Overview
The EMX device provides a rack management solution that combines
both asset management and environmental monitoring capabilities.
With asset management capability, you can remotely track the location of
IT equipment after tagging the 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 an asset management
system:
Raritan asset tags: You tag an IT device by sticking an electronic
asset tag on it
Raritan asset management sensors (asset sensors): Each asset
sensor transmits the tag and position information to the EMX device
An EMX device: You can remotely locate each tagged IT device
through the EMX device.
With Raritan environmental sensors connected to the EMX device, you
can remotely monitor environmental conditions such as temperature or
humidity in the data center or server room.
With a Logitech® QuickCam® Pro 9000 webcam connected, a simple
camera and video surveillance system is built, displaying the real-time
snapshots or videos inside the server room or data center to enhance
monitoring and security.
Events and actions that are triggered when an event occurs are
supported by the EMX. Specifically, email messages, log events, syslog
messages, webcam snapshots, SNMP traps and SMS messages can be
triggered when the events you define occur. Custom messages can be
configured for email messages, and images captured by the webcam
can be sent to users via email.
In addition, the EMX device integrates with a Schroff® LHX-20 or LHX-40
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. EMX can also be used in conjunction
with Raritan's data center management application, dcTrack™.
This user guide describes the following models:
EMX2-111
EMX2-888

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 on the device, you can choose
either of the following ways to mount the device in the rack.
Using rack screws, fasten the device to the rack through two
identical holes near the edge of each L-bracket.
Chapter 2: Installing and Configuring the EMX Device
9
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 Device
Using the appropriate brackets and tools, fasten the 1U EMX device to
the rack or cabinet.
To mount the 1U EMX device:
1. Attach one rackmount bracket to one side of the EMX device.

Connecting the EMX to a Power Source
If your EMX device is designed to use a cable retention clip, install the
clip before connecting a power cord. A cable retention clip prevents the
connected power cord from coming loose or falling off.
The use of cable retention clips is highly recommended for regions with
high seismic activities, and environments where shocks and vibrations
are expected.
To connect the EMX device to a power source:
1. Install the cable retention clip by inserting both ends into the tiny
holes on two hexagon screws adjacent to the power socket.
2. Plug one end of the Raritan-provided power cord into the power
socket, and press the cable retention clip toward the power cord until
it holds the cord firmly.
3. Connect the other end of the power cord to an appropriate power
source.
Configuring the EMX
To configure the EMX device:

3. Configure the EMX device using the command line interface.
Connecting the EMX to a Computer
To configure the EMX using a computer, it must be connected to the
computer with an RS-232 serial interface. The computer must have a
communications program such as HyperTerminal or PuTTY.
If your computer does not have a serial port, use a regular USB cable to
connect the EMX to the computer for initial configuration. The EMX
device can emulate a USB-to-serial converter after the USB-to-serial
driver is properly installed in the Windows® operating system.
Note: Not all serial-to-USB converters work properly with the EMX device
so this section does not introduce the use of such converters.
Now connect the EMX to a computer for initial configuration by following
either of the following procedures.
To make a serial connection:
1. Connect one end of the null-modem cable to the RS-232 port labeled
CONSOLE / MODEM on the EMX.
2. Connect the other end of the null-modem cable to the serial port
(COM) on the computer.
To make a USB connection:
1. Connect one end of a regular USB cable to the USB-B port on the
EMX.
2. Connect the other end of the USB cable to the USB-A port on the
computer.
Installing the USB-to-Serial Driver
The EMX can emulate a USB-to-serial converter over a USB connection.
A USB-to-serial driver named "Dominion Serial Console" is required for
Microsoft® Windows® operating systems. Download the dominion-
serial.zip driver file, which contains dominion-serial.inf and dominionserial-setup.exe files, from the Raritan website http://www.raritan.com
under the Firmware and Documentation http://www.,
http://www.raritan.com/support/firmware-and-documentation/
section for the EMX.
To install the driver in Windows® Vista and 7:
1. Disconnect the EMX's USB cable from the computer.
Chapter 2: Installing and Configuring the EMX Device

