Chapter 1: Overview 10/100/1000Base-T Twisted-Pair Ports A twisted-pair cable port is shown in Figure 7. Figure 7. Twisted-Pair Cable Port See Figure 19 on page 84 for the pin layout to a port and RJ-45 connector. 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. Note The ports must be set to Autonegotiation to function at 1000 Mbps.
AT-9000 Gigabit Ethernet Switch Installation Guide Note A switch port connected to a host device that does not support Autonegotiation, and has a fixed duplex mode of full-duplex, should not set its duplex mode with Autonegotiation. A duplex-mode mismatch in which a switch port and a host device operate at different duplex modes may occur. The duplex modes of switch ports that are connected to host devices that do not support Autonegotiation should be set manually through the management software.

Yes No No Yes No No No No No Standard TIA/EIA 568A-compliant Category 5 shielded or unshielded cabling with 100 ohm impedance and a frequency of 100 MHz.
AT-9000 Gigabit Ethernet Switch Installation Guide Power Over Ethernet The AT-9000/12POE and AT-9000/28POE switches feature Power over Ethernet (PoE) on the 10/100/1000Base-TX ports. PoE is used to supply power to host devices over the same twisted-pair cables that carry the network traffic. The main advantage of PoE is that it makes it easier to install a network. The placement of host devices is often limited by whether there are power sources nearby.
Chapter 1: Overview Powered Device Classes Powered devices are grouped into the five classes listed in Table 2. The classes are based on the amount of power the devices require. The switches support all five classes. Table 2. IEEE Powered Device Classes Class Power Budget Maximum Power Output from a Switch Port PD Power Range 0 15.4W 0.44W to 12.95W 1 4.0W 0.44W to 3.84W 2 7.0W 3.84W to 6.49W 3 15.4W 6.49W to 12.95W 4 30.0W 12.95W to 25.
AT-9000 Gigabit Ethernet Switch Installation Guide 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.
Chapter 1: Overview Wiring Implementation The IEEE 802.3af standard defines two methods by which a PSE, such as the switch, can transmit DC power over twisted-pair cables to PDs. These methods, known as modes A and B, identify the wire strands the switch should use when sending DC power to a PD. Twisted-pair cabling typically consists of eight strands.
AT-9000 Gigabit Ethernet Switch Installation Guide SFP Slots The AT-9000/12POE, AT-9000/28, AT-9000/28POE, and AT-9000/28SP switches have four slots for 100Mbps 100Base-FX or 1000Mbps 1000Base-SX/LX fiber optic transceivers. The transceivers can be used to connect the switches to other host devices over large distances, build a high-speed backbone network between host devices, or connect highspeed devices, such as servers, to your network.
Chapter 1: Overview Port speed is an exception to the shared settings of the twisted-pair port and SFP slot of a combo port. If you disable Autonegotiation on the twisted-pair port (and set the speed and duplex mode manually), the switch will reactivate Autonegotiation when an SFP module establishes a link with an end node.
AT-9000 Gigabit Ethernet Switch Installation Guide Combo Ports The AT-9000/28, AT-9000/28POE, and AT-9000/28SP switches have four combo pairs of uplink ports, each consisting of one slot for an SFP transceiver and a redundant 10/100/1000 Base-T twisted-pair port. These combo ports are numbered 25 through 28 on the switches. The twistedpair ports in each of the combo pairs are identified with the letter “R” for “Redundant” as part of their number on the front faceplate of the unit.
Chapter 1: Overview Note For a list of supported SFP transceivers for the AT-9000 Series Managed Layer 2 Gigabit Ethernet Switches, contact your Allied Telesis sales representative.
AT-9000 Gigabit Ethernet Switch Installation Guide Console Port 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 use the management cable included with the switch.
Chapter 1: Overview LEDs Here are descriptions of the switch LEDs. System LEDs There are two system LEDs, the Power (PWR) LED and System (SYS) LED, as shown in Figure 8. Figure 8. Power and System LEDs The system LED states are described in Table 4. Table 4.

