HARDWARE INSTALLATION
MOUNTING THE NVR300
The NVR300 can be placed on a flat surface such as a desktop or can be mounted into an equipment rack. Information about mounting the
NVR300 onto a desktop or into an equipment rack follows.
Mounting the NVR300 onto a Desktop
When mounting the NVR300 onto a desktop, ensure that rubber feet are installed on the NVR300. Position the unit to allow for cable and power
cord clearance at the rear of the unit.
Mounting the NVR300 into a Rack
The NVR300 mounts into an industry-standard 19-inch (48.26 cm) equipment rack. The NVR300 occupies 3 RUs (5.25 inches or 58.7 cm) of
vertical rack space. The hardware necessary to mount the NVR300 into a rack is supplied with the NVR300.
NOTE:
Allow 1 RU (1.75 inches or 4.5 cm) of space above the NVR300 for air circulation.
To install the NVR300 into a rack, refer to Figure 4 and do the following:
1. If chassis mounting brackets are not attached: Attach one mounting bracket to each side of the NVR300. Use five 10-32 x 0.25-inch Phillips
pan head screws for each bracket. Attach the brackets so the tapered ends are positioned toward the rear of the NVR300.
2. Remove the rubber feet from the underside of the unit if they are attached.
3. Attach one front-mount rail to one rear-mount rail. Make sure the rails are mounted back-to-back. Depending on rack depth, use either
three or four 8-32 x 0.375-inch Phillips truss head screws for each rail set. Leave the screws loose until step 10.
4. Repeat step 3 for the other rail set.
5. If you are installing the unit into a square-hole rack: Insert 16 cage nuts into the square-hole rack. Refer to Figure 4 and install them where
10-32 x 0.5 and 10-32 x 0.75 screws are shown.
6. Attach one support rail assembly to the equipment rack in the desired location, as follows.
NOTE:
The support rail assemblies are identical and may be used on either the right or left side of the rack.
a. Position the ear of the front-mount rail against the front of the equipment rack. Align the top and bottom holes in the ear of the rail
with the threaded holes (or cage nuts) in the rack.
b. Using two 10-32 x 0.5-inch Phillips flat head screws, attach the ear of the rail to the front of the rack. Insert the screws from the
outside of the rack, pointing toward the back of the rack.
c. Adjust the rails to the correct depth of the equipment rack by sliding the rear-mount rail to the back of the equipment rack.
d. Position the ear of the rear-mount rail against the rear exterior of the equipment rack. Align the top and bottom holes in the ear of the
rail section with the threaded holes (or cage nuts) in the equipment rack.
e. Using two 10-32 x 0.75-inch Phillips pan head screws, attach the ear of the rail to the rear of the rack. Insert the screws from the
outside of the rack, pointing toward the front of the rack.
7. Repeat step 6 for the second support rail assembly.
8. Attach one rack rail spacer to the front of the equipment rack, as follows.
a. Position the bottom hole of the spacer above the ear of the front-mount rail.
b. Insert two 10-32 x 0.5-inch Phillips flat head screws into the spacer, one in the top hole and one in the bottom hole. Leave the middle
hole empty; it will be used for securing the unit to the rack.
c. Tighten the two screws to secure the spacer to the rack.
9. Repeat step 8 for the second spacer.
10. Tighten the 8-32 x 0.375-inch Phillips truss head screws that were attached to the front- and rear-mount rails in steps 3 and 4.
11. Place the unit onto the mount rails by sliding the chassis brackets onto the rails. This step may require two people to lift and slide the unit
into place. The unit should slide in and out of the rack easily.
WARNING:
When sliding out the NVR300, be careful not to let the unit fall out of the rack.
12. After the unit is in place, install and tighten the four 10-32 x 0.75-inch Phillips pan head screws to secure the unit to the rack.
