[dsg-svt] Location of SVT sensitive components on the service cart

[Brian Eng]

Hall B will need to buy/provide the network cable and connectors to run 16 cables instead of the 2 that were already run if the switches need to be moved off the cart.

There would also need to be some coordination with fast electronics for the UPSes to be moved since none of the AC power cables would reach.

Personally I'd prefer to move (radially away from the beam) the equipment and/or shield it before moving it off the cart.

Moving the network switches would be desirable. Maybe the UPS too. Lowering the accumulated dose would increase reliability of the component and reduce the probability of the detector down time.
