10/100/1000Base-T Twisted Pair Ports
The switches have 24 10/100/1000Base-T 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
and 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 mode of a port, like port speed, 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 should not use Auto-Negotiation to set its duplex mode
if it is connected to a network device that does not support AutoNegotiation for 10 or 100 Mbps operation and has a fixed duplex
mode of full-duplex. Otherwise, a duplex-mode mismatch may occur
in which a switch port and a network device operate at different
duplex modes. 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 their proper settings.
21
Page 22
Chapter 1: Overview
The MDI and MDI-X settings do not apply when ports are operating at
1000 Mbps.
Maximum
The ports have a maximum operating distance of 100 meters (328 feet).

Power Over Ethernet
The AT-IX5-28GPX switch features Power over Ethernet (PoE) on the 10/
100/1000Base-T 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 can make it easier to install a
network. The selection of a location for a network device is often limited by
whether there is a power source 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-IX5-28GPX switch acts as a
PSE unit by adding DC power to the network cable, thus functioning as a
central power source for other network devices.
IX5-28GPX 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-IX5-28GPX switch supports 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.

Power Budget The AT-IX5-28GPX switch has a power budget of 720 watts when two
power supply modules are installed. This is the maximum amount of power
the switch can provide at one time to the powered devices.
Two power supplies must be installed for the switch to provide the full 720
watts. Each power supply is responsible for providing 360 watts, or half, of
the power budget. The power budget is reduced to 360 watts if only one
power supply is installed.
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 the devices. But if the total
power requirements exceed the power budget, the switch denies power 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
25
Page 26
Chapter 1: Overview
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.
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 number, in
ascending order.
26
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.
Page 27
IX5-28GPX Installation Guide
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. If you limit the power requirements
of the critical devices connected to a switch to less than 360 watts, the
PoE power provided by a single power supply module, a switch will have
sufficient power to support the critical devices even if it has only one
functional power supply module.
Wiring
Implementation
The IEEE 802.3af standard defines two methods for the delivery of DC
power over twisted pair cable by a PSE, such as the switch, to PDs. These
methods, known as modes A and B, identify the wires within the cable that
carry the DC power from the PSE to a PD.
Twisted pair cabling typically consists of eight wires. With 10Base-T and
100Base-TX devices, the wires connected to pins 1, 2, 3, and 6 on the RJ45 connectors carry the network traffic while the wires connected to pins 4,
5, 7, and 8 are unused. With 1000Base-T devices, all eight wires are used
to carry network data.
It takes four wires 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 wires.
The ports on the AT-IX5-28GPX switch deliver the power using pins 1, 2,
3, and 6, which corresponds to mode A 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 1, 2, 3, and 6.

Chapter 1: Overview
Note
SFP+ Slots
The switches have four SFP+ slots that support the following types of SFP
1000Mbps and SFP+ 10Gbps transceivers:
1000Base-SX/LX SFP transceivers
Single-port BiDi 1000Base-LX SFP transceivers
1000Base-ZX SFP transceivers
10Gbps, 10GBase-SR/LR fiber optic transceivers
10Gbps AT-SP10TW direct connect twinax cables with SFP+
transceiver-style connectors
You may use the transceivers to connect switches to other network
devices over large distances, build high-speed backbone networks
between network devices, or connect high-speed devices, such as
servers, to your network.
The switches support a variety of short and long distance SFP and SFP+
modules. For a list of supported SFP modules, contact your Allied Telesis
representative or visit our web site.
SFP+ slots 27 and 28 are initially configured as stacking slots for the
VCStack feature. If you intend to use the switch as a stand-alone
unit, you must disable the VCStack feature before using the slots
with standard SFP or SFP+ transceivers. See Chapter 5,
“Configuring the Switch for Stand-alone Operations” on page 77 for
instructions.
28
Page 29
Stacking SFP+ Slots
Note
Two of the four SFP+ slots on the front panel of the switch can be used
with stacking transceivers to create a VCStack of up to four AT-IX528GPX switches. The switches of a VCStack act as a single virtual unit.
They synchronize their actions so that switching operations, like spanning
tree protocols, virtual LANs, and static port trunks, span across all the
units and ports. The two main advantages of stacks are:
The slots for the stacking transceivers are SFP+ slots 27 and 28.
IX5-28GPX Installation Guide
You can manage multiple units simultaneously, which can simplify
network management.
You have more flexibility in how you configure some of the
features. For instance, a static port trunk on a stand-alone switch
has to consist of ports from the same switch. In contrast, a static
trunk on a stack may consist of ports from different switches in the
same stack.
If you use the switch as a stand-alone device, you can use the slots
with regular SFP and SFP+ transceivers by disabling the VCStack
feature. See Chapter 5, “Configuring the Switch for Stand-alone
Operations” on page 77 for instructions.

