Chapter 1: Overview
Note
10/100/1000Base-T Ports
This section describes the 10/100/1000Base-T ports on the switches.
Connector Type The ports are 8-pin RJ-45 connectors that use four pins at 10 or 100 Mbps
and all eight pins at 1000 Mbps. For the pin assignments, refer to “RJ-45
Twisted Pair Port Pinouts” on page 104.
Speed A port’s speed can be 10, 100, or 1000 Mbps. The speed can be set
automatically through Auto-Negotiation, the default setting, or manually
with the AlliedWare Plus
Duplex Mode A 10/100/1000Base-T port can operate in either half- or full-duplex mode.
(Full-duplex mode is the only mode available when a port is operating at
1000 Mbps.) The 10/100/1000Base-T ports are IEEE 802.3u-compliant
and Auto-Negotiate the duplex mode setting.
Operating System Software.
You can disable Auto-Negotiation on the switch ports and set the duplex
mode manually through the AlliedWare Plus
In order for a switch port to successfully Auto-Negotiate its duplex
mode with a 10 or 100 Mbps end node, the end node must also be
configured for Auto-Negotiation. Otherwise, a duplex mode
mismatch can occur. A switch port using Auto-Negotiation defaults
to half-duplex if it detects that the end node is not using AutoNegotiation. This results in a mismatch if the end node is operating
at a fixed duplex mode of full-duplex.
To avoid this problem when connecting an end node with a fixed
duplex mode of full-duplex to a switch port, use the AlliedWare Plus
Operating System Software to disable Auto-Negotiation on the port
and set the port speed and duplex mode manually.
Please be aware that disabling Auto-Negotiation also disables
Auto-MDI/MDIX. The port’s wiring configuration defaults to the MDIX setting. This setting can be configured with the AlliedWare Plus
Operating System Software.

Maximum
Distance
The ports have a maximum operating distance of 100 meters (328 feet).
x600 Series Layer 3 Gigabit Ethernet Switches Installation Guide
Cable Type The cabling requirements for a 10/100/1000Base-T port are:
For 10 Mbps operation: Standard TIA/EIA 568-B-compliant Category 3
or better shielded or unshielded cabling with 100 ohm impedance and
a frequency range that extends to 16 MHz.
For 100 Mbps operation: Standard TIA/EIA 568-A-compliant Category
5 or TIA/EIA 568-B-compliant Enhanced Category 5 (Cat 5e) shielded
or unshielded cabling with 100 ohm impedance and a frequency range
that extends to 100 MHz.
For 1000 Mbps operation: Standard TIA/EIA 568-A-compliant
Category 5 or TIA/EIA 568-B-compliant Enhanced Category 5 (Cat 5e)
shielded or unshielded cabling with 100 ohm impedance and a
frequency range that extends to 100 MHz.
Auto-MDI/
MDI-X
The 10/100/1000Base-T ports on the switch are IEEE 802ab-compliant
and feature auto-MDI/MDI-X. This feature, available when a port’s speed
and duplex mode are set through Auto-Negotiation, automatically
configures a switch port to MDI or MDI-X depending on the wiring
configuration of the port on the end node. This feature allows you to use a
straight-through twisted pair cable when connecting any network device to
a port on the switch.
Disabling Auto-Negotiation on a port and setting the speed and duplex
mode manually also disables the auto-MDI/MDI-X feature. A port where
Auto-Negotiation has been disabled defaults to MDI-X. Disabling AutoNegotiation may require manually configuring a port’s MDI/MDI-X setting
or using a crossover cable.
Port Pinouts The port pinout information is listed in Appendix A, Technical
Specifications.
When operating at 10 or 100 Mbps in the MDI configuration, refer to
the specifications in Table 14 on page 104.
When operating at 10 or 100 Mbps in the MDI-X configuration, refer to
the specifications in Table 15 on page 104.
When a 10/100/1000Base-T port operates at 1000 Mbps, refer to the
specifications in Table 16 on page 105.

SFP Transceiver Slots
All of the x600 Series switches feature slots for four optional Gigabit
Ethernet SFP transceivers. These slots support both fiber optic and
copper transceivers. Fiber optic transceivers let you connect the switches
to other network devices over long distances using fiber optic cables.
Copper transceivers allow you to add more twisted pair ports to your x600
Series switch. Figure 6 illustrates an SFP transceiver.

