Unmatched Flexibility

The x900 Layer 3+ switches have high-speed 60Gbps expansion bays which provide a high level of port flexibility and application versatility unmatched by any other 1RU Gigabit Ethernet switch on the market.The expansion modules can be used in a variety of configurations to provide tailored solutions that meet wide-ranging physical networking requirements.

10GbE expansion modules and hot-swappable XFPs provide high-speed, high-capacity fiber uplinks, with the option of either 10Gbps or 20Gbps uplink capacity to the network core. Resiliency can be achieved by using 10GbE modules and MSTP (802.1s) for fast failover on link failure.This is suitable for wiring closet aggregation of gigabit to the desktop links and aggregating gigabit uplinks from other network switches.

Ethernet Protected Switched Rings (EPSR) and 10 GbE modules allow several x900-24X switches to form a protected ring with sub 50ms failover.This feature is perfect for high performance at the core of enterprise or provider access networks.

x900-12x, x900-24x specifications

Allied Telesis has established a strong presence in the networking industry with its innovative range of products, among which the x900-24x and x900-12x series is notable. These switches are designed to meet the demands of modern enterprise networks, providing robust performance, scalability, and advanced features for optimal network management.

The Allied Telesis x900-24x model is a 24-port Gigabit Ethernet switch, while the x900-12x model features 12 ports. Both switches are equipped with a variety of features that enhance their functionality. A significant characteristic of the x900 series is its layer 3 capabilities, which allow for advanced routing functions. This is essential for organizations looking to segment their networks and improve performance through efficient traffic management.

One of the standout features of these switches is their high-speed stacking capability. This allows multiple switches to be connected, effectively functioning as a single logical unit, which simplifies management and increases redundancy. The x900 series supports up to 48 Gbps stacking bandwidth, making it easy for businesses to expand their network without compromising performance.

Security is another priority for Allied Telesis, and the x900 switches come with a range of features, including Access Control Lists (ACLs) and IEEE 802.1X port-based authentication. These features help protect sensitive data and ensure that only authorized users can access the network. Additionally, the inclusion of DHCP snooping and dynamic ARP inspection contributes to enhanced security.

Performance-wise, the x900 series is optimized for handling high traffic loads, thanks to their non-blocking architecture and wire-speed performance. This ensures that data is transmitted quickly and efficiently, reducing latency and improving overall user experience.

The switches also support a variety of management options, including SNMP, Web-based interfaces, and an intuitive Command Line Interface (CLI). This flexibility makes it easier for IT administrators to configure, monitor, and manage the network.

In summary, the Allied Telesis x900-24x and x900-12x switches offer a powerful, reliable, and secure networking solution suitable for modern enterprise environments. Their robust features, such as stacking capability, advanced security options, and high performance, ensure that they can handle the challenges of today’s dynamic and demanding network landscapes. These switches are well-suited for organizations looking to enhance their network infrastructure and maintain optimal performance.
