10/100/1000Base-T Twisted Pair Ports
The switches have 24 or 48 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.
Note
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.
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.
Note
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.

Wiring
Configuration

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.

Chapter 1: Overview

The MDI and MDI-X settings do not apply when ports are operating at
1000 Mbps.

Maximum
Distance
Cable
Requirements

The ports have a maximum operating distance of 100 meters (328 feet).

The cable requirements of the ports are given in Table 1.
Table 1. Twisted Pair Cable for the 10/100/1000Base-T Ports

Power Over Ethernet
The AT-x510-28GPX and AT-x510-52GPX Switches feature 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-x510-28GPX and AT-x51052GPX Switches act as PSE units by adding DC power to the network
cable, thus functioning as a central power source for other network
devices.
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

Powered Device
Classes

The AT-x510-28GPX and AT-x510-52GPX Switches support these PoE
standards:


PoE (IEEE 802.3af): This standard provides up to 15.4 watts at the
switch port to support powered devices that require up to 12.95
watts.



PoE+ (IEEE 802.3at): This standard provides up to 30.0 watts at
the switch port to support powered devices that require up to 25.5
watts.

Powered devices are grouped into the five classes listed in Table 2 on
page 26. The classes are based on the amount of power the devices
require. The switches support all five classes.

The AT-x510-28GPX and AT-x510-52GPX Switches have a power budget
of 370 watts. This is the maximum amount of power the switches can
provide at one time to the powered devices.
The AT-x510-28GPX and AT-x510-52GPX Switches have two power
supplies. Each power supply is responsible for providing 185 watts, or half,
of the power budget. Both power supplies must be connected to AC power
sources for the switch to provide the full 370 watts. The power budget is
reduced to 185 watts if only one power supply is connected to a power
source.
The power requirements of the PoE devices determine the maximum
number of devices the switch can support at one time. So long as the total
power requirements of the powered devices is less than the power budget
of the switch, the switch can supply power to all 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
documentation for their power requirements and add the requirements
together. The switch should be able to power all of the devices
27

Chapter 1: Overview

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.
The lowest priority level is Low. This is the default setting. Ports set to this
level only receive power if all of the ports assigned to the other two levels
are already receiving power. As with the other levels, if there is not enough
power to support all of the ports set to the Low priority level, power is
provided to the ports based on port number, in ascending order.
Power allocation is dynamic. Ports supplying power to powered devices
may cease power transmission if the switch’s power budget is at
maximum usage and new powered devices, connected to ports with
higher priorities, become active.
You can use port prioritization on dual power supply PoE switches to
protect your important networking devices from loss of power should one
28

x510 Series Installation Guide for Stand-alone Switches

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 185 watts, the
PoE power provided by a single power supply, a switch will have sufficient
power to support the critical devices even if it has only one functional
power supply.

Wiring
Implementation

The IEEE 802.3af standard defines two methods 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-x510-28GPX and AT-x510-52GPX Switches 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

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.
Note
SFP+ slots 27 and 28 on the AT-x510-28GTX and AT-x510-28GPX
Switches and slots 51 and 52 on the AT-x510-52GTX and AT-x51052GPX Switches 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 you can use the
slots with standard SFP or SFP+ transceivers. The configuration
instructions are provided later in this guide, in “Configuring the
Switch for Stand-alone Operations” on page 74.

x510 Series Installation Guide for Stand-alone Switches

Stacking SFP+ Slots
Two of the four SFP+ slots on the front panel of the switch can be used
with special stacking transceivers to create a VCStack of up to four
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:


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.

The slots for the stacking transceivers are SFP+ slots 27 and 28 on the 28port switches and slots 51 and 52 on the 52-port switches.
The stacking transceivers are listed in Table 5.