XFP Transceiver Slots
Note
The x600-24Ts/XP and the x600-48Ts/XP Switches have two slots for
optional XFP 10 Gigabit Ethernet transceivers that you can use to connect
high speed, 10 gigabit devices to the switch or to create high speed
backbone networks between switches. Figure 7 shows an example of an

Chapter 1: Overview
Combo Ports
The 10/100/1000Base-T ports 21R to 24R are paired with the four SFP
slots to form four combo ports on the 24 port x600 Series switches. The
10/100/1000Base-T ports are identified with the letter “R” for “Redundant”
as part of their number on the faceplate of the unit. The ports and slots are
listed in Table 2.

x600-24Ts-POE
Port 21R with SFP slot 21
Port 22R with SFP slot 22
Port 23R with SFP slot 23
Port 24R with SFP slot 24
Follow these guidelines when using these ports and slots:
Only one port in a pair, either a 10/100/1000Base-T port or a
corresponding SFP module can be active at a time.
A 10/100/1000Base-T port is the active port when its SFP slot is
empty, or when an SFP module is installed but has not established a
link to an end node.
A 10/100/1000Base-T port automatically changes to the redundant
status mode when an SFP module establishes a link with an end node.
A 10/100/1000Base-T port automatically transitions back to the active
status when the link is lost on an SFP module.
In nearly all cases, a 10/100/1000Base-T port and an SFP module
share the same configuration settings, including port settings, VLAN
assignments, access control lists, and Spanning Tree Protocol
settings.
An exception to the shared settings is port speed. If you disable Auto-
Negotiation on an 10/100/1000Base-T port and set the speed and
duplex mode manually, the speed reverts to Auto-Negotiation when an
SFP module establishes a link with an end node.
30
The PoE power supplied from ports 21R, 22R, 23R and 24R is
unaffected by insertion of an SFP module in to the corresponding SFP
combo port.

