Chapter 1 Product Description The AT-GS916 and AT-GS924 switches are unmanaged, Layer 2 Gigabit Ethernet switches designed to simplify the task of creating or expanding an Ethernet, Fast Ethernet, or Gigabit Ethernet network.
Product Description Features AT-GS916 and AT-GS924 Gigabit Ethernet switches features include: 16 or 24 - 10/100/1000 Mbps twisted pair ports System and port LEDs Auto MDI/MDI-X Auto-Negotiation (IEEE 802.3u-compliant) 10/100 Mbps full or half-duplex, and 1000 Mbps full duplex Back pressure and flow control (IEEE 802.
AT-GS916 and AT-GS924 Gigabit Ethernet Switches Installation Guide Components Figure 1 illustrates the front panels of the AT-GS916 and AT-GS924 switches.
Product Description Hardware Feature Description The following sections describe hardware features of the AT-GS916 and AT-GS924 Gigabit Ethernet switches: System and Port LEDs Twisted Pair Ports AC Power Connector Twisted Pair Ports The AT-GS916 Gigabit Ethernet switch features 16 twisted pair ports, and the AT-GS924 Gigabit Ethernet switch features 24 twisted pair ports. Type of Connector The twisted pair ports feature 8-pin RJ-45 connectors.
AT-GS916 and AT-GS924 Gigabit Ethernet Switches Installation Guide Auto MDI/MDI-X All of the twisted pair ports on the switch are auto-MDI and IEEE 802.3ab-compatible. When a port's speed and duplex mode are set through Auto-Negotiation, the port uses the auto-MDI feature to automatically configure itself as MDI or MDI-X when connected to an end-node. Consequently, you can use either a straight-through or crossover twisted pair cable when connecting any network device to a port.
Product Description Table 1 System and Port LEDs LED State Description ACT Green A valid link has been established between the port and the end-node. Flashing Green The port is transmitting and/or receiving data packets. OFF There is no link established between the port and the end-node. Green The port is operating in full-duplex mode. OFF The port is operating in half-duplex mode.
AT-GS916 and AT-GS924 Gigabit Ethernet Switches Installation Guide A Few 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.
Product Description If the switch receives a packet with a destination address that is on the same port on which the packet was received, it discards the packet without forwarding it on to any port. Since both the source end-node and the destination end-node for the packet are located on the same port on the switch, there is no reason for the switch to forward the packet. Duplex Mode Duplex mode refers to how an end-node receives and transmits data.
AT-GS916 and AT-GS924 Gigabit Ethernet Switches Installation Guide A port operating in full-duplex mode uses PAUSE frames, as specified in the IEEE 802.3x standard, to stop the transmission of data from an endnode. Whenever the switch wants an end-node to stop transmitting data, it issues this frame. The frame instructs the end-node to cease transmission for a period of time specified within the frame. The switch continues to issue PAUSE frames until it is ready again to receive data from the end-node.
Product Description Network Topologies This section illustrates two network topologies that you can create with the AT-GS916 Gigabit Ethernet 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 switch.
AT-GS916 and AT-GS924 Gigabit Ethernet Switches Installation Guide Collapsed Backbone In the topology illustrated in Figure 5, an AT-GS916 switch connects Fast Ethernet switches that have Gigabit Ethernet uplinks. This type of topology is often referred to as a collapsed backbone topology.
Chapter 2 Installation This chapter contains the following sections: ”Reviewing Safety Precautions” on page 21 ”Selecting a Site for the Switch” on page 22 ”Planning the Installation” on page 23 ”Unpacking the Switch” on page 24 ”Installing the Power Cord Retaining Clip” on page 25 ”Installing the Switch in a Rack” on page 27 ”Cabling the Switch” on page 29 ”Powering On the Switch” on page 30 ”Warranty Registration” on page 32 20
AT-GS916 and AT-GS924 Gigabit Ethernet Switches Installation Guide Reviewing Safety Precautions Please review the following safety precautions before you begin to install the switch or any of its components. Refer to ”” on page 39 for translated safety statements in your language. Warning Electric Shock Hazard: To prevent electric shock, do not remove the cover. There are no user-serviceable parts inside. The unit contains hazardous voltages and should only be opened by a trained and qualified technician.
Installation Selecting a Site for the Switch Observe the following requirements when choosing a site for your switch: 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.
