Note

10/100/1000Base-T Twisted Pair Ports

This section describes the twisted pair ports on the switches. (This section does not apply to the AT-9408LC/SP Switch.)

Connector Type The ports are 8-pin RJ-45 connectors that use four pins at 10 or 100 Mbps

and all eight pins at 1000 Mbps. For the pin assignments, refer to “RJ-45 Twisted Pair Port Pinouts” on page 80.

Speed A port’s speed can be 10, 100, or 1000 Mbps. The speed can be set

automatically through Auto-Negotiation, the default setting, or manually with the AT-S63 Management Software.

To operate at 1000 Mbps, a twisted pair port must be set to Auto Negotiation. The speed of a twisted pair port cannot be manually set to 1000 Mbps.

Duplex Mode A twisted pair port can operate in either half- or full-duplex mode. (Full-

duplex mode is the only mode available when a port is operating at 1000 Mbps.) The twisted pair ports are IEEE 802.3u-compliant and AutoNegotiate the duplex mode setting.

You can disable Auto-Negotiation on one or all of the switch ports so that you can set the duplex mode manually through the AT-S63 Management Software.

In order for a switch port to successfully Auto-Negotiate its duplex mode with a 10 or 100 Mbps end node, the end node should also be configured for Auto-Negotiation. Otherwise, a duplex mode mismatch can occur. A switch port using Auto-Negotiation defaults to half-duplex if it detects that the end node is not using AutoNegotiation. This results in a mismatch if the end node is operating at a fixed duplex mode of full-duplex.

To avoid this problem when connecting an end node with a fixed duplex mode of full-duplex to a switch port, use the AT-S63 Management Software to disable Auto-Negotiation on the port and set the port speed and duplex mode manually.

AT-9400 Series Gigabit Ethernet Switches Installation Guide

Maximum

The ports have a maximum operating distance of 100 meters (328 feet).

Distance

Cable Type The cabling requirements for a 10/100/1000Base-T port are:

 For 10 Mbps operation: Standard TIA/EIA 568-B-compliant Category 3

or better shielded or unshielded cabling with 100 ohm impedance and a frequency of 16 MHz.

 For 100 Mbps operation: Standard TIA/EIA 568-A-compliant Category

5 or TIA/EIA 568-B-compliant Enhanced Category 5 (Cat 5e) shielded or unshielded cabling with 100 ohm impedance and a frequency of 100 MHz.

 For 1000 Mbps operation: Standard TIA/EIA 568-A-compliant

Category 5 or TIA/EIA 568-B-compliant Enhanced Category 5 (Cat 5e) shielded or unshielded cabling with 100 ohm impedance and a frequency of 100 MHz.

Auto-MDI/

MDI-X

The twisted pair ports on the switch are IEEE 802ab-compliant and feature auto-MDI/MDI-X. This feature, available when a port’s speed and duplex mode are set through Auto-Negotiation, automatically configures a switch port to MDI or MDI-X depending on the wiring configuration of the port on the end node. This allows you to connect any network device to a port on the switch using a straight-through twisted pair cable.

If Auto-Negotiation is disabled on a port and the speed and duplex mode are set manually, the auto-MDI/MDI-X feature is also disabled and the port’s wiring configuration defaults to the MDI-X setting. This setting can be configured with the AT-S63 Management Software.

Port Pinouts Refer to Table 13 on page 80 for the port pinouts when a twisted pair port

operates at 10 or 100 Mbps in the MDI configuration and Table 14 on page 80 for the MDI-X configuration. For port pinouts when a twisted pair port operates at 1000 Mbps, refer to Table 15 on page 81.

Chapter 1: Overview

Note

Fiber Optic Ports

This section applies to ports 1 through 8 on the AT-9408LC/SP Switch.

Connector Type The ports feature LC-duplex connectors.

Speed The ports have fixed speed of 1000 Mbps (1000Base-SX).

Maximum

Distance and

Cabling

The ports have a maximum distance of 275 meters (m) with 62.5/125 µm (core/cladding) multimode fiber optic cable and 550m with 50/125 µm multimode fiber optic cable.