2. Run dominion-serial-setup.exe. A Dominion Serial Console Driver
Setup Wizard appears.
3. Click Install to install the driver.
4. Click Finish when the installation is complete.
5. Connect the EMX's USB cable to the computer. The driver is
automatically installed.
To install the driver in Windows® XP:
1. Disconnect the EMX's USB cable from the computer.
2. Check if the file "usbser.sys" is available in
C:\Windows\ServicePackFiles\i386. If not, extract it from the
Windows installation CD disc, and copy it to the same directory
where the USB-to-serial driver is stored.
On a CD disc with SP3 included, it is extracted from
I386\SP3.CAB.
On a CD disc with SP2 included, it is extracted from
I386\SP2.CAB.
On a CD without an SP, it is extracted from I386\DRIVER.CAB.
3. Connect the EMX's USB cable to the computer.
4. The computer detects the new device and the "Found New Hardware
Wizard" dialog appears. If this dialog does not appear, choose
Control Panel > System > Hardware > Device Manager, right-click
the Dominion Serial Console, and choose Update Driver.
5. Select "Install from a list or specific location," and specify the location
where the driver is stored.
6. If you see the message requesting the file "usbser.sys," specify the
location of the file.
7. The installation is complete.
In Linux:
No additional drivers are required, but you must provide the name of the
tty device, which can be found in the output of the "dmesg" after
connecting the EMX to the computer. Usually the tty device is
"/dev/ttyACM#" or "/dev/ttyUSB#," where # is an integer number.
For example, if you are using the kermit terminal program, and the tty
device is "/dev/ttyACM0," perform the following commands:
> set line /dev/ttyACM0
> connect

Combining Asset Sensors
Number
Item
8U MASTER asset sensor with 8 tag ports
8U SLAVE asset sensor with 8 tag ports
5U "ending" SLAVE asset sensor with 5
tag ports
Each tag port on the asset sensors corresponds to a rack unit and can
be used to locate the IT devices on a specific rack (or cabinet). For each
rack, you can attach asset sensors up to 64U long, consisting of one
MASTER and multiple SLAVE asset sensors. The difference between
the master and slave asset sensors is that the master asset sensor has
an RJ-45 connector while the slave one does not.
The following diagram illustrates some asset sensors. Note that Raritan
provides more types of asset sensors than the diagram.
Note: Unlike regular slave asset sensors, which have one DIN connector
respectively on either end, the ending slave asset sensor has one DIN
connector on only one end. An ending asset sensor is installed at the
end of the asset sensor assembly.
To assemble asset sensors:
1. Connect a MASTER asset sensor to an 8U SLAVE asset sensor.
Plug the white male DIN connector of the slave asset sensor into
the white female DIN connector of the master asset sensor.
Chapter 2: Installing and Configuring the EMX Device
23
Make sure that the U-shaped sheet metal adjacent to the male
DIN connector is inserted into the rear slot of the master asset
sensor. Screw up the U-shaped sheet metal to reinforce the
connection.
2. Connect another 8U slave asset sensor to the one being attached to
the master asset sensor in the same manner as Step 1.
3. Repeat the above step to connect more slave asset sensors. The
length of the asset sensor assembly can be up to 64U.
The final asset sensor can be 8U or 5U, depending on the actual
height of your rack.
Using the "ending" asset sensor as the final asset sensor is
strongly recommended.
4. Vertically attach the asset sensor assembly to the rack, next to the IT
equipment, making each tag port horizontally align with a rack unit.
The asset sensors are automatically attracted to the rack because of
magnetic stripes on the back.
Note: The asset sensor is implemented with a tilt sensor so it can be
mounted upside down.

