Configuring PoE Port Settings

You can use the Port Settings page to view and configure settings for ports acting as PSEs.

To configure PoE settings for a port:

STEP 1 Click Port Management > PoE > Port Settings in the navigation window.

The PoE Setting Table displays which ports are enabled for PoE operation, their priority, power allocation in milliwatts, and other settings for each port.

STEP 2 Select the port to configure and click Edit.

STEP 3 Configure the following settings:

PoE—Check the Enable box to configure the port as a PSE.

Power Priority Level—Select Critical, High, or Low to configure the port priority level, for the delivery of power to an attached device.

The switch might not be able to supply power to all connected devices that request it. The port priority determines which ports supply power when adequate power capacity is not available for all enabled ports. For ports that have the same priority level, the lower-numbered port has higher priority. For a system delivering peak power to a certain number of devices, if a new device is attached on a high-priority port, power is shut down to a device on a low-priority port, and the new device is powered up.

Power Limit Type— Select one of the following methods to limit the power that the switch provides to a connected device.

-Dot3AF—The maximum power that can be delivered by the port is limited by the detected IEEE 802.3af class.

-User-defined—The maximum power that can be delivered by the port is specified by the user. If you select this option, specify a value in the Power Allocation field.

-LLDP-MED—The maximum power that can be delivered by the port is limited by the value in LLDP-MED TLVs received from a port device. The value specified by the device should be in the range of 3-16.2 watts. If it is not in this range, then the default value of 16.2 watts is used.

Note: If the selected Power Limit Type is LLDP-MED, then the priority setting from the remote device is not honored; instead the switch uses the Power Priority Level setting configured for the port.

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.