Note
eco-friendly Button
You may turn off the port LEDs to conserve electricity when you are not
monitoring the switch. The LEDs are 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. The switch is said to be operating in a low power
mode when the LEDs are turned off.
Operating the switch in the low power mode with the LEDs turned off does
not interfere with the network operations of the device.
The Switch ID LED is always on, but it displays different information
depending on whether the LEDs are on or off. When the LEDs are on, the
ID LED displays the switches ID number. When the switch is operating in
the low power mode with the LEDs off, the LED indicates whether the
switch is a stand-alone unit or the master or member switch of a VCStack,
as detailed in Figure 8 on page 35.
Before 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 command line interface.

Console Port
Note
IX5-28GPX Installation Guide
The Console port is used to establish a management session with the
switch to configure its features and parameter settings. 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, 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 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.

Chapter 2: Virtual Chassis Stacking
Overview
Virtual Chassis Stacking (VCStack) allows you to connect up to four ATIX5-28GPX switches to form a virtual switch in which the devices function
as a single networking unit. The benefits of VCStack are:
Simplifies management - You can manage the devices of the stack
as a single unit, rather than individually. Your local and remote
management sessions automatically give you management
access to all the devices.
Reduces IP addresses - A stack requires only one IP address for
remote management access, thereby reducing the number of IP
addresses you have to assign to network devices, The one
address gives you management access to all the units.
Adds feature flexibility and resiliency - A stack gives you more
flexibility in how you can configure some features. For instance,
you can create port aggregators of ports from different switches in
the stack, rather than from only one switch. If you distribute the
ports of an aggregator across two or more switches in a stack, you
increase its resiliency because the aggregator will continue to
function, though at a reduced bandwidth, if one of the switches
stops functioning.
Reduces protocol requirements - Creating a stack might eliminate
your need to configure some protocols, such as the Virtual Router
Redundancy Protocol and Spanning Tree Protocol.

Stacking Slots
Note
IX5-28GPX Installation Guide
The AT-IX5-28GPX switches come with two stacking slots. The slots are
the last two SFP+ slots on the switches and are labeled S1/27 and S2/28.
The slots have two functions. You may use them with the VCStack feature
to build a stack of switches or, by disabling the VCStack feature, you may
use them with regular SFP or SFP+ transceivers as additional networking
slots.
The names of the slots depend on the status of the VCStack feature on the
switch. The management software refers to the slots as “S1” and “S2.”
when the VCStack feature is enabled and the slots are used with the
special stacking transceivers to create a stack.
When you disable the VCStack feature to use the slots with regular SFP or
SFP+ transceivers on a stand-alone switch, the slots are referred to as
slots 27 and 28. See Chapter 5, “Configuring the Switch for Stand-alone
Operations” on page 57 for instructions for disabling VCStack.
When VCStack is enabled on the switch, the stacking slots only
work with the stacking transceivers in Table 7 on page 42. If you
install regular SFP or SFP+ transceivers in the stacking slots when
stacking is activated, the management software disables them and
enters an error message in the buffered log.

connected to other AT-StackOP/0.3 and AT-StackOP/9.0
transceivers. The transceivers do not work with other types of

Stacking Port Topologies
The switches of a stack are connected with the S1 and S2 ports and the
stacking transceivers shown in Figure 10 on page 42.
There are two wiring configurations. The first topology is called the linear
topology. In this topology the switches are connected with a single
pathway. A stacking transceiver in one switch is connected to a stacking
transceiver in the next switch, which is connected to the next switch, and
so on. The connections must crossover to different stacking slots on the
switches. The stacking transceiver in the S1 slot in one switch must
connect to the stacking transceiver in the S2 slot in the next switch.
Figure 11 is an example of a stack of two switches in the linear topology.
The transceiver in the S1 slot on the top switch is connected to the
transceiver in the S2 slot on the bottom switch.
44
Figure 11. Stack of Two Switches in the Linear Topology
The stack will not function if the connections to the S1 and S2 slots
do not crossover on the switches. The switches will not form a stack
and instead operate as stand-alone devices.

