Cisco 2960G Switch teardown an detailed overview for CCNA lab and repair -Part2

Complete tear-down and overview of a Cisco 2960G gigabit switch for CCNA candidates and also for IT repair technicians.

At the first half of the video I go over the main components which are the Flash, NVRAM, Route-Processor and ASIC from the perspective of a CCNA. On the CCNA exam you do not need to know such details, but it helps you to be able to visualize the data flow, and to give you a rough idea about the hardware.

In the secon half of the video I go over the mainboard components in deep detail, and explain their functionality within the Switch. This part is going way beyond CCNA, instead it caters for component-level repair technicians.
If you are interested in the disassembly and the PSU, watch Part1 of this video series:

Some portions of ot the video got lost because of the Kdenlive Linux video editor, sorry for the choppy video.