For optical specifications, refer to “AT-9408LC/SP Switch 1000Base-SX Port Specifications” on page 82.

GBIC Transceiver Slots

Note

For interconnecting devices over large distances using fiber optic cable, the AT-9424T/GB Switch has two slots on the front panel labeled 23 and 24 for optional fiber optic Gigabit Interface Converter (GBIC) Ethernet transceivers. Figure 10 illustrates a GBIC transceiver.

AT-9400 Series Gigabit Ethernet Switches Installation Guide

Figure 10 GBIC Transceiver

GBIC transceiver slots 23 and 24 are paired with twisted pair ports 23R and 24R. Only one port or transceiver in a pair can be operational at a time and a link on a transceiver port takes priority over a link on a twisted pair port. For further information, refer to “Redundant Twisted Pair Ports” on page 32.

For a list of supported GBIC transceivers, contact your Allied Telesis sales representative.

Chapter 1: Overview

Note

SFP Transceiver Slots

Several of the AT-9400 Switches feature slots for optional Gigabit Ethernet SFP transceivers for interconnecting network devices over large distances using fiber optic cable. With the exception of the AT-9408LC/SP Switch, each SFP slot is paired with a twisted pair port. A link on an SFP transceiver takes priority in the event both an SFP transceiver and its paired twisted pair port have established links to their respective end nodes. For further information, refer to “Redundant Twisted Pair Ports” on page 32.

Redundant Twisted Pair Ports

Some AT-9400 Switches have two or four twisted pair ports that are paired with GBIC or SFP slots. The twisted pair ports are identified with the letter “R” for “Redundant” as part of their number on the front faceplate of the unit. The ports and slots are listed in Table 2.

Follow these guidelines when using these ports and slots:

 Only one port in a pair — either the twisted pair port or a

corresponding GBIC or SFP module — can be active at a time.

 The twisted pair port is the active port when its GBIC or SFP slot is

empty, or when a GBIC or 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 a GBIC or 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 GBIC or SFP module.

 In nearly all cases, a twisted pair port and a GBIC or SFP module

share the same configuration settings, including port settings, VLAN assignments, access control lists, and spanning tree.

 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 a GBIC or SFP module establishes a link with an end node.

Note

AT-9400 Series Gigabit Ethernet Switches Installation Guide

The expansion slot on the AT-9424Ts, AT-9424Ts/XP, and AT-9448Ts/XP Switches accommodates the optional AT-StackXG Stacking Module. The module creates a stack of up to five or eight switches, depending on the model. The switches of a stack function as a single, logical unit where network functions, such as the spanning tree protocol and static port trunks, can span across all the ports of the switches in the stack. This increases network bandwidth and simplifies network management.

For further information and installation instructions, refer to the AT-9400 Stack Installation Guide.

Do not install the AT-StackXG Stacking Module into a switch until you have read the Software Release Notes included with the latest release of the AT-S63 Management Software. This module may not be appropriate for all network environments because a stack does not support all the features of the AT-S63 Management Software.

Chapter 1: Overview

Note

Terminal Port

The terminal port is used to establish a local (out-of-band) management session with the switch and configure the switch’s operating parameters. You establish a local management session with the switch by connecting a terminal or a personal computer with a terminal emulation program to the port.

You can use the AT-9400 Switch as an unmanaged switch if the default settings of the AT-S63 Management Software are adequate for your network. For a list of the default settings, refer to the AT-S63 Management Software Features Guide.

The terminal port has an RJ-45 style connector. An RJ-45 to RS-232 management cable is supplied with the switch.

The terminal port is set to the following specifications:

 Default baud rate: 9600 bps (Range is 9600 to 115200 bps)

 Data bits: 8

 Parity: None

 Stop bits: 1

 Flow control: None

These settings are for a DEC VT100 or ANSI terminal, or an equivalent terminal emulation program.

Power Over Ethernet

The following discussion applies only to the AT-9424T/POE Gigabit Ethernet switch.

