Twisted pair ports
Note
AT-x230-10GP, AT-x230-18GP, AT-x230-18GT and AT-x230-28GP Switches Installation Guide
The number of twisted pair ports supported by each x230 Series switch is:
8 ports: AT-x230-10GP
16 ports: AT-x230-18GP and AT-x230-18GT
24 ports: AT-x230-28GP and AT-x230-28GT
All ports are 10BASE-T, 100BASE-TX, and 1000BASE-T compliant. You
can set the port speeds and duplex modes either automatically with IEEE
802.3u Auto-Negotiation or manually with the management software.
The twisted pair ports feature 8-pin RJ45 connectors. For the port pinouts,
“Connectors and port pinouts” on page 82.
see
The ports have a maximum operating distance of 100 m (328 feet).
The ports feature auto-MDI, which automatically configures the ports as
MDI or MDIX. This feature allows you to use straight-through twisted pair
cables regardless of the wiring configurations of the ports on the end
nodes.
Cable
requirements for
non-PoE ports
A switch port connected to an end node that is not using AutoNegotiation should not use Auto-Negotiation to set the speed and
duplex mode, as a duplex mode mismatch may occur. In this case,
disable Auto-Negotiation and set the port’s speed and duplex mode
manually.
Cable requirements for the non-PoE twisted pair ports are in Table 1. .

Power over Ethernet (PoE)
The AT-x230-10GP, AT-x230-18GP and AT-x230-28GP switches feature
Power over Ethernet (PoE) on the 10/1000BASE-T and 100BASE-TX
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 x230 Series 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 PSE are called powered devices
(PD). Examples of PD include wireless access points, IP telephones,
webcams, and even other Ethernet switches.
The switch automatically determines if 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 x230 Series PoE 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.

Power budget The x230 Series PoE switches have the following power budgets:
AT-x230-10GP: 124 watts
AT-x230-18GP: 247 watts
AT-x230-28GP: 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 o
f 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.
27
Page 38
Chapter 1: Overview
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
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.
28
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. If the switch’s power budget is at its
maximum, ports may stop supplying power to powered devices if new
powered devices, connected to ports with higher priorities, become active.

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
RJ- 45 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 x230 Series PoE 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 2: Installation
Selecting a site for the switch
You can install an x230 Series switch on a desktop, in a standard 19-inch
equipment rack, or on a wall.
Observe the following requirements when choosing a site for your switch:
If you plan to install the switch in an equipment rack, verify that the
rack is safely secured and 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 are installing the switch on a table, verify that the table is
level and secure.
If you are installing the switch on a wall, ensure that the wall is
sturdy enough to hold the switch’s weight. You may need to
position the switch so that it can be screwed into the wall’s framing
timber or an equivalent structural element.
The power outlet for the switch should be located near the unit and
should be easily accessible.
The site should provide for easy access to the ports on the front of
the switch. This will make it easier for you to connect and
disconnect cables, as well as view the switch’s LEDs.
Air flow around the unit and through its vents on the side and rear
should not be restricted so that the switch can maintain adequate
cooling.
Do not place objects on top of the switch.
Do not expose the switch to moisture or water.
Ensure that the site is in a dust-free environment.
You should use dedicated power circuits or power conditioners to
supply reliable electrical power to the network devices.

Installing the switch on a table or a desktop
Here are the guidelines to selecting a suitable site for desktop or table
use:
The table should be level and stable and the power outlets 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 and
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.
The rubber feet on the base of the switches should be left on for
table or desktop installation.
If your switch does not already have rubber feet fitted, fit these as follows:
1. Turn the switch over and place it on a table.
2. Remove the rubber feet from the
packaging and screw them firmly
onto the base of the switch, as shown on Figure 22 on page 52:
F
IGURE 22. ATTACHING THE RUBBER FEET TO A SWITCH
3. Turn the switch over again and place it on a flat, secure surface (such
as a desk or table) leaving ample space around the unit for ventilation.
4. Go to “Cabling the switch” on page 62.

