• After upgrading the IOS on a device, it is necessary to observe the boot up process to ensure that software is loaded correctly and functioning properly.
• There are three stages to the device boot up process:
• 1.the POST testing and the initial bootstrap software load,
• 2. locating and loading the Cisco IOS software, and
• 3. locating and loading the configuration file.
•
• When incorporating existing equipment into a new network design, the designer needs to be aware of the hardware options and upgrades that are available. Cisco.com is a good resource to find this information.
•
• Before producing a wireless network design, it is usually necessary to do a wireless site survey.
•
• Wireless site surveys identify the coverage areas and any sources of interference that affect the wireless signal.

3. Characterizing Existing Network
3.1 Documenting the existing network
3.1.1 Creating a network diagram
Typically, the first step in installing a new network is to take a detailed look at the existing network. The Networking Company designer examines the existing network to:
• Determine if the design goals are realistic and feasible
• Determine if the existing network meets the expectations for scalability, availability, security, and manageability
• Identify where new equipment, infrastructure upgrades, and new services can be integrated
• Ensure that old and new network devices, media, and functions can work together
