Page 22: Port Descriptions
Chapter 1: Overview Port Descriptions This section provides information on the following port types found on the AT-8500 Series switches: 10/100Base-TX This section applies to the AT-8524M, AT-8524POE, AT-8550GB, and AT-8550SP switches. Twisted Pair Ports Type of Connector The 10/100Base-TX twisted pair ports feature 8-pin RJ-45 connectors. - Page 23 AT-8500 Series Layer 2+ Fast Ethernet Switches Installation Guide Note In order for a switch port to successfully Auto-Negotiate its duplex mode with an end node, the end node should also be using Auto- Negotiation. Otherwise, a duplex mode mismatch can occur. A switch port using Auto-Negotiation will default to half-duplex if it detects that the end node is not using Auto-Negotiation.
-
Page 24: 10/100/1000Base-T Twisted Pair Ports
Chapter 1: Overview 10/100/ This section applies to Port 49R and Port 50R on the AT-8550GB and AT-8550SP switches. 1000Base-T Twisted Pair Type of Connector Ports The ports have 8-pin RJ-45 connectors. The ports use four pins when operating at 10 or 100 Mbps and all eight pins when operating at 1000 Mbps. -
Page 25: 100Base-Fx Fiber Optic Ports
Each fiber optic port has a maximum operating distance of two kilometers (1.25 miles) when operating in full-duplex mode and 412 meters (1,360 feet) when operating in half-duplex mode. AT-8500 Series Layer 2+ Fast Ethernet Switches Installation Guide Note The auto-MDI/MDI-X feature on a 10/100/1000Base-T port is functional only when the port is set to Auto-Negotiation. - Page 26 Chapter 1: Overview Type of Cable The fiber optic ports can use either 50/125 or 62.5/125 micron multimode fiber optic cable. Note Do not use single-mode fiber optic cable with these ports.

Page 27: Power Over Ethernet
AT-8500 Series Layer 2+ Fast Ethernet Switches Installation Guide Power Over Ethernet The following discussion applies only to the AT-8524POE switch. The twisted pair ports on the AT-8524POE 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. -
Page 28: Implementation
Chapter 1: Overview described in Table 3. . 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. -

MAC address assigned to them by the adapter manufacturers. An AT-8500 Series Fast Ethernet Switch has a MAC address table capable of storing up to 8,000 MAC addresses. The switch uses the table to store the MAC addresses of the network end nodes connected to the ports, along with the port number on which each address was learned. -
Page 41: Store And Forward
Naturally, an end node capable of operating in full-duplex can handle data much faster than an end node that can only operate in half-duplex mode. The twisted pair ports on the AT-8500 Series switches can operate in either half- or full-duplex mode. The twisted pair ports are IEEE 802.3u- compliant and will Auto-Negotiate the duplex mode setting for you. - Page 42 Chapter 1: Overview How a switch signals an end node to stop transmitting data differs depending on the speed and duplex mode of the end node and switch port. A twisted pair port operating at 100 Mbps port and half-duplex mode stops an end node from transmitting data by forcing a collision.

Chapter 1: Overview Ethernet Hubs Mixed Topology You can always combine topologies as well as build a larger network by connecting different switches together. If the switches are within 100 meters (328 feet) of each other, you can use the twisted pair ports. If the switches are further apart, then you can use fiber optic ports. -