Chapter 1: Overview

eco-friendly Button
The eco-friendly button on the front panel of the switch is used to toggle
the port LEDs on or off. You might turn off the LEDs to conserve electricity
when you are not monitoring the device. You can also toggle the LEDs
with 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 management software on the switch has a command that blinks the
LEDs so that you can quickly and easily identify a specific unit among the
devices in an equipment rack. It is the FINDME command. The command
works on the switch even if you turned off the LEDs with the eco-friendly
button or NO ECOFRIENDLY LED command.
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 ID number of the switch. When the switch is operating
in the low power mode with the LEDs off, the ID LED indicates whether the
switch is a stand-alone unit or the master or member switch of a VCStack,
as detailed in Figure 12 on page 40.
Note
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 Global Configuration mode of the command line interface.

Power Supplies
The x510 Series switches have two AC power supplies with separate AC
connectors on the back panels. The power supplies, which are not fieldreplaceable, provide a switch with power redundancy and protect against
interruptions to network operations in the event one of the power supplies
loses power or fails. Power redundancy is available only when both AC
connectors on a switch are connected to power sources.
The AT-x510-28GPX and AT-x510-52GPX Switches have a PoE budget
of 370 watts when both power supplies are active and 185 watts when only
one power supply is active. For further information, refer to “Power

Chapter 2: Beginning the Installation

Choosing a Site for the Switch
Observe these requirements when planning the installation of the switch.


If you plan to install the switch in an equipment rack, 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 switch on a table, check to be sure that the
table is level and stable.



The power outlet should be located near the switch and be easily
accessible.



The site should allow for easy access to the ports on the front of
the switch, so that you can easily connect and disconnect cables,
and view the port LEDs.



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



The site should not expose the switch to moisture or water.



The site should be a dust-free environment.



The site should include dedicated power circuits or power
conditioners to supply reliable electrical power to the network
devices.



Do not install the switch in a wiring or utility box because it will
overheat and fail from inadequate airflow.
Warning
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.

Chapter 4

Cabling the Networking Ports

This chapter contains the following procedures:


“Cabling the Twisted Pair Ports” on page 60



“Installing SFP and SFP+ Transceivers” on page 62

Chapter 4: Cabling the Networking Ports

Cabling the Twisted Pair Ports
Here are the guidelines to cabling the 10/100/1000Base-T twisted pair
ports:



The cable specifications for the 10/100/1000Base-T twisted pair
ports are listed in Table 1 on page 24.



The connectors on the cables should fit snugly into the ports, and
the tabs should lock the connectors into place.



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



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



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



The default speed setting for the ports is Auto-Negotiation. This
setting is appropriate for ports connected to network devices that
also support Aut-Negotiation.



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



The 10/100/1000Base-T ports must be set to Auto-Negotiation, the
default setting, to operate at 1000Mbps.



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

x510 Series Installation Guide for Stand-alone Switches



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



Do not attach cables to ports of static or LACP port trunks until
after you have configured the trunks on the switch. Otherwise, the
ports will form network loops that can adversely affect network
performance.

Chapter 4: Cabling the Networking Ports

Installing SFP and SFP+ Transceivers
This section contains guidelines and procedures for installing SFP and
SFP+ transceivers. The installation procedures are listed here:


“Installing SFP Modules in the AT-x510-28GSX Switch” on page 63



“Installing SFP and SFP+ Modules” on page 66

Here are general installation guidelines for SFP and SFP+ transceivers:


SFP and SFP+ transceivers are hot-swappable. You may install
them while the chassis is powered on.



Your Allied Telesis sales representative can provide you with a list
of supported transceivers for the units.



The operational specifications and fiber optic cable requirements
of the transceivers are provided in the documents included with the
devices.



You should install a transceiver before connecting the fiber optic
cable.



Fiber optic transceivers are dust sensitive. Always keep the plug in
the optical bores when a fiber optic cable is not installed, or when
you store the transceiver. When you do remove the plug, keep it
for future use.



Unnecessary removal and insertion of a transceiver can lead to
premature failure.
Warning
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.

Note
SFP+ slots 27 and 28 on the 28-port switches and slots 51 and 52
on the 52-port switches 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 you can use the
slots with standard SFP or SFP+ transceivers. For instructions, refer
to Chapter 5, “Powering On the Switch” on page 69.

