Model Naming Conventions of the Fiber Optic 8100S Series Switches Convention Definition 1 This is the product name. 2 The letter “S” indicates that the model is stackable. 3 This is the number of 100Base-FX fiber optic ports. 4 The letter “F” signifies fiber optic. 5 This is the number of 10/100Base-TX ports.
Chapter 1: Overview 10/100Base-TX Twisted Pair Ports The switches have 8 or 24 10/100Base-TX ports. Speed Duplex Mode 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. 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.
Stack Installation Guide for 8100S Series Switches Maximum Distance The ports have a maximum operating distance of 100 meters (328 feet). Power Over Ethernet The 10/100Base-TX ports on the AT-8100S/24POE Switch supports 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 switch supports PoE (IEEE 802.3af) and PoE+ (IEEE 802.3at). For background information, refer to “Power Over Ethernet” on page 35.
Chapter 1: Overview 10/100/1000Base-T Twisted Pair Ports The switches have two 10/100/1000Base-T ports. These ports are paired with SFP slots to form combo ports. 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 Auto-Negotiation to function at 1000 Mbps. They are not compatible with devices that are not IEEE 802.3u compliant.
Stack Installation Guide for 8100S Series Switches Maximum Distance The ports have a maximum operating distance of 100 meters (328 feet). Power Over Ethernet The 10/100/1000Base-T ports on the AT-8100S/24POE Switch does not support PoE. Cable Requirements The cable requirements of the ports are given in Table 7. Table 7.
Chapter 1: Overview SFP Slots The switches have two slots for 100Mbps 100Base-FX or 1000Mbps 1000Base-SX/LX fiber optic transceivers. You may add transceivers to connect the switches to other network devices over large distances, build a high-speed backbone network between network devices, or connect high-speed devices, such as servers, to your network. The switches support a variety of short and long distance, 100 and 1000 Mbps fiber optic SFP modules.
Stack Installation Guide for 8100S Series Switches Power Over Ethernet The AT-8100S/24POE Switch features 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. 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.
Chapter 1: Overview Table 9. IEEE Powered Device Classes Class Power Budget Maximum Power Output from a Switch Port Power Ranges of the PDs 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 25.5W The AT-8100S/24POE Switch has 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 PoE switch has two power supplies.
Stack Installation Guide for 8100S Series Switches Port Prioritization If the power requirements of the powered devices exceed the switch’s power budget, the switch will deny 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.
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.
Stack Installation Guide for 8100S Series Switches S1 and S2 Stacking Ports The switch may be used as a stand-alone unit or as part of a stack in which multiple units are interconnected via the S1 and S2 stacking ports on the front panels.
Chapter 1: Overview eco-friendly Button You may turn off the port LEDs to conserve electricity when you are not monitoring the switch. The LEDs may be toggled with the eco-friendly button on the front panel of the switch or the ECOFRIENDLY LED and NO ECOFRIENDLY LED commands in the Global Configuration mode of the command line interface. Toggling the LEDs on and off does not interfere with the network operations of the device. The Stack ID LED is always on.
Stack Installation Guide for 8100S Series Switches LEDs Here are the descriptions of the switch’s LEDs. 10/100Base-TX Twisted Pair Port LEDs The 10/100Base-TX twisted pair ports have link/activity and duplex mode LEDs. Link/Activity LED Duplex Mode LED Link/Activity LED Duplex Mode LED Figure 10. 10/100Base-TX Port LEDs The LEDs are described in this table.

Stacking Port LED LED LINK/ACT State Description Off The stacking port is not connected to another switch or has not established a link. Solid green The stacking port has established a link with a stacking port on another switch.
Chapter 1: Overview Stack ID LED The Stack ID LED displays the ID number of the switch. A stand-alone switch should have the ID number 0. Switches connected with the stacking ports to form a virtual stack must have unique numbers. Chapter 5, “Assigning the Stack ID Numbers and Cabling the Stacking Ports” on page 79 has the procedure for verifying and, if necessary, changing the ID number of the switch. Stack ID LED Figure 15.
