A component level teardown and overview of a Cisco 3750G-24TS-S gigabit Layer 3 switch.
In the first portion of the video we go over the Phihong and Liteon (PA-1201-1) PSU for the 3750G, and in the second portion we concentrate on the motherboard.

This is Part 2 of a video series, mainly catering for repair technicians, but also people into the CCNA certification track might find it interesting as well. Though, for CCNAs Part 1 of the video is more interesting, because here we go into deep details on the hardware. If you are interested in Cisco Stackwise, then Part 1 is definitely an interesting material.
