The 10/100Base-TX twisted pair port is described below:

The 10/100Base-TX twisted pair port on AT-PC232/POE Media Converter features an 8-pin RJ-45 connector. 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.

The 10/100Base-TX twisted pair port can operate at 10 or 100 Mbps. The speed is set automatically through Auto-Negotiation or you can set the speed manually via the DIP switches located on the back of the unit. With Auto-Negotiation, the speed of the port is set automatically by the converter after it determines the speed of the end-node connected to the port. Auto-Negotiation is designed to ensure that the port on the converter and the end-node are operating at the same speed and that they are communicating at the highest possible common speed of the devices.

Duplex mode refers to how an end-node receives and transmits data. If an end-node can receive or transmit data, but not both simultaneously, the end-node is operating in what is referred to as half-duplex mode. If an end-node can both receive and transmit data simultaneously, the end- node is said to be operating in full-duplex mode. 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 port is IEEE 802.3u-compliant and will Auto-Negotiate the duplex mode setting. It can be manually reconfigured to either full or half- duplex mode via the DIP switches located on the back of the unit when the Auto-Negotiate switch is in the OFF position.

Note

In order for a converter port to successfully Auto-Negotiate its duplex mode 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, a converter 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.

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

AT-PC232/POE specifications

Allied Telesis AT-PC232/POE is a versatile and robust power-over-Ethernet (PoE) switch that effectively meets the needs of small to medium-sized networks. Designed for user-friendly operation and scalability, this switch caters to the increasing demand for power and data connectivity in various environments, from small offices to larger enterprise applications.

One of the main features of the AT-PC232/POE is its capability to deliver both data and electrical power over a single Ethernet cable. This functionality simplifies installations of network devices such as IP cameras, VoIP phones, and wireless access points, reducing cabling costs and improving site aesthetics. The switch can supply up to 15.4 watts of power per port, adhering to the IEEE 802.3af PoE standard. This enables straightforward connection to devices without needing additional power sources, making it a convenient choice for businesses looking to streamline their operational efficiency.

In terms of design, the AT-PC232/POE is compact and rack-mountable, allowing for efficient use of space in server rooms and network closets. Its fanless operation ensures quiet performance, making it suitable for noise-sensitive environments. The switch is also equipped with LED indicators that provide at-a-glance updates on power status, network activity, and port statistics.

The AT-PC232/POE utilizes advanced networking technologies such as VLAN (Virtual Local Area Network) support and QoS (Quality of Service). VLAN support allows network administrators to segment network traffic for better performance and security, while QoS capabilities prioritize critical data packets, ensuring that important applications such as video conferencing and VoIP operate smoothly without interruption.

Another significant characteristic of this switch is its management capabilities. Allied Telesis provides a web-based graphical user interface (GUI) for easy configuration and monitoring, allowing administrators to quickly set up networks and troubleshoot issues. Security features such as port security and access control lists help prevent unauthorized access and ensure that the network remains secure.

In summary, the Allied Telesis AT-PC232/POE switch combines efficient power delivery with sophisticated networking features, making it an excellent choice for businesses looking to enhance their network infrastructure. Its compact design, ease of use, and management capabilities position it as a reliable solution for modern networking demands.