The SFP LINK/ACT LEDs are illustrated in Figure 11, and their function is described in Table 8: LINK/ACT LEDs Figure 11. SFP LINK/ACT LEDs Table 8.
Chapter 1: Overview ecoFriendly Button The ecoFriendly button enables the Low Power Mode (LPM) feature. This mode allows you to conserve power by turning off the port and MODE LEDs when they are not required. To toggle the LEDs on or off, press the ecoFriendly button, located on the front panel of the switch. The LPM feature does not affect the network operations of the switch or the Power (PWR) and System (SYS) LEDs. The front panel ecoFriendly button is illustrated in Figure 12. Figure 12.
AT-9000 Gigabit Ethernet Switch Installation Guide Power Supplies The AT-9000/12POE, AT-9000/28, AT-9000/28SP, and AT-9000/52 switches have one AC power supply. The AT-9000/28POE switch has two AC power supplies. The supplies are not field-replaceable. Excluding PoE operation, only one power supply is active at a time in the AT-9000/28POE switch. The second power supply operates in a redundant state and is automatically activated by the switch if the active power supply loses power or fails.
Chapter 1: Overview Power Connectors The AT-9000/12POE, AT-9000/28, AT-9000/28SP, and AT-9000/52 switches have one AC power supply socket on the back panel. The AT-9000/28POE switch has two AC power supply sockets. AC switches are powered on or off by connecting or disconnecting the power cords.

Chapter 4 Cabling the Networking Ports Observe the following guidelines when connecting a twisted-pair cable to a port on the switch: The cable specifications for the 10/100/1000Base-T twisted pair ports are listed in Table 1 on page 27. 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.
AT-9000 Gigabit Ethernet Switch Installation Guide 60 The default speed setting for the ports is Autonegotiation. This setting is appropriate for ports connected to host devices that also support Autonegotiation. The default speed setting of Autonegotiation is not appropriate for ports connected to 10/100Base-TX host devices that do not support Autonegotiation and have fixed speeds.
Chapter 5 Powering On the Switch This chapter contains the following sections: “Applying AC Power” on page 62 “Starting a Local Management Session” on page 64 “Management Methods” on page 66 “Adding a Management IP Address” on page 69 61
AT-9000 Gigabit Ethernet Switch Installation Guide Applying AC Power Consider the following items as you power on the switch: All of the models have one power supply, except for the AT-9000/ 28POE switch, which has two power supplies with separate connectors. The AT-9000/28POE switch supports 370 watts of PoE only when both internal power supplies are connected to power sources. The switch has a PoE budget of 185 watts if just one power supply is functional.
Chapter 5: Powering On the Switch 2. Connect the other end of the power cord to an appropriate AC power outlet. For power specifications for the switch, refer to “Power Specifications” on page 82. 3. When power is applied, the switch begins to load the Management Software. The loading process takes less than a minute to complete. The switch is now ready for network operations.
AT-9000 Gigabit Ethernet Switch Installation Guide 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. To start a local management session, perform the following procedure: 1.
Chapter 5: Powering On the Switch 4. Press Enter. You are prompted for a user name and password. 5. To configure the switch settings, enter “manager” as the user name. The default password for manager access is “friend.” User names and passwords are case sensitive. 6. The local management session starts, and the command line interface prompt is displayed. For information about the command line interface, refer to the AT-9000 Series Management Command Line Interface User’s Guide.
AT-9000 Gigabit Ethernet Switch Installation Guide Management Methods You may use the following methods and tools to manage AT-9000 series switches: Local Management Local management Telnet client Secure Shell (SSH) client HTTP non-secure and HTTPs secure web browser SNMPv1, v2c, v3 Local management uses the Console port on the switch. It is commonly referred to as out-of-band management because the management sessions are not conducted over your network.