10-meters of cable connecting each asset sensor assembly.
4. Connect the other end of the Cat5e/6 cable into the in-line Cat5e/6
connector on the X-cable.
5. Connect the ethernet end of the X-cable into the FEATURE port on
the EMX-111 device.
6. Plug the sensor cable of the X-cable into the SENSOR port on the
EMX-111. This supplies power to the asset sensor assembly from
the SENSOR port via the Cat5e/6 cable.
Note: If sensors need to be connected to the EMX via the SENSOR
port, plug them into the SENSOR connector on the X-cable. If no
sensors are connected, this connector can remain empty.
7. Configure the asset sensor. See Configuring the Asset Sensor (on
page 330).
All LEDs on the asset sensor assembly may cycle through different
colors during the power-on process if the asset sensor's firmware is
being upgraded by the EMX device. After the power-on or firmware
upgrade process completes, the LEDs show solid colors. Note that the
LED color of the tag ports with asset tags connected will be different from
the LED color of the tag ports without asset tags connected.

Note: Each tag port on the blade extension strip is labeled a number,
which is displayed as the slot number in the EMX's web interface.
To install a blade extension strip:
1. Connect the tag connector cable to the blade extension strip.
Plug the cable's connector into the socket at either end of the
blade extension strip.
2. Move the blade extension strip toward the bottom of the blade
chassis until its mylar section is fully under the chassis, and verify
that the blade extension strip does not fall off easily. If necessary,
you may use the adhesive tape in the back of the mylar section to
help fix the strip in place.
3. Connect one end of an asset tag to a blade server and connect the
other end to the blade extension strip.
a. Affix the adhesive part of the asset tag to one side of a blade
server through the tag's tape.
Chapter 2: Installing and Configuring the EMX Device
32
b. Plug the tag connector of the asset tag into the tag port on the

4. Repeat the above step until all blade servers in the chassis are
connected to the blade extension strip via asset tags.
5. Plug the tag connector of the blade extension strip into the closest
tag port of the asset sensor assembly or the AMS-M2-Z asset sensor
on the rack.
Note: If you need to temporarily disconnect the tag connector of the
blade extension strip, wait at least 1 second before connecting it back, or
the EMX may not detect it.
Chapter 2: Installing and Configuring the EMX Device
33
Connecting Environmental Sensors (Optional)
To enable the detection of environmental factors around the EMX,
connect one or more Raritan environmental sensors to the EMX device.
The maximum distance for all sensor cabling plugged into the product's
sensor port should not exceed 30 meters/100 feet. Contact Raritan
Technical Support if you have questions.
If a Raritan sensor hub is used, you can connect up to 16 environmental
sensors per SENSOR port. That is,
For EMX2-111, which has only 1 SENSOR port, a maximum of 16
environmental sensors can be connected.
For EMX2-888, which has 8 SENSOR ports, a maximum of 128
environmental sensors can be connected. Since the EMX2-888
device is implemented with two channels of onboard contact closure
termination, it supports a maximum of 130 environmental sensors.
Each SENSOR port can only support a maximum of two Raritan contact
closure sensors, which has the shortest update interval among all
Raritan sensors. See Information about Update Interval (on page
177).
Note that a Raritan environmental sensor usually contains more than one
sensor. For example, a DPX-T2H2 counts as 4 sensors, and a DPXT3H1 counts as 4 sensors.
Warning: For proper operation, wait for 15~30 seconds between each
connection operation or each disconnection operation of
environmental sensors.
To directly connect one or multiple environmental sensors:
Plug the connector of the environmental sensor into the SENSOR
port on your EMX device.
Note: Depending on the model you purchased, the total number of
SENSOR ports varies.
To connect environmental sensors via an optional PX sensor
hub:
1. Connect a Raritan sensor hub to the EMX device.
a. Plug one end of the Raritan-provided phone cable (4-wire, 6-pin,
RJ-12) into the IN port (Port 1) of the hub.
b. Plug the other end into one of the SENSOR ports on the EMX
device.

