Supported SFP
Modules
Here is a list of supported Allied Telesis SFP products:
AT-SPTX (See ”Guidelines for Using the AT-SPTX Module”.)
AT-SPSX
AT-SPSX/I
AT-SPSX2
AT-SPEX
AT-SPLX10

The SFP slots support 1000Mbps speed only.
Guidelines for
Using the AT-
SPTX Module
22
Allied Telesis supports the AT-SPTX module on the AT-FS980M/28 switch with some restrictions. The AT-FS980M/28 switch has four SFP slots. Before using the AT-SPTX SFP module on the AT-FS980M/28 switch, review the following guidelines:
The AT-FS980M/28 switch can have up to two AT-SPTX modules.
When you use two AT-SPTX modules on the he AT-FS980M/28
switch, you must use port 25 and port 26.
When two AT-SPTX modules are used on port 25 and port 26, you
can use only the AT-SP10TW1 or AT-StackXS/1.0 module on port 27 and port 28.
The operating temperature of the AT-FS980M/28 switch using the
AT-SPTX module must be between 0° C to 40° C (32° F to 104° F).

Chapter 1: Overview

10/100Base-TX Twisted Pair Ports

The switches have 8, 16, 24, or 48 10/100Base-TX ports.
Basic Features Here are the basic features of the 10/100 Mbps twisted pair ports:
10Base-T and 100Base-TX compliant
IEEE 802.3u Auto-Negotiation compliant
Auto-MDI/MDIX
100 meters (328 feet) maximum operating distance
IEEE 802.3x flow control in 10/100Base-TX full-duplex operation
Support for jumbo frames up to 10KB
Support for store-and-forward switching
RJ-45 connectors
Backpressure Support for IEEE 802.3x backpressure in 10/100Base-TX half-duplex
operation depends upon a switch model:
Backpressure is supported on the AT-FS980M/9,
AT-FS980M/9PS, AT-FS980M/18, and AT-FS980M/18PS switches.
To support backpressure on the AT-FS980M/28 or
AT-FS980M/28PS switch, you must upgrade the management software to version 5.4.6-2.1 or later.
Backpressure is not supported on the AT-FS980M/52 and
AT-FS980M/52PS switches.
Speed 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.
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.
24
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.
Page 25
FS980M Series Fast Ehternet Managed Switches Installation Guide
Note
The speed and duplex mode settings of a port may be set independently of each other. For example, a port may be configured such that its speed is set manually while its duplex mode is established through Auto­Negotiation.
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 a 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 through the management software.
Wiring
Configuration
Maximum
Distance
Power Over
Ethernet
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.
The ports have a maximum operating distance of 100 meters (328 feet).
The 10/100Base-TX ports on the AT-FS980M/9PS, AT-FS980M/18PS, AT-FS980M/28PS, and AT-FS980M/52PS switches support Power over Ethernet (PoE), which is a standard whereby DC power is provided by the switch to network devices over the network twisted pair cables. The switches support PoE (IEEE 802.3af) and PoE+ (IEEE 802.3at). For background information, refer to “Power Over Ethernet” on page 31.

