Chapter 1: Overview 10/100/1000Base-T Twisted Pair Port The 10/100/1000Base-T twisted pair port is described below: Type of Connector The twisted pair port has an 8-pin RJ-45 connector. The port uses four pins when operating at 10 or 100 Mbps and all eight pins when operating at 1000 Mbps. For the port pinout details, refer to “10/100/1000Base-T Port Pinouts” on page 60. Port Speed The twisted pair port can operate at 10, 100, or 1000 Mbps. IEEE 802.
AT-PC2002/POE Media Converter Installation Guide Type of Cabling Table 1 lists the cable specifications for the twisted pair port. Table 1. Twisted Pair Cabling and Distances Speed Auto MDI/MDI-X Cable Type Maximum Operating Distance 10 Mbps Standard TIA/EIA 568-B-compliant Category 3 or better shielded or unshielded cabling with 100 ohm impedance and a frequency of 16 MHz.
Chapter 1: Overview SFP Module Slot The SFP slot can support one 100Base-FX or 1000Base-X SFP module. For the list of supported modules, contact your Allied Telesis sales representative.
AT-PC2002/POE Media Converter Installation Guide Operating Modes The AT-PC2002/POE Media Converter supports these operating modes: Link Test Mode “Link Test Mode,” next “MissingLink Mode” on page 21 “Smart MissingLink Mode” on page 22 Contrary to its name, the Link Test operating mode is not a diagnostic utility. Rather, this mode simply reflects the states of the links on the ports on the LinK LEDs.
Chapter 1: Overview connected to port 1, the fiber optic port, on the media converter, while Switch 2, the local device, is connected to port 2, the twisted pair port. If the link to Switch 1 is lost, the line card disables the transmitter on port 2 to signal Switch 2 of the loss of the link to Switch 1.
AT-PC2002/POE Media Converter Installation Guide respond by pulsing the transmitter on the twisted pair port and flashing the port’s Link LED about once a second to signal that the failure originated on the fiber optic port. When the connection is reestablished on the fiber optic port, the twisted pair port would automatically resume normal operations to permit the two ports to forward traffic again. The operating mode functions the same if the failure starts on the twisted pair port.
Chapter 1: Overview Power over Ethernet The twisted pair port on the AT-PC2002/POE Media Converter features Power over Ethernet (PoE), which is a mechanism for supplying power to a network device over the same twisted pair cable that is used to carry the network traffic. A device that receives its power over an Ethernet cable is called a powered device (PD). Examples include wireless access points, voice over Internet Protocol (VoIP) telephones, web cams, and unmanaged Ethernet switches.