Feature Port X-Cable instead of the SENSOR port on the EMX-111.
2. Connect Raritan environmental sensors to any of the four OUT ports
on the hub.
Raritan sensor hubs CANNOT be cascaded so at most a sensor hub
can be connected to each SENSOR port on the EMX device. This
diagram illustrates a configuration with a sensor hub connected.
3. If there are any Raritan air flow sensors attached, make sure that
sensor faces the source of the wind (such as a fan) in the
appropriate orientation as indicated by the arrow on that sensor.
4. Configure the environmental sensor. See Configuring
Environmental Sensors (on page 172).

About Contact Closure Sensors
Raritan's contact closure sensor (DPX-CC2-TR) can detect the openand-closed status of the connected detectors/switches.
This feature requires the integration of at least a discrete (on/off)
detector/switch to work properly. The types of discrete
detectors/switches that can be plugged into DPX-CC2-TR include those
for:
Door open/closed detection
Door lock detection
Floor water detection
Smoke detection
Vibration detection
Raritan does NOT produce most of the above detectors/switches except
floor water sensors. When using third-party probes, you must test them
with Raritan's DPX-CC2-TR to ensure they work properly.
Important: Integration and testing for third-party detectors/switches
is the sole responsibility of the customer. Raritan cannot assume
any liability as a result of improper termination or failure (incidental
or consequential) of third-party detectors/switches that customers
provide and install. Failure to follow installation and configuration
instructions can result in false alarms or no alarms. Raritan makes
no statement or claim that all third-party detectors/switches will
work with DPX-CC2-TR.
Connecting Third-Party Detectors/Switches
There are two ways to connect third-party detectors/switches to the EMX
device:
Connect the detectors/switches to DPX-CC2-TR, which will be
connected to a SENSOR port on the EMX device
Connect the detectors/switches to the contact closure sensor
termination on the EMX device if your EMX device is EMX2-888
Chapter 2: Installing and Configuring the EMX Device
36
Connecting Detectors/Switches to DPX-CC2-TR
A DPX-CC2-TR unit provides two channels for connecting two discrete
(on/off) detectors/switches. There are four spring-loaded termination
points on the body of DPX-CC2-TR: the two to the right are associated
with one channel (as indicated by the LED number), and the two to the
left are associated with the other. You must plug discrete
detectors/switches into these termination points.
To connect third-party or Raritan's discrete detectors/switches:
1. Strip the insulation around 12mm from the end of each wire of
discrete detectors/switches.
2. Press and hold down the tiny rectangular buttons above the
termination points on the body of DPX-CC2-TR.
Note: Each button controls the spring of each corresponding
termination point.
3. Fully insert each wire of both detectors/switches into each
termination point.
Plug both wires of a detector/switch into the two termination
points to the left.
Plug both wires of the other detector/switch into the two
termination points to the right.
4. Release the tiny rectangular buttons after inserting the wires
properly.
5. Verify that these wires are firmly fastened.
6. If any detector/switch plugged into the contact closure sensor is

Configuring a Contact Closure Sensor
Before using DPX-CC2-TR to detect the contact closure status, water,
smoke or vibration, you must determine the normal state by adjusting its
dip switch, which controls the LED state on the body of DPX-CC2-TR. A
dip switch is associated with a channel.
To adjust the dip switch setting:
1. Place the detectors/switches connected to DPX-CC2-TR to the
position where you want to detect a specific environmental situation.
2. Uncover the dip switch on the body of DPX-CC2-TR.
3. To set the Normal state for channel 1, locate the dip switch labeled
1.
4. Use a pointed tip such as a pen to move the slide switch to the end
labeled N.O or N.C.
The side labeled N.O (Normally Open): The open status of the
connected detector/switch is considered normal. This is the
default.
The side labeled N.C (Normally Closed): The closed status of the
connected detector/switch is considered normal.
For Raritan's water sensors, the Normal state should be Normally
Open, which indicates there is no water detected. Adjust the dip
switch setting to Normally Open and verify that the LED of the
channel where the Raritan's water sensor is connected remains OFF.
5. To set the Normal state for channel 2, repeat Step 4 for adjusting the
other dip switch's setting.
6. Install back the dip switch cover.
Chapter 2: Installing and Configuring the EMX Device
38
Note: The dip switch setting must be properly configured, or the sensor
LED may be incorrectly lit in the Normal state.
Connecting Third-Party Detectors/Switches to the EMX
A specific EMX model (EMX2-888) provides two channels of contact
closure sensor termination points, allowing for direct connection of thirdparty contact closure detectors/switches.
It is not guaranteed that all third-party detectors/switches are
compatible with the EMX device. You need to test the compatibility
after properly installing them.
To connect third-party detectors/switches:
1. Strip the insulation around 12mm from the end of each wire of
discrete detectors/switches.
2. Press and hold down the tiny rectangular buttons above the
termination points.
Note: Each button controls the spring of each corresponding
termination point.
3. Fully insert each wire of both detectors/switches into each
termination point.
Plug both wires of a detector/switch into the two termination
points to the left.

