The ports can operate at either 10 or 100 Mbps. The speeds may be set
manually using the management software or automatically with AutoNegotiation (IEEE 802.3u), the default setting.
The twisted pair ports can operate in either half- or full-duplex mode. The
duplex mode determines the manner in which a port transmits data. A port
set to half-duplex can either transmit or receive data at one time, while a
port operating in full-duplex can transmit and receive data at the same
time. The best network performance is achieved with the full-duplex
setting, but not all network equipment is designed to support that duplex
mode.
The duplex modes, like port speeds, may be set manually using the
management software or automatically with Auto-Negotiation (IEEE
802.3u), the default setting.
The switch allows you to set the speed and duplex mode settings of a port
independently of each other. For example, you might set the speed
manually and the duplex mode with Auto-Negotiation.
Note
A switch port that is connected to a network device that does not
support Auto-Negotiation and has a fixed duplex mode of full-duplex
should not set its duplex mode with Auto-Negotiation. A duplexmode mismatch in which a switch port and network device operate
at different duplex modes, may occur. The duplex modes of switch
ports that are connected to network devices that do not support
Auto-Negotiation should be set manually with the management
software.
Wiring
Configuration
The wiring configuration of a port can be MDI or MDI-X. The wiring
configurations of a switch port and a network device connected with
straight-through twisted pair cabling have to be opposite, such that one
device is using MDI and the other MDI-X. For instance, a switch port has
to be set to MDI-X if it is connected to a network device set to MDI.
You may set the wiring configurations of the ports manually or let the
switch configure them automatically with auto-MDI/MDI-X (IEEE 802.3abcompliant). This feature enables the switch to negotiate with network
devices to establish the proper settings, so that the ports on the devices
are using different wiring configurations.

Power Over Ethernet
The AT-x310-26FP and AT-x310-50FP Switches feature Power over
Ethernet (PoE) on the 10/100Base-TX ports. PoE is used to supply power
to network devices over the same twisted pair cables that carry the
network traffic.
Note
PoE is not available on the two 10/10/10000Base-T ports.
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-x310-26FP and AT-x310-50FP
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
The AT-x310-26FP and AT-x310-50FP 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.
27
Chapter 1: Overview
Powered Device
Classes
Powered devices are grouped into the five classes listed in Table 3. The
classes are based on the amount of power the devices require. The
switches support all five classes.

Requirements
The cable requirements for ports operating at 10 or 100Mbps are given in
Table 1 on page 24.
Power Budget
The AT-x310-26FP and AT-x310-50FP 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 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 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.
28
x310 Series Installation Guide for Stand-alone Switches
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
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.
29
Chapter 1: Overview
Wiring
Implementation
The IEEE 802.3af standard defines two methods for delivering DC power
over twisted pair cable by a PSE, such as a switch, to PDs. These
methods, known as Alternatives A and B, identify which of the wires within
the cables are to carry the DC power from the switches to the PDs.
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 Alternative 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
Alternative B, the power is provided over 4, 5, 7, and 8, which are spare
wires.
The ports on the AT-x310-26FP and AT-x310-50FP Switches deliver the
power using pins 4, 5, 7, and 8, which corresponds to Alternative B in the
IEEE 802.3af standard. Therefore, the switches can support PDs that use
Alternative B to receive power.
PDs that comply with the IEEE 802.3af and 802.3at standards are
required to support both Alternative A and B. However, non-standard PDs
and PDs that were manufactured before the completion of the IEEE
802.3af and 802.3at standards and that support only Alternative A will not
work with the switches.

x310 Series Installation Guide for Stand-alone Switches
SFP Slots
The switches have two SFP slots that support the following types of SFP
1000Mbps transceivers:

1000Base-SX/LX SFP transceivers

Single-port BiDi 1000Base-LX SFP transceivers

1000Base-ZX SFP transceivers
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 modules.
For a list of supported SFP modules, contact your Allied Telesis
representative or visit our web site.
Note
The SFP slots and 10/100/1000Base-T ports are paired together to
form combo port pairs. For information, refer to “Combo 10/100/
1000Base-T Ports and SFP Slots” on page 32.
31
Chapter 1: Overview
Combo 10/100/1000Base-T Ports and SFP Slots
The two 10/100/1000Base-T ports and SFP slots are paired together to
form combo port pairs. Each pair contains one 10/100/1000Base-T port
and one SFP slot. The combo port pairs for the switches are listed in
Table 4.

AT-x310-50FT and AT-x310-50FP
The rule to follow when using the combo port pairs is to use only one
device in a pair at a time. For example, if you decide to use twisted pair
port 25R on the AT-x310-26FT or AT-x310-26FP Switch, then you cannot
use SFP slot 25. Or, if you choose to use SFP slot 49 on the AT-x31050FT or AT-x310-50FP Switch, then you cannot use the twisted pair port
49R.
The rules for using the combo port pairs are listed here:
32

You may use either the twisted pair port or SFP slot of a combo
port pair, but not both at the same time.

If you connect both the twisted pair port and SFP slot of a combo
port pair to network devices, the SFP slot takes priority and the
twisted pair port is blocked.

The SFP slot becomes active when the SFP transceiver
establishes a link to a network device.

