Mounting
Location considerations
Follow these guidelines when mounting a network engine:
• Ensure that the mounting surface can support the network engine and any user-supplied
enclosure.
• Mount the network engine in proper orientation (Figure 1).
• Mount the network engine on an even surface in wall mount applications whenever possible. If
you must mount the network engine on an uneven surface, be careful not to crack the mounting
clips or network engine housing when tightening the screws. Use shims or washers to mount the
network engine evenly on the mounting surface.
• Mount the network engine in areas free of corrosive vapors, and observe the environmental
section.
• Allow sufficient space for cable and wire connections and access to the data protection battery
and End-of-Line (EOL) switch (Figure 1).
• Do not mount the network engine where the ambient temperature may exceed 50°C (122°F).
• Do not mount the network engine on surfaces prone to vibration or in areas where
electromagnetic emissions can interfere with network engine communication.
• Do not obstruct the network engine housing ventilation holes.
• Do not mount power transformers below the network engine.
On applications where the network engine is mounted inside a panel or enclosure, follow these
additional guidelines:
• Do not install the network engine in airtight enclosures.
• Do not install heat-generating devices in the enclosure with the network engine that may cause
the ambient temperature to exceed 50°C (122°F).
Mounting the Network Engine
Wall mount applications
Use the holes in the three mounting clips for wall mount applications.
To mount the network engine on a vertical surface:
1. Ensure that all three mounting clips are inserted into the back of the network engine housing,
pulled outward, and snapped firmly into the extended position (Figure 3).
2. Mark the location of the three wall mount holes using the dimensions in Figure 2, or hold the
network engine up to the wall as a template and mark the locations.
3. Drill holes in the wall at the locations marked in (Figure 2) and insert wall anchors (if
necessary).