termination points to the right.
4. Release the tiny rectangular buttons after inserting the wires
properly.
5. Verify that these wires are firmly fastened.
6. By default the open status of the detector/switch is considered
normal. To set the "normal" setting to "closed" , press down the
corresponding button adjacent to the termination points.
Contact Closure Sensor LEDs
Two LEDs are located near the contact closure termination points on the
EMX device or Raritan contact closure sensor module (DPX-CC2-TR).
Each LED shows the state of the corresponding channel.
The LED is lit when the associated detector/switch is in the "abnormal"
state, which is the opposite of the Normal state.
The meaning of a lit LED varies depending on the Normal state settings.
When the Normal state is set to Normally Closed (N.C):
When the Normal state is set to Normally Open (N.O):

Readings Highlighted in Yellow or Red
Color
State
White
The background is white in one of the following scenarios:
For a numeric sensor, no thresholds have been
enabled.
If any thresholds have been enabled for a numeric
sensor, the sensor reading is between the lower and
upper warning thresholds.
For a discrete (on/off) sensor, the sensor state is
normal.
The sensor reading or state is unavailable.
Yellow
The reading drops below the lower warning threshold or
rises above the upper warning threshold.
Red
The meaning of the red color varies depending on the
sensor type:
For a numeric sensor, this color indicates the reading
drops below the lower critical threshold or rises above
the upper critical threshold.
For a discrete (on/off) sensor, this color indicates the
sensor is in the "alarmed" state.
For a Schroff® LHX heat exchanger (if available), this
color indicates that at least one sensor implemented on
that heat exchanger fails. See Schroff LHX Heat
Exchangers (on page 192).
When a numeric sensor's reading crosses any upper or lower threshold,
the background color of the whole row turns to yellow or red for alerting
users.
For a discrete (on/off) sensor, the row changes the background color
when the sensor enters the abnormal state.
Note: Numeric sensors use numeric values to indicate the environmental
or internal conditions while discrete (on/off) sensors use alphabetical
characters only to indicate the state changes.
See the table for the meaning of each color:
Chapter 3: Getting Started
59
To find the exact meaning of the alert, read the information shown in the
State (or Status) column:
below lower critical: The numeric sensor's reading drops below the
lower critical threshold.
below lower warning: The numeric sensor's reading drops below the
lower warning threshold.
above upper critical: The numeric sensor's reading reaches or
exceeds the upper critical threshold.
above upper warning: The numeric sensor's reading reaches or
exceeds the upper warning threshold.

User and Role Management
Managing Users
The EMX is shipped with one built-in user profile: admin, which is used
for initial login and configuration. This profile has full system permissions,
and should be reserved for the system administrator. It cannot be
deleted and its permissions are not user-configurable except for the
SNMP v3 permission.
All users must have a user profile, which specifies a login name and
password, and contains additional (optional) information about the user.
Every user profile must have at least a role to determine the user's
system permissions. See Setting Up Roles (on page 69). To manage
any settings, you must log in to the user account with appropriate
permissions.
By default, multiple users can log in simultaneously using the same login
name.

