Green Ethernet

The switch provides a Green Ethernet power saving feature on gigabit Ethernet copper ports called Energy Detect Mode. This feature helps reduce chip power by forcing a port PHY into a low-power mode when the signal from a copper link partner is not present. (PHY is an abbreviation for the physical layer of the OSI model.)

When the Energy Detect is enabled, the switch automatically enters the low- power mode when energy on the line is lost, and it resumes normal operation when energy is detected. When the port PHY is in low-power mode, the PHY wakes up after a certain period of time, and sends link pulses to monitor for energy from the link partner. If energy is detected while the port is in wake-up mode, the switch returns the port to normal operation. When the wake-up period expires, the port returns to low-power mode.

Energy Detect works whether the port has autonegotiation enabled or disabled, and can be enabled or disabled by the administrator. The Energy Detect Mode properties are configurable per-port.

See the following topics for more information on the configuration pages available in the Port Management > Green Ethernet menu:

•Configuring Green Ethernet Properties

•Configuring Green Ethernet Port Settings

Configuring Green Ethernet Properties

You can use the Green Ethernet Properties page to enable Green Ethernet functionality globally. The global settings are applied to all ports.

NOTE You can override the global settings by configuring these features on individual ports (see Configuring Green Ethernet Port Settings); however, changes you subsequently make to the global settings override any custom port configuration.

SLM2008PTNA specifications

Cisco Systems SLM2008PTNA is a robust network switch designed specifically for small to medium-sized businesses. It operates with 8 Fast Ethernet ports, providing advanced features and best-in-class performance to enhance your network infrastructure. This model ensures seamless connectivity for multiple devices, making it an ideal choice for environments requiring reliable network communication.

One of the standout features of the SLM2008PTNA is its Layer 2 switching capabilities. This switch supports auto-negotiation, which allows each port to automatically detect the speed of the connected device and adjust accordingly. This ensures optimal performance and smooth operation across various connected devices. Additionally, the switch supports a non-blocking architecture, ensuring that bandwidth is not shared, which significantly enhances data transmission speed.

Power over Ethernet (PoE) is another key technology incorporated into the Cisco SLM2008PTNA. It simplifies the installation of network devices such as VoIP phones, security cameras, and wireless access points by supplying power through the Ethernet cable. This eliminates the need for separate power sources, reducing installation costs and increasing flexibility in device placement.

Moreover, the SLM2008PTNA comes equipped with advanced security features, such as port security and VLAN support. Port security allows network administrators to restrict access to the network based on MAC addresses, preventing unauthorized access and enhancing network security. The support for Virtual Local Area Networks (VLANs) enables the segmentation of the network into different logical networks, improving traffic management and security within each segment.

The switch is designed for easy management and monitoring, featuring a user-friendly web interface that simplifies configuration. This allows network administrators to quickly set up and manage the device without requiring extensive technical knowledge. Additionally, its compact design makes it suitable for desktop or rack-mount installation, maximizing space efficiency in network environments.

In conclusion, the Cisco Systems SLM2008PTNA is an essential component for small to medium-sized businesses looking to enhance their network performance. With its Layer 2 switching capabilities, Power over Ethernet support, advanced security features, and ease of management, this switch provides a well-rounded solution for modern networking needs, delivering reliable performance and scalability for growth.