The stack in Figure 12 on page 45 has four switches in the linear topology.
Figure 12. Stack of Four Switches in the Linear Topology
The second topology is called the ring topology. It is similar to the linear
topology, except that the unused stacking ports on the end switches of the
stack are connected to form a physical loop. This topology is more resilient
than the linear topology because there are two pathways through the
stack. If one pathway fails, the switches can maintain communications
through the alternate pathway. The example in Figure 13 on page 46
shows a ring topology of two switches.

Figure 14. Stack of Four Switches in the Ring Topology
The topologies are the same in terms of network speed and performance.
However, the ring topology is the recommended wiring configuration
because of the secondary path through the stacking ports. The two
pathways protect the switches of the stack against the loss of
communications due to a failure of a stacking port, cable, or switch.
The examples in the previous figures showed the twinax AT-StackXS/1.0
stacking transceiver. But the same rules apply to the fiber optic ATStackOP/0.3 and AT-StackOP/9.0 stacking transceivers. A fiber optic
transceiver in the S1 slot must crossover to a fiber optic transceiver in the
S2 slot of another switch.

Chapter 2: Virtual Chassis Stacking
Master and Member Switches
The stack has one master switch. The functions of the master switch
include:
Coordinating and monitoring stack operations.
Verifying that the switches are using the same version of
management software. It automatically downloads its management
software over the stacking cables to switches with different
software versions.
Verifying that the switches have different ID numbers. It
automatically assigns new ID numbers to resolve situations where
two or more switches have the same ID number.
Verifying that the stacking transceivers that connect the switches
together are cabled correctly.
The other switches are called member switches. There can be up to three
member switches in addition to the master switch. A member switch can
automatically transition to the master role if the current master switch is
removed from the stack or powered off. This ensures continued operations
of the stack even if the master switch stops operating.
Selection of the
Master Switch
The devices compare the following numbers to choose the master switch
when the stack is reset or powered on:
Stack priority numbers
MAC addresses
The stack priority number is an adjustable value of 0 to 255, where the
lower the number, the higher the priority. Typically, the switch with the
lowest priority number (highest priority) becomes the master switch of a
stack. The default priority value is 128.
If the switches have the same priority values, the selection of the master
switch is based on their MAC addresses. As with the priority value, the
lower the MAC address, the higher the priority. The switch with the lowest
MAC address becomes the master switch.
If you power on the stack for the first time without adjusting the priority
values, the master switch is selected based on the MAC addresses if the
units are powered on simultaneously. If you power on the switches one at
a time, the master switch is the first switch to be powered on. This is
explained in Chapter 8, “Powering On the Stack” on page 101.
After the stack is established and operating, you may, if you choose,
change the priority settings on the individual units and so control which
switch will be the master switch after subsequent power cycles and resets.

IX5-28GPX Installation Guide
Caution
ID Numbers Each switch must be assigned an ID number. The range is 1 to 4 and the
default is 1. The ID numbers are displayed on the ID LEDs on the front
panels of the units. You may assign the numbers yourself or you can let
the master switch assign the numbers automatically, as explained in
Chapter 8, “Powering On the Stack” on page 101.
You use the ID numbers to identify the individual ports and switches when
you configure the devices with the commands in the management
software. For further information, refer to “Specifying Ports in the
Command Line Interface” on page 50.
The ID numbers are also used to identify the parameter settings that are
stored in the configuration file. When the stack is reset or power cycled,
the ID numbers identify the devices to which the parameter settings
belong.
You should not change the ID numbers of the switches after you
have started to configure the parameter settings. Otherwise, the
parameter settings might be applied to the wrong devices when you
reset or power cycle the stack.
The switches do not use the ID numbers to select the master switch. The
selection of the master switch is typically based on the priority numbers
and MAC addresses, as previously explained.

Specifying Ports in the Command Line Interface
The command line interface in the management software on the switch
has a parameter that you use to specify the individual ports. The
parameter is the PORT parameter and Figure 15 shows its format.
Figure 15. PORT Parameter in the Command Line Interface
The first number is the switch’s ID number. The ID numbers of switches in
a stack are displayed on their ID LEDs. You can also view the ID numbers
with the SHOW STACK command in the command line interface.
The module ID value is used with multi-module products. This value does
not apply to the x510 Series switches and should always be 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 on the
switch with ID 2:
awplus> enable
awplus# configure terminal
awplus(config)# interface port2.0.15,port2.0.17
For instructions on the command line interface and the PORT parameter,
refer to the Software Reference: AlliedWare Plus Operating System for
IX5-28GPX Switches.

