10/100Base-TX Twisted Pair Ports

The x310 Series switches have 24 or 48 10/100Base-TX ports, depending on the model.

Speed

The ports can operate at either 10 or 100 Mbps. The speeds may be set manually using the management software or automatically with Auto-

Negotiation (IEEE 802.3u), the default setting.

Duplex Mode

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.

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


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 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 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.

30

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.

Table 4 Combo Port Pairs

25

26

50

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-x310-

50FT 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:









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.

32


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.

33

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:

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.







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 auto-

MDI/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

86




 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.

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.

Installing SFP

Modules

To install SFP transceivers in slots 25 and 26 of the 26-port switches or slots 49 and 50 of the 50-port switches, perform the following procedure:

1. Remove the dust plug from a transceiver slot on the switch. Refer to

Figure 40.

Figure 40. Removing the Dust Plug from an SFP Slot

2. Remove the transceiver from its shipping container and store the packaging material in a safe location.

3. If you are installing the transceiver in a top slot, position the transceiver with the handle on top. If you are installing the transceiver in a bottom slot, position the transceiver with the handle beneath the module.

4. Slide the transceiver into the slot until it clicks into place. Refer to

Figure 41.

Figure 41. Installing an SFP Transceiver

Monitoring the Initialization Processes

It takes about one and a half minutes for the switch to initialize its management software programs and features, and load the default configuration. You may monitor the progress of the initialization process by watching the switch ID LED. It displays the number “8” for the first minute and afterwards the number “1.”

You may also monitor the bootup sequence by connecting a terminal or computer that has a terminal emulator program to the Console port on the

master switch. The messages are given in Figure 49 here to Figure 51 on page 99. The messages may differ slightly depending on whether your

switch is a PoE or non-PoE model.

After the switch has initialized its management software, go to

“Configuring the Switch for Stand-alone Operations” on page 100.

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 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

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 52 on page 101.

100


Figure 52. Connecting the Management Cable to the Console Port

2. Connect the other end of the cable to an RS-232 port on a terminal or

PC with a terminal emulator program.

3. Configure the terminal or terminal emulator program as follows:











Baud rate: 9600 bps (The baud rate of the Console Port is adjustable from 1200 to 115200 bps. The default is 9600 bps.)

Data bits: 8

Parity: None

Stop bits: 1

Flow control: None

Note

The port settings are for a DEC VT100 or ANSI terminal, or an equivalent terminal emulator program.

4. Press Enter.

You are prompted for a user name and password.

5. When prompted for a user name, go to “Disabling VCStack” on page 102.

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 53. is displayed.

3. Review the following items:

 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.

102




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.

4. Move to the Global Configuration mode by entering the ENABLE and

CONFIGURE TERMINAL commands, as shown in Figure 55.

awplus> enable awplus# configure terminal

Enter configuration commands, one per line. End with CNTL/Z awplus(config)#

Figure 55. Moving to the Global Configuration Mode

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 56 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. If the ID number is “0,” the switch is ready for normal 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 number is not “0,” repeat this procedure.

104


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:























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).

108


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 Auto-

Negotiation 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-x310-

26FP 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.

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.
