Chapter 4 Troubleshooting

Resetting to the Default Configuration

Step 9 Write down the list of files for future reference.

Caution Perform the next six steps carefully to avoid accidently deleting the installation key files or the firmware files. You must carefully note the file selection letters, because they change during the following steps. If you forget to copy the access point’s installation key file to DRAM in Step 10, or if you do not copy it back to configuration memory in Step 13, your access point will stop functioning.

Step 10 Copy the access point’s AP Installation Key to the access point’s DRAM by pressing c to select Copy file, then 1 to select DRAM, then the selection letter for the file AP Installation Key.

Step 11 If the list of configuration files contains a file called VAR Installation Key, you must copy that file to DRAM along with the AP Installation Key file. If the access point does not have a VAR installation key file, skip to Step 12.

Caution If you forget to copy the access point’s VAR installation key file to DRAM in Step 11, or if you do not copy it back to configuration memory in Step 14, your access point will stop functioning.

Copy the VAR Installation Key to DRAM by pressing c to select Copy file, then 1 to select DRAM, then the selection letter for the file VAR Installation Key.

Step 12 Reformat the access point’s configuration memory bank by pressing Ctrl-Zto reach the reformat menu. When the menu appears, press ! to select FORMAT memory bank, then 2 to select Config, then upper-case Y to confirm the FORMAT command.

Caution Make sure you select the Configuration memory bank for formatting. If you accidentally format a different memory bank your access point will stop functioning.

Step 13 Copy the installation key back to the configuration memory bank by pressing c to select Copy file, then 2 to select Config, then the selection letter for the file AP Installation Key.

Step 14 If you copied a VAR installation key to DRAM in Step 11, copy it back to the configuration memory bank by pressing c to select Copy file, then 2 to select Config, then the selection letter for the file VAR Installation Key. If the access point does not have a VAR installation key file, skip to Step 15.

Step 15 Run the access point firmware by pressing r to select Run, then the selection letter for the firmware file that is displayed. The message “Inflating [firmware file name]” appears while the access point starts the firmware.

Step 16 When the Express Setup screen appears, begin reconfiguring the access point using the terminal emulator or an Internet browser.

Cisco Systems 350, 340 manual Troubleshooting Resetting to the Default Configuration

340, 350 specifications

Cisco Systems has long been a prominent player in the realm of networking and communications technology. Among its comprehensive product lineup, the Cisco 350 and 340 series of switches stand out as reliable solutions for businesses looking to enhance their network performance.

The Cisco 350 series, often referred to for its accessibility and performance, is designed for small to medium-sized enterprises. It offers a versatile set of features that cater to various networking needs. Key characteristics include a range of models supporting 10/100/1000 Mbps Ethernet ports, which allow for high-speed connectivity. The series also supports PoE (Power over Ethernet) capabilities, enabling devices such as IP phones and wireless access points to receive power directly through the network connection. This not only simplifies deployment but also minimizes the need for additional power supplies.

Cisco's Intelligent Prosumer Networking features are incorporated into the 350 series, enabling enhanced security and management capabilities. The switches provide Layer 2 and Layer 3 functionality for routing and switching, allowing users to segment their networks efficiently and reduce broadcast traffic. Additionally, Quality of Service (QoS) features prioritize critical applications, ensuring a smooth user experience without interruptions.

On the other side, the Cisco 340 series builds on similar performance foundations but targets environments requiring even more robust capabilities. It includes advanced features such as StackWise technology, which provides scalability and redundancy. This allows multiple switches to operate as a single unit, improving network resilience and simplifying management.

Both the 350 and 340 series incorporate Cisco's Smart Group technology, facilitating streamlined configuration and easier monitoring of network performance. Furthermore, with Cisco DNA (Digital Network Architecture) capabilities, these switches can support automation and insights through analytics, enabling IT teams to respond rapidly to network demands.

In terms of security, both series are equipped with advanced features that prevent unauthorized access and support secure management protocols. They include features like Access Control Lists (ACLs) and storm control, further protecting network integrity.

Overall, whether you opt for the Cisco 350 or 340 series, you will benefit from a robust set of features designed for modern networking challenges, along with the innovation and reliability that Cisco Systems is known for. These switches provide scalable, efficient, and secure solutions to support business growth and operational efficiency.
