Chapter 1: Overview Ports The AT-GS950/8 switch features eight twisted pair ports and two SFP ports. See the following sections for descriptions of the ports. Twisted Pair Ports The twisted pair ports feature 8-pin RJ-45 copper connectors. (For the port pinouts, refer to “Connectors and Port Pinouts” on page 50.) The ports are 10Base-T, 100Base-TX, and 1000Base-T compliant and are capable of 10 megabits per second (Mbps), 100 Mbps, and 1000 Mbps speeds. In addition, the twisted pair ports are IEEE 802.

The system and port LEDs are show in Figure 2 and described in Table 2 and Table 3. 914 System (Power) LED Port LEDs Figure 2. System and Port LEDs Table 2. System LED LED State Description POWER Off The switch is not receiving power. On The switch is receiving power. Table 3.
Chapter 1: Overview The SFP LEDs are shown in Figure 3 and described in Table 4. 930 Figure 3. SFP LEDs. Table 4. SFP Port LEDs LED State Description In Use (port 7) Off The port has not established a link with an end node. Blinking Green The port is transmitting or receiving data. Green A valid link has been established on the port. Off The port has not established a link with an end node. Blinking Green The port is transmitting or receiving data.
AT-GS950/8 Gigabit Ethernet WebSmart Switch Installation Guide Power Supply The switch has an internal power supply with a single AC power connector on the back panel. This connector features autoswitch AC inputs. To power the switch on or off, connect or disconnect the power cord provided with the switch. Note For the power requirements, refer to “Power Specifications” on page 49.
Chapter 1: Overview Ethernet Switching Basics An Ethernet switch interconnects network devices, such as workstations, printers, routers, and other Ethernet switches, so that they can communicate with each other by sending and receiving Ethernet frames. MAC Address Table Every hardware device on your network has a unique MAC address. This address is assigned to the device by the device’s manufacturer.
AT-GS950/8 Gigabit Ethernet WebSmart Switch Installation Guide Duplex Mode The term duplex mode refers to how an end node receives and transmits data. If an end node can receive or transmit data, but not both simultaneously, the end node is operating in half-duplex mode. If an end node can both receive and transmit data simultaneously, the end node is operating in full-duplex mode.
Chapter 1: Overview Back Pressure and Flow Control To maintain the orderly movement of data between the end nodes, an Ethernet switch may periodically need to signal an end node to stop sending data. This can occur under several circumstances. For example, if two end nodes are operating at different speeds, the switch, while transferring data between the end nodes, instructs the faster end node to stop transmitting data to allow the slower end node to catch up.
AT-GS950/8 Gigabit Ethernet WebSmart Switch Installation Guide Network Topologies This section describes two network topologies that you can create with the AT-GS950/8 switch: a power workgroup and collapsed backbone. Both types of topologies are described below. Power Workgroup Topology The topology shown in Figure 4 is commonly referred to as a power workgroup topology. Each workstation or end node is connected directly to a port on the AT-GS950/8 switch.

Chapter 2: Installation Reviewing Safety Precautions Please review the following safety precautions before you begin to install the chassis or any of its components. Note The indicates that a translation of the safety statement is available in a PDF document titled “Translated Safety Statements” on the Allied Telesis website at www.alliedtelesis.com and also on the documentation CD shipped with this product. Warning: To prevent electric shock, do not remove the cover. No user-serviceable parts inside.
AT-GS950/8 Gigabit Ethernet WebSmart Switch Installation Guide Circuit Overloading: Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
Chapter 2: Installation Selecting a Site for the Switch Observe the following requirements when choosing a site for your switch: 30 If you plan to install the switch in an equipment rack, ensure that the rack is safely secured and 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 are installing the switch on a table, ensure that the table is level and secure.
AT-GS950/8 Gigabit Ethernet WebSmart Switch Installation Guide Cabling Table 5 contains the cabling specifications for the twisted pair ports. Table 5.
Chapter 2: Installation Unpacking the Switch To unpack the switch, perform the following procedure: 1. Remove all components from the shipping package. Note Store the packaging material in a safe location. You must use the original shipping material if you need to return the unit to Allied Telesis. 2. Place the switch on a level, secure surface. 3.
AT-GS950/8 Gigabit Ethernet WebSmart Switch Installation Guide Installing the Switch on a Desktop To install the switch on a desktop, perform the following procedure: 1. Remove all equipment from the package and store the packaging material in a safe place. 2. Turn the switch over and attach the four rubber feet to the bottom of the switch as shown in Figure 6. 917 Figure 6. Attaching the Rubber Feet 3.
Chapter 2: Installation Mounting the Switch on a Wall To mount the AT-GS950/8 switch on a wall, perform the following procedure: 1. If the rubber feet are attached, turn over the switch and remove the rubber feet using a flat-head screwdriver. 2. Select a wall location for the device. 3. Choose one of the following: For drywall installation, drill two 1/8-inch holes that are 5 3/8 inches apart. Insert the plastic anchors. Tap the anchors flush with the wall.
AT-GS950/8 Gigabit Ethernet WebSmart Switch Installation Guide The front of the switch faces the floor as shown in Figure 8. 921 Figure 8. Positioning the Switch (Switch Faces Down) To cable and power on the switch, see “Cabling and Powering On the Switch” on page 40.
Chapter 2: Installation Installing the Switch in a Rack To install the AT-GS950/8 switch in a rack, perform the following procedure: 1. If rubber feet are attached, remove them using a flat-head screwdriver. 2. Install a rack-mount bracket on one side of the switch using a Phillips screwdriver and four of the rack-mount screws included with the switch. There are two ways to attach the brackets to the chassis. Attach the brackets so the switch is flush with the front of the rack as shown in Figure 9.
AT-GS950/8 Gigabit Ethernet WebSmart Switch Installation Guide Figure 11 shows how to mount the switch so that it is flush with the rack, and Figure 12 shows to mount the switch so that it extends in front of the rack. 919 Figure 11. Mounting the Switch on a Rack (Switch is Flush with Rack) 932 Figure 12. Mounting the Switch on a Rack (Switch Extends From Rack) 5. Repeat step 4 to attach the switch to the other side of the rack. To cable the switch, see “Cabling and Powering On the Switch” on page 40.
Chapter 2: Installation Installing an Optional SFP Transceiver The AT-GS950/8 switch has two SFP uplink ports on the front of the switch. To install an SFP transceiver, perform the following procedure: Note You must install the SFP transceiver before you connect cables to it. Note The transceiver can be hot-swapped; you do not need to power off the switch to install a transceiver. However, always remove the cables before removing the transceiver. 1.
AT-GS950/8 Gigabit Ethernet WebSmart Switch Installation Guide 4. Slide the SFP transceiver into an SFP slot on the switch, as shown in Figure 14. 923 Figure 14. Inserting the SFP Transceiver 5. Repeat steps 2 through 4 if you are installing another SFP transceiver. Note SFP transceivers are dust sensitive. When a fiber optic cable is not installed, or when you store the SFP transceiver, keep the plug in the optical bores. When you do remove the plug, keep it for future use.
