Johnson Controls NAE45 - User Manual

NAE35/NAE45 Installation Guide
Application
The Network Automation Engine (NAE) is a web-enabled, Ethernet-based, supervisory device that
monitors and controls networks of field-level building automation devices, HVAC equipment, and
lighting.
This document describes how to install NAE35 and NAE45 models, which are referred to collectively
as network engines, unless otherwise specified. These network engines provide integration to the
following network protocols: BACnet/IP, BACnet MS/TP, N2 Bus, and integrations to other building
management communication technologies, including Modbus®, M-Bus, and KNX. At Release
9.0, the Modbus, M-Bus, and KNX integrations are added and licensed during network engine
commissioning. At Release 9.0.7, the Modbus, M-Bus, and KNX integrations are included with the
image of the network engine, already pre-licensed and ready for selection during commissioning.
Important: For existing custom integrations, contact your local Systems Integration Services
(SIS) team before an upgrade. Updated drivers can be provided on request.
Note:
Beginning with Metasys Release 9.0.7, modems (internal and external) and pagers are no
longer supported on NAE35 and NAE45 engines that run the Linux operating system, but are
still supported on prior releases for engines that use a Windows Embedded operating system.
If you receive from the factory a network engine with Release 9.0 that has an internal modem,
you can field-upgrade the engine to Release 9.0.7 to acquire new release enhancements, but
its modem and pager functionality is lost. If you need modem and pager functionality, do not
upgrade the NAE35 or NAE45 engine to Release 9.0.7.
In addition, support for the LonWorks® network is no longer available on the NAE35 and
NAE45 engines at Release 9.0.7. Therefore, do not upgrade to Release 9.0.7 any NAE35 or
NAE45 engine that features the LonWorks integration.
Note: If you receive an NAE35 or NAE45 engine from the factory that is imaged with Release
9.0, you can field-upgrade the engine to Release 9.0.7 if the upgrade is supported.
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.
• 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 NAE35 or NAE45 with removable terminal plugs
• one data protection battery (installed and connected when the network engine is shipped)
• one Installation Instructions sheet
