Introduction to Regular Asset Strips
Each tag port on the regular asset strips corresponds to a
rack unit and can be used to locate IT devices in a specific
rack (or cabinet).
For each rack, you can attach asset strips up to 64U long,
consisting of one MASTER and multiple SLAVE asset strips.
The difference between the master and slave asset strips is
that the master asset strip has an RJ-45 connector while the
slave does not.

EMX Quick Setup Guide 3
QSG-EMX-1A-v3.3.10-E 255-80-6106-00 RoHS
The following diagram illustrates some asset strips. Note that
Raritan provides more types of asset strips than the diagram.
8U MASTER asset strip with 8 tag ports
8U SLAVE asset strip with 8 tag ports
5U "ending" SLAVE asset strip with 5 tag ports
Note: Unlike general slave asset strips, which have one DIN
connector respectively on either end, the ending slave asset
strip has one DIN connector on only one end. An ending asset
strip is installed at the end of the asset strip assembly.
QSRu le
Introduction to Asset Tags
You need both asset strips and asset tags for tracking IT
devices.
Asset tags provide an ID number for each IT device. The asset
tags are adhered to an IT device at one end and plugged in to
an asset strip at the other.
The asset strip is connected to the EMX, and the asset tag
transmits the ID and positioning information to the asset strip.
The following diagram illustrates an asset tag. Note that there
are two types of asset tags: non-programmable and
programmable tags. The only difference is that
programmable asset tags allow you to customize each tag's
ID or barcode number while non-programmable ones have
factory default ID or barcode numbers, which you cannot
change.
A Barcode (ID number), which is available on either
end of the "non-programmable" asset tag
B Tag connector
C Adhesive area with the tape
Note: The barcode of each "non-programmable" asset tag is
unique and is displayed in the EMX device's web interface for
identification.
QSRu le
Assembling Regular Asset Strips
Before connecting regular asset strips to the EMX, you must
assemble them.
To assemble regular asset strips:
1. Connect all regular asset strips up to 64U. For detailed
information, see the user documentation accompanying
Raritan asset strips.
a. The MASTER asset strip is installed as the first one in
the asset strip assembly.
b. All SLAVE asset strips are connected following the
MASTER asset strip.
c. The "ending" slave asset strip is installed as the final
one.
2. Vertically attach the asset strip assembly to the rack, next
to the IT equipment, making each tag port horizontally
align with a rack unit.
The asset strips are automatically attracted to the rack
because of magnetic stripes on the back.
QSRu le
Connecting Regular Asset Strips to EMX
The EMX supports a cabling distance up to 10 meters for each
connected asset strip assembly.
For EMX2-111, a Raritan X cable is required for connecting
asset strips, or the EMX2-111 CANNOT detect them.

EMX Quick Setup Guide 4

Other Types of Asset Strips
Raritan provides more types of asset strips than regular asset
strips, such as composite asset strips or blade extension
strips. For detailed information, see the user documentation
accompanying Raritan asset strips.
Composite asset strips:
A composite asset strip is named AMS-Mx-Z, where x is a
number, such as AMS-M2-Z or AMS-M3-Z.
A composite asset strip has two RJ-45 connectors but less
tag ports.
The composite asset strip is especially useful for tracking
large devices such as SAN boxes in the cabinet.

QSG-EMX-1A-v3.3.10-E 255-80-6106-00 RoHS
Composite asset strips can be daisy chained as shown
below.
Blade extension strips:
For blade servers, which are contained in a single chassis,
you can use a blade extension strip to track individual
blade servers.
A blade extension strip contains 4 to 16 tag ports. Below
shows a blade extension strip with 16 tag ports.
The blade extension strip is connected to a tag port on a
regular or composite asset strip via a Raritan's tag
connector cable.

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 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.

Appendix C: Other Information
Installing the USB-to-Serial Driver (Optional)
The EMX can emulate a USB-to-serial converter over a USB
connection. A USB-to-serial driver named "Dominion EMX
Serial Console" is required for Microsoft®Windows®operating
systems.
Download the Windows driver for USB serial console from the
Raritan website's Support page
(
http://www.raritan.com/support/ ). The downloaded driver's
name is dominion-serial-setup-<n>.exe , where <n>
represents the file's version number.
There are two ways to install this driver: automatic and
manual installation. Automatic driver installation is highly
recommended.
Automatic driver installation in Windows®:
1. Make sure the EMX is NOT connected to the computer via
a USB cable.
2. Run dominion-serial-setup-<n>.exe on the computer and
follow online instructions to install the driver.
Note: If any Windows security warning appears, accept it
to continue the installation.
3. Connect the EMX to the computer via a USB cable. The
driver is automatically installed.
Note: Manual installation is required only if the automatic
installation fails. See the section titled "Installing the
USB-to-Serial Driver (Optional)" in the online help for manual
installation procedure.
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

EMX Quick Setup Guide 10
QSG-EMX-1A-v3.3.10-E 255-80-6106-00 RoHS
"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