10/100/1000Base-T Twisted Pair Ports

The AT-FS980M/9, AT-FS980M/9PS, AT-FS980M/18 and AT-FS980M/18PS switches have one or two 10/100/1000Base-T ports. The two ports of the AT-FS980M/9, AT-FS980M/9PS, AT-FS980M/18, and AT-FS980M/18PS switches are paired with SFP slots to form combo ports.
Basic Features Here are the basic features of the 10/100/1000 Mbps twisted pair ports:
10Base-T, 100Base-TX, and 1000Base-T compliant
IEEE 802.3u Auto-Negotiation compliant
Auto-MDI/MDIX
100 meters (328 feet) maximum operating distance
IEEE 802.3x flow control in 10/100Base-TX full-duplex operation
IEEE 802.3x backpressure in 10/100Base-TX half-duplex
operation
Support for jumbo frames up to 10KB
Support for store-and-forward switching
RJ-45 connectors
Speed The ports can operate at 10, 100, or 1000 Mbps. The speeds may be set
manually using the management software or automatically with Auto­Negotiation (IEEE 802.3u), the default setting.
The ports must be set to Auto-Negotiation to function at 1000 Mbps. They are not compatible with devices that are not IEEE 802.3u compliant.
Duplex Mode The twisted pair ports can operate in either half- or full-duplex mode. The
duplex modes, like port speeds, may be set manually using the management software or automatically with Auto-Negotiation (IEEE
802.3u), the default setting.
The speed and duplex mode settings of a port may be set independently of each other. For example, a port may be configured such that its speed is set manually while its duplex mode is established through Auto­Negotiation.
27
Page 28
Chapter 1: Overview
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 a 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 through the management software.
Wiring
Configuration
Maximum
Distance

Ethernet
The wiring configuration of a port operating at 10 or 100 Mbps can be MDI or MDI-X. The wiring configurations of a switch port and a network device connected with straight-through twisted pair cabling have to be opposite, such that one device is using MDI and the other MDI-X. For instance, a switch port has to be set to MDI-X if it is connected to a network device set to MDI.
You may set the wiring configurations of the ports manually or let the switch configure them automatically with auto-MDI/MDI-X (IEEE 802.3ab­compliant). This feature enables the switch to automatically negotiate with network devices to establish the proper settings.
The MDI and MDI-X settings do not apply when the ports are operating at 1000 Mbps.
The ports have a maximum operating distance of 100 meters (328 feet).
The 10/100/1000Base-T ports do not support PoE.

Combo Ports

The AT-FS980M/9, AT-FS980M/9PS, AT-FS980M/18, and AT-FS980M/18PS switches have one or two pairs of combo ports. Each combo port consists of one 10/100/1000Base-T twisted-pair port and one slot for an SFP transceiver. The twisted-pair port of combo ports is identified with the letter “R” for “Redundant” on the front panel of the switch. The combo ports and SFP slots are listed in Table 5.
Table 5. Combo Ports

9R 9
17R 17
18R 18
The combo ports have the guidelines listed here:
Only one port in a pair, either the twisted-pair port or a
corresponding SFP module, can be active at a time.
The twisted-pair port is the active port when its SFP slot is empty,
or when an SFP module is installed, but has not established a link to an end node.
The twisted-pair port automatically changes to the redundant
status mode when an SFP module establishes a link with an end node.
A twisted-pair port automatically transitions back to the active
status when the link is lost on the SFP module.
In nearly all cases, a twisted-pair port and an SFP module share
the same configuration settings, including port settings, VLAN assignments, access control lists, and spanning tree.
30
An exception to the shared settings is port speed. If you disable
Auto-Negotiation on a twisted-pair port and set the speed and duplex mode manually, the speed reverts to Auto-Negotiation when an SFP module establishes a link with an end node.

Power Over Ethernet

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 to make it easier to install a network. The placement of network devices is often limited by whether there are power sources 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 PoE­compatible 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 PoE 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.
FS980M Series Fast Ehternet Managed Switches Installation Guide
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-FS980M/9PS, AT-FS980M/18PS, AT-FS980M/28PS, and AT-
FS980M/52PS 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 power budget is the maximum amount of power the switch can
provide at one time to the powered devices. The AT-FS980M/9PS, AT­FS980M/18PS, AT-FS980M/28PS, and AT-FS980M/52PS switches support both Power over Ethernet (PoE) and Power over Ethernet Plus (PoE+) on 10/100Mbps twisted pair ports.
31
Page 32
Chapter 1: Overview
Table 6 shows PoE specifications for each model.
Table 6. PoE+ Switches
PoE+ Switch

AT-FS980M/9PS 150 watts 0 to 4 8 5
AT-FS980M/18PS 250 watts 0 to 4 16 8
AT-FS980M/28PS 375 watts 0 to 4 24 12
AT-FS980M/52PS 375 watts 0 to 4 24 12
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 of the devices. 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 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.
Powered devices are grouped into the five classes listed in Table 7 on page 33. The classes are based on the amount of power the devices require. The switches support all five classes.

