Chapter 1: Overview
Introduction
The x600 Series Switches are managed Gigabit Ethernet switches that act
as standalone units. There are four Basic Layer 3 switches in the series:
x600-24Ts Switch
x600-24Ts/XP Switch
x600-48Ts Switch
x600-48Ts/XP Switch
The x600-24Ts and the x600-24Ts/XP switches both have 24
10/100/1000Base-T ports. The x600-48Ts and the x600-48Ts/XP
switches both have 44 10/100/1000 Base-T ports.
All four switches have four SFP transceiver slots, a Secure Digital (SD)
card slot, a console port, and a redundant power supply connector. In
addition, the x600-24Ts/XP and the x600-48Ts/XP switches have two XFP
transceiver slots.
On the back of all the switches there is an AC power connector, an RPS
connector, and an expansion slot. You can connect the RPS connector to
the AT-RPS3204 Redundant Power Supply. The x600 switches are
shipped with a blank expansion slot with the exception of the The
x600-48Ts/XP switch which is shipped with an AT-LBM (Loop Back)
module installed in the expansion slot.
The AlliedWare Plus
Operating System Software runs on all the x600
switches.
For more detailed information about the switches, including illustrations,
see “Switch Descriptions” on page 19.

10/100/1000Base-T Twisted Pair Ports
This section describes the twisted pair 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 89.
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 twisted pair 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 twisted pair ports are IEEE 802.3u-compliant and AutoNegotiate the duplex mode setting.
Operating System Software.
You can disable Auto-Negotiation on one or all of the switch ports so that
you can set the duplex mode manually through the AlliedWare Plus
Operating System Software.
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 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 will also disable
Auto-MDI/MDIX and the port’s wiring configuration defaults to the
MDI-X 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).
23
Chapter 1: Overview
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
have 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 have 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 have a
frequency range that extends to 100 MHz.
Auto-MDI/
MDI-X
The twisted pair 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 allows you to connect any network device to a port on
the switch using a straight-through twisted pair cable.
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 Refer to Table 12 on page 89 for the port pinouts when a twisted pair port
operates at 10 or 100 Mbps in the MDI configuration and Table 13 on
page 89 for the MDI-X configuration. For port pinouts when a twisted pair
port operates at 1000 Mbps, refer to Table 14 on page 90.

SFP Transceiver Slots
Note
All of the x600 Series switches feature slots for four optional Gigabit
Ethernet SFP transceivers that interconnect network devices over large
distances using fiber optic cable. SFP transceivers are also available with
a copper cable interface allowing a host device designed primarily for
optical fiber communications to also communicate over unshielded twisted
pair networking cable. Figure 5 illustrates an SFP transceiver.

XFP Transceiver Slots
The x600-24Ts/XP and the x600-48Ts/XP Switches have two slots for
optional XFP 10 Gigabit Ethernet transceivers to connect high speed, 10
gigabit devices to the switch or create high speed backbone networks
between switches.

Redundant Twisted Pair Ports
Four of the twisted pair ports on the x600-24-Ts and x600-24-Ts/XP
switches are paired with SFP slots. The twisted pair 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 1.
Table 1. Twisted Pair Ports Matched with SFP Slots

x600-24Ts/XP
21R with SFP slot 21
22R with SFP slot 22
23R with SFP slot 23
24R with SFP slot 24
Follow these guidelines when using these ports and slots:
Only one port in a pair can be active at a time. It can be either the
twisted pair port or the corresponding SFP module.
The twisted pair port is the active port when its SFP slot is empty, or
when the SFP module is installed but has not established a link to the
end node.
The twisted pair port automatically changes to the redundant status
mode when the SFP module establishes a link with the end node.
The twisted pair port automatically transitions back to the active status
when the link is lost on the SFP module.
In nearly all cases, the twisted pair port and the 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 the twisted pair port and set the speed and duplex
mode manually, the speed reverts to Auto-Negotiation when the SFP
module establishes a link with the end node.

