Resistance is futile: Some Cisco security appliances are ticking time bombs of fail thanks to faulty resistors Resistors, which cost a few cents apiece, are bricking pricey Cisco Adaptive Security Appliances (ASAs). A Cisco field notice reveals that models ASA5508 and ASA5516 “might fail in operation, after 18 months or longer, due to a damaged component.” “Due to a manufacturing process issue, some ASA5508 and ASA5516 security …
The only thing I can think of that would result in a particular resistor being prone to failure is if the resistor is dissipating power close to or above its rated wattage. But the only resistors in a digital circuit that dissipate more than a few mW are likely to be in the power supply circuitry. If a PSU goes faulty it would usually result in a total failure of the CPU to run its program, making the device appear completely dead rather than going into blinking-light mode.
So I'd be interested in more detail of what role the failing part plays. I suppose that it could play a role in a power supply that powers a peripheral part rather than the CPU side.
Meh more like planned Obsolescence than a faulty product, working as intended I bet. Bit like the Ipod batteries. We really need a better way to work our businesses, we should be making the best, and making it to last. No designing things to fail or crippling hardware so companies can sell a range... https://www.youtube.com/watch?v=zdh7_PA8GZU