Configuring the Switch for Stand-alone Operations
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 for x510 Series Switches,
AlliedWare Plus Operating System, 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 can disable the VCStack feature from a local management session of
the switch using the Console port. To start a local management session,
go to “Starting a Local Management Session,” next.
Caution
You have to reset the switch to disable the VCStack feature. Some
network traffic may be lost if the device is already connected to a live
network.

Note
The initial management session of the switch must be from the
Console port.

Starting a Local
Management
Session

This procedure requires a terminal or a terminal emulator program and
the management cable that comes with the switch. To start a local
management session on the switch, perform the following procedure:
1. Connect the RJ-45 connector on the management cable to the
Console port on the front panel of the switch, as shown in Figure 33 on
page 75.

Disabling
VCStack

To disable the VCStack feature to use the switch as stand-alone unit,
perform the following procedure:
Caution
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. 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.



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.

x510 Series Installation Guide for Stand-alone Switches



If the Operational Status is “Standalone Unit,” as shown in Figure
35 on page 76, 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.

4. Move to the Global Configuration mode by entering the ENABLE and
CONFIGURE TERMINAL commands, as shown in Figure 36.
awplus> enable
awplus# configure terminal
Enter configuration commands, one per line. End with CNTL/Z
awplus(config)#

5. To. disable the VCStack feature on the switch, enter the NO STACK
ENABLE command, which has this format:
no stack id enable
The ID parameter is the ID number of the switch, displayed on the ID
LED. Replace the parameter with whatever number is on the ID LED.
For example, if the ID number of the switch is 1, the default value,
enter the command as follows:
awplus(config)# no stack 1 enable
This confirmation prompt in Figure 37 is displayed.
Warning; This will disable the stacking hardware on member-1.
Are you sure you want to continue? (y/n):

9. Enter the REBOOT command to reboot the switch.
10. At the confirmation prompt, type “Y” for yes.
11. 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 for x510 Series Switches, AlliedWare
Plus Operating System, 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 on the 28-port switches and slots 51 and 52 on the 52-port
switches. 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 74.
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, for the AT-x510-28GTX
Switch, enter this command to view the status of slot 27:
show interface port1.0.27
4. For the AT-x510-52GTX Switch, enter this command to view the status
of slot 51:
show interface port1.0.51
If VCStack is disabled, the switch displays the status of the designated
slot. An example is shown in Figure 40 on page 79.

has a parameter that you use to specify the individual ports. The
parameter is the PORT parameter and Figure 42 shows its format.
port1.0.n
Stack ID
Module ID
Port Number

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 for x510 Series Switches, AlliedWare Plus
Operating System.

Troubleshooting

This chapter contains suggestions on how to troubleshoot the switch if a
problem occurs.
Note
For further assistance, please contact Allied Telesis Technical
Support at www.alliedtelesis.com/support.
Problem 1: The Switch ID LED on the front of the switch is off.
Solutions: The unit is not receiving power. Try the following:


Verify that the power cord is securely connected to the power
source and to the AC connector on the back panel of the switch.



Verify that the power outlet has power by connecting another
device to it.



Try connecting the unit to another power source.



Try a different power cord.



Verify that the voltage from the power source is within the required
levels for your region.

Problem 2: All of the port LEDs are off even though the ports are
connected to active network devices.
Solution: The switch may be operating in the low power mode. To toggle
on the LEDs, press the eco-friendly button on the front panel of the switch.
You may also toggle the LEDs off and on with the ECOFRIENDLY LED
and NO ECOFRIENDLY LED commands in the command line interface.
Problem 3: A twisted pair port on the switch is connected to a network
device but the port’s LINK/ACT LED is off.
Solutions: The port is unable to establish a link to a network device. Try
the following:


Verify that the port is connected to the correct twisted pair cable.
This is to eliminate the possibility that the port is connected to the
wrong network device.



Verify that the network device connected to the twisted pair port is
powered on and is operating properly.
81

Chapter 6: Troubleshooting



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



Verify that the twisted pair cable does not exceed 100 meters (328
feet).



Verify that you are using the appropriate category of twisted pair
cable. The cable types are listed in Table 1 on page 24 for the 10/
100/1000Base-T ports.
Note
A 1000Base connection may require five to ten seconds to establish
a link.

