NAE-S Installation Guide
Application (For United States and
Canada)
The secure Network Automation Engine (NAE-S) is a web-
enabled, Ethernet-based, supervisory device that monitors
and controls networks of field-level building automation
devices, including HVAC equipment, lighting, security, and
fire safety equipment. This document describes how to
install an NAE-S (MS-NAE551S-2).
The NAE-S is hardened version of the standard NAE55 that
uses embedded encryption technology to protect and
secure the building management system at the endpoint.
The engine meets the Federal Information Processing
Standard (FIPS 140-2), Security Level 2, that specifies the
use of a cryptographic module and a tamper-proof cover.
The NAE-S is also Common Criteria certified. Figure 2
shows the NAE-S model.

Installation
Follow these guidelines when installing an NAE-S:
• Transport the NAE-S in the original container to
minimize vibration and shock damage to the engine.
• Verify that all the parts shipped with the NAE-S. The
data protection battery and NAE-S ship together but are
packaged separately.
• Do not drop the NAE-S or subject it to physical shock.
• Do not open the NAE-S housing during installation.