Note
Terminal Port
The terminal port is used to establish a local (out-of-band) management
session with the switch. You establish a local management session by
connecting a terminal or a personal computer with a terminal emulation
program to the port.
The terminal port has an RJ-45 style connector. An RJ-45 to RS-232
management cable is supplied with the switch.
The terminal 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
See Table 17 on page 106 for the pin signal definitions on the RJ-45 port.
These settings are for a DEC VT100 or ANSI terminal, or an
equivalent terminal emulation program.
40
Power Over Ethernet
The following discussion applies to the x600-24Ts-POE Gigabit Ethernet
switch only.
The 10/100/1000Base-T ports on the x600-24Ts-POE switch feature
Power over Ethernet (PoE). PoE is a mechanism for supplying power to
network devices over the same twisted pair cables used to carry network
traffic. This feature can simplify network installation and maintenance by
allowing you to use the switch as a central power source for other network
devices.
A device that receives its power over an Ethernet cable is called a
powered device (PD). Examples of such devices can be wireless access
points, IP telephones, web cams, and even other Ethernet switches. A
powered device connected to a port on the switch will receive both
network traffic and power over the same twisted pair cable.
There are several advantages that the PoE feature of the x600-24Ts-POE
switch adds to the installation and maintenance of your network. First,
because the switch acts as the central power source for your powered
devices, adding an uninterruptible power source (UPS) to the switch
increases the protection not just to the switch itself from possible power
source problems but also to all of the powered devices connected to it.
This can increase the reliability of your network by minimizing the impact
to network operations from a power failure.
x600 Series Layer 3 Gigabit Ethernet Switches Installation Guide
PoE can also simplify the installation of your network. A frequent issue in
selecting a location for a network device is whether there is a power
source nearby. This often limits equipment placement or requires the
added cost and time of having additional electrical sources installed. With
PoE, you can install PoE-compatible network equipment wherever they
are needed without having to worry about whether they are near a power
source.
The switch automatically determines whether or not a device connected to
a port is a powered device. A powered device has a signature resistor or
capacitor that the switch can detect over the Ethernet cabling. If the
resistor or capacitor is present, the switch assumes that the device is a
powered device.
Power Budgeting The x600-24Ts-POE Gigabit Ethernet Switch provides a maximum of
15.4 W per port on all 24 ports for a total power consumption of 370 W,
while at the same time furnishing standard 10/100/1000 Mbps Ethernet
functionality.
41
Chapter 1: Overview
Note
The x600-24Ts-POE smart power management functionality supports any
combination of Ethernet ports (1-24) that supply power for IEEE 802.3af
Class 0, 1, 2, or 3 powered devices up to a maximum of 370 watts, as
described in Table 9.
Table 9. IEEE 802.3af Class vs. Power Levels
Maximum Power
Level Output at
the PD
*
Class Usage
Maximum Power
Level Output at
the PSE
0 Default 15.4W 0.44W to 12.95W
1 Optional 4.0W 0.44W to 3.84W
2 Optional 7.0W 3.84W to 6.49W
3 Optional 15.4W 6.49W to 12.95W
*
The Maximum Power Level Output levels reflect the loss introduced by a 100
meter Ethernet cable between the Power Source Equipment (PSE) and the
Power Device (PD).
A port connected to a network node that is not a powered device functions
as a regular Ethernet port, without PoE. The PoE feature remains enabled
on the port but no power is delivered to the device.
The PoE power supplied from ports 21R, 22R, 23R and 24R is
unaffected by insertion of an SFP module in to the corresponding
SFP combo port.
Implementation A standard Ethernet twisted pair cable contains four pairs of strands for a
total of eight strands. When 10/100 Mbps network traffic is present, only
four strands (1, 2, 3, and 6) are required, which leaves four strands in the
cable unused (4, 5, 7, and 8). When 1000 Mbps network traffic is present,
all eight conductors in the cable are required.
The PoE standard, IEEE 802.3af, describes two alternative ways for
delivering power to a powered device (PD) over twisted pair cabling.
Alternative A uses the same strands that carry the 10/100 Mbps
network traffic. Alternative B uses the spare strands for 10/100 Mbps
network traffic. The PoE implementation on the x600-24Ts-POE Gigabit
Ethernet Switch is Alternative A, where power and 10/100 Mbps network
traffic is transmitted over strands 1, 2, 3, and 6.
42
x600 Series Layer 3 Gigabit Ethernet Switches Installation Guide
IEEE 802.3af compliant PD’s typically support both power delivery
methods. So long as a PD conforms with the standard, it should be able to
receive its power from the switch with either a straight or cross-over cable.
The PoE feature on the x600-24Ts-POE Gigabit Ethernet Switch will work
with legacy PD’s as long as the device can be powered on pins 1, 2, 3, and
6. A legacy device is a node that was manufactured before the IEEE
802.3af standard was completed and may not be compliant. If the device
does not conform to the standard, a cross-over cable may be required to
insure that the correct DC polarity is supplied to the device.
43
Chapter 1: Overview
Redundant Power Supplies
The RPS connector on an x600 Series switch rear panel can connect to
an optional Redundant Power Supply module. The RPS connector on the
x600-24Ts, x600-24Ts/XP, x600-48Ts, or x600-48Ts/XP switch can
connect to the optional AT-RPS3204 Redundant Power Supply, shown in
Figure 20. The RPS connector on the x600-24Ts-POE switch connects to
the optional AT-RPS3104 Redundant Power Supply (not shown). Both
RPS units can provide power to their respective switches in the event of a
failure of the switch’s internal power supply.
Both Redundant Power Supplies feature one pre-installed Power Supply
module and three empty slots for additional power supplies. Each power
supply module can support one x600 switch. When fully populated, each
RPS unit can support up to four x600 switches simultaneously.
The power supply modules in each Redundant Power Supply are hot
swappable with the x600 switches. This means that it is safe to connect a
Redundant Power Supply module with its power ON to an x600 switch
(which is also powered on) using a 21-pin D-combo connector cable from
the module into the RPS connector on the x600 switch.
For information about installing each of the Redundant Power Supply
models, consult the documentation shipped with the unit.
The connector pinouts for the AT-RPS3104 redundant power supply are
described in “AT-RPS3104 17-pin Connector Pinouts” on page 106 and

VCS Stacking Module
A Virtual Chassis Stack (VCS) is a group of x600 Layer 3 Gigabit Ethernet
Series switches with a VCS Stacking module installed in each switch. The
VCS Stacking module with its two full-duplex, 12 Gbps stacking ports,
unifies the individual switches into a single, logical unit so that the network
operations of the devices encompass all of the Gigabit Ethernet ports.
This can simplify network management and augment network bandwidth.