The twisted pair port and SFP slot of a combo port pair share the
same settings, such as VLAN assignments, access control lists,
and spanning tree.
x310 Series Installation Guide for Stand-alone Switches
Stacking Slots
The S1 and S2 slots on the front panel of the switch are 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 with 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 stacking transceiver is called the AT-StackXS/1.0 transceiver. It has
two SFP transceiver-style connectors and one meter of twinax cable.
Refer to Figure 7.
Figure 7. AT-StackXS/1.0 Stacking Transceiver
Note
This guide explains how to install the devices as stand-alone units.
For instructions on how to install the switches in a stack with Virtual
Chassis Stacking (VCStack), refer to the x310 Series Installation
Guide for VCStack.
Note
The stacking slots may only be used with the stacking transceivers.
They may not be used as regular networking ports.

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 14 on page 42.
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.

Chapter 1: Overview
Console Port
The Console port is used to conduct management sessions 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
Note
These settings are for a DEC VT100 or ANSI terminal, or an
equivalent terminal emulation program.

Cabling the Networking Ports
This chapter contains the following procedures:

“Cabling the Twisted Pair Ports” on page 86

“Installing SFP Transceivers” on page 88
85
Chapter 5: Cabling the Networking Ports
Cabling the Twisted Pair Ports
Here are the guidelines to cabling the 10/100Base-TX and 10/100/
1000Base-T twisted pair ports:
86

The cable specifications for the 10/100Base-TX and 10/100/
1000Base-T twisted pair ports are listed in Table 1 on page 24 and
Table 2 on page 26, respectively.

The connectors on the cables should fit snugly into the ports, and
the tabs should lock the connectors into place.

The default setting for the wiring configurations of the ports is 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
x310 Series Installation Guide for Stand-alone Switches
that also support Auto-Negotiation for duplex modes.

The default duplex mode setting of Auto-Negotiation is not
appropriate for ports connected to network devices that do not
support Auto-Negotiation and have a fixed duplex mode. You
should disable Auto-Negotiation on those ports and set their duplex
modes manually to avoid the possibility of duplex mode
mismatches. A switch port using Auto-Negotiation defaults to halfduplex if it detects that the end node is not using Auto-Negotiation.
This 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.
87
Chapter 5: Cabling the Networking Ports
Installing SFP Transceivers
This section contains guidelines and procedures for installing SFP
transceivers. The installation procedures are listed here:
Here are general installation guidelines for SFP transceivers:

SFP transceivers are hot-swappable. You may install them while
the chassis is powered on.

The SFP slots are paired with the 10/100/1000Base-T ports to
form combo pair ports. You may use either the SFP slot or twisted
pair port of a combo pair, but not both at the same time. For more
information, refer to “Combo 10/100/1000Base-T Ports and SFP
Slots” on page 32.

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.

Do not install SFP transceivers in the S1 and S2 slots. These slots
are for stacking transceivers and are not used when the switch is
used as a stand-alone unit.
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.

Chapter 5: Cabling the Networking Ports
Note
If you are ready to attach the fiber optic cable to the transceiver,
continue with the next step. Otherwise, repeat steps 1 to 4 to install
another SFP transceiver in the switch.
5. Remove the dust cover from the transceiver, as shown in Figure 42.
Figure 42. Removing the Dust Cover from an SFP Transceiver
6. Verify the position of the handle on the SFP transceiver. If the
transceiver is in a top slot, the handle should be in the upright position,
as shown in Figure 43. If the transceiver is in a bottom slot, the handle
should be in the down position.

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 x310 Series Switches,
AlliedWare Plus Operating System, for instructions on how to
configure the operating parameters.

If the LED is not displaying “0” (for example, if is displaying the
default number “1”), 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

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 53. is displayed.

If the Operational Status is “Stacking Hardware Disabled,” the
VCStack feature is already disabled on the switch. The switch is
ready for operations as a stand-alone switch in your network. No
further installation steps are required.
x310 Series Installation Guide for Stand-alone Switches

If the Operational Status is “Standalone Unit,” as shown in Figure
54 on page 102, 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.

x310 Series Installation Guide for Stand-alone Switches
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 59 shows its format.
port1.0.n
Stack ID
Module ID
Port Number
Figure 59. 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 x310 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 x310 Series Switches, AlliedWare Plus
Operating System.

Chapter 7
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.
107
Chapter 7: 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 2 on page 26 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 transceiver is off.
Solutions: The fiber optic port on the transceiver is unable to establish a
link to a network device. Try the following:
108

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 module and to the port on the remote network device.

Check that the transceiver is fully inserted in the slot.

Check to be sure that the transceiver is not installed in slot S1 or
S2 in the switch. These slots are for AT-Stack transceivers only.

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.

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).
x310 Series Installation Guide for Stand-alone Switches
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 5 on
page 36.
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.

The input voltage on the power supply is outside the normal
operating range.

The internal temperature of the switch has exceeded the normal
operating range and the switch may shut down.
Contact your Allied Telesis sales representative for assistance.
Problem 8: The AT-x310-26FP or AT-3510-50FP Switch is not providing
power to a PoE device.
Solutions: Try the following:

Review the PD’s documentation to confirm that the device supports
Alternative B of the IEEE 802.3at standard. Alternative B 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 Alternative B, the power
109
Chapter 7: Troubleshooting
is carried on pins 4, 5, 7, and 8 on the RJ-45 port, the same pins
that carry the network traffic. The other mode, Alternative A,
defines pins 1, 2, 3, and 6 as the power carriers. The AT-x31026FP and AT-3510-50FP Switches do not support Alternative A.
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 Alternative A will not work
with the switches.
110

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 1 on page 24.

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.
