Oracle provides flexible mounting options for your Acme Packet 4900 equipment rack installation.

The mounting system consists of a slide rail mounted on each side of an equipment rack and a chassis slide rail mounted on each side of the Acme Packet 4900 chassis. Once the slide rails are installed on the equipment rack and chassis, the chassis can be slid into place by aligning the installed chassis slide rails along the guides on the equipment rack slide rails. When the Acme Packet 4900 is fully inserted into the equipment rack, it is secured in place with two captive thumbscrews.

In the first stage of system installation, secure the equipment rack slide rail to the equipment rack. The equipment rack slide rail can expand and contract to accommodate equipment racks of various depths up to 32”.

You can mount the equipment rack slide rail to both tapped hole rack and square rack. Follow the appropriate procedure below.

1. Locate the following components:
   • Assembled equipment rack slide rails (2)
   • #10-32 x 5/8” screws (8)
   • Mounting spacers (2)
2. Line up the equipment rack slide rail with an appropriate mount point on the front of the equipment rack.
   
3. For both holes in the flange, place one #10-32 x 5/8” screw through the mounting spacer, then through the slide rail flange and into the tapped hole.
   
4. Using a #2 Phillips head screwdriver, tighten the screws to secure the slide rail to the equipment rack. Do not completely torque the screws; leave a small amount of play at this time.
   
5. Expand and line up the equipment rack slide rail on the outside of the rear rack slide rail at the same height used for the front mount point.
   
6. For both holes in the slide rail flange, place one #10-32 x 5/8” screw through the flange and into the tapped hole, and screw them into place.
   
7. Repeat Steps 2 and 6 for the other test equipment slide rail.
   

1. Locate the following components included in the rail kit box:
   • Equipment rack slide rails (2)
   • #10-32 x 5/8” screws (8)
   • Mounting spacers (2)
   • Nut bars (2)
2. Line up the painted side of the stationary rail with an appropriate mount point on the front of the equipment rack.
   
3. For each of the two holes in the slide rail flange, place a #10-32 screw through the mounting spacer, then through the slide rail flange, and finally through the square hole in the rack rail.
   
4. Hold the nut bar behind the front rack rail.
5. Using a #2 Phillips head screwdriver, tighten the screws to secure the slide rail to the equipment rack. Do not completely torque the screws; leave a small amount of play at this time.
   
6. Expand and line up the unpainted side of the stationary rail flange on the outside of the rear rack rail at the height used for the front mount point.
   
7. Hold the nut bar behind the rear rack slide rail.
8. Place one #10-32 screw through each of the holes in the slide rail flange, then through the square hole in the rack, and finally into the nut bar.
9. Using a #2 Phillips head screwdriver, tighten the screws securely into place.
   
10. Torque the screws on the front and back of the rail slide.
11. Repeat this procedure for the other slide rail.

1. Locate the following components:
   • #6-32 x 1/4" flat head screws (6) (in accessory kit box)
   • Front-mounting flanges (2) (in accessory kit box)
   • #6-32 x 5/16" pan head screws (6) (in rail kit box)
   • Chassis slide rails (2) (in rail kit box)
   • #2 Phillips screwdriver
2. Line up one chassis flange with the tapped holes. Position the chassis flange’s spring-loaded thumbscrew toward the front panel of the system.
   
3. Insert 2 x #6-32 x 5/16" flat head screws into the flange and chassis, and using a #2 Phillips screwdriver, tighten the screws to secure the flange to the chassis.
   
4. Line up the chassis slide rail with the Acme Packet 4900 side panel. Position hole #4 closest to the flange at the front of the Acme Packet 4900 chassis. Line up the keyhole slot on the slide rail with the keyhole button on the side of the Acme Packet 4900 and slide the rail slightly backwards to secure the slide. When you do this, holes #4, #2, and #3 on the slide will line up with the corresponding tapped holes on on the chassis.
   
5. Use #6-32 x 5/16" screws to secure the chassis slide rail to the side of the Acme Packet 4900.
   
6. Repeat this procedure for the other side of the Acme Packet 4900 chassis.

1. Lift the Acme Packet 4900 into the correct position to prepare to be installed into the equipment rack.
2. Line up the chassis slide rails in back of the chassis with the guides in front of the equipment rack slide rails.
   
3. If necessary, press in the latches on either side of the Acme Packet 4900 in order for the assembly to slide into the guides.
4. Push the Acme Packet 4900 fully into the equipment rack.
5. Line up the chassis-mounted thumbscrews with the threads on the Acme Packet 4900 mounting spacer. You may have to adjust the spacer locations before they line up with the Acme Packet 4900’s captive screws.
   
6. Once correctly positioned, hand-tighten the thumbscrews into the mounting spacer and secure the chassis in the rack.
7. Torque the two captive thumbscrews using a #2 Phillips screwdriver.
8. Torque all four #10-32 x 5/8” front screws that hold the slide rails to the rack.