Chapter 2: Virtual Chassis Stacking
VCStackTM Introduction
A Virtual Chassis Stack (VCStack) is a group of physically separate
switches that are connected so as to function as a single logical switch. In
order to function as a VCStack, its component switches are connected
using high-speed stacking links.
Switches must be of the same product type to exist within the same stack.
The principles of product / stack compatibility is shown in the Table 10.

Creating a VCStack (or VCS) greatly eases network management,
because you can configure all the stacked devices via a single IP address.
Creating a VCS will often eliminate your need to configure protocols such
as VRRP and Spanning Tree. VCS also enables you to create highly
resilient networks. This resiliency can be applied in several ways.
Within the stack itself, switch interconnection is via two links. The second
link is able to provide an alternative data path, thus the stack continues to
function if a single link fails. Degraded performance might occur however,
due to the reduced VCS bandwidth.

The Physical
Stack
User ports can also be made extremely resilient by utilizing link
aggregation. Aggregated links can span ports, modules, and even
switches within the stack. Creating aggregated links that span
multiple switches within a stack creates an extremely resilient
configuration. Communication will still exist even if a switch and its
aggregated ports fail.
Depending on the switch types used, a stack can comprise from 2 to 4
individual stack members interconnected via high speed stacking links. A
stack always has a primary stack member called the “stack master”, and
can contain up to 3 other stack members.
x600 Series Layer 3 Gigabit Ethernet Switches Installation Guide
VCS Stacking Modules, Cables, and Connections
The stacks are connected via the stacking ports on the VCS Stacking
Modules (AT-StackXG), which are installed in the back of each switch.
The following cables are used to connect the stacking ports of x600 series
switches:
High Speed Stacking Cables (0.5 meter) - StackXG/0.5
High Speed Stacking Cables (1.0 meter) - StackXG/1
This configuration, shown in Figure 23,
uses two switches that are
connected back to back via two high-speed stacking links. Note that
stacking ports labeled 1 must connect to stacking ports labeled 2. In this
configuration the stack can still function using only a single high speed
link.

Ring Configuration
A virtual stack using x600 switches can comprise up to 4 stack members
connected in a ring topology. Figure 24 shows a ring comprising 3 stacked
x600 series switches. Because an alternate path is provided between the
stack members, this topology offers a very resilient configuration
Figure 24. VCS Ring Topology Using x600 Switches
Resiliency Link Stack Resiliency Link
The purpose of the resiliency link is to provide the stack members with
status information that enables them to detect whether the stack master is
still operational after it has suffered either a power-down or software lockup. This enables the other stack members to either operate in the fall-back
mode, or to re-elect a new stack master. The state change table,Table 11,
“State Change Table” on page 53 shows how the stack members respond
to various problems occurring on the master node.
A resiliency link operates using a resiliency link VLAN to which resiliency
link switch ports can become members.

1. The fallback action on a slave is first to run the fallback config script. Where there is no fallback
script, the switch will disable all its switch ports.
2. The stack member assumes the role of stack master. In specific situations, this condition could
result in a stack containing two masters. This would present problems with network management
and the control of links that were previously aggregated.
3. The following situation will apply to a switch that has been removed from the stack by the using the
NO STACK ENABLE command:
— The switch will be unaware of further faults within the stack it of which it was previously a member.
— If this switch is powered cycled, all links previously shutdown will remain down as a result of
running the NO STACK ENABLE command”.
4. If the slave’s ports are still up, this may cause downstream switches with trunked ports to operate incorrectly.

