x610 Series Layer 3 Gigabit Ethernet Switches Installation Guide

Twisted Pair Port Link LED is Off

When a twisted pair port on the switch is connected to a properly operating end node, the Link LED for the port should be on. If a Link LED is off, do the following:

Note

A 1000Base-T connection can take from five to ten seconds to establish a link.

Verify that the end node connected to the port is powered ON and is operating properly.

Check that the twisted pair cable is securely connected to the port on the switch and to the port on the end node.

Make sure that the twisted pair cable does not exceed 100m (328 ft).

Verify that you are using the appropriate category of twisted pair cable. For information, refer to Table 17 on page 98.

Determine if a crossover cable is required. Since the twisted pair ports feature auto MDI/MDI-X, you should be able to use a straight-through cable regardless of the type of device you connect to a port. However, if you disable Auto-Negotiation on a port and set a port’s speed and duplex mode manually, the port defaults to MDI-X. Disabling Auto- Negotiation may require manually configuring a port’s MDI/MDI-X setting or using a crossover cable.

Make sure that the operating parameters of a port on the switch are compatible with the end node to which the port is connected. This may require using the switch’s operating system software.

For a switch port to successfully Auto-Negotiate its duplex mode with an end node, the end node should also be using Auto-Negotiation. Otherwise, a duplex mode mismatch can occur. A switch port using Auto-Negotiation defaults to half-duplex if it detects that the end node is not using Auto-Negotiation. This can result in a mismatch if the end node is operating at a fixed duplex mode of full-duplex.

To avoid this problem, disable Auto-Negotiation on a switch port and set the port’s speed and duplex mode manually if the end node has a fixed duplex mode of full-duplex.

The switch has a bad cable detection feature that enables it to determine if a twisted pair cable has a electrical short that might cause a network loop. If the switch detects a bad cable on a port, it does not establish a link on that port. In this situation, replace the 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.
