19" inch wall mounted electrical telecommunication subrack
The width of outside fixing lugs (including the fixing holder) is 482.6mm (19 “).
Width:
The maximum whole width of outside fixing lugs is 449mm. The width of subrack is HP as unit. 1HP equals to 5.08mm (The dimension in the table of standard case only for reference, could be little discrepancy).
Height :
The height unit of case is U, 1U equals to 44.45mm (13/4”)
Depth:
The total depth isn’t stipulated definitely in standard, the concrete size depends on the depth of circuit board, the dimension of rear connector or input&output plug-in unit.
A board plug-in unit is composed of a circuit board with front board and connection unit.
The dimension of the inner front subrack and the behind connection unit are image symmetrical.
One slot comprises several horizontal HP units, or defined in concrete applications.
