Installing the SRX5800 Services Gateway Mounting Hardware in an Open-Frame Rack

Before installing the services gateway in an open-frame rack, install the large mounting shelf on the rack. The small mounting shelf is not needed.

If you are front-mounting the services gateway, also remove the center-mounting brackets located on each side of the chassis.

Table 1 specifies the holes in which you insert screws to install the mounting hardware in an open-frame rack (an X indicates a mounting hole location). The hole distances are relative to one of the standard “U” divisions on the rack. For reference, the bottom of all mounting shelves is at 0.04 in. (0.02 U) above a “U” division.

Table 1: Open-Frame Rack Mounting Hole Locations

Hole	Distance Above “U” Division		Large Shelf
30	17.26 in. (43.8 cm)	9.86 U	X
27	15.51 in. (39.4 cm)	8.86 U	X
24	13.76 in. (34.9 cm)	7.86 U	X
21	12.01 in. (30.5 cm)	6.86 U	X
18	10.26 in. (26.0 cm)	5.86 U	X
15	8.51 in. (21.6 cm)	4.86 U	X
12	6.76 in. (17.1 cm)	3.86 U	X
9	5.01 in. (12.7 cm)	2.86 U	X
6	3.26 in. (8.3 cm)	1.86 U	X
3	1.51 in. (3.8 cm)	0.86 U	X
2	0.88 in. (2.2 cm)	0.50 U	X
1	0.25 in. (0.6 cm)	0.14 U

To install the large mounting shelf (see Figure 1):

On the rear of each rack rail, partially insert a mounting screw into the highest hole specified in Table 1 for the large shelf.
Install the large shelf on the rack. Hang the shelf over the mounting screws using the keyhole slots located near the top of the large shelf flanges.
Partially insert screws into the open holes in the ears of the large shelf.
Tighten all the screws completely.
