Resetting to the Default Configuration

Reconfiguration Steps for Boot Block Version 1.01 or Earlier

Follow these steps to reconfigure your access point if the boot block version on your access point is version 1.01 or earlier and the firmware version on your access point is 11.06 or earlier. To find which boot block version is on your access point, follow the steps in the “Determining the Boot-Block Version” section on page 4-5.

Caution Failure to follow these instructions correctly can result in a nonoperational access point that must be returned to the factory. If your access point stops working after you attempt this procedure, contact Cisco TAC for assistance.

Step 1 Use a straight-through cable with 9-pin male to 9-pin female connectors to connect the COM 1 or COM 2 port on your computer to the RS-232 port on the access point.

Step 2 Open a terminal-emulation program on your computer.

Note These instructions describe HyperTeminal; other programs are similar.

Step 3 In the Connection Description window, enter a name and select an icon for the connection and click OK.

Step 4 In the Connect To window, select the port to which the cable is connected and click OK.

Step 5 In the Port Settings window, make the following settings: 9600 baud, 8 data bits, No parity, 1 stop bit, and Xon/Xoff flow control.

Step 6 Click OK and press Enter three times.

Step 7 When the Summary Status screen appears, reboot the access point by unplugging the power connector and then plugging it back in, or by pressing Ctrl-X.

Step 8 When the message “Type <esc> within 5 seconds for menu” appears, press Esc.

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

Caution Perform the next six steps carefully to avoid accidentally 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 installation key file 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 called AP Installation Key.

Step 11 If the list of configuration files contains a file called VAR Installation Key, copy that file to DRAM along with the AP Installation Key. Copy the VAR installation key file to DRAM by pressing c to select Copy file, then 1 to select DRAM, then the selection letter for the file called VAR Installation Key.

Caution Make sure you select the Configuration memory bank for formatting in Step 12. If you accidentally format a different memory bank your access point will stop functioning.

Step 12 Reformat the access point’s configuration memory bank by pressing ! to select FORMAT memory bank, then 2 to select Config, then upper-case Y to confirm the FORMAT command.

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.