Problem 4: The LINK/ACT LED for an SFP or SFP+ transceiver is off.
Solutions: The fiber optic port on the transceiver is unable to establish a
link to a network device. Try the following:



Verify that the remote network device connected to the fiber optic
port is operating properly.



Verify that the fiber optic cable is securely connected to the port on
the SFP or SFP+ module and to the port on the remote network
device.



Check that the transceiver is fully inserted in the slot.



If you are using SFP+ slots 27 or 28 on the 28-port switches or
slots 51 and 52 on the 52-port switches, check that VCStack is
disabled on the switch. The VCStack feature has to be disabled
before you can use these slots for regular SFP or SFP+
transceivers. For instructions, refer to “Configuring the Switch for
Stand-alone Operations” on page 74



Verify that the operating specifications of the fiber optic ports on
the transceiver and remote network device are compatible.



Verify that the correct type of fiber optic cabling is being used.



Verify that the port is connected to the correct fiber optic cable.
This is to eliminate the possibility that the port is connected to the
wrong remote network device.



Try connecting another network device to the fiber optic port using
a different cable. If the port is able to establish a link, then the
problem is with the cable or with the other network device.



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



If the remote network device is a managed device, use its
management firmware to determine whether its port is enabled.

x510 Series Installation Guide for Stand-alone Switches



Test the attenuation of both directions on the fiber optic cable with
a fiber optic tester to determine whether the optical signal is too
weak (sensitivity) or too strong (maximum input power).

Problem 5: Network performance between a twisted pair port on the
switch and a network device is slow.
Solution: There might be a duplex mode mismatch between the port and
the network device. This can occur when a twisted pair port using AutoNegotiation is connected to a remote device that has a fixed speed of 10
or 100 Mbps and a fixed duplex mode of full duplex. If this is the cause of
the problem, adjust the duplex mode of the port on the network device or
switch so that both ports are using the same duplex mode. You can use
either the LEDs or management software on the switch to determine the
duplex mode settings of the ports. The LEDs are described in Table 6 on
page 34.
Problem 6: The switch functions intermittently.
Solutions: Check the system hardware status through the management
software:


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



Use the SHOW SYSTEM ENVIRONMENT command in the
Privileged Exec mode to verify that the fan is operating correctly.



Verify that the location of the switch allows for adequate airflow.
The unit will shutdown if it is in danger of overheating.

Problem 7: The Switch ID LED on the front of the switch is flashing the
letter “F.”
Solutions: One or more of the following problems has occurred:


A cooling fan has failed.



One of the power supplies has failed.



The input voltage on one or both of the power supplies is outside
the normal operating range.



The internal temperature of the switch has exceeded the normal
operating range and the switch may shut down.

Chapter 6: Troubleshooting

Problem 8: The AT-x510-28GPX or AT-x510-52GPX Switch is not
providing power to a PoE device.
Solutions: Try the following:



Review the PD’s documentation to confirm that the device
supports Mode A of the IEEE 802.3at standard. Mode A is one of
two modes that define the connector pins that deliver the power
from the port on the line card to the PD. In Mode A, the power is
carried on pins 1, 2, 3, and 6 on the RJ-45 port, the same pins that
carry the network traffic. The second mode, Mode B, defines pins
4, 5, 7, and 8 as the power carriers. The AT-x510-28GPX and ATx510-52GPX Switches do not support Mode B. Most powered
devices are designed to accept power by either mode, but some
legacy devices may only support one mode. This can be verified
by reviewing the device’s documentation or data sheet. Legacy
devices that only support Mode B will not work with the switches.



Check that the device’s power requirements do not exceed 30 W.
This can be verified by reviewing the device’s documentation or
data sheet.



Verify that you are using the appropriate category of twisted-pair
cable by referring to Table 3 on page 26.



Use the management software on the switch to determine whether
PoE is enabled on the port. The default setting for PoE is enabled.



Use the management software on the switch to determine whether
the PoE power setting for the port has been reduced to a value
below the power requirements of the device.



Try connecting the device to a different port on the switch.
