Jim makes an important point about the lack of interchangeability between commercial routers and switches and industrial ones. The same thing goes for PCs--perhaps even more so. This article talks about hardening mainly in terms of physical hardening -- resistance to temperature extremes and use of conformal coating as protection. The other aspect is that commerical PCs and network gear have subtle differences from model to model, or even in the same generation. This makes the kind of swapping out that's done in the commercial world much more difficult to get away with in industrial settings, where the gear has to work and be up 100%, without having to constantly send in an IT person to tweak settings and diagnose problems.
The switch may be industrial, but as I commented in the Ethernet in the car article, the connectors are NOT. RJ45 does not belong in industrial settings; it's time for a new robust connector. M12 Code D might be it. Maybe M8 for higher connector densities?
There are a number of vendors out there that make what they might call industrial strength Ethernet devices. There is still room for improvement beyond simple temperature and vibration specs. I would like to see something with an IP-67 rating, for instance, so you don't need to enclose everything.
(TJ, I just added a comment to the auto article as well adressing the plastic tab connector concern).
Researchers at the University of Maryland have achieved a first in lithium-ion battery science: the development of a successful lithium-based battery using one material for all three core components of a battery -- anode, cathode, and electrolyte.
The online Bar Steel Fatigue Database for automotive design engineers has been updated for the fifth time and now contains 134 iterations, or grade/process combinations. It provides better predictability for designing parts with long-term reliability and durability.
FPGAs use programmable fabric to create custom logic, but this flexibility comes at a cost -- usually around 10 times more silicon real estate and 10 times the power dissipation. Can we really claim any FPGA is low power?
