Twisted Pair Ports

Uplink Combo Ports

The AT-FS750/24POE Fast Ethernet Smart switch features 24 twisted pair ports and two uplink combo ports.

The twisted pair ports feature 8-pin RJ-45 connectors. (For the port pinouts, refer to “Connectors and Port Pinouts” on page 52.)

The ports on the AT-FS750/24POE Fast Ethernet Smart switch are 10Base-T and 100Base-TX compliant and are capable of 10 megabits per second (Mbps) and 100 Mbps speeds.

The ports are IEEE 802.3u Auto-Negotiation compliant. With Auto- Negotiation, the switch automatically matches the highest possible common speed between each switch port and each end node. For example, if an end node is capable of only 10 Mbps, the switch sets the port connected to the end node to 10 Mbps.

Each twisted pair port on the switch can operate in either half- or full- duplex mode. The twisted pair ports are IEEE 802.3u-compliant and Auto- Negotiate the duplex mode setting.

Note

In order for the switch to set the duplex mode for each port correctly, the end nodes that you connect to the switch ports should also use Auto-Negotiation. Otherwise, a duplex mode mismatch can occur, affecting network performance. For further information, refer to “Duplex Mode” on page 27.

Each twisted pair port has a maximum operating distance of 100 m (328 feet).

For 10 Mbps operation, Category 3 or better 100 ohm shielded or unshielded twisted pair cabling is required. For 100 or 1000 Mbps operation, Category 5 and Enhanced Category 5 (5E) 100 ohm shielded or unshielded twisted pair cabling is required.

The twisted pair ports are auto-MDI. They automatically configure themselves as either MDI or MDI-X. This feature allows you to use either straight-through or crossover twisted pair cables to connect devices to the ports.

Because all other twisted pair ports on the AT-FS750/24POE Fast Ethernet Smart switch are operating at 10 Mbps and 100 Mbps speeds, the uplink combo ports (ports 25 and 26) provide fiber optic connectivity for the 1000 Mbps speed. Each uplink combo port consists of one 10/100/ 1000Base-T twisted pair port and one SFP port. If both uplink ports are

AT-FS750/24POE specifications

Allied Telesis is renowned for its high-quality networking solutions, and the AT-FS750 series exemplifies this commitment with its robust functionality and advanced features. The AT-FS750/24POE and AT-FS750/48 are two powerful models designed to meet the diverse needs of modern networks, providing reliable connectivity and efficient power management.

The AT-FS750/24POE model is particularly notable for its Power over Ethernet (PoE) capabilities, allowing it to deliver power and data over the same Ethernet cable. This is especially beneficial for deploying devices like IP phones, security cameras, and wireless access points in locations where power sources may be limited. With 24 PoE-enabled ports, the switch can efficiently power multiple devices simultaneously, streamlining installations and reducing clutter.

Conversely, the AT-FS750/48 offers a more extensive configuration with 48 standard Ethernet ports. This model is ideal for larger networks that require seamless connectivity for a higher number of devices. Its robust architecture ensures optimal performance and reliability in demanding environments, making it a preferred choice for enterprises looking to enhance their infrastructure.

A key feature of both models is the Layer 2 switching technology, which ensures high-speed data forwarding and efficient traffic management within the local area network (LAN). This technology supports essential protocols such as VLAN (Virtual Local Area Network) tagging, enabling network segmentation and better security. The switches also boast a high switching capacity, ensuring minimal latency and maximizing throughput for connected devices.

Both AT-FS750 switches are designed with user-friendly management options. They support a web-based interface, simplifying configuration and monitoring tasks for IT staff. Additionally, the switches incorporate SNMP (Simple Network Management Protocol) for streamlined network management, allowing administrators to oversee network performance and troubleshoot issues effectively.

Another notable characteristic is their compact, fanless design, which not only reduces noise but also extends the lifespan of the equipment due to minimized thermal stress. The rugged casing ensures durability, making them suitable for various environments, from small offices to large enterprise networks.

In summary, the Allied Telesis AT-FS750/24POE and AT-FS750/48 switches provide a versatile solution for organizations seeking reliable and efficient networking capabilities. With PoE support, comprehensive management features, and robust performance, these switches are well-suited to meet the evolving demands of today's networking landscape.
