Overview

The EMX provides a rack management solution that combines the capabilities

of environmental monitoring, asset management, image surveillance, event

notifications and support for Schroff

®

heat exchangers.

Asset management:

You can remotely track the location of IT equipment after tagging IT

devices electronically. This feature is especially useful when there are

hundreds of IT devices to administer.

The following items are required for setting up the asset management

system:

▪ Raritan asset tags: You tag an IT device by sticking an electronic asset

tag on it.

▪ Raritan asset management strips (asset strips): Each asset strip

transmits the tag and position information to the EMX.

▪ An EMX device: You can remotely locate each tagged IT device through

the EMX.

Environmental monitoring and/or system control:

After connecting Raritan environmental sensor packages to the EMX, you

can remotely monitor environmental conditions, such as temperature or

humidity in the data center, or control a system if actuators are connected.

Image surveillance:

With a Logitech

®

webcam connected, a simple camera and video

surveillance system is established so that you can remotely view real-time

snapshots or videos of the data center.

Event notifications:

Event rules and actions that are triggered when an event occurs are

supported by the EMX.

Chapter 1

Introduction

Chapter 1: Introduction

2

Email messages, log events, syslog messages, webcam snapshots, SNMP

traps and SMS messages can be triggered when the events you define

occur.

In addition, images captured by the webcam can be emailed to users in

response to a specific event.

Integration with Schroff

®

LHX/SHX heat exchangers:

The EMX can integrate with a Schroff

®

LHX-20, LHX-40 and SHX-30 heat

exchanger, which draws warm air into the air/water heat exchanger to cool

the air. This integration provides a solution for remotely monitoring the

heat exchanger.

Product Models

There are two EMX models:

• EMX2-111

• EMX2-888

All models are functionally identical, but vary in the dimension and total

number of ports.

Note: For a list of available asset strip kits and tags, visit the Raritan website's

Product Selector page (http://www.findmypdu.com/).

EMX2-111

EMX2-111 has the following ports and components:

• 1 Sensor port

• 1 Feature port

• 1 RS-485 port

• 2 USB ports (1 USB-A and 1 USB-B)

• 1 RS-232 port

• 1 Ethernet port

• 1 LCD display

• Control buttons

For details on each port, see Connection Ports (on page 66).

EMX2-888

Chapter 1: Introduction

3

EMX2-888 has the following ports and components:

• 8 Sensor ports

• 8 Feature ports

• 8 RS-485 ports

• 3 USB ports (2 USB-A and 1 USB-B)

• 1 RS-232 port

• 1 Ethernet port

• 1 LCD display

• Control buttons

• Contact closure sensor termination

For details on each port, see Connection Ports (on page 66).

Note: If your EMX is EMX2-888, which contains built-in contact closure sensor

terminals, see Connecting Contact Closure Sensors to OLD EMX2-888 (on page

603) and Connecting Contact Closure Sensors to EMX2-888 (on page 80),

respectively, based on your device type.

Package Contents

The following describes the equipment shipped with an EMX device. If anything

is missing or damaged, contact the local dealer or Raritan Technical Support for

help.

• The EMX device

• Power cord

• Bracket pack and screws

• Asset strips (optional)

• Asset tags (optional)

APIPA and Link-Local Addressing

EMX supports Automatic Private Internet Protocol Addressing (APIPA).

With APIPA, your EMX automatically configures a link-local IP address and a

link-local host name when it cannot obtain a valid IP address from any DHCP

server in the TCP/IP network.

Only IT devices connected to the same subnet can access the EMX using the

link-local address/host name. Those in a different subnet cannot access it.

Exception: EMX in the Port Forwarding mode does not support APIPA. See

Setting the Cascading Mode (on page 173).

Once the EMX can get a DHCP-assigned IP address, it stops using APIPA and the

link-local address is replaced by the DHCP-assigned address.

Scenarios where APIPA applies:

• DHCP is enabled on the EMX, but no IP address is assigned to the EMX.

This may be caused by the absence or malfunction of DHCP servers in the

network.

Note: Configuration by connecting the EMX to a computer using a network

cable is an application of this scenario. See Connecting the EMX to a

Computer (on page 18).

• The EMX previously obtained an IP address from the DHCP server, but the

lease of this IP address has expired, and the lease cannot be renewed, or

no new IP address is available.

Link-local addressing:

• IPv4 address:

Factory default is to enable IPv4 only. The link-local IPv4 address is

169.254.x.x/16, which ranges between 169.254.1.0 and 169.254.254.255.

• IPv6 address:

A link-local IPv6 address is available only after IPv6 is enabled on the EMX.

See Configuring Network Settings (on page 158).

• Host name - pdu.local:

You can type https://pdu.local to access the EMX instead of typing the

link-local IP address.

Retrieval of the link-local IPv4 address:

• See IPv4 Address (on page 75).

Before You Begin

Prepare the installation site. Make sure the installation area is clean and not

exposed to extreme temperatures or humidity. Allow sufficient space around

the EMX for cabling and equipment connections.

6

Depending on the model you purchased, the way to mount an EMX device

varies.

Mounting a 1U EMX .............................................................................................. 7

Mounting a Zero U EMX

This section describes how to mount a Zero U EMX device using L-brackets and

two buttons.

To mount Zero U models using L-brackets and two buttons:

1. Align the two edge slots of the L-bracket with the two screw holes on the

top of the EMX device.

2. Screw the L-bracket to the device and ensure the bracket is fastened

securely.

3. Repeat Steps 1 to 2 to screw another L-bracket to the bottom of the

device.

4. After both L-brackets are installed, you can choose either of the following

ways to mount the device in the rack.

Chapter 2

Rack Mounting an EMX

Chapter 2: Rack Mounting an EMX

▪ Using rack screws, fasten the device to the rack through two identical

holes near the edge of each L-bracket.

▪ Mount the device by screwing a mounting button in the back center of

each L-bracket and then having both buttons engage the mounting

holes in the rack. The recommended torque for the button is 1.96 N·m

(20 kgf·cm).

Mounting a 1U EMX

Using the appropriate brackets and tools, fasten the 1U EMX device to the rack

or cabinet.

To mount the 1U EMX device:

1. Attach a rackmount bracket to both sides of the EMX with the provided

screws.

2. Insert the cable-support bar into rackmount brackets.

Chapter 2: Rack Mounting an EMX

3. Secure with the provided end cap screws.

4. Fasten the rackmount brackets' ears to the rack using your own fasteners.
