The port uses four pins when operating at 10 or 100 Mbps. For the port pinout details, refer to Figure 17 , “RJ-45 Connector and Port Pin Layout” on page 54. Port Speed The 10/100Base-TX twisted pair port can operate at 10 or 100 Mbps.
AT-PC232/POE Media Converter Installation Guide Type of Cabling For 10 Mbps, the port requires Category 3 or better 100 ohm shielded or unshielded twisted pair cabling. For 100 Mbps operation, the port requires Category 5 or Enhanced Category 5 (5E) 100 ohm shielded or unshielded twisted pair cabling. Auto MDI/MDI-X The 10/100Base-TX twisted pair port on the AT-PC232/POE Media Converter is auto-MDI/MDI-X and IEEE 802.3ab-compatible.
Chapter 1: Overview 100Base-FX Fiber Optic Port The AT-PC232/POE Media Converter features a single fiber optic port. Type of Connector The fiber optic port features a duplex SC connector. Port Speed The fiber optic port has a fixed operating speed of 100 Mbps. The endnode connected to the port must also be able to operate at 100 Mbps. This speed cannot be changed. Duplex Mode Maximum Distance Type of Cable 20 The fiber optic port can operate in either full-duplex or half-duplex mode.
AT-PC232/POE Media Converter Installation Guide Operating Modes The AT-PC232/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. Instead, it uses the Link LEDs to display the current states of the ports.
Chapter 1: Overview switches, one local and the other remote. Switch 1, the remote switch, is 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-PC232/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-PC232/POE Media Converter features 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. This feature can simplify network installation and maintenance by allowing you to use the switch as a central power source for other network devices. A device that receives its power over an Ethernet cable is called a powered device (PD).
