Network Gear Seismic Tolerances

Look at marine equipment specs.   They define vibration tolerances quite well.   Not my specialty, but I had brief exposure one time.

The cabinets are effectively "floating," well, rolling really, on the data center floor. There are various vendor solutions for this. Of course, the network gear living up close and personal with the servers is along for the ride. That's all fine. I don't think it's a problem for the network gear.

I am trying to find any real information about this, but Google-fu is not producing results for me. I asked some of our vendor sales people, they said they'd get back, but never did. I don't know if shake tolerances is something published for your typical data center and campus network gear.
