Firmware Recovery Over HTTP

The switch has a firmware recovery feature that enables the restoration of a valid image on the switch after a failed download. If the power goes down during an image download, the switch might not be able to boot. In this event, although the image is not usable, the boot loader file that loads the firmware image from Flash memory to RAM should continue to be functional. An HTTP server is embedded in the boot loader file, enabling the administrator to connect to the switch over a switch port and use a web browser to download and install a new firmware image.

The switch enters the HTTP firmware recovery mode when the switch is booted and the boot loader cannot find a valid image in flash memory. In this mode, the boot loader sets the switch internal network port to the following static IP address:

IP Address: 192.168.1.254

Network Mask: 255.255.255.0

Default Gateway: 192.168.1.1

An HTTP server starts and listens for client connections on port 80.

NOTE Firmware recovery can also be performed using the command line interface. Refer to the Cisco Small Business SF200E Command Line Reference.

To use this feature to download a new firmware image:

STEP 1 Directly connect a management PC to any switch port.

STEP 2 Configure the IP address and mask on the management PC to be in the same subnet as the switch.

NOTE: You can access the system across a network if the default gateway IP address is 192.168.1.1.

STEP 3 Open a web browser and enter the IP address of the switch in the address bar (192.168.1.254).

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.
