PoE Status

 

 

 

 

 

Off

 

PoE mode is not selected. No port has been denied power or is in a fault condition.

 

 

 

Green

 

PoE mode is selected, and the port LEDs show the PoE status.

 

 

Blinking amber

PoE mode is not selected. At least one port was denied power, or at least one port

 

 

has a PoE fault.

 

 

 

 

 

 

 

To select or change a mode, press the Mode button until the desired mode is highlighted. When you change port modes, the meanings of the port LED colors also change.

Meaning

 

 

 

 

 

 

PoE

 

Off

PoE is off. If the powered device is receiving power from an AC

 

 

 

 

power source, the port LED is off even if the powered device is

 

 

 

 

connected to the switch port.

 

 

 

 

 

 

 

 

Green

PoE is on. The port LED is green only when the switch port is

 

 

 

 

providing power.

 

 

 

 

 

 

 

 

Alternating

PoE is denied because providing power to the powered device will

 

 

 

green and

exceed the switch power capacity.

 

 

 

amber

 

 

 

 

 

 

 

 

 

 

 

 

Blinking amber

PoE is off due to a fault.

 

 

 

 

 

 

 

 

 

 

 

 

Caution Noncompliant cabling or powered devices can cause a

 

 

 

 

 

 

 

PoE port fault. Use only standard-compliant cabling to

 

 

 

 

 

 

 

connect Cisco prestandard IP Phones and wireless access

 

 

 

 

 

 

 

points or IEEE 802.3af-compliant devices. You must

 

 

 

 

 

 

 

remove any cable or device that causes a PoE fault.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Amber

PoE for the port is disabled. (PoE is enabled by default.)

Cisco Systems 2960 series switches are a prominent solution in the networking landscape, known for their reliability, scalability, and feature-rich offerings. Ideal for small to medium-sized enterprises, these switches provide a robust foundation for network infrastructure, ensuring optimal performance and connectivity.

One of the standout features of the Cisco 2960 series is its Layer 2 switching capabilities. The switches support multiple VLANs (Virtual Local Area Networks), allowing network administrators to segment traffic efficiently and enhance security protocols. This is crucial in modern networks where managing traffic and isolating sensitive information is a priority.

The Cisco 2960 series also incorporates advanced Quality of Service (QoS) features, enabling the prioritization of critical applications and services. This functionality ensures that time-sensitive data, such as voice and video traffic, maintains a high quality of service even in congested networks. With support for IEEE 802.1p and DSCP marking, administrators can fine-tune their network performance to meet specific organizational needs.

Power over Ethernet (PoE) is another significant characteristic of the Cisco 2960 series. This feature allows switches to deliver electrical power alongside data over Ethernet cables to devices such as IP phones, wireless access points, and surveillance cameras. With PoE, organizations can reduce clutter from power cables and increase deployment flexibility for various devices.

In terms of security, the Cisco 2960 series is equipped with a range of integrated security features. The switch supports port security, 802.1X authentication, and Access Control Lists (ACLs), providing robust defenses against unauthorized access and potential network vulnerabilities. These security measures are essential for protecting sensitive data and ensuring compliance with industry regulations.

Moreover, the Cisco 2960 series offers enhanced network management capabilities with Cisco's Intelligent Network Services. This includes support for Simple Network Management Protocol (SNMP), Cisco Prime, and Embedded Event Manager (EEM), allowing for efficient monitoring, troubleshooting, and policy enforcement across the network.

Additionally, the Cisco 2960 switches provide various models and configurations, catering to different networking needs. Options include models with varying port densities, uplink configurations, and stacking capabilities, making it easy for organizations to choose solutions that align perfectly with their requirements.

In summary, the Cisco 2960 series is a versatile and essential component of modern networking environments. Its advanced features, including Layer 2 support, QoS, PoE, robust security, and diverse management tools, make it an excellent choice for organizations looking to build a strong and secure network infrastructure.
