The following space and airflow requirements are required for Network Automation NT-4000 system operation:

• Minimum clearance of 63.5 cm (25 in) in front of the rack
• Minimum clearance of 76.2cm (30 in) in the rear of the rack
• Minimum clearance of 121.9 cm (48 in) from the back of the rack to the back of another rack or row of racks

The Network Automation NT-4000 draws air in through the front of the chassis and expels air through the rear. Adequate ventilation is required to allow ambient room air to enter the chassis and to be expelled from the rear of the chassis.
To mount the appliance to a seismic rack, follow the instructions bundled with the rack-mounting kit in the NT-4000 Rev. 2 shipping box.

1. Unscrew the snap-in screws from the mounting rails and discard.
2. Install the round-hole M5 cage nuts in the appropriate rack hole positions where you want to install the appliance. Ensure that you install two cage nuts on the front and two on the back of each rail, as shown in Figure 5. Note that the square-hole cage nuts that ship with the accessory kit do not fit in the seismic rack.

3. Line up a mounting rail with the cage nuts, and attach the mounting rail to the rack with the M5 screws, ensuring that the front end of each mounting rail connects to the front of the rack.

Note: Ensure that both rail assemblies are correctly level!

4. Repeat steps 1 to 3 for the other mounting rail.

5. Slide out the side rails from each mounting rail and press the flange that holds each side rail in place. Then pull out each of the side rails from the assembly.

Make sure to keep track of the front end of each rail.

6. Align each side rail to the appliance and snap them in place.

7. With one person on each side, lift the appliance and position it in front of the rack.

8. Align the side rails on each side of the appliance with the mounting rails on the seismic rack.

9. Slide the appliance onto the mounting rails and into the rack. As you slide it into place, the catch mechanisms will click, indicating that you can safely withdraw the system from the rack without accidentally pulling it free.

10. Snap the Network Automation NT-4000 appliance into place, and fasten it to the rack using the retainer screws provided in the accessory kit. (For further information, refer to the instructions shipped with the accessory kit.)

11. Pull down the retention levers on both sides of the appliance, and insert the retainer screws on both sides, as indicated in Figure 6.

Powering On the Appliance

The Network Automation NT-4000 ships with two (2) hot-swappable redundant AC power supply modules. Infoblox recommends using the power cables shipped with the appliance to connect each power supply to separate power circuits. In the event of a power failure on one circuit, the appliance can then operate on the other.
To power the appliance:

• For each power supply, connect a power cable between the power connector on the back of the appliance and a properly grounded and rated power circuit that meets the provisions of the current edition of the National Electrical Code, or other wiring rules that apply to your location. Make sure that the outlet is near the appliance and is easily accessible.
