Installing the NAE/NIE

Introduction

The Network Automation Engine (NAE)/Network Integration Engine

(NIE) monitors and supervises networks of devices that typically

control Heating, Ventilating, and Air Conditioning (HVAC)

equipment, lighting, security, and building access. The NAE/NIE unit

is delivered with the operating system software already installed, but

the user needs to provide site-specific data. Through a standard Web

browser interface, the NAE/NIE provides features including alarm and

event management, trending, archiving, energy management, data

exchange, scheduling, dial features, and password protection.

This technical bulletin describes the hardware features of the

NAE/NIE and how to:

•mount the NAE/NIE

•install the data protection battery

•wire the NAE/NIE

•turn off the NAE/NIE

NAE Ports

Power

The NAE requires 24 VAC power. The minimum input voltage for the

NAE to operate properly is 20 VAC, but a minimum of 22 VAC is

recommended to prevent nuisance power shutdown and startup

routines during brownout conditions. When the input voltage falls

below the 22 VAC, the NAE initiates a shutdown routine, storing

operations data in the nonvolatile memory for protection through the

power failure. Maximum power consumption is 50 VA.

Connect 24 VAC power to terminals 1 and 3 (see Figure 2). You can

remove line power by removing the power terminal block from the

NAE.

Figure 2: Power Hookup

Note: When you remove line power, the NAE is still powered by

the battery and it takes approximately 1 to 6 minutes for the NAE to

completely power down, depending on the size of the database. The

NAE unit is completely powered down when the POWER LED is off.

See Wiring the NAE in this document for more information on the

power connection.

Note: In North America, use an AS-XFR100-1 or AS-XFR010-1

100 VA power transformer to provide adequate power. We do not

recommend that the transformer share its load with other devices.

Outside North America, use a safety-isolating transformer at the

appropriate rating. These transformers are robust units, which provide

proper operating conditions and limit noise problems.

N2 Bus Ports (N2 A, N2 B) (NAE Only)

The two N2 connections on the NAE are 4-pin removable, keyed

terminal blocks (Figure 3). See the System Configuration Tool

Technical Bulletin (LIT-1201534) for more information on using the

NAE with N2 networks.

Installing the NAE/NIE Technical Bulletin 7

Use port A to connect directly to a Personal Computer (PC) serial port

to browse to the NAE. See the Direct Connect and Dial-Up Connection

on Windows® 2000 or Windows XP Operating Systems Application

Note (LIT-1201639). Use Port B to connect with a VT100 terminal or

PC using a VT100 terminal emulator because Port B outputs the device

Internet Protocol (IP) address. See the Configuring the Network

Automation Engine (NAE) Technical Bulletin (LIT-1201519).

USB Ports (USB A and USB B)

The two USB ports are configured as masters and are independent of

each other. USB A and USB B support the pinouts in Figure 5.

Figure 5: USB Port

It is possible to connect an external modem with a USB slave port

connection to one of the USB ports. External modems are

recommended for easy replacement especially in lightning-prone

areas. The external modem does not protect against lightning but

offers a fast fix for a unit with a damaged internal modem. Two

modem drivers are pre-installed on the NAE: the Zoom® Telephonics

2985 modem and Multi Tech® MT5634ZBA-USB modem.

For information on configuring an external or internal modem, see the

Configuring the NAE Technical Bulletin (LIT-1201519).

On 1 second, Off 1 second = NAE software is in startup mode.

On 0.5 seconds, Off 0.5 seconds = NAE software is shutting down.

Off Steady = Operating system is shutting down or software is not running.

24 VAC

(GREEN)

On Steady On Steady = 24 VAC power present

Off Steady = Loss of 24 VAC power. In the Off Steady condition, the NAE can be

running on battery power. Also see the POWER LED.

BATT FAULT

(RED)

Off Steady On Steady = Battery fault. Replace the battery.

GENL FAULT

(RED)

Off Steady On Steady = General Fault. Fault conditions include excessive Central

Processing Unit (CPU), flash or memory use, or excessive CPU or Printed Wire

Board (PWB) temperature. In normal operation, the GENL FAULT LED stays on

steady for the first half of the startup sequence.

Installing the NAE/NIE Technical Bulletin10

During startup, the NAE automatically runs an LED test to verify the

operational status of the LEDs. Immediately after a start, the LED

lighting sequence occurs as follows:

1. The PEER COM, RUN, and GENL FAULT LEDs turn on,

indicating that the Operating System (OS) is booting up. For the

NAE, the N2A and N2B LEDs also turn on.

2. The N2A, N2B, PEER COM, RUN, and GENL FAULT LEDs

shut off. The RUN LED flashes to indicate that the NAE software

is loading.

3. The operational status of the NAE displays (see Table 1). When

the RUN LED goes On Steady, the application is running and the

unit is ready.

The total time to power up the NAE depends on the size of the

database and can take is several minutes. Figure 7 shows the locations

of the LEDs.