Two resiliency-link configurations that connect to switch ports are shown
below:Figure 25 shows the resiliency link connecting in a ring topology,
whilst Figure 26 shows the resiliency link connecting to its switch ports via
a network hub. In both configurations, the resiliency link connections are
made using the ResiliencyLink VLAN and attaching the switch ports to the
VLAN. For more information on using the resiliency link commands go to
the Software Reference for the x600 Series Switches which can be found
at www.alliedtelesis.com. The specific commands are the STACK
RESILIENCYLINK command on page 86.27 and the SWITCHPORT
RESILIENCYLINK command on page 86.30.

Resilient Stacked
Topology
Where network connectivity uptime is a major criteria, you can use virtual
chassis stacking to create highly reliable network configurations.
Employing link aggregation rather than spanning tree to manage the
parallel paths, enables the bandwidth of both data links to be utilized under
normal conditions, whilst enabling a single data link to operate should its
partner link fail.
55
Chapter 2: Virtual Chassis Stacking
Note
Stack Formation
A virtual chassis stack (VCS) always contains a master plus a number of
stack members. To be part of a stack, a switch must connect to other
potential stack members via dedicated stacking ports on the VCS Stacking
module located in the rear of the switch.
Once the switches have been physically connected to form a stack,
powering all the members on automatically sets off a number of processes
that enable the stack members to detect the presence of the other stack
members and form themselves into a VCS.
The Role of the
Stack Master
In addition to being a member of its VCS stack, the stack master manages
functions such as software version control and distribution, routing
processing, and network management.
Selecting the Stack Master
The stack members are able to automatically select which switch will
become the stack master. This selection is based on two components:
1. The stack member’s priority setting.
2. The stack member’s MAC address.
For both components, the lower the number the higher the priority. To set
the stack priority, run the STACK PRIORITY command. Note that changes
to these settings will not take effect until the next master re-election. To
display these components run the SHOW STACK command.
The master is the switch with the lowest ‘priority setting’, or if no ‘priority
settings’ are configured, the switch with the lowest MAC address will
become the stack master. When a stack member is initially booted, its
priority value defaults to 128. Therefore if all switches retain their defaults,
then the stack master will be determined by MAC address comparison.
The stack also assigns a Stack Member-ID number to each member. This
number provides a unique reference number for switches within the stack;
it plays no part in selecting the stack master. The Stack Member-ID is the
entity used as the first digit of the three component port identifier numbers.
For example, port number 2.0.14 has the Stack Member-ID of 2.
This last point is an important one to remember when using
configuration scripts. You should ensure that you modify your
configuration scripts to match any changes you have made to the
Stack Member-ID assignments.
56
x600 Series Layer 3 Gigabit Ethernet Switches Installation Guide
Note
The ability to independently set both a stack member’s priority and
its ID means that the stack master does not need to have an ID of 1;
although configuration is simplified by arranging for ID 1 to be the
device with the lowest priority value - and thereby forcing it to be the
stack master. If you create a stack using new switches, the following
(simplified) process should ensure that the master member has an
ID of 1.
New switches are shipped with a Stack Member-ID of 1 and a
priority of 128. If four such switches are created as a stack, the
switch with the lowest MAC address will be selected to be the stack
master (because all priority settings are 128). The remaining three
stack member devices will then reboot and automatically be
assigned IDs values of between 2 and 4. The stack master does not
reboot and retains its Stack Member-ID of 1.
You can change the Stack Member-ID by using the STACK RENUMBER
command.
Common Stack Configuration
Once the switches have configured themselves into a VCS stack, they all
share the same configuration information and startup scripts.
Stack Management VLAN
Managing the stack is the same as managing an individual switch. You
can connect to the asynchronous console port of any stack member, or
you can set an IP address on a network VLAN (for example, VLAN1) and
use SSH or Telnet for remote access.
As the switches form themselves into a stack, each switch creates a
common stack management VLAN and a management IP address. Both
the VLAN ID and the IP address are internal entities that are used between
the stacked switches, via the AT-StackXG interfaces, and therefore do not
appear on the user network.
Initially the stack assigns the default VLAN tag ID of 4094 to the
management VLAN, and assigns an IP address from the subnet
192.168.255.0 / 28 to this VLAN as the management IP address. Once the
stack has formed, you can change both these settings. To change the
VLAN ID use the STACK MANAGEMENT VLAN command. To change the
management IP address use the STACK MANAGEMENT SUBNET
command. Note however, that you must keep the 28 bit subnet mask, (/28
or 255.255.255.240). Also note that because the stack’s internal address
mapping tables will register the management VLAN ID and the
management IP address, these must be unique across the stack’s internal
and external network. To view the current settings for the stack