Chapter 5: Powering On the Switch Secure Shell Management Secure Shell (SSH) management is similar to Telnet management in that you may use it, together with the command line interface, to manage all of the features and functions of the switch, from a workstation on your network. The difference is that this management method encrypts the packets exchanged by your computer and the switch to protect your management sessions.
AT-9000 Gigabit Ethernet Switch Installation Guide SNMP 68 Refer to the AT-9000 Series Management Command Line Interface User’s Guide for instructions on how to configure the switch for SNMP management. The switch does not have any default SNMP community strings.
Chapter 5: Powering On the Switch Adding a Management IP Address You must assign the switch a management IP address to access the web user interface and to remotely manage the switch during a remote Telnet connection. Here are the requirements: The switch can have one management IPv4 address and one management IPv6 address. A management IP address must be assigned to a VLAN on the switch. It can be any VLAN, including the Default VLAN.
AT-9000 Gigabit Ethernet Switch Installation Guide Table 9. Example of Adding a Management Address awplus> enable Move to the Privileged Exec mode. awplus# configure terminal Move to the Global Configuration mode. awplus(config)# interface vlan1 Use the INTERFACE VLAN command to move to the VLAN Interface mode of the Default VLAN. awplus(config-if)# ip address 149.82.112.72/24 Assign the management IPv4 address to the switch using the IP ADDRESS command.
Chapter 6 Troubleshooting This chapter contains information about how to troubleshoot the switch in the event a problem occurs. Note If you are unable to resolve a problem after following the instructions in this chapter, contact Allied Telesis Technical Support for assistance. Refer to “Contacting Allied Telesis” on page 13 for contact information.
AT-9000 Gigabit Ethernet Switch Installation Guide 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: 72 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.
Chapter 6: Troubleshooting Twisted-Pair Port Link LED Is Off 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 switch is not set to the power-saving mode by pressing the ecoFriendly push-button on the front panel. Refer to “AT-9000 Series Gigabit Ethernet Switches” on page 19 for the ecoFriendly push-button location.
AT-9000 Gigabit Ethernet Switch Installation Guide 74 If a switch port is using Autonegotiation (the default setting) to set its speed and duplex mode settings, the end node connected to the port should also be using Autonegotiation 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 Autonegotiation.
Chapter 6: Troubleshooting Cannot Establish a Local (Out-of-Band) Management Session If you are unable to establish a local (out-of-band) management session with the switch through the terminal port on the front panel, do the following: Check that the RJ-45 connector of the serial management cable is securely connected to the Console port on the switch, and the DB9 connector is connected to the RS-232 port on the terminal or personal computer.
AT-9000 Gigabit Ethernet Switch Installation Guide All Port LEDs Are Off If all of the port LEDs are off, even though the ports are connected to active host devices, the switch may be operating in the low-power mode. To toggle on the LEDs, press the ecoFriendly button on the front panel of the switch.
Chapter 6: Troubleshooting Power Over Ethernet This section applies only to the AT-9000/12POE and AT-9000/28POE switches. Each RJ-45 port switch has two LEDs. The left LED provides port link and activity status, and the right LED provides PoE status information. The PoE LED is solid green when PoE is enabled. The PoE LED of a port that is not delivering power will be steady amber or off.
AT-9000 Gigabit Ethernet Switch Installation Guide Fiber Optic Transceivers This section applies only to the AT-9000/12POE, AT-9000/28, AT-9000/ 28POE, and AT-9000/28SP switches. The SFP LINK/ACT LEDs on the SFP ports are solid or flashing green when the fiber optic transceivers have links to end nodes.
Chapter 6: Troubleshooting Slow Performance Between Switch and Host Device If network performance between a twisted-pair port on the switch and a host device is slow, there might be a duplex mode mismatch between the port and the host device. This occurs when a twisted-pair port using Autonegotiation is connected to a device with a fixed duplex mode of full duplex.
