Typically, a lab power supply can only operate within a single quadrant. Take a positive voltage power supply for example, it can only output or source current. If any attempt is made trying to sink current into the power supply by connecting a voltage source with a higher voltage than the output voltage of the power supply, the power supply would lose regulation since it cannot sink any current and thus is unable to bring down and regulate the voltage at its output terminals.

My workplace was throwing away an old SMART UF-55 DLP projector. The projector had many stuck mirrors and the lamp had already surpassed the rated useful life span. I had always wanted to take a look at a DMD chip so I decided to take it home and do a detailed teardown. You can find my video of this teardown towards the end of the post.

This old Cisco switch was on its way to the dumpster at my work place, so I thought I would rescue it. After all, while there are plenty of teardowns of consumer grade networking gear on the internet, teardowns of enterprise level network equipment have been hard to come by. So at the very least it would be a good opportunity to take a good peek inside. Continue reading ‘Teardown of a Cisco CSS 11503 Content Services Switch’ »
