Clear answers to common questions about PCB repair, diagnostics, failure analysis, and refurbishment.

Network switches run continuously for years, and when one finally fails, the cause is usually one of a handful of well-understood patterns rather than a mystery.
A switch that has stopped working can be failing for power reasons, port reasons or software reasons. A few safe, non-invasive checks narrow it down before anyone considers replacing it.
An ISP's equipment budget is driven by the volume of failures. Understanding why equipment fails, and having a repair route for the rest, brings that cost down.
Often, yes. Whether it is worth doing depends on what failed, whether the unit is indoors or outdoors and how much a replacement would cost.
Switches, routers and access points are often retired while they still have useful life. Refurbishment tests them, repairs what is wrong and returns them as spares or for lower-priority sites.
