This chapter contains information on how to troubleshoot the switch if a problem occurs.

Note

For further assistance, please contact Allied Telesis Technical

Support. Refer to “Contacting Allied Telesis” on page 14.

Check the POWER LED on the front of the switch. If the LED is off, indicating that the unit is not receiving power, do the following:

ˆVerify that the power cord is securely connected to the power source and to the AC connector on the back panel of the switch.

ˆVerify that the power outlet has power by connecting another device to it.

ˆTry connecting the unit to another power source.

ˆTry using a different power cord.

ˆVerify that the voltage from the power source is within the required levels for your region.

Verify that the LINK/ACT LED for each port is ON. If a LINK/ACT LED is

OFF, do the following:

ˆVerify that the end node connected to the port is powered on and is operating properly.

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

ˆVerify that the twisted pair cable does not exceed 100 meters (328 feet).

ˆVerify that you are using the appropriate category of twisted pair cable: Category 3 or better for 10 Mbps operation and Category 5 and Category 5E for 100 and 1000 Mbps operation.

Note

A 1000Base connection may require five to ten seconds to establish a link.

AT-GS950/16-10, AT-GS950/16 specifications

The Allied Telesis AT-GS950/16 and AT-GS950/16-10 are powerful, high-performance Gigabit Ethernet switches designed to meet the demands of today's networks. Known for their reliability and advanced feature set, these switches are ideal for small to medium-sized businesses that require robust networking capabilities.

One of the standout features of both models is their 16 Gigabit Ethernet ports. This configuration allows for a high bandwidth capacity, making it perfect for handling multiple devices and applications simultaneously. The AT-GS950/16 ensures that your network can support a large number of users without experiencing latency issues. The AT-GS950/16-10 variant specifically offers ten additional management features, enhancing control over network operations.

Both models utilize Layer 2 switching technology, providing efficient data transfer between devices within the network. They support advanced switching technologies, such as VLAN (Virtual Local Area Network) capabilities, which enable network segmentation for improved performance and security. This allows IT administrators to group devices into logical networks, reducing broadcast traffic and making it easier to manage network resources.

In terms of security, the AT-GS950 series includes features such as port security and MAC address filtering to prevent unauthorized access to the network. These features enhance overall security and help protect sensitive data from potential breaches.

The AT-GS950/16 and AT-GS950/16-10 switches also support Quality of Service (QoS) protocols, ensuring that time-sensitive traffic such as VoIP and video streaming receive priority in the network. This is crucial for maintaining high-quality service and user experience in environments where performance is key.

Additionally, both switches are designed with energy efficiency in mind, supporting IEEE 802.3az Energy Efficient Ethernet standards. This not only reduces operational costs but also contributes to a more sustainable network environment.

With a compact form factor, the AT-GS950 series can easily fit into standard network racks or can be deployed on a desktop. Its intuitive web-based graphical user interface (GUI) simplifies setup and management, allowing even non-technical users to configure settings effortlessly.

In summary, the Allied Telesis AT-GS950/16 and AT-GS950/16-10 switches deliver a combination of scalability, security, and efficiency, making them a reliable choice for organizations looking to build or expand their network infrastructure. Their advanced features and performance capabilities ensure they can meet the evolving needs of modern businesses.
