Hi Kurt! My apologies; I imagined your situation as being a 19" rack with various units (1U servers, network switches, etc) plugging to one or more PDUs. There are some mechanical tricks you can do to mitigate the long-screw problem, but it sounds like your product is already well past the design

Dear Ken its a 19 inch rack mountable product with a backplane and several submodule plug-in pcb's. It has a metall case for mounting it into a 19 inch rack. >From the protection class point of view its a class I (protection earth) product. Good point regarding assembly failures and wiring failure

Hi Kurt! At the system (end product level); -Do you add a PDU and plug on the manufacturing line and plug all the modules into it? -Do you have small screws, wires, etc which are used to assemble the end product which might fall into the product? -Do you have any opportunity for miswiring/misplugg

Hi all, i am defining the routine tests for a 19 inch Rack System according to IEC 60950-1 and IEC 62368-1. We test routinely the solid insulation of each submodule during production. The final system is variable, so some modules are sometimes in the system or not, depending on the configuration f