Chapter 2: Installation
Cabling the switch
Observe the following guidelines when connecting twisted pair and fiber
optic cables to the ports on the switch:
The connector on the cable should fit snugly into the port on the
switch. The tab on the connector should lock the connector into
place.
Because the twisted pair ports have auto-MDI/MDIX, you may use
straight-through twisted pair cable to connect any type of network
device to the switch.
If your network topology contains a loop where two or more
network devices can communicate with each other over more than
one network path, do not connect the network cables that form the
loop until after you activate a spanning tree protocol on the switch.
Data loops can adversely affect network performance.
If you are creating a port trunk, do not connect the cables of the
trunk to the switch until after you have created the trunk in the
switch’s management software. Otherwise, a network loop will
result which can adversely affect network performance.
The default setting for the wiring configurations of the ports is auto-
MDI/MDIX. The default setting is appropriate for switch ports that
are connected to 10BASE-T and 100BASE-TX network devices
that also support auto-MDI/MDIX.
The default auto-MDI/MDIX setting is not appropriate for switch
ports that are connected to 10BASE-T and 100BASE-TX network
devices that do not support auto-MDI/MDIX and have a fixed wiring
configuration. For switch ports connected to those types of network
devices, you should disable auto-MDI/MDIX and set the wiring
configurations manually.
The appropriate MDI/MDIX setting for a switch port connected to a
10BASE-T and 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 straightthrough 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 MDIX. For
example, if a network device has a fixed wiring configuration of
MDI, you must disable auto-MDI/MDIX on the corresponding
switch port and manually set it to MDIX. 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.
62
Page 73
AT-x230-10GP, AT-x230-18GP, AT-x230-18GT and AT-x230-28GP Switches Installation Guide
The default speed setting for the ports is Auto-Negotiation. This
setting is appropriate for ports connected to network devices that
also support Auto-Negotiation.
The default speed setting of Auto-Negotiation is not appropriate for
ports connected to 10BASE-T and 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 10/1000BASE-T and 100BASE-TX 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.
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.
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.

7. Repeat steps 2 through 6 to install an additional SFP transceiver.
SFP transceivers are dust sensitive. Always keep the plug in the
optical bores when a fiber optic cable is not installed, or when storing
the SFP. When you do remove the plug, keep it for future use.
Unnecessary removal and insertion of an SFP transceiver can lead
to premature failure.
For information on the cable specifications of the SFP, consult the
documentation shipped with the SFP.

Troubleshooting
This chapter contains information on how to troubleshoot the switch if a
problem occurs.
For further assistance, please contact Allied Telesis Technical
Support at www.alliedtelesis.com/support.
Problem 1: The POWER 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 is probably operating in low power mode. To toggle
on the LEDs, press the ecofriendly button on the front panel for 1 to 4
seconds.
Problem 3: A twisted pair port on the switch is connected to a network
device but the port’s Link/Activity/Speed LED is off.
Solutions: The port is unable to establish a link to a network device. Try
the following:
Verify that the network device connected to the twisted pair port is
powered on and is operating properly.
Verify that the twisted pair cable is securely connected to the port
on the media converter channel and to the port on the remote
network device.
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, such as a powered off device.

Page 86
Chapter 3: Troubleshooting
Note
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. Cable requirements can be found in
Table 1, Table 3 and
Table 4.
A 1000BASE connection may require five to ten seconds to
establish a link.
Problem 4: The Link/Activity/Speed 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:
Verify that the 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 media converter channel and to the port on the remote network
device.
Check that the SFP module is fully inserted in the slot.
Verify that the operating specifications of the fiber optic ports on
the SFP transceiver and the 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, such as a powered off 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 management device, use its
management firmware to determine whether its port is enabled.
Test the attenuation 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: 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 shut down 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 shut down if it is in danger of overheating.
Problem 6: A port on the AT-x230-10GP, AT-x230-18GP, or
AT-x230-28GP switch is not providing power to a PoE device.
Solutions: Check 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
in the switch to the powered device. 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 x230 Series 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
Use the management software on the switch to determine whether
Table 3 and Table 4.
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.

Chapter 3: Troubleshooting
Problem 7: 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 occurs when a twisted pair port using AutoNegotiation is connected to a device with 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 on the switch so that both ports are using the
same duplex mode.
Problem 8: A port’s Link/Activity/Speed LED is blinking.
Solutions: The link between the port and the network device is
intermittent. Try the following:
Connect another network device with a different cable to the port. If
the Link LED remains steady on, then the problem is with the
original cable or the network device.
If the problem is with an SFP transceiver, check that the
transceiver is fully inserted in the slot.