Warning
Choosing a Site for the Switches
Observe these requirements when planning the installation of the switches
of a stack.
If you plan to install the switches in an equipment rack, check to be
sure that the rack is 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 switches on a table, check to be sure that
the table is level and stable.
The power outlet should be located near the switches and be
easily accessible.
The site should allow for easy access to the ports on the front of
the switches, so that you can easily connect and disconnect
cables, and view the port LEDs.
The site should allow for adequate air flow around the units and
through the cooling vents on the front and rear panels. (The
ventilation direction 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 switches 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.
Do not install the switches in a wiring or utility box because they
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.
56
Page 57
Planning a Stack
x510 Series Installation Guide for Virtual Chassis Stacking
Here are the guidelines to planning a stack:
A stack can have up to four AT-IX5-28GPX switches.
Any of the switches in the stack can be the master switch.
Switches connected with AT-StackXS/1.0 stacking cables should
be installed in a standard 19-inch equipment rack and not more
than one meter apart, the length of the stacking cable. The end
switches cannot be more than one meter apart if you want to
create the ring topology, shown in Figure 13 on page 46 and Figure
14 on page 47.
You may use the AT-StackOP/0.3 and AT-StackOP/9.0
transceivers to build stacks of switches that are up to 300 meters
and 9 kilometers apart, respectively.
The wiring topology of the stack may be either linear or ring. Both
topologies offer the same in terms of speed, but the ring topology
adds wiring redundancy.
You can use combinations of AT-StackXS/1.0, AT-StackOP/0.3,
and AT-StackOP/9.0 cables when the individual switches of the
stack are at various distances from each other.
The switches do not need any additional software for stacking.
However, they do need stacking transceivers.
You may not install a networking device, such as a media
converter or Ethernet switch, between two fiber optic stacking
transceivers.
All switches must have the same licenses of optional features. If
you install an optional feature on one switch, you must install it on
all switches before assembling the stack.
The AT-StackOP/9.0 transceiver has a maximum operating
distance of 9 kilometers and requires 9/125 µm single-mode fiber
optic cable. The operating specifications of the transceiver are
listed in Table 17 on page 129.
Table 8 on page 58 lists the maximum distances of the AT-
StackOP/0.3 transceiver. The operating specifications of the
transceiver are listed in Table 16 on page 128.

Configuring the Switch for Stand-alone Operations
Disabling
VCStack
After the switch has initialized its management software, examine the
switch ID LED on the front panel and do one of the following:
If the LED is displaying “0,” the installation procedure is complete.
The switch is now ready for network operations as a stand-alone
unit. Refer to the Software Reference: AlliedWare Plus Operating
System for IX5-28GPX Switches for instructions on how to
configure the operating parameters.
If the LED is displaying a number other than “0,” perform the
following procedures to disable the VCStack feature.
You have to reset the switch as part of the procedure to disabling
the VCStack feature. Some network traffic may be lost if the device
is already connected to a live network.
The initial management session of the switch must be from the
Console port.
To disable the VCStack feature to use the switch as a stand-alone unit,
perform the following procedure:
Disabling the VCStack feature requires resetting the switch. If the
switch is already connected to a live network, some network traffic
may be lost.
1. Unless you have already done so, start a local management session
as described in “Starting a Local Management Session” on page 72.
2. When prompted, enter a 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 and “friend” as the password. The user
name and password are case sensitive.
The local management session starts when the User Exec mode
prompt, shown in Figure 34. is displayed.

3. Enter the SHOW STACK command to display the status of the
VCStack feature. Figure 35 is an example of the command.
Figure 35. SHOW STACK Command
4. Review the following items:
If the Operational Status is “Stacking Hardware Disabled,” the
VCStack feature is already disabled on the switch and the SFP+
stacking slots may be used with regular SFP or SFP+ transceivers.
If the Operational Status is “Standalone Unit,” as shown in Figure
35 on page 79, the VCStack feature is active on the unit. You must
disable it by performing the steps in the rest of this procedure
before you can use the SFP+ stacking slots with regular SFP or
SFP+ transceivers. The reason the status says “standalone” is
because the switch considers itself a stack of one switch.
5. Move to the Global Configuration mode by entering the ENABLE and
CONFIGURE TERMINAL commands, as shown in Figure 36.
Figure 36. Moving to the Global Configuration Mode
6. To. disable the VCStack feature on the switch, enter the NO STACK
ENABLE command, which has this format:

