the factory

169.254.1.1 address assigned to the Default VLAN, which contains
all of the ports on the switch. For instructions on how to assign the
switch a different address, refer to the FS970M Series AlliedWare
Plus Command Line Interface User’s Guide.

 You need to assign your management workstation an IP address in

the 169.254.n.n subnet or your workstation must have access to
that subnet through routing devices.

Telnet management uses the Command Line Interface, giving you access
to all of the features and parameter settings on the switch. For inst ructions
on how to start a Telnet management session on the switch, refer to
“Starting a Telnet Management Session” on page 90.

85

Powering On the Switch

Telnet management sessions are not secure and are vulnerable to
snooping because the packets exchanged between the switch and your
workstation are sent in plain text. The security of the switch may be
jeopardized if an intruder captures the packet containing your username
and password. For secure remote management, use the secure shell
protocol.

Secure Shell

Management

Secure shell management is similar to Telnet management in that you
may use it, together with the Command Line Interface, to manage all of
the features and functions of the switch, from a workstation on your
network. The difference is that this management method encrypts the
packets exchanged by your computer and the switch to protect your
management sessions.

Here are the requirements for SSH management:

 Your management workstation must have an SSH client.
 The SSH server on the switch has to be activated. The server’s

default setting is disabled.

 You have to create an encryption key on the switch.
 The switch must have an IP address. You may use the factory

169.254.1.1 address assigned to the Default VLAN.

 You need to assign your management workstation an IP address

in the 169.254.n.n subnet or your workstation must have access to
that subnet through routing devices.

For instructions on how to configure the switch for SSH management,
refer to the FS970M Series AlliedWare Plus Command Line Interface
User’s Guide.

Web Browser

Management

86

Yet another way to remotely manage the switch is with a web browser. A
special web browser interface, featuring both non-secure (HTTP) and
secure (HTTPS) operation, lets you monitor and configure many of the
switch’s features from a series of windows. The interface, however, may
only be used to configure a subset of the features. To configure those
features the web browser interface does not support, you have to use the
command line interface from another management method.

Here are the requirements for non-secure HTTP web browser
management:

 Your management workstation must have a web browser.
 The web browser server on the switch has to be activated. This is

the default setting in the default BOOT.CFG and QSTART.CFG
files.

 The switch must have an IP address. You may use the factory

169.254.1.1 address assigned to the Default VLAN.

FS970M Series Installation Guide

 You need to assign your management workstation an IP address in

the 169.254.n.n subnet or your workstation must have access to
that subnet through routing devices.

Refer to the FS970M Series AlliedWare Plus Command Line Interface
User’s Guide for instructions on how to configure the switch for secure
HTTPS web browser management.

SNMP Refer to the FS970M Series AlliedWare Plus Command Line Interface

User’s Guide for instructions on how to configure the switch for SNMP

management. The switch does not have any default SNMP community
strings.

87

Powering On the Switch

Note

Starting a Local Management Session

This procedure requires a terminal or a terminal emulator program and the
management cable that comes with the switch. Perform the following
procedure to start a local management session on the switch:

1. Connect the RJ-45 connector on the management cable to the
Console port on the front panel of the switch.

Figure 37. Connecting the Management Cable to the Console Port

2. Connect the other end of the cable to an RS-232 port on a terminal or
PC with a terminal emulator program.

3. Configure the terminal or terminal emulator program as follows:

 Baud rate: 9600 bps (The baud rate of the Console Port is

adjustable from 1200 to 115200 bps. The default is 9600 bps.)

 Data bits: 8
 Parity: None
 Stop bits: 1
 Flow control: None

The port settings are for a DEC VT100 or ANSI terminal, or an
equivalent terminal emulator program.

4. Press Enter.
You are prompted for a user name and password.

88

FS970M Series Installation Guide

5. Enter the user name and password to log on the switch. If this is the
initial management session of the switch, enter “manager” as the user
name “friend” as the password. The user name and password are case
sensitive.

The local management session starts when the AlliedWare Plus™
command line prompt, shown in Figure 38. is displayed.

Figure 38. AlliedWare Plus Command Line Prompt

For information on the command line interface, refer to the FS970M
Series AlliedWare Plus Command Line Interface User’s Guide.

Powering On the Switch

Note

Starting a Telnet Management Session

To perform this procedure, you must have Telnet client software on your
computer. This procedure assumes that you will be connecting your
computer to a twisted pair port on the switch. But you may use a fiber optic
port. To start a Telnet management session on the switch using the
factory IP address, perform the following procedure:

1. Assign your computer the IP address 169.254.n.n with the subnet
mask 255.255.0.0. The variable n can be from 1 to 255. You may not
use the switch’s IP address 169.254.1.1. Refer to your computer’s
documentation for instructions on how to set the address.

If your computer is running a DHCP client, it automatically defaults
to an 169.254.n.n address if it does not receive a response from a
DHCP server. To have the DHCP client assign the address,
disconnect your computer from your network, power it on, wait for
the DHCP client to generate the IP address 169.254.n.n, and then
connect the computer to your new FS970M Series switch.

2. Connect a twisted pair cable to one of the networking ports on the
switch. You may connect the cable to any of the ports, except the
Console port.

3. Connect the other end of the cable to the Ethernet port on your
computer.

4. Start the Telnet client on your computer and specify the switch’s IP
address, 169.254.1.1.

You are prompted for a user name and password.

5. Enter the user name and password to log on the switch. If this is the
initial management session of the switch, enter “manager” as the user
name “friend” as the password. The user name and password are
case sensitive.

