Twisted pair ports

Note
AT-x230-10GP and AT-x230-18GP Switches Installation Guide
The AT-x230-10GP and AT-x230-18GP Gigabit Ethernet Switches feature 8 and 16 twisted pair ports, respectively. 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, see “Connectors and port pinouts” on page 69.
The ports have a maximum operating distance of 100 m (328 feet). For 10 Mbps operation, the ports require Category 3 or better 100 ohm shielded or unshielded twisted pair cabling. For 100 or 1000Mbps operation, the ports require Category 5 or Enhanced Category 5 (5E) 100 ohm shielded or unshielded twisted pair cabling.
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.
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.

Chapter 1: Overview
Power over Ethernet (PoE)
The AT-x230-10GP and AT-x230-18GP 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). Both the AT-x230-10GP and AT-x230­18GP 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 AT-x230-10GP and AT-x230-18GP 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 device
classes
Powered devices are grouped into the five classes listed in Table 1 on page 17. The classes are based on the amount of power the devices require. Both the AT-x230-10GP and AT-x230-18GP switches support all five classes.

Power budget The AT-x230-10GP and AT-x230-18GP switches each have a power

budget of 124 and 247 watts, respectively. 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 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
19

Chapter 1: Overview
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.
20
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.

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 the AT-x230-10GP and AT-x230-18GP 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.

Selecting a site for the switch

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.
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.

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. Remove all equipment from the package and store the packaging material in a safe place.
2. Turn the switch over and place it on a table.

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.

AT-x230-10GP and AT-x230-18GP 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

Installing optional SFP transceivers

Note
Note
Warning
SFP
To install an SFP transceiver, perform the following procedure:
The transceiver can be hot-swapped; you do not need to power off the switch to install a transceiver. However, always remove the cables before removing the transceiver.
You should always install the transceiver before connecting the fiber optic cables to it.
1. Remove the transceiver from its shipping container and store the packaging material in a safe location.
AT-x230-10GP and AT-x230-18GP Switches Installation Guide
An SFP 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 transceiver.
2. Remove the dust plug from an SFP slot. See Figure 29.

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.
AT-x230-10GP and AT-x230-18GP Switches Installation Guide
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.
63
Page 74
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: Category 3 or better for 10 Mbps operation and Category 5 and Category 5E for 100 and 1000 Mbps operation.
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).

Page 75
AT-x230-10GP and AT-x230-18GP Switches Installation Guide
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 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 6: 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.
