What's New in the EMX User Guide
Important: Raritan disables SSL 3.0 and uses TLS for releases 3.0.4,
3.0.20 and later releases due to published security vulnerabilities in
SSL 3.0. Make sure your network infrastructure, such as LDAP and
mail services, uses TLS rather than SSL 3.0.
The following sections have changed or information has been added to
the EMX User Guide based on enhancements and changes to the
equipment and/or user documentation.

Package Contents .....................................................................................3
APIPA and Link-Local Addressi
The EMX provides a rack management solution that combines the
capabilities of asset management, environmental monitoring, image
surveillance, event notifications and support for Schroff
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.
ng ............................................................4
®
heat
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 sensors (asset sensors): Each asset
sensor 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
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.
webcam connected, a simple camera and video

Chapter 1: Introduction
Product Models
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.
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 sensor 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

Chapter 1: Introduction
APIPA and Link-Local Addressing
The EMX supports Automatic Private Internet Protocol Addressing
(APIPA) as of release 3.2.0.
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: The EMX in the Port Forwarding mode does not support
APIPA. See Setting the Cascading Mode (on page 136).
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 11).
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 can be obtained.
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 Selecting the Internet Protocol (on page 114).
Ho
st name - pdu.local:
You can type https://pdu.local to access the EMX instead of typing
the link-local IP address.
