Application
The Metasys Network Automation Engine (NAE) is an
Ethernet-based, supervisory device that connects BAS
networks to IP networks. NAEs monitor and control
field-level building automation devices, including HVAC
equipment, lighting, security, and fire safety equipment.
At Release 11.0, the NAE55 is also FIPS 140-2 Level 1
compliant. FIPS 140-2 is a United States government
cybersecurity standard that approves cryptographic
modules/algorithms used for encryption. Use this
document to install the NAE. Figure 1 shows the NAE55
engine.

The NAE offers various integration options. Ethernet
network integrations include the following options:
• Johnson Controls and 3rd party BACnet/IP, BACnet/SC
devices
• Simplex
Fire Alarm Control Unit (FACU)

NAE55 Installation Guide
Important: For any other custom integrations,
contact your local Systems Integration Services
(SIS) team before an upgrade. Updated drivers are
available on request.
In this installation guide, the term network engine
applies to any NAE55 model, unless otherwise stated.
For installation instructions on the NAE55s that are
approved for Metasys system smoke control applications,
refer to the NAE55 Installation Instructions (Part No.
24-10051-00132).
Note: At Metasys Release 10.0 and later, modems
(internal and external) and pagers are no longer
supported on NAE55 engines that run the Linux
operating system, but are still supported on
prior releases for engines that use a Windows
Embedded operating system. You can field-upgrade
a network engine at Release 9.0 that has an internal
modem to Release 10.0 or later to acquire new
release enhancements, but its modem and pager
functionality are lost. If you need modem and pager
functionality, do not upgrade the NAE55 engine to
Release 10.0 or later.
Installation
Follow these guidelines when installing the network
engine:
• Transport the network engine in the original container
to minimize vibration and shock damage to the network
engine.
• Verify that all the parts shipped with the network
engine. The data protection battery and network engine
ship together but are packaged separately.
• Do not drop the network engine or subject it to physical
shock.
• Do not open the network engine housing (except the
data protection battery compartment). The network
engine has no user-serviceable parts inside.
Parts included
• one MS-NAE55xx-x model
• one data protection battery
• one installation instructions sheet
Materials and special tools needed
You can mount the network engine by using the fasteners
option or the DIN rail option.
• Fasteners option - Three fasteners appropriate for the
mounting surface:
- #8 screws - North America
- M4 screws - Europe
• DIN rail option - 36 cm (14 in.) or longer section of 35
mm (1 1/8 in.) for DIN rail mount applications only.