The twisted pair ports on the AT-9424T/POE switch feature Power over Ethernet (PoE). PoE is a mechanism for supplying power to network devices over the same twisted pair cables used to carry network traffic. This feature can simplify network installation and maintenance by allowing you to use the switch as a central power source for other network devices.

A device that receives its power over an Ethernet cable is called a powered device. Examples of such devices can be wireless access points, IP telephones, web cams, and even other Ethernet switches. A powered device connected to a port on the switch will receive both network traffic and power over the same twisted pair cable.

There are several advantages that the PoE feature of the AT-9424T/POE switch adds to the installation and maintenance of your network. First, because the switch acts as the central power source for your powered devices, adding an uninterruptible power source (UPS) to the switch increases the protection not just to the switch itself from possible power source problems but also to all of the powered devices connected to it. This can increase the reliability of your network by minimizing the impact to network operations from a power failure.

AT-9400 Series Gigabit Ethernet Switches Installation Guide

PoE can also simplify the installation of your network. A frequent issue in selecting a location for a network device is whether there is a power source nearby. This often limits equipment placement or requires the added cost and time of having additional electrical sources installed. With PoE, you can install PoE-compatible network equipment wherever they are needed without having to worry about whether they are near a power source.

The switch automatically determines whether or not a device connected to a port is a powered device. A powered device has a signature resistor or signature capacitor that the switch can detect over the Ethernet cabling. If the resistor or capacitor is present, the switch assumes that the device is a powered device.

Power Budgeting The AT-9424T/POE Gigabit Ethernet Switch provides a of 15.4 W

maximum of power per port on all 24 ports for a total power consumption of 370 W, while at the same time furnishing standard 10/100/1000 Mbps Ethernet functionality.

The AT-9424T/POE smart power management functionality supports any combination of Ethernet ports (1-24) that supply power for IEEE 802.3af Class 0, 1, 2, or 3 powered devices up to a maximum of 370 watts, as

Chapter 1: Overview

described in Table 8. .

Table 8. IEEE 802.3af Class vs. Power Levels

Class Usage

Minimum Power

Levels Output at

the PSE

Maximum Power Levels Output at

the PD

0 Default 15.4W 0.44W to 12.95W

1 Optional 4.0W 0.44W to 3.84W

2 Optional 7.0W 3.84W to 6.49W

3 Optional 15.4W 6.49W to 12.95W

A port connected to a network node that is not a powered device (that is, a device that receives its power from another power source) functions as a regular Ethernet port, without PoE. The PoE feature remains enabled on the port but no power is delivered to the device.

Implementation A standard Ethernet twisted pair cable contains four pairs of strands for a

total of eight strands. 10/100/1000 Mbps network traffic requires only four strands (1, 2, 3, and 6), leaving four strands in the cable unused (4, 5, 7, and 8).

The PoE standard, IEEE 802.3af, describes two alternative ways for delivering power to a powered device (PD) over twisted pair cabling. Alternative A uses the same strands that carry the network traffic. Alternative B uses the spare strands. The PoE implementation on the AT9424T/POE Gigabit Ethernet Switch is Alternative A, where power is transmitted over strands 1, 2, 3, and 6.

PD’s that comply with the IEEE 802.3af standard typically support both power delivery methods. So long as a PD is compliant with the standard, it should be able to receive its power from the switch while using either a straight or cross-over cable. The PoE feature on the AT-9424T/POE Gigabit Ethernet Switch should also work with most legacy PD’s as long as the device can be powered on pins 1, 2, 3, and 6. A legacy device is a node that was manufactured before the IEEE 802.3af standard was completed and, consequently, may not adhere to the standard. If this is the case, a cross-over (MDI-X) cable may be needed to insure that the DC polarity is correct.

AT-RPS3204 Redundant Power Supply

AT-PW

R3204

The RPS connector on the back panel of the switch connects to the optional AT-RPS3204 redundant power supply unit, shown in Figure 14. The unit can provide power to the switch in the event that the switch’s internal power supply fails.

The AT-RPS3204 redundant external power supply features one preinstalled AT-PWR3204 Power Module and three empty slots for additional power modules. Each power module can support one switch. When fully populated with AT-PWR3204 Power Modules, the AT-RPS3204 unit can support up to four switches simultaneously. For information about installing an AT-RPS3204 unit, consult the documentation shipped with the unit.