3 15.4W 6.49W to 12.95W
4 30.0W 12.95W to 25.5W
PoE+ Class 4 powered devices (IEEE 802.3at) with a power range of 12.95 to 25.5 watts must use LLDP to identify their power requirements to the switch. Non-compliant PoE+ powered devices that do not support LLDP will be limited to 802.3af (15.4 watts) power levels.
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.
33
Page 34
Chapter 1: Overview
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. By limiting 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.

Console Port

Note
FS980M Series Fast Ehternet Managed Switches Installation Guide
The Console port is used to configure the features and parameter settings of the switch. 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, you 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 which 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
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
These settings are for a DEC VT100 or ANSI terminal, or an equivalent terminal emulation program.

Choosing a Site for the Switch

Observe these requirements when planning the installation of the switch.
If you plan to install the switch in an equipment rack, the rack
should be 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, the table should be 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.
The site should not be a wiring or utility box because the switch will
overheat and fail from inadequate airflow.
Switches should not be stacked on top of one another on a table or desktop because that could present a personal safety hazard if you need to move or replace switches. E91

Chapter 3: Cabling the Networking Ports

Cabling the Twisted Pair Ports

This section contains the guidelines to cabling the twisted pair and fiber optic ports.
Twisted Pair
Ports
Here are the guidelines to cabling the 10/100Base-TX twisted pair ports:
The cable specifications are listed in Table 3 on page 26 and
Table 4 on page 29.
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.
58
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 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 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.
Page 59
FS980M Series Fast Ehternet Managed Switches Installation Guide
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.

Warning

Installing Optional SFP Transceivers

Review the following guidelines before installing optional SFP transceivers in the switch:
SFP transceivers can be hot-swapped while the switch is powered
on. However, you should always disconnect the fiber optic cable first before removing a transceiver.
You should install the 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.
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. E87
To install an SFP transceiver:
1. Remove the transceiver from its shipping container and store the packaging material in a safe location.
2. If you are installing the transceiver in the top SFP slot, position the transceiver with the Allied Telesis label facing up. If you are installing the transceiver in the bottom slot, position the transceiver with the label facing down.
3. Slide the transceiver into the slot until it clicks into place, as shown in Figure 31 on page 61.

Troubleshooting

This chapter contains suggestions 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: All the LEDs on the switch are off.
Solutions: Try the following:
Press the eco-friendly button on the front panel to see if the switch
is operating in the low power mode with the LEDs off. You can also toggle the LEDs off and on with the ECOFRIENDLY LED and NO ECOFRIENDLY LED commands in the Global Configuration mode of the command line interface.
Verify that the power cord is securely connected to the power
source and 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 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 cable is securely connected to the ports on the
switch and network device.
Verify that the port is connected to the correct twisted pair cable.
Verify that the network device connected to the twisted pair port is
powered on and is operating properly.
67
Page 68
Chapter 5: 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 3 on page 26 and Table 4 on page 29.
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:
Check that the SFP module is fully inserted in the slot.
Verify that the remote network device connected to the fiber optic
port is powered on and operating properly.
Verify that the fiber optic cable is securely connected to the ports
on the SFP module and remote network device.
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.
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 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).
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 switch so that both ports are using the same duplex mode.
68
Page 69
FS980M Series Fast Ehternet Managed Switches Installation Guide
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.
For switches that have a ventilation fan, use the SHOW SYSTEM
ENVIRONMENT command in the Privileged Exec mode to verify that it is operating correctly.
Verify that the location of the switch provides adequate airflow. The
unit will shutdown if it is in danger of overheating.
