Cisco Confidential 17 Chapter 11: Classroom Management  Have the students research a replacement power supply of equal wattage and with the appropriate power connectors.  Provide copies of motherboard documentation to the students. Have the students research the type of memory and the maximum amount of memory that can be supported by that motherboard.  Most of the time spent on memory upgrade is in the planning, selection, and purchasing of memory. Have the students determine what to purchase if a computer with 256K of memory needs to be upgraded to 2GB.  Provide extra hard drives to the students. Have the students install a second hard drive and then partition both drives with different sizes and types of partitions.  Demonstrate flashing the BIOS of lab computers, even if the BIOS is up to date, so the students see the process.  Use an older motherboard to demonstrate the removal and installation of a CPU. Presentation_ID © 2008 Cisco Systems, Inc. All rights reserved. Cisco Confidential 18 Chapter 11: Teaching Analogies  Upgrading a computer is like replacing a part on your car. You must obtain a part that is compatible with your system. Compatibility is very important for the memory, CPU, and power supply of a computer. Presentation_ID © 2008 Cisco Systems, Inc. All rights reserved. Cisco Confidential 19 Chapter 11: Suggested Class Discussions Presentation_ID  What are the different types of certification?  How do you prepare and register for a certification exam?  How can you determine if a processor is compatible with a motherboard?  How can you determine if a particular type and amount of memory is compatible with a motherboard?  What are some reasons to implement different levels of RAID? © 2008 Cisco Systems, Inc. All rights reserved. Cisco Confidential 20 Chapter 11: Best Practices  Obtain old hard drives from technicians or computer stores. Even if they are low capacity, they can be used to demonstrate the concepts of partitioning and formatting.  Install two video adapters and configure dual monitors. This is a common implementation in many work environments. Presentation_ID © 2008 Cisco Systems, Inc. All rights reserved.