The auto-MDI/MDI-X feature on the twisted pair ports automatically configures the MDI/MDI-X setting when a link is established with an end node. Available when a port is at the default setting of AutoNegotiation, this feature allows you to use a straight-through twisted pair cable when connecting any type of network device to a port.

Disabling Auto-Negotiation on a port and setting the speed and duplex mode manually also disables the auto-MDI/MDI-X feature. A port where Auto-Negotiation has been disabled defaults to MDI-X. Disabling Auto-Negotiation may require manually configuring a port’s MDI/MDI-X setting or using a crossover cable.

AT-9400 Series Gigabit Ethernet Switches Installation Guide

Note

The speed of a 10/100/1000Base-T twisted pair port on the switch must be set to Auto -Negotiation, the default setting, if the port is to operate at 1000 Mbps. A 10/100/1000Base-T twisted pair port cannot be manually set to 1000 Mbps.

AT-9400 Series Gigabit Ethernet Switches Installation Guide

Cabling the Twisted Pair or Fiber Optic Ports

Observe the following guidelines when connecting a twisted pair or fiber optic cable to a port 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 on the switch are auto-MDI/MDI-X, any

type of network device can be connected to a port on the switch using a straight-through twisted pair cable. If you disable Auto-Negotiation on the port, the port defaults to MDI-X. For instructions on how to configure a port, refer to the AT-S63 Management Software User Guides.

 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 forming the loop until after you have activated a spanning tree protocol on the switch. Data loops can adversely affect network performance. For background information on the different types of spanning tree protocols supported by the switch, refer to the AT-S63 Management Software Features Guide.

 If you are creating a port trunk, you must configure the switch’s

management software before connecting the cables of the trunk to the switch. Otherwise, a network loop will result which can adversely affect network performance. For background information on the types of port trunks supported by the switch, refer to the AT-S63 Management Software Features Guide.

 In order for a switch port to successfully Auto-Negotiate its duplex

mode with an end node, the end node should also be using AutoNegotiation. Otherwise, a duplex mode mismatch can occur. A switch port using Auto-Negotiation defaults to half-duplex 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.

To avoid this problem, disable Auto-Negotiation on a switch port and set the port’s speed and duplex mode manually if the end node has a fixed duplex mode of full-duplex.

Chapter 2: Installing the Switch

Starting a Local Management Session

The procedure in this section explains how to start a local (out-of-band) management session using the RJ-45 terminal port on the switch. You can use a local management session to configure the switch’s operating parameters and view performance and error statistics.

If your network already has an enhanced stack of Allied Telesis Layer 2 or Layer 2+ switches, you might be able to initially manage the new switch by connecting, locally or remotely, to the master switch of the stack and changing to the new switch through the management software. For overview information on enhanced stacking, refer to the AT-S63 Management Software Features Guide.

To start a local management session, perform the following procedure:

1. Connect the RJ-45 end of the management cable included with the AT-9400 Switch to the Terminal Port on the front panel of the switch, as shown in Figure 29.

Figure 29. Connecting the Management Cable to the RJ-45 Terminal Port

on the Switch

2. Connect the other end of the cable to an RS-232 port on a terminal or a personal computer with a terminal emulation program.

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

 Baud rate: Default is 9600 bps (Range is 9600 to 115200 bps)

 Data bits: 8

 Parity: None

Chapter 3: Troubleshooting

Power LED is Off

Check the PWR LED on the front of the switch. If the LED is off, indicating that the unit is not receiving power, do the following:

 Make sure 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 using a different power cord.

 Check that the voltage from the power source is within the required

levels for your region.

Twisted Pair Port Link LED is Off

Note

When a twisted pair port on the switch is connected to a properly operating end node, the Link LED for the port should be on. If a Link LED is off, do the following:

 Verify that the end node connected to the port is powered ON and is

operating properly.

 Check that the twisted pair cable is securely connected to the port on

the switch and to the port on the end node.