The local management session starts when the AlliedWare Plus™
command line prompt, shown in Figure 38 on page 89. is displayed.
For information on the command line interface, refer to the FS970M
Series AlliedWare Plus Command Line Interface User’s Guide.

Specifying Ports in the Command Line Interface

port1.0

.n

Slot ID

Port Number

Stack ID

The command line interface of the Local, Telnet, and SSH management
methods gives you the ability to configure all the features and parameters
on the switch. Many of the commands have the PORT parameter, which
you use to identify the networking ports on the switch. This parameter has
the following format:

Figure 39. PORT Parameter in the Command Line Interface

FS970M Series Installation Guide

The first number is the switch’s stack ID number. This number is always 1
for FS970M Series switches because they are not stacking switches.

The slot ID value, which is used to specify slot numbers in a multi-module
chassis, also does not apply to the FS970M Series switches and is always

0.
The third value is a port number on the switch. You may specify only one

port number in a PORT parameter, but you may specify more than one
PORT parameter in many of the commands where the parameter is
supported.

Here is an example of the PORT parameter. It uses the INTERFACE
command to enter the Port Interface mode for ports 15 and 17:

awplus> enable
awplus# configure terminal
awplus(config)# interface port1.0.15,port1.0.17

You can also specify port ranges. This example displays the port settings
for ports 21 to 23:

awplus# show interface port1.0.21-port1.0.23

Note that you must include the prefix “port1.0.” in the last number of a
range.

You can also combine individual ports and port ranges in the same
command, as illustrated in these commands, which enter the Port
Interface mode for ports 5 to 11 and ports 16 and 18:

91

Powering On the Switch

awplus> enable
awplus# configure terminal

Note

Troubleshooting

This chapter contains suggestions on how to troubleshoot the switch if a
problem occurs.

For further assistance, please contact Allied Telesis Technical
Support at www.alliedtelesis.com/support.

Problem 1: All the LEDs on the switch are off.
Solutions: Try the following:

 Press the eco-friendly button on the front panel to see if the switch

is operating in the low power mode with the LEDs off. You can also
toggle the LEDs off and on with the ECOFRIENDLY LED and NO
ECOFRIENDLY LED commands in the Global Configuration mode
of the command line interface.

 Verify that the power cord is securely connected to the power

source and the AC connector on the back panel of the switch.

 Verify that the power outlet has power by connecting another

device to it.

 Try connecting the unit to another power source.
 Try a different power cord.
 Verify that the voltage from the power source is within the required

levels for your region.

Problem 3: A twisted pair port on the switch is connected to a network
device but the port’s LINK/ACT LED is off.

Solutions: The port is unable to establish a link to a network device. Try
the following:

 Verify that the cable is securely connected to the ports on the

switch and network device.

 Verify that the port is connected to the correct twisted pair cable.
 Verify that the network device connected to the twisted pair port is

powered on and is operating properly.

93

Troubleshooting

Note

 Try connecting another network device to the twisted pair port with

a different cable. If the twisted pair port is able to establish a link,
then the problem is with the cable or the other network device.

 Verify that the twisted pair cable does not exceed 100 meters (328

feet).

 Verify that you are using the appropriate category of twisted pair

cable. The cable types are listed in Table 7 on page 34 for the 10/
100Base-TX ports and Table 8 on page 36 for the 10/100/
1000Base-T ports.

A 1000Base connection may require five to ten seconds to est ablish
a link.

Problem 4: The LINK/ACT LED for an SFP transceiver is off.
Solutions: The fiber optic port on the transceiver is unable to establish a

link to a network device. Try the following:

 Check that the SFP module is fully inserted in the slot.
 Verify that the remote network device connected to the fiber optic

port is powered on and operating properly.

 Verify that the fiber optic cable is securely connected to the ports

on the SFP module and remote network device.

 Verify that the operating specifications of the fiber optic ports on

the SFP transceiver and the remote network device are
compatible.

 Verify that the correct type of fiber optic cabling is being used.
 Verify that the port is connected to the correct fiber optic cable.
 Try connecting another network device to the fiber optic port using

a different cable. If the port is able to establish a link, then the
problem is with the cable or network device.

 Use the switch’s management software to verify that the port is

enabled.

 If the remote network device is a managed device, use its

management firmware to determine whether its port is enabled.

 Test the attenuation of both directions on the fiber optic cable with

a fiber optic tester to determine whether the optical signal is too
weak (sensitivity) or too strong (maximum input power).

94

FS970M Series Installation Guide

Problem 5: Network performance between a twisted pair port on the
switch and a network device is slow.

Solution: There might be a duplex mode mismatch between the port and
the network device. This occurs when a twisted pair port using Auto­Negotiation is connected to a device with a fixed duplex mode of full
duplex. If this is the cause of the problem, adjust the duplex mode of the
port on the network device or switch so that both ports are using the same
duplex mode.

Problem 6: The switch functions intermittently.
Solutions: Check the system hardware status through the management

software:

 Use the SHOW SYSTEM ENVIRONMENT command in the

Privileged Exec mode to verify that the input voltage from the
power source to the switch is stable and within the approved
operating range. The unit will shutdown if the input voltage
fluctuates above or below the approved operating range.

 For switches that have a ventilation fan, use the SHOW SYSTEM

ENVIRONMENT command in the Privileged Exec mode to verify
that it is operating correctly.

 Verify that the location of the switch provides adequate airflow. The

unit will shutdown if it is in danger of overheating.