Stack Installation Guide for 8100S Series Switches 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 must use the management cable included with the switch.
Chapter 1: Overview Power Supplies The switches are powered by two internal AC power supplies, except for the AT-8100S/24C Switch, which has one power supply. The supplies are not field-replaceable and each has a separate AC connector on the back panels. Only one power supply is active at a time in non-PoE switches. 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.
Stack Installation Guide for 8100S Series Switches Power Connectors The 8100S Series switches have two AC or DC power supply sockets on the back panels, except for the AT-8100S/24C Switch, which has just one AC power supply socket. AC switches are powered on or off by connecting or disconnecting the power cords. DC switches are powered on or off by energizing or de-energizing the DC circuit breakers to which the switches are connected in the wiring closet.

Chapter 2 Stacking Overview This chapter contains the following sections: “Stacking Guidelines” on page 52 “Master Switch” on page 54 “Stacking Port Topologies” on page 55 “Active Boot Configuration File” on page 57 “Initialization Process” on page 59 51
Chapter 2: Stacking Overview Stacking Guidelines A stack is a group 8100S Series switches linked together with the S1 and S2 stacking ports to function as a unified Fast Ethernet switch. They synchronize their actions so that network operations, such as spanning tree protocols, virtual LANs, and static port trunks, span across all of the Fast Ethernet ports.
Stack Installation Guide for 8100S Series Switches The other units are referred to as member switches. The stacking feature described in this guide is unrelated to the enhanced stacking feature described in the AT-8100 Series AlliedWare Plus Command Line Interface User’s Guide. They are completely different features.
Chapter 2: Stacking Overview Master Switch A stack must have a master switch to coordinate and monitor stack operations. It verifies that the switches are using the same version of management software, that no two switches have the same ID number, and that the stacking ports are cabled correctly. The selection of the master switch is based on the ID numbers. The master switch is the switch with the lowest ID number of all the switches in the stack.
Stack Installation Guide for 8100S Series Switches Stacking Port Topologies The switches are connected together with the S1 and S2 ports in the management panels, and the stacking cables that come with the units. There are two wiring configurations. The first topology is called the duplexchain topology. This topology connects the switches with a single pathway. A stacking port on one switch is connected to a stacking port in the next switch, which is connected to the next switch, and so on.
Chapter 2: Stacking Overview Duplex-chain Configuration Duplex-ring Configuration Figure 16 Duplex-chain and Duplex-ring Configurations 56
Stack Installation Guide for 8100S Series Switches Active Boot Configuration File The master switch stores the settings of the entire stack in a file in its file system. This file is referred to as the active boot configuration file. The switch updates the file with the most recent parameter changes whenever you issue the WRITE or COPY RUNNING-CONFIG STARTUP-CONFIG command. The switch comes with two identical boot configuration files, called BOOT.CFG and QSTACK.CFG.
Chapter 2: Stacking Overview instructs the other switches to designate that filename as the active boot configuration file so that they use that file if they become the master switch. Here is an example of how the process works. Let’s assume your stack has three switches, assigned the ID numbers 1 to 3. The switch with the ID number 1 is the master switch because it has the lowest ID number of all the switches in the stack.
Stack Installation Guide for 8100S Series Switches Initialization Process The switches of the stack synchronize their operations in a five phase process when they are powered on or reset, and prior to forwarding network traffic from their ports. In the first three phases the switches initialize their management software and features. These phases take a total of approximately 40 seconds. In the fourth phase, called the discovery process.

Stack Installation Guide for 8100S Series Switches Verifying the Installation To verify the installation of the stack, perform the following procedure: 1. Establish a local or Telnet management session on the master switch of the stack. For instructions, refer to “Starting a Local Management Session” on page 82 or “Starting a Telnet Management Session” on page 83.
