System holes

In order to adapt the front panel for direct use in well-known manufacturers' enclosure systems, object ensembles for the mounting of the front panel on the enclosure as well as for the assembly of handles and PCB holders can be inserted.

19" partial front panels only use a number of the 84 horizontal pitch units (HP) available on a 19 "rack .

Their width is equivalent to a corresponding number of HP < 84 (5.08 mm) minus a certain amount (0.34 mm). The height of the 19" partial front panel is a multiple of the rack unit U (44.45 mm) minus a certain amount (4.95 mm).

The system holes for partial front panels in "Front Panel Designer" take into consideration

•	the mounting options on the enclosure

•	the options for assembling handles and PCB holders

The system-specific dimensions of the manufacturers Schroff and Fischer are used as a basis.

With a width of 95 HP, 19" front panels form the front of 19" racks and are mounted using the side mounting holes to the 19" rack systems . The system holes for partial front panels in "Front Panel Designer" take into consideration

•	the mounting options on the enclosure

•	the options for assembling handles

The system-specific dimensions of the manufacturers Schroff and Fischer are used as a basis.

You can determine how to deal with previously inserted system holes:

•	Delete all of the previously inserted system holes (default "delete system holes").

•	Keep those previously inserted system holes, whose properties have been edited in any way ("delete unmodified system holes").

•	Keep all of the previously inserted system holes ("keep system holes")
