Note

The auto-MDI/MDI-X feature on the 10/100/1000Base-T ports automatically configures the MDI/MDI-X setting when a link is established with an end node. Available when a port is at the default setting of Auto-Negotiation, this feature allows you to use a straight- through twisted pair cable when connecting any type of network device to a port.

Disabling Auto-Negotiation on a port and setting the speed and duplex mode manually also disables the auto-MDI/MDI-X feature. A port where Auto-Negotiation has been disabled defaults to MDI-X. Disabling Auto-Negotiation may require manually configuring a port’s MDI/MDI-X setting or using a crossover cable.

Allied Telesis has made a significant mark in the networking hardware industry with its impressive lineup of switching solutions. Among these, the X610 series stands out, offering a range of models including the X610-48TS, X610-24TS/X-POE+, X610-24TS/X, X610-48TS-POE+, and X610-24TS-POE+. These switches are designed for robust performance, scalability, and energy efficiency, catering to the needs of businesses and organizations of various sizes.

The X610-48TS model features 48 Gigabit Ethernet ports, providing high-density connectivity options that are essential for modern network architectures. Complementing this, the X610-24TS models, which come with 24 ports, are ideal for smaller deployments while still delivering significant capacity and performance. The X610-24TS/X-POE+ variant enhances this capability further by incorporating Power over Ethernet, enabling the switch to deliver both data and power over the same cable. This feature simplifies installations of IP-based devices such as cameras, phones, and wireless access points.

All models in the X610 series support advanced Layer 2 and Layer 3 features, enabling efficient network management and control. With support for VLANs, Spanning Tree Protocol, and link aggregation, these switches facilitate better traffic management and redundancy, crucial for maintaining high availability in enterprise environments. Additionally, the ability to implement Quality of Service (QoS) ensures that critical applications receive the bandwidth necessary for optimum performance.

Energy efficiency is a hallmark of Allied Telesis products, and the X610 series is no exception. The switches incorporate technologies like Energy Efficient Ethernet (EEE), which helps reduce power consumption during periods of low network activity, thus lowering operational costs while supporting eco-friendly initiatives.

Security features are also robust, with mechanisms such as access control lists (ACLs), port security, and built-in DHCP snooping ensuring that the network remains secure against unauthorized access and threats. The switches are designed with a user-friendly interface for easy configuration and management, including support for SNMP and a web-based management interface.

In conclusion, Allied Telesis' X610 series, with its various models, offers an impressive blend of performance, scalability, and energy efficiency. These switches are well-suited for a wide variety of applications, making them an ideal choice for organizations looking to upgrade or establish a reliable networking infrastructure. Their advanced features, coupled with a focus on security and management, provide organizations with the tools necessary to handle current and future networking demands.