Chapter 6: Powering On and Verifying the Stack Examine the stack ID LEDs to verify that each switch has been assigned a unique ID number, in the range of 1 to 8. If there are switches with duplicate numbers, power off the stack and perform the procedures in Chapter 5, “Assigning the Stack ID Numbers and Cabling the Stacking Ports” on page 79. (The stack ID number must be set while the switch is functioning as a stand-alone unit.
Chapter 7 Cabling the Network Ports This chapter contains the following procedures: “Cabling the Twisted Pair and Fiber Optic Ports” on page 104 “Installing Optional SFP Transceivers” on page 106 “Managing the Stack” on page 110 103
Chapter 7: Cabling the Network Ports Cabling the Twisted Pair and Fiber Optic Ports This section contains the guidelines to cabling the twisted pair and fiber optic ports. Twisted Pair Ports 104 Here are the guidelines to cabling the 10/100Base-TX and 10/100/ 1000Base-T twisted pair ports: The cable specifications for the 10/100Base-TX and 10/100/ 1000Base-T twisted pair ports are listed in Table 6 on page 31 and Table 7 on page 33, respectively.
Stack Installation Guide for 8100S Series Switches Fiber Optic Ports General Guidelines 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 that also support Auto-Negotiation for duplex modes.
Chapter 7: Cabling the Network Ports Installing Optional SFP Transceivers Review the following guidelines before installing optional SFP transceivers in the switch: The SFP slots are part of combo ports, with 10/100/1000Base-T ports. For operational information, refer to “SFP Slots” on page 34. SFP transceivers can be hot-swapped while the switch is powered on. However, you should always disconnect the fiber optic cables first before removing a transceiver.
Stack Installation Guide for 8100S Series Switches Figure 45. 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 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. 4.

Chapter 7: Cabling the Network Ports Managing the Stack You may manage an 8100S Series stack with these methods and tools: Local Management Local management Telnet client Secure shell client Web browser SNMPv1, v2C, v3 You may manage a stack through the Console port on the master switch. This is called local management or out-of-band management because the management sessions are not conducted over your network.
Stack Installation Guide for 8100S Series Switches address 169.254.1.1. Refer to your computer’s documentation for instructions on how to set the IP address. Note Your computer automatically defaults to an 169.254.n.n address if it is running a DHCP client and does not receive a response from a DHCP server. To have a DHCP client assign the address, disconnect your computer from your network, power it on, wait for the DHCP client to generate the IP address 169.254.n.
Chapter 7: Cabling the Network Ports Web Browser Management Yet another way to remotely manage a stack is with a web browser. A special web browser interface, featuring both non-secure (HTTP) and secure (HTTPS) operation, lets you monitor and configure many of the switch’s features from a series of windows. The interface, however, may only be used to configure a subset of the features.
Stack Installation Guide for 8100S Series Switches The slot ID value, which is used to specify slot numbers in a multi-module chassis, does not apply to 8100S Series switches and should always be 0. The third value is a port number on the switch. You may specify one port number in a PORT parameter, but you may specify more than one PORT parameter in many of the commands that support the parameter. Here is an example of the PORT parameter.
Chapter 7: Cabling the Network Ports 114
Chapter 8 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. Refer to “Contacting Allied Telesis” on page 15. Problem 1: The Stack 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.
Chapter 8: Troubleshooting Problem 3: The stack ID LEDs on the switches of the stack are flashing the ID numbers and the letter “H” every few seconds. Solution: This is normal for the LEDs when the switches are operating in a stack configuration. Problem 4: All of the port LEDs are off even though the ports are connected to active network devices. Solution: The LEDs may have been turned off. To toggle on the LEDs, press the eco-friendly button on the front panel.
Stack Installation Guide for 8100S Series Switches Check that the SFP module is fully inserted in the slot. Verify that the operating specifications of the fiber optic ports on the SFP transceiver and the remote network device are compatible. Verify that the correct type of fiber optic cabling is being used. Verify that the port is connected to the correct fiber optic cable. This is to eliminate the possibility that the port is connected to the wrong remote network device.
Chapter 8: Troubleshooting 118
Chapter 9 Adding or Removing Switches The procedures in this chapter explain how to add or remove switches from the stack.