Note: The EMX supports a maximum of 3 DNS servers. If two IPv4 DNS
servers and two IPv6 DNS servers are available, the EMX only uses the
primary IPv4 and IPv6 DNS servers.
Role of a DNS Server
As Internet communications are carried out on the basis of IP addresses,
appropriate DNS server settings are required for mapping domain names
(host names) to corresponding IP addresses, or the EMX may fail to
connect to the given host.
Therefore, DNS server settings are important for LDAP authentication.
With appropriate DNS settings, the EMX can resolve the LDAP server's
name to an IP address for establishing a connection. If the SSL
encryption is enabled, the DNS server settings become critical since only
fully qualified domain name can be used for specifying the LDAP server.
For information on LDAP authentication, see Setting Up LDAP
Authentication (on page 123).
Modifying the Network Service Settings
The EMX supports these network communication services: HTTPS,
HTTP, Telnet and SSH.
HTTPS and HTTP enable the access to the web interface, and Telnet
and SSH enable the access to the command line interface (see "Using
the Command Line Interface" on page 212).
By default, SSH is enabled, Telnet is disabled, and all TCP ports for
supported services are set to standard ports. You can change default
settings if necessary.
Note: Telnet access is disabled by default because it communicates
openly and is thus insecure.
In addition, the EMX also supports the SNMP protocol.
Changing the HTTP(S) Settings
HTTPS uses Secure Sockets Layer (SSL) technology to encrypt all traffic
to and from the EMX device so it is a more secure protocol than HTTP.
By default, any access to the EMX device via HTTP is automatically
redirected to HTTPS. See Forcing HTTPS Encryption (on page 104).
To change the HTTP or HTTPS port settings:
1. Choose Device Settings > Network Services > HTTP. The HTTP
Settings dialog appears.
Chapter 5: EMX Device Management
85
2. To use a different port for HTTP or HTTPS, type a new port number
in the corresponding field. Valid range is 1 to 65535.
Warning: Different network services cannot share the same TCP
port.
3. Click OK to save the changes.
Configuring the SNMP Settings, Traps and Informs
SNMP communications allow you to retrieve the status of the EMX
device. Additionally, you may need to configure the SNMP destination(s)
if the built-in "System SNMP Notification Rule" is enabled and the trap
destination has not been set yet. See Event Rules and Actions (on
page 131).
You can enable or disable SNMP communication between an SNMP
manager and the EMX device. By default, SNMP v1/v2c is enabled on
the EMX so the EMX can communicate with an SNMP manager.
The EMX provides you with the ability to create SNMPv2c and SNMPv3
TRAP communications, or SNMPv2c and SNMPv3 INFORM
communications.
SNMP TRAP communications capture and send information via SNMP,
but no confirmation that the communication between the devices has
succeeded is provided to the receiving device.
SNMP INFORM communications capture and send information via
SNMP, and an acknowledgment that the communication was received by
the receiving device is provided. If the inform communication fails, it is
resent. You can define the number of times and the intervals to resend
the inform communication, or leave the defaults of five (5) resends in
three (3) second intervals.
Note: SNMP INFORM communications may take up slightly more
network resources than SNMP TRAP communications since there are
additional communications between the devices, and due to additional
network traffic created should the initial communication fail and another
is sent.
Use SNMP TRAP rules if you do not need confirmation that the
communication has succeeded, and if you need to conserve network
resources. Use SNMP INFORM communications to ensure more reliable
communications, and if network resources can be managed with the
potential additional network traffic.
To configure the SNMP communication:
1. Choose Device Settings > Network Services > SNMP. The SNMP
Settings dialog appears.
2. Enter the destination information that applies to the trap types you
are using.
Chapter 5: EMX Device Management

Type the read/write community string in the Write Community
String field. Usually the string is "private."
4. Select the "enable" checkbox in the "SNMP v3" field to enable
communication with an SNMP manager using SNMP v3 protocol.
Tip: You can permit or disallow a user to access the EMX via the
SNMP v3 protocol. See Configuring Users for Encrypted SNMP
v3 (on page 208).
