0. Introduction
The stable flow of information and production is the 'lifeline' of an enterprise.
Loss of data, failure of function and production cause extensive and in many cases life-
threatening damage. Therefore, it is the declared company objective to ensure a maximum of
safety and reliability.
RITTAL offers the support to achieve this: By means of universal competence in effective
prevention, comprehensive safety, and centralized organization, i.e. teamwork for IT safety
and reliability! This results are the optimum combination of enclosure monitoring, server
administration, and climate control components.
The solution for enclosure monitoring carries the Name RITTAL CMC-TC. This concept
includes complete physical monitoring of the enclosure, i.e. temperature, humidity, vibration,
smoke, voltage up to complete enclosure locking and access control. All these items of
information are transmitted via SNMP to a management station and can easily be
administered from this point.
The system is rounded off by its modular structure. Basic monitoring can be implemented in
next to no time. When the requirements grow, the system can easily be expanded and can
also be combined with other components of the Rittal production range.
For more comprehensive systems the CMC-TC Master is ready, acting as a central
management station. It can manage up to 10 self-contained monitoring systems via one IP
address in a network. Alarm signals and monitoring-relevant data of the monitoring systems
are centrally collected and partly documented. The data collected and prepared can then be
called over the 10/100 BaseT connection or directly over a KVM console (Keyboard-Video-
Mouse console). The RITTAL SSC console is suited to this purpose. In addition, the Master
can be connected to a KVM switch.
The significant features of the RITTAL CMC-TC Master are:
• Central administration of larger enclosure monitoring systems in interlocked networks or
stand-alone
• Ethernet network connection 10/100BaseT
• Central web server for configuration
• Local administration via KVM console (2xPS/2 and VGA connection)
• Maximum expansion:
Up to 160 temperatures can be measured or
up to 80 doors can be administered
• Total compatibility with RITTAL enclosure monitoring system CMC-TC and with the
RITTAL enclosure system
• (Room) Monitoring by WebCam

3. CMC-TC Master
3.1 Description
The RITTAL CMC-TC Master is a function block making the administration, co-ordination,
documentation, and alarm indication of the monitoring system CMC-TC more comfortable
and supporting additional functions. The configuration is consisting of an Embedded Linux
PC with integrated 10-fold hub in the 1 U 482.6 mm (19”) enclosure, to which up to 10
processing units can be connected. An integrated 10/100 BaseT interface (Ethernet
interface) allows the Master to integrate the connection into the network environment of the
company. The Master can be operated off the network using the console connections
(2xPS/2, 1xVGA). This means the Master can be accessed locally or via the network.
A visible or audible alarm can be implemented using the integrated alarm relay.
The CMC-TC Processing Units are linked up by Cat5 cabling with the CMC-TC Master
installation. The data connection into the network is made via the Embedded-Linux PC. To
guarantee the connection to the network is secure, 128-bit SSL encryption is integrated.
Access to the integrated web browser of the Master is possible through a standard browser
(Internet Explorer, Mozilla Firefox, etc.). The CMC-TC Master supports the TCP/IP, SNMP,
TELNET (TeraTerm), SSH and HTTPS protocols.
The network protocols are used for communication (password and status query, switching
commands, and alarm signals) between the CMC-TC system and the authorized users in the
network (network, internet and intranet).
See Appendix C Functional diagram
The Rittal CMC-TC Master is platform-independent as long as the platform has a network
connection and a web browser available. The SNMP functionality is also platform-
independent and must support the SNMP V1.0 network management protocol. In addition,
the CMC-TC Master supports the Standard-MIB II. The private MIB is part of the scope of
supply; see CD Rom (CMC-TC-Master.MIB).

8
3.2 Design
The Master is delivered in a 482.6 mm (19”) aluminum enclosure. The Master is based on an
embedded Linux PC with integrated 10-fold hub. For future further development of the
Master, several interfaces such as PCMCIA, serial, infrared and sound interfaces are
preconfigured.
At the front the various status conditions like alarm status, network connection, and
connected monitoring systems are shown by 13 LEDs. The functions are described in detail
in Appendix G 1 Display and operating elements enclosure.
The IEC mains connection is located on the rear side of the Master. The power pack is
integrated into the Master enclosure. The IEC connection cable is available in various country
versions and must be chosen according to the country-specific specifications (see Appendix
A1 Scope of supply/Accessories – Master).
A connection point is available to ground the enclosure of the Master.
All important operating parameters (e.g. application limit, temperature and humidity, etc.) are
described in more detail in Appendix B Technical data –Master.