Stack Member Identification
When a switch becomes a member of a VCS Stack it is assigned a Stack
Member-ID. Stack status information is displayed on the STACK LEDs
shown on the switch’s front panel shown in Figure 27. The following LEDs
indicate the switch’s status within the stack.
To observe the Stack Member-ID of the switch, you first run the SHOW
STACK INDICATOR command
MASTER LED (located within the STATUS LED column) to initially turn
off. A flash sequence then appears followed by a pause. The number of
flashes within each sequence is the same as the Stack Member-ID of the
switch. For example, if the switch had the Stack Member-ID 4, then the
MASTER LED would flash 4 times followed by a pause, then 4 times
again. Note that the MSTR LED that is located within the STACK LED
column, does not perform this function.

Running QoS within a VCS stack
In general you can apply the same principles when configuring QoS on a
VCS stack as you would for single switch; however there are a few specific
changes that you will need to make. See the AlliedWare Plus Software
Reference more information on this topic.
Management IP Addresses
A single virtual MAC address, from the current Master, is used as the stack
MAC address. If the stack master fails, the stack MAC address changes to
reflect the new master's MAC address. If the stack MAC address does
change, ARP tables of devices on the network are updated to reflect the
change in MAC address via gratuitous ARP.
59
Chapter 2: Virtual Chassis Stacking
Note
VCS Failure
Recovery
If the stack master fails or is removed, the other stack members decide
which of two actions to take:
1. Fallback action.
2. Re-elect a new stack master.
The master fail-over process will be slower than a stack member
failure, and will require the restart (reconvergence) of routing
protocols such as RIP.
Table 11, “State Change Table” on page 53 shows how the stack (nonmaster) members would respond to various problems occurring on the
stack master stack.
Fallback Action
To initiate this action, the remaining stack members will disable all ports,
then re-enable them using the fallback config file.
In order to provide an efficient alternative configuration, you should create
a fallback config file that reflects the most appropriate working
configuration for the failures that you feel are most likely to occur. One
way to do this is to create a fall back file from your working system, then
edit this file to provide an appropriate backup system configuration. See
STACK FALLBACK-CONFIG command in the AlliedWare Plus Software
Reference.
60
Re-elect New Stack Master
The stack members automatically determine which of them becomes the
new VCS master.
Recombining Separated Stacks
When two separated stack units (stubs) are reconnected, a condition
known as “multiple master” is detected. In this situation, a new VCS
master is elected based upon the lowest Priority ID or (where both
members have the same Priority ID) the lowest MAC address. The 'losing'
master and the other prospective stack members will then reboot and join
the new stack as ordinary stack members.
x600 Series Layer 3 Gigabit Ethernet Switches Installation Guide
Note
Stack
Maintenance
An operational stack configuration may require occasional maintenance
when you need to add, replace or repairing a broken stack stub.
Adding a Stack Member
An unstacked switch can be added to an existing stack (hot swapped in)
with minimal impact on traffic. To do this, power down the new member
switch, then connect its stacking ports and power on the switch. The
switch will boot as a member of the stack.
The existing Stack Member-ID and the device MAC address will
have no effect on the status of the new member switch. The stack
will admit the new device as ordinary stack member and allocate it a
new Stack Member-ID if its ID is one that already exists.
However, for good practice we recommend pre-configuring the new
member with settings that are appropriate for when the new switch
becomes a stack member. This is to avoid unexpected situations
occurring when the stack is rebooted. For example, if the new
member had a priority setting that was lower than 128 and all the
existing stack members were configured with the default; then, when
the stack is rebooted, the new member would be elected as the
stack master.
Replacing a Stack Member
A stack member can be removed from a stack (hot swap out) with minimal
impact on stack traffic. To do this power-down the stack member,
disconnect its AT-StackXG ports. Insert the new stack member, reconnect
the stacking ports and power-up the new stack member.
You can seamlessly swap a stack member switch into the stack to replace
another with the same configuration. This provides a simple way to replace
an out of service switch with minimal impact, and minimal administration
requirement. You should configure the replacement switch with the same
member ID as its replacement prior to its insertion into the stack.
Repairing a Broken Stub
Stack stubs can occur when a stack fault occurs and results in one of the
stack members assuming the role of a stack master while the original
stack master is still active. In this case, some stack members are still
aware of only the original master while others are only aware of the
second master. The result can be two independently operation stacks,
which are termed “stubs”.
When two stub stacks are reconnected, a dual master situation is detected
and the console log will display the message, ‘duplicate master' was
61
Chapter 2: Virtual Chassis Stacking
detected. This situation results in the re-election of one stack master and
the re-integration of the stack into one entity. The losing master will return
to being a stack member in this process.

