Chapter 1

Overview

The AT-PC2002/POE Media Converter is a simple and reliable way to connect Fast or Gigabit Ethernet devices across large geographical distances with fiber optic cable. The unit has one 10/100/1000Base-T twisted pair port for a local connection and one slot for a fiber optic 100Base-FX or 1000Base-X SFP module. The product features Power over Ethernet (PoE) on the twisted pair port for support of a Powered Device (PD), such as a wireless access point or a Voice over Internet Protocol (VoIP) telephone.
This unmanaged product is suitable for the central office or a remote site and can be installed on a table or a wall. LEDs on the front panel display the general status of the unit and the ports, and DIP switches on the back panel let you configure the port settings.
The product features low latency to minimize the impact on network performance along with cyclic redundancy check (CRC) detection to prevent the propagation of incomplete or fragmented packets on your network.

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 802.3u-

compliant, the unit can set the speed of the port automatically with Auto­Negotiation or you can set the speed manually with the DIP switches on the back panel.
Note
The twisted pair port has to be set to Auto-Negotiation to operate at 1000 Mbps.

Duplex Mode The port can operate in either half- or full-duplex mode. If Auto-Negotiation

is activated on the port, the duplex mode is set automatically. If Auto­Negotiation is disabled, you set the duplex mode manually using the DIP switches.
Note
In order for the media converter to successfully Auto-Negotiate the duplex mode of the twisted pair port with an end-node, the link partner should also be using Auto-Negotiation. Otherwise, a duplex mode mismatch can occur. While configured for Auto-Negotiation, port will default to half-duplex if it detects that its link partner is not using Auto-Negotiation. This will result in a mismatch if the end-node is operating at a fixed duplex mode of full-duplex.

Maximum
Distance
The 10/100/1000Base-T twisted pair port has a maximum operating distance of 100 meters (328 feet).

The wiring configuration of the twisted pair port is set automatically with auto-MDI/MDI-X. Consequently, you can use a straight-through twisted pair cable to connect any type of Ethernet network device to the port. The auto-MDI/MDI-X feature is always active, even when the Auto- Negotiation feature is turned off and the speed and duplex mode on the port are set manually.

AT-PC2002/POE Media Converter Installation Guide

Operating Modes

The AT-PC2002/POE Media Converter supports these operating modes:
“Link Test Mode,” next
“MissingLink Mode” on page 21
“Smart MissingLink Mode” on page 22

Link Test Mode 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. When the media converter is operating in this mode, a port’s Link LED will be on when the port has a link to a network device and it will be off when the port does not have a link to a network device.
This operating mode is typically used when the network devices connected to the ports of the media converter cannot take advantage of the features of the MissingLink mode, or when you want to use the Link LEDs to troubleshoot a network problem. This operating mode is also useful after the installation of the media converter to verify whether or not the ports on the unit have established links to their network devices.
MissingLink
Mode
The MissingLink mode allows the two ports on the media converter to share their “link” status with each other. If one of the ports is unable to establish a link with its network device or loses the link, the operating mode disables the transmitter on the other port. This action notifies the network device connected to the port that there is a loss of the link on the other port. Without the MissingLink mode, a network device connected to a port would be unaware of a loss of a link on the companion port, because its link to the media converter would be unaffected. To explain it another way, the MissingLink mode will not allow a port to form a link with its network device unless the other port on the media converter can also establish a link with its device.
When the link is reestablished on a port, the MissingLink mode automatically reactivates the transmitter on the other port so that the two port can again forward traffic to each other.
This operating mode is intended to take advantage of the fact that some network devices, such as managed Fast Ethernet switches, can respond to the loss of a link on a port by performing a specific action. For example, the network device might send a trap to a network management station, and so alert the network administrator of the problem. Or, if the device is running a spanning tree protocol, it might seek a redundant path to a disconnected node.
Here is an example of how the MissingLink mode works. Assume that the two ports on a media converter are connected to two Fast Ethernet switches, one local and the other remote. Switch 1, the remote switch, is
