Complete tear-down and overview of a Cisco 1941 ISR G2 series router, which are real good devices for small businesses and for being used at a branch office site.
In the video I try to answer the question whether this is a good router for CCNA candidates and small businesses.
In the first portion of the video the hardware and the motherboard is being analyzed in detail from the point of view of a CCNA certification.
In the second portion I make a 10X magnification of the components, and explain their functionality for component-level repair technicians.
Sorry for the dark video, but in spite of 6000 Lumen of light my
Canon Rebel T3i DSLR makes worse movies than a potato.