Figure 34. VC Stacking (AT-StackXG) Module
Preparation Review the following information before installing the AT-StackXG
Stacking Module:
The AT-StackXG Stacking Module is hardware hot-swappable. You
can install or replace the module while the switch is powered on.
If the stacking module is added or replaced in an operating stack,
the stack topology may change and cause the stack to reboot and
interrupt network traffic.
The AT-StackXG module is supported in all x600 series products and
requires software version 5.3.1 or later of AlliedWare Plus Operating
System Software.
Do not install AT-StackXG module until you have read the latest
version of the AW+ Software Release Notes and the x600 Series
product documentation.

Figure 35. Removing the Blank Panel from the Expansion Slot
All X600 Series Layer 3 Switch models are shipped from the factory
with a Blank Panel installed in the rear panel Expansion Slot except
for the x600-48Ts/XP, which is shipped with an AT-LBM (Loop Back)
module instead.
Do not remove the blank panel from the chassis until you are ready
to install a module. An open slot allows dust to enter the unit and
reduces proper airflow and cooling.
3. Align the edges of AT-StackXG module with the guides in the slot and
carefully slide the module into the chassis until it is flush with the rear
panel of the chassis, as shown in Figure 36 on page 74. Light pressure
may be needed to seat the module on the connector on the rear panel
of the chassis.

The auto-MDI/MDI-X feature on the 10/100/1000Base-T ports
automatically configures the MDI/MDI-X setting when a link is
established with an end node. Available when a port is at the default
setting of Auto-Negotiation, this feature allows you to use a straightthrough twisted pair cable when connecting any type of network
device to a port.
Disabling Auto-Negotiation on a port and setting the speed and
duplex mode manually also disables the auto-MDI/MDI-X feature. A
port where Auto-Negotiation has been disabled defaults to MDI-X.
Disabling Auto-Negotiation may require manually configuring a
port’s MDI/MDI-X setting or using a crossover cable.

Installing SFP/XFP Transceivers
Review the following guidelines before installing an optional SFP or XFP
transceiver in a switch:
A transceiver can be hot-swapped; the switch can be powered on
when you install it. However, you should always disconnect the cables
first before removing a transceiver.
You must install the transceiver before you connect the cables to it.
Fiber optic transceivers are dust sensitive. When a fiber optic cable is
not installed, or when you store the transceiver, always keep the plug
in the optical bores. When you do remove the plug, keep it for future
use.
Unnecessary removal and insertion of a transceiver can lead to
premature failure.
Installing an SFP
Transceiver
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.
To install an SFP transceiver in an x600 switch, perform the following
procedure:
1. Remove the dust plug from a transceiver slot on the switch, as shown
in Figure 39.

x600 Layer 3 Gigabit Ethernet Switch Installation Guide
Cabling the 10/100/1000Base-T and Fiber Optic Ports
Observe the following guidelines when connecting a twisted pair or fiber
optic cable to a port on the switch:
The connector on the cable should fit snugly into the port on the
switch. The tab on the connector should lock the connector into place.
Because the 10/100/1000Base-T ports on the switch are auto-MDI/
MDI-X, any type of network device can be connected to a port on the
switch using a straight-through twisted pair cable. If you disable AutoNegotiation on the port, the port defaults to MDI-X.
If your network topology contains a loop where two or more network
devices can communicate with each other over more than one network
path, make sure that your switch is properly configured with the
appropriate protocol(s); i.e., STP, ESPR, LACP, etc. Data loops
without these protocols enabled can adversely affect network
performance.
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 defaults to half-duplex if it detects that the
end node is not using Auto-Negotiation. This can result in a mismatch
if the end node is operating at a fixed duplex mode of full-duplex.
To avoid this problem, disable Auto-Negotiation on a switch port and
set the port’s speed and duplex mode manually if the end node has a
fixed duplex mode of full-duplex.

