Installing the Network Automation NT-4000
Note:
The Network Automation NT-4000 system must be installed in a four-post seismic rack.
The Network Automation NT-4000 appliance ships with mounting rails, side rails, and an accessory kit that contains
mounting hardware. To mount the appliance to a seismic rack, you also need the following:
•
M5 rack screws that fit the seismic rack
•
Round-hole M5 cage nuts for use with the seismic rack
•
A screwdriver
Rack Mounting Safety Requirements
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.