Chapter 9: Adding or Removing Switches Removing or Replacing the Master Switch This procedure is divided into the following phases: Phase 1: “Uploading the Active Configuration File” on page 121 Phase 2: “Removing the Current Master Switch” on page 122 Phase 3: “Configuring the New Master Switch” on page 125 Phase 4: “Connecting the New Master Switch to the Stack” on page 127 The procedures should be performed in the order presented here.
Stack Installation Guide for 8100S Series Switches Uploading the Active Configuration File The first step to replacing the master switch of the stack is to upload the active boot configuration file, which contains the configuration settings of the stack, to your workstation or, alternatively, to a TFTP server. You’ll download the file to the new switch later in these procedures.
Chapter 9: Adding or Removing Switches sure to include the .CFG extension. This example of the command uploads a configuration file called stack_eng.cfg: awplus# copy stack_eng.cfg zmodem 4. After you enter the command, begin the file transfer using your terminal emulator program. The upload, which takes only a few seconds, is completed when the command prompt is displayed again. 5. Go to the next procedure.
Stack Installation Guide for 8100S Series Switches Note If the switch has SFP modules, perform steps 3 to 7. Otherwise, go to step 8. 3. Label and remove the fiber optic cable from the SFP module. Figure 53. Removing the Fiber Optic Cable from the SFP Module 4. Install the dust cover on the fiber optic port. Figure 54.
Chapter 9: Adding or Removing Switches 5. Remove and label the module from the switch, as shown in Figure 55. Figure 55. Removing the SFP Module 6. Install the dust cover in the SFP slot, as shown in Figure 56. Figure 56. Installing the Dust Cover in the SFP Slot 7. If the switch has two SFP modules, repeat steps 3 to 6 to remove the second module. 8. Label and disconnect the stacking cables from the stacking ports on the front panel of the switch, as shown in Figure 57 on page 125.
Stack Installation Guide for 8100S Series Switches Figure 57. Removing the Stacking Cables 9. Remove the switch from the equipment rack. 10. Go to the next procedure. Configuring the New Master Switch With the master switch removed from the equipment rack, you are ready to install the new master switch by configuring its stack ID number and downloading the configuration file. These steps must be performed before the switch is connected to the stack.
Chapter 9: Adding or Removing Switches 5. Assign the switch its stack ID number. For instructions, refer to “Changing the Stack ID Number” on page 85. 6. After configuring the stack ID number, reestablish your local management session. 7. Download onto the switch the configuration file you uploaded earlier from the previous master switch or from one of the member switches.
Stack Installation Guide for 8100S Series Switches 11. Use the EXIT command to return to the Privileged Exec mode and Issue the SHOW CONFIG command to verify that the downloaded configuration file is the new active configuration file. The “Current boot config” field should contain the name of the configuration file you designated in step 9. awplus(config)# exit awplus# show boot 12. Power off the new master switch. 13. Go to the next procedure.
Chapter 9: Adding or Removing Switches Adding a New Member Switch Here are the guidelines to adding a new member switch to a stack: You have to power off a stack to add new member switches. To minimize the disruption to network users, you should add new switches to a stack during non-business hours. Adding a new member switch to an active stack is not recommended because it may cause unpredictable results.
Stack Installation Guide for 8100S Series Switches c. If the “Current boot config” field is displaying the filename BOOT.CFG, perform this command to create an archive copy of it. Otherwise, go to step 2. awplus# copy boot.cfg archive_boot.cfg d. Log off by entering the EXIT command. 2. Power off the switch. 3. Label and disconnect all of the network cables from the ports. 4. Install the switch in the same equipment rack as the stack.
Chapter 9: Adding or Removing Switches Removing a Member Switch Here are the guidelines to removing a member switch from the stack: You may leave the stack powered on if it is cabled in the duplexring topology, or if it is cabled in the duplex-chain topology and the switch to be removed is located at the end of the stack. You should power off the stack if it is wired in the duplex-chain topology and the member switch to be removed is located between other switches.