contact information.
91
Chapter 5: Troubleshooting
Power LED is Off
Check the PWR LED on the front of the switch. If the LED is off, indicating
that the unit is not receiving power, do the following:
Make sure the power cord is securely connected to the power source
and to the AC connector on the rear panel of the switch.
Verify that the power outlet has power by connecting another device
to it.
Connect the unit to another power source.
Use a different power cord.
Check that the voltage from the power source is within the required
levels for your region.
92
Twisted Pair Port Link LED is Off
Note
When a twisted pair port on the switch is connected to a properly operating
end node, the Link LED for the port should be on. If a Link LED is off, do
the following:
A 1000Base-T connection can take from five to ten seconds to
establish a link.
Verify that the end node connected to the port is powered ON and is
operating properly.
Check that the twisted pair cable is securely connected to the port on
the switch and to the port on the end node.
Make sure that the twisted pair cable does not exceed 100m (328 ft).
Verify that you are using the appropriate category of twisted pair cable.
For information, refer to Table 13 on page 78.
x600 Layer 3 Gigabit Ethernet Switch Installation Guide
Determine if a crossover cable is required. Since the twisted pair ports
feature auto MDI/MDI-X, you should be able to use a straight-through
cable regardless of the type of device you connect to a port. However,
if you disable Auto-Negotiation on a port and set a port’s speed and
duplex mode manually, the port defaults to MDI-X. Disabling AutoNegotiation may require manually configuring a port’s MDI/MDI-X
setting or using a crossover cable.
Make sure that the operating parameters of a port on the switch are
compatible with the end node to which the port is connected. This may
require using the switch’s operating system software.
For a switch port to successfully Auto-Negotiate its duplex mode with
an end node, the end node should also be using Auto-Negotiation.
Otherwise, a duplex mode mismatch can occur. A switch port using
Auto-Negotiation defaults to half-duplex if it detects that the end node
is not using Auto-Negotiation. This can result in a mismatch if the end
node is operating at a fixed duplex mode of full-duplex.
To avoid this problem, disable Auto-Negotiation on a switch port and
set the port’s speed and duplex mode manually if the end node has a
fixed duplex mode of full-duplex.
The switch has a bad cable detection feature that enables it to
determine if a twisted pair cable has a electrical short that might cause
a network loop. If the switch detects a bad cable on a port, it does not
establish a link on that port. In this situation, replace the cable.
93
Chapter 5: Troubleshooting
Note
SFP or XFP LED is Off
When a fiber optic port on the switch is connected to a properly operating
end node, the Link LED for the port should be 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 the port on the end node.
If the fiber optic port is on a SFP or XFP transceiver, check that the
transceiver is firmly inserted into the slot on the switch.
Make sure that you are using the appropriate type of fiber optic cable
and that the cable length does not exceed the allowed maximum
distance. For cable specifications for an SFP transceiver, refer to the
installation instructions shipped with the module.
Use a fiber optic tester to test the attenuation on the cable and the
strength of the optical signal. For operating specifications for an SFP
transceiver, refer to the installation instructions shipped with the
module.
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.
Check that the fiber optic ports on the switch and on the end node are
operating at the same speed and duplex mode.
A fiber optic cable contains two separate fiber strands. One strand is
for receiving data and the other is for transmitting data. When you
connect a fiber optic cable to a port, be sure that the receive fiber
connector is connected to the transmit connector on the remote end
node. In addition, check that the transmit fiber connector is connected
to the receive connector on the remote node.
The L/A LED for an SFP transceiver slot may remain ON if you
remove the transceiver when it has a link to an end node without first
disconnecting the fiber optic cable. The L/A LED will change to OFF
the next time an SFP module is installed in the slot. To avoid this,
always disconnect the fiber optic cable before removing a
transceiver.