10. Enter the REBOOT command to reboot the switch.
11. At the confirmation prompt, type “Y” for yes.
12. Wait for the switch to initialize its management software and
afterwards examine the Switch ID LED. The switch is ready for normal
network operations as a stand-alone unit when its ID number is “0.”
Refer to the Software Reference: AlliedWare Plus Operating System
for IX5-28GPX Switches for instructions on how to configure the
operating parameters. If the number is not “0,” repeat this procedure.

Confirming the
Status of the
VCStack Feature
Another way to confirm that VCStack is disabled on the switch is by
displaying the status of the last two SFP+ slots on the switch. These are
slots 27 and 28. If VCStack is disabled, you should be able to display the
status of the slots even when they do not have transceivers. If VCStack is
not disabled, the switch displays a message that it cannot find the slots. To
view the status of the stacking slots, perform this procedure:
1. Start a management session on the switch. For directions, refer to
“Configuring the Switch for Stand-alone Operations” on page 78.
2. Log on to the switch. The default user name is “manager” and the
password is “friend”.
3. From either the User Exec mode or Privileged Exec mode, enter the
SHOW INTERFACE command to display the status of one of the last
two SFP+ slots on the switch. For example, enter this command to
view the status of slot 27:
show interface port1.0.27
If VCStack is disabled, the switch displays the status of the designated
slot. An example is shown in Figure 40 on page 81.

Specifying Ports in the Command Line Interface for Stand-alone Switches
The command line interface in the management software on the switch
has a parameter that you use to specify the individual ports. The
parameter is the PORT parameter and Figure 42 shows its format.
Figure 42. PORT Parameter in the Command Line Interface
The first number is the switch’s ID number. The ID number for stand-alone
switches is not the value 0 displayed on the Switch ID LEDs. Rather, it is 1.
Be sure to enter 1, not 0, as the ID number in the PORT parameter when
configuring ports on stand-alone switches.
The module ID value is used with multi-module products. This value does
not apply to the x510 Series switches and should always be 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 commands where the parameter is supported.
Here is an example of the PORT parameter on a stand-alone switch. 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
For instructions on the command line interface and the PORT parameter,
refer to the Software Reference: AlliedWare Plus Operating System for
IX5-28GPX Switches.

Page 86
Chapter 6: Verifying the Status of VCStack and Activating VCStack
Verifying the Status of VCStack
Before you install the stacking transceivers to build the stack, you should
first test the switches to determine whether the VCStack feature is
enabled or disabled, and enable it on any units where it is disabled. On
new switches, the feature should be activated because that is the default
setting. But on switches that were previously used as stand-alone units,
the feature is probably disabled and needs to be enabled.
Testing the status of VCStack is simple. You power on a switch and watch
the ID LED. If it displays a number from 1 to 4, VCStack is already
enabled. If the LED displays the number 0, the feature is disabled and
needs to be enabled.
To test the status of VCStack, perform the following procedure:
1. Power on one of the switches.
Connect a power cord to one of the power connectors on the back
panel and to an AC power source. The unit has two power connectors,
but you do not need to connect both power cords for this procedure.
2. Wait one minute for the switch to initialize its management software.
3. View the ID LED and do one of the following:
If the ID LED is displaying a number from 1 to 4 (1 is the default),
VCStack is already enabled on the switch. Power off the unit by
disconnecting the power cord and test the remaining switches in
the same manner. After testing all the switches, be sure the
switches are powered off and go to Chapter 7, “Cabling the
Stacking Ports” on page 91.
If the ID LED is displaying “0,” the VCStack feature is disabled on
the switch. You must enable it by performing the procedure in
“Activating the VCStack Feature” on page 87.

Perform the following procedure to activate the VCStack feature on
switches that display the number “0” on their ID LEDs in the previous
procedure. The tasks follow on from “Monitoring the Initialization
Processes” on page 73.

Activating
VCStack
To activate VCStack, perform the following procedure:
1. Unless you have already done so, start a local management session
as described in “Starting a Local Management Session” on page 72.
2. When prompted, enter a 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 and “friend” as the password. The user name and
password are case sensitive.
The local management session starts when the User Exec mode
prompt, shown in Figure 43. is displayed.
