Installing Cage Nuts, If Needed
Insert cage nuts, if needed, into the holes listed in Table 1 and Table 2 (an X indicates a mounting hole location). The hole distances are relative to the standard U division on the rack that is aligned with the bottom of the mounting shelf and rear support bracket.
To install cage nuts in a four-post rack:
- On the rear rack rails, insert cage nuts in the holes specified for the rear support bracket. Install the cage nuts in the rear of the rear rail (see Table 1).
- On the front rack rails, insert cage nuts in the holes specified for the four-post mounting shelf. Install the cage nuts in the front of the front rail. (see Table 1)
- On the front rack rails, insert cage nuts in the holes specified for mounting the chassis. Install the cage nuts in the front of the front rail. (see Table 2)

Installing the Four-Post Mounting Shelf and Rear Support Bracket
To install the four-post mounting shelf and rear support bracket (see Figure 1):
- On the rear of each rear rack rail, partially insert a mounting screw into the lowest hole specified in Table 1.
- Install the rear support bracket on the rear of the rear rack rails. Rest the bottom slot of the rear support bracket on a mounting screw. The rear support bracket extends toward the center of the rack.
- Partially insert screws into the open holes in the rear support bracket.
- Tighten all the screws completely.
- On the front of each front rack rail, partially insert a mounting screw into the lowest hole specified in Table 1.
- Install the four-post rack mounting shelf on the front rack rails. Rest the bottom slot of the front flange on a mounting screw. Rest the back of the four-post rack mounting shelf on top of the rear support bracket.
- Tighten all the screws completely.
- Fasten the four-post mounting shelf to the rear
support bracket by partially inserting the screws provided in the
accessory kit into the open holes on top of the four-post mounting
shelf.
Note: Several holes are provided on top of the shelf. Two holes on each side of the shelf will align with the holes in the rear support bracket.
- Tighten all the screws completely.

Removing the Center-Mounting Brackets
The center-mounting brackets are not used for a four-post rack, and must be removed from the chassis.
To remove the center-mounting brackets from the chassis:
- Loosen the screws from each bracket (see Figure 2).
- Remove each bracket.
