|
- CPCI-serial backplane **power bags** touching the rail -> confirmed with Michal that he will move the power bags higher to ensure that with different crate manufactures there wont be a risk
|
|
- **ACTION A5:** **Rails** to confirm they have the ESD protection;
|
|
|
|
|
|
- Checked with Michal that the **font panel** will be a pcb screwed on the metal plate

For power cards rails could be green, as in off-the-shelf crates;

It seems there are only red rails for RTMs, to be confirmed; ideally they should all be grey but the one of the AUX power supply, which should be green

- It is probable to be **compatible with other manufacturers**, but it would be a different analysis for Creotech to check for that; CERN could ask directly ELMA/ATOS for their equivalent BOMs and 3D models

* We need to protect user from being electrocuted by accidentally touching **230V cables going to the front panel**. You will evaluate 2 solutions: 1) enclosing front panel in a "metal box" where 230V cables enter through a hole in the back and other than this, it is covered from all sides; 2) 2 metal plates separating slot 9 and PSU slot from the front panel area.
