Allied Telesis Switch Manual: AT-FS750/24 & AT-FS750/16 Overview

Chapter 1: Overview

Ports

Twisted Pair Ports

Uplink Combo Ports

RS-232 Console Port

The AT-FS750/16 and AT-FS750/24 Fast Ethernet Smart Switches feature 16 or 24 twisted pair ports and two pairs of uplink combo ports.

The twisted pair ports are 10Base-T and 100Base-TX compliant. They automatically set their speed and duplex mode with IEEE 802.3u Auto- Negotiation. If desired, you can disable Auto-Negotiation on a port and manually set the speed and duplex mode.

Note

If a switch port is connected to an end node that is not using Auto- Negotiation, you should disable Auto-Negotiation on the port and set its speed and duplex mode manually. Otherwise, a duplex mode mismatch can occur.

The ports have 8-pin RJ-45 connectors. For the port pinouts, refer to “Connectors and Port Pinouts” on page 42.

The ports have a maximum operating distance of 100 m

(328 feet). For 10 Mbps operation, the ports require Category 3 or better 100 ohm shielded or unshielded twisted pair cabling. For 100 Mbps operation, the ports require Category 5 or Enhanced Category 5 (5E) 100 ohm shielded or unshielded twisted pair cabling.

Also featured on the ports is auto-MDI, which automatically configures the ports as MDI or MDI-X. This allows you to use straight-through twisted pair cable regardless of the configuration of the ports on the end nodes.

The switch has two pairs of uplink ports, each consisting of one 10/100/ 1000Base-T twisted pair port and one slot for an optional SFP transceiver. The ports are numbered 17 and 18 on the AT-FS750/16 Switch and 25 and 26 on the AT-FS750/24 Switch. These combo ports can be used to connect high speed devices to your network or to connect devices over large distances.

You can use one port in a combo pair at a time. A link on an SFP transceiver always takes precedence over a link on a 10/100/1000Base-T twisted pair port in the same combo pair. If the SFP slot is empty or if it has an SFP module but the module does not have a link to an end node, the 10/100/1000Base-T twisted pair port of the pair is active. If an SFP transceiver is installed and has a link to an end node, the twisted pair port in the pair is inactive.

The RS-232 console port is for local management of the switch with the AT-S80 Management Software. Local management uses the management cable supplied with the switch.

AT-FS750/24, AT-FS750/16, FS750/24, FS750/16 specifications

The Allied Telesis AT-FS750 series is a robust line of Fast Ethernet switches designed for efficient networking in both small and medium-sized business environments. This series includes models such as the AT-FS750/24 and AT-FS750/16, as well as the FS750/16 and FS750/24, each offering unique features tailored to specific network requirements.

One of the main features of the AT-FS750 series is its high port density, with models like the FS750/24 providing 24 Fast Ethernet ports and models like the FS750/16 offering 16 ports. This extensive port availability allows organizations to expand their networks seamlessly, accommodating various devices from computers to printers without the need for additional switches.

The switches support a range of Ethernet technologies, including auto-negotiation, which automatically adjusts the speed and duplex settings efficiently, ensuring optimal performance. This feature is particularly beneficial in dynamic network environments where devices of varying speeds may be connected.

Reliability is a hallmark of the AT-FS750 series, as these switches are designed with enhanced power supply features that allow for redundancy and minimize downtime. The devices also come equipped with advanced network management features, enabling administrators to efficiently monitor and control network traffic. All models in the AT-FS750 series support VLAN (Virtual Local Area Network) configuration, allowing for network segmentation and improved security.

Moreover, the AT-FS750 series switches implement Quality of Service (QoS) mechanisms that prioritize critical network traffic, ensuring that key applications, such as voice over IP and video conferencing, receive the bandwidth they need for uninterrupted service. This capability is crucial for businesses that rely on consistent communication channels.

Additionally, the switches offer a compact form factor, making them suitable for installation in a variety of environments, including smaller server rooms and office spaces. Their fanless design contributes to quiet operation, ideal for workspaces that require a noise-free atmosphere.

In summary, the Allied Telesis AT-FS750/24, AT-FS750/16, FS750/16, and FS750/24 switches are designed with reliability and efficiency in mind. With advanced Ethernet technologies, extensive management features, and a focus on security and performance, these switches cater to businesses looking for scalable networking solutions that grow with their evolving needs.