 Make sure that the twisted pair cable does not exceed 100m (328 ft).

 Verify that you are using the appropriate category of twisted pair cable.

For information, refer to Table 9 on page 50.

 Determine if a crossover cable is required. Since the twisted pair ports

feature auto MDI/MDI-X, you should be able to use a straight-through cable regardless of the type of device you connect to a port. However, if you disable Auto-Negotiation on a port and set a port’s speed and duplex mode manually, the port defaults to MDI-X. Disabling AutoNegotiation may require manually configuring a port’s MDI/MDI-X setting or using a crossover cable.

AT-9400 Series Gigabit Ethernet Switches Installation Guide

 Make sure that the operating parameters of the port on the switch are

compatible with the end node to which the port is connected. This may require using the switch’s management software.

A 1000Base-T connection can take from five to ten seconds to establish a link.

 If a switch port is using Auto-Negotiation, the default setting, to set its

speed and duplex mode settings, the end node connected to the port should also be using Auto-Negotiation to prevent a duplex mode mismatch. This can occur because a switch port that is using AutoNegotiation will default to the half-duplex mode if it detects that the end node is not using Auto-Negotiation. If the end node is operating at a fixed duplex mode of full-duplex, the result will be a mismatch of settings on the two devices, with the switch port using half-duplex and the end node using full-duplex.

To avoid this problem, you should disable Auto-Negotiation on a switch port and set the port’s speed and duplex mode manually if the end node has a fixed duplex mode of full-duplex.

 The switch has a bad cable detection feature that enables it to

determine if a twisted pair cable has a electrical short that might cause a network loop. If the switch detects a bad cable on a port, it does not establish a link on that port. Try replacing the cable.

Chapter 3: Troubleshooting

Note

Fiber Optic Port Link LED is Off

When a fiber optic port on the switch is connected to a properly operating end node, the Link LED for the port should be on. If a Link LED is off, do the following:

 Verify that the end node connected to the port is powered ON and is

operating properly.

 Check that the fiber optic cable is securely connected to the port on

the switch and the port on the end node.

 If the fiber optic port is on a GBIC, SFP, or XFP transceiver, check to

be sure that the transceiver is firmly inserted into the slot on the switch.

 Make sure that you are using the appropriate type of fiber optic cable

and that the cable length does not exceed the allowed maximum distance. The cable specifications for the ports on the AT-9408LC/SP Switch are listed in Table 10 on page 51. For cable specifications for an SFP or GBIC module, refer to the installation instructions shipped with the module.

 Use a fiber optic tester to test the attenuation on the cable and the

strength of the optical signal. The operating specifications for the ports on the AT-9408LC/SP Switch are listed in Table 16 on page 82. For operating specifications for an SFP or GBIC module, refer to the installation instructions shipped with the module.

 Check that the operating specifications (for instance, wavelength and

maximum operating distance) of the fiber optic port on the remote end node are compatible with the fiber optic port on the switch.

 Check to be sure that the fiber optic ports on the switch and on the end

node are operating at the same speed and duplex mode.

 A fiber optic cable contains two separate fiber strands. One strand is

for receiving data and the other is for transmitting data. When you connect a fiber optic cable to a port, be sure that the receive fiber connector is connected to the transmit connector on the remote end node, and that the transmit fiber connector is connected to the receive connector on the remote node.

The L/A LED for an SFP transceiver slot may remain ON if you remove the transceiver when it has a link to an end node without first disconnecting the fiber optic cable. The L/A LED will change to OFF the next time an SFP module is installed in the slot. To avoid this, always disconnect the fiber optic cable before removing a transceiver.

AT-9400 Series Gigabit Ethernet Switches Installation Guide

Note

Transceiver is Installed but the Status is “Not Present”

If a GBIC, SFP, or XFP transceiver is installed in a transceiver slot but the Uplink Information menu in the AT-S63 Management Software interface displays “Not Present” for that port, do the following:

 Verify that the transceiver is completely inserted in the slot on the front

of the switch.

The uplink status does not reflect whether a fiber optic cable is connected to the transceiver.
