Spacing of Mounting Holes

Table 14 specifies the spacing between mounting holes in the chassis’s front support posts and center-mounting brackets. The mounting holes in a front-mount rack’s rails must align with the holes in the front support posts, and the mounting holes in a center-mount rack’s rails must align with the holes in the center-mounting brackets.

Table 14: Spacing of Holes on Front Support Post and Center-Mounting Bracket

Router Mounting Rail	Hole Spacing

Front support post	4 U (7 in. or 17.78 cm)

Center-mounting bracket	3 U (5.25 in. or 13.33 cm)
