Chapter 1: Overview

Ports

Twisted Pair Ports

The AT-GS950/48 Gigabit Ethernet Smart switch features 48 twisted pair ports and four SFP ports. See the following sections for more information:

“Twisted Pair Ports”

“Uplink Combo Ports”

The ports on the AT-GS950/48 Gigabit Ethernet Smart switch are capable of 10 megabits per second (Mbps), 100 Mbps, and 1000 Mbps speeds and are 10Base-T, 100Base-TX, and 1000Base-T compliant. In addition, twisted pair ports feature 8-pin RJ-45 connectors.

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 switches 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

For the switch to set the duplex mode for each port correctly, the end nodes that you connect to the switch ports must be configured for Auto-Negotiation. Otherwise, a duplex mode mismatch can occur, affecting network performance. For further information, refer to “Duplex Mode”.

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, which allows you to use either straight through or crossover twisted pair cables to connect devices to the ports.

The four uplink combo ports (ports 45 through 48) consist of an SFP port and a redundant twisted-pair port. The SFP ports support fiber optic connectivity at 100FX and 1000 SX/LX, while the twisted pair ports support 10/100/1000Base-T. If both ports of a combo pair are connected to the network, traffic is switched through the SFP port and the corresponding twisted pair port acts a redundant port in case of failure.

AT-GS950/48 specifications

The Allied Telesis AT-GS950/48 is a robust and high-performance managed Gigabit Ethernet switch designed to meet the demands of modern networks. Ideal for small to medium-sized businesses and enterprise environments, this switch delivers flexible, reliable, and high-speed connectivity while ensuring ease of management.

One of the standout features of the AT-GS950/48 is its offering of 48 Gigabit Ethernet ports, allowing for extensive connectivity options. These ports support auto-negotiation and can automatically detect the highest speed supported by connected devices, ensuring optimal performance. The inclusion of 4 additional SFP (Small Form-factor Pluggable) ports enhances the flexibility of the network design. These SFP ports enable fiber connections, making it easy to extend the network over longer distances or connect to different types of media.

The switch supports advanced Layer 2 features, including VLAN (Virtual Local Area Network) support, which allows network administrators to segment network traffic for enhanced security and performance. The AT-GS950/48 also incorporates features such as Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP) that prevent loops in the network and promote redundancy, ensuring uninterrupted service even in complex networking environments.

Additionally, the AT-GS950/48 supports Power over Ethernet (PoE), which enables the switch to deliver power to connected devices such as IP cameras, VoIP phones, and wireless access points through the Ethernet cable, reducing the need for additional power sources. This PoE capability allows for easier installation and flexibility in deploying network devices.

Allied Telesis places a strong emphasis on security, and the AT-GS950/48 reflects this commitment with features like IEEE 802.1X authentication, which secures network access by allowing only authorized users to connect. The switch also provides access control lists (ACLs) to enhance security by filtering traffic based on various criteria.

With built-in web-based management, the AT-GS950/48 enables administrators to easily configure, manage, and monitor the switch through an intuitive interface. It also supports SNMP (Simple Network Management Protocol) for integration into existing network management systems.

In summary, the Allied Telesis AT-GS950/48 combines high port density, advanced networking features, power delivery capabilities, and robust security measures, making it an excellent choice for organizations looking to build a resilient and efficient network infrastructure.