12. The unit can provide power to the switch in the event that the switch’s
internal power supply fails.
The AT-RPS3204 Redundant Power Supply module features one pre
installed AT-PWR3202 Power Supply and three empty slots for additional
power supplies. Each power supply can support one x600 switch. When
fully populated with AT-PWR3202 Power Supplies, the AT-RPS3204 unit
can support up to four x600 switches simultaneously.
The AT-RPS3204 Redundant Power Supply module is hot swappable with
the x600 switches. This means that it is safe to connect a powered on ATRPS3204 module 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.

Series switches with a VCS Stacking module installed in each switch. This
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. Figure 14

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 8.

Features of
VCStacking
The Physical
Stack
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 will continue
to function if a single link fails. Degraded performance might occur
however, due to the reduced VCS bandwidth.
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.
A stack - depending on the switch types used - 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.
40
x600 Series Layer 3 Gigabit Ethernet Switches Installation Guide
AT-StackXG 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 15,
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.

A virtual stack using x600 switches can comprise up to 4 stack members
connected in a ring topology. Figure 16 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

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 9,

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
a. The switch will be unaware of further faults within the stack it was previously a
member of.
b. Should this switch then be powered down, all links previously shutdown (as a
result of running the “no stack enable command”) will remain down.
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 17 shows the resiliency link connecting in a ring topology,
whilst Figure 18 shows the resiliency link connecting to its switch ports via
a network hub. In both configurations, the resiliency link connections are

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.

Chapter 2: Virtual Chassis Stacking
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. Figure 19 shows a stacking ATStackXG module. Refer to “AT-StackXG Module Installation” on page 61
to install this module.

Stack Master

Figure 19. VCS Stacking Module
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.
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:
46
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.
x600 Series Layer 3 Gigabit Ethernet Switches Installation Guide
Note
Note
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.
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
management VLAN ID and IP address, use the show stack command
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 20. 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
. Running this command causes the 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.

Stack Member
Failure and
Recovery
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, will be 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 will update to
reflect the change in MAC address via gratuitous ARP.
49
Chapter 2: Virtual Chassis Stacking
VCS Failure
Recovery
If the stack master either fails, or is removed, the other stack members will
decide which of two actions to take.
1. Fallback action.
2. Re-elect a new stack master.
Note that a master fail-over will be slower than a stack member failure,
and will require the restart (reconvergence) of routing protocols such as
RIP.
Table 9, “State Change Table” on page 43 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.
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’ will be 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.
50
x600 Series Layer 3 Gigabit Ethernet Switches Installation Guide
Note
Stack
Maintenance
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 occur when a fault results in stack splitting into two, with one
of the stack members takes on the role of stack master. Where (unknown
to some of the stack members) the master is still active, the result can be
two independently operating stacks. These are termed stubs.
When two stub stacks are reconnected, a dual master situation will be
detected, and the console log will display the message, 'duplicate master'
was detected. This situation results in the re-election of the stack master.
The losing master will return to being a stack member.

AT-StackXG Module Installation
Caution
Overview 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. This
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. Figure 14
shows the VCS Stacking Module (AT-StackXG).

Figure 27. 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.
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.
Support for the AT-StackXG module requires software version 5.3.1 or
later of AlliedWare Plus Operating System Software.

To install the AT-StackXG module, perform the following procedure:
1. Remove the module from the shipping package.
Store the packaging material in a safe location. You must use the
original shipping material if you need to return the unit to Allied
Telesis.
2. Remove the blank panel from the expansion slot on the rear panel of
the switch by loosening the two captive screws on the panel with a
cross-head screwdriver.

Figure 28. 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 29. 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 twisted pair 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 AutoNegotiation, this feature allows you to use a straight-through 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 32.

x600 Layer 3 Gigabit Ethernet Switch Installation Guide
Cabling the Twisted Pair 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 twisted pair 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 Auto-Negotiation
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.

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.
78
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 11 on page 66.
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.
79
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.

Note
Transceiver is Installed but the Status is “Not Present”
If a SFP or XFP transceiver is installed in a transceiver slot but the Uplink
Information menu in the AlliedWare Plus Operating System Software
interface displays “Not Present” for that port, do the following:
Verify that the transceiver is completely inserted in the slot on the front
of the switch.
The uplink status does not reflect whether a fiber optic cable is
connected to the transceiver.