4. Assembly
The Rittal CMC-TC Master is mounted in the 482.6 mm (19”) level of a 482.6 mm (19”) rack.
Attention must be paid to maintaining the allowed ambient temperature and humidity ranges,
as well as the IP protection category as required for the specific application. The appropriate
information is given in Appendix B Technical data. Compliance with a higher required IP
protection category can be achieved by installation in an enclosure or enclosure system
having the required protection category.
In addition, the following points must be observed:
 When using accessories in connection with the RITTAL CMC-TC, the installation and
operating instructions for the accessories and for the RITTAL CMC-TC must be observed.
 Repair work on the RITTAL CMC-TC may be carried out only by authorized specialist.
 The number of RITTAL CMC-TC Masters in the network is optional, assuming that there
are sufficient free IP addresses available.
 In case of modification at or inside the enclosure, e.g. installation of a new CMC-TC
monitoring component, it is a must to observe the operating instructions of the enclosure.
4.1 Mechanical components
Note: The RITTAL CMC-TC Master can be mounted optionally in the front or the rear
482.6 mm (19") level.
See Appendix D Installation instructions
4.2 Electrical components
Note: During installation the existing national regulations of the country, in which the RITTAL
CMC-TC Master is to be installed and operated, must be observed.
In addition the following points must be observed:
• Existing safety devices must not be put out of action.
• The RITTAL CMC-TC may be operated only with PE conductor connection. The PE
conductor connection is made by plugging in the IEC connection cable. The requirement
for this is that the IEC connection cable is connected on the mains-side with the PE
conductor. The enclosure grounding point must be connected to the potential equalization
of the enclosure system to prevent electric shock due to residual hazardous voltages
following a malfunction.
• The electric supply voltage and frequency must correspond to the rated values given on
the rear side of the device and in Appendix B 1 Technical Data.

11
• Prior to working on the RITTAL CMC-TC this must be made voltage-free and secured
against reclosing. Furthermore, the absence of electrical power must be checked.
• Cable clamping and protection is made by means of commercial cable ties at the casing
or enclosure used.
See Appendix E 1 Electrical connection: CMC-TC master
5. Start-up
Note: The RITTAL CMC-TC is an independent system without mains switch and
automatically loads the firmware (operating system) into the main memory when the mains
voltage is connected.
Please follow the steps set out in Appendix F 1 Check list Commencing operation.
See Appendix F 1 Check list Commencing operation of CMC-TC Master
See Appendix E 2 Configuration of serial interface RS 232

The enclosure earthing is to be connected to the
potential equalization of the enclosure system. For this
purpose an earthing pin is provided at the rear side of
the enclosure. The earthing conductor is not part of the
scope of supply. The power supply of the Master is
made by a country-specific IEC cable, as named in
Appendix A1 Scope of supply/Accessories. The
integrated power pack is to be used exclusively for the
voltage supply of the CMC-TC Master!
When on voltage, the Master automatically starts the
boot
procedure.
Note: The alarm relay enters the
release condition as soon as the
master is on mains voltage. In case of
mains failure the alarm relay drops out
once, triggering an alarm. Using this
function it is possible to
implement an
on-
wire message, e.g. to a central
station.
The connection cable of the RITTAL WebCam is plugged in directly in a vacant USB port of the RITTAL CMC-
TC Master. Up to 2 Rittal WebCams are supported.
Maximum admissible cable length: 5 m.
Note:
The master unit can be set by the definition of alarm
actions so that the alarm relay is actuated with arbitrary
sensor states set by the user. The alarm relay remains
actuated as long as such a state exists.
With the actuation of the alarm relay the alarm LED on the
front of the master unit is switched to red.
The alarm relay is connected through the RJ 12 sockets
using
RJ 12 connectors. The technical specification of the
alarm relay is shown in Appendix B1 Technical data,
which
you must not exceed for technical and safety-
relevant
reasons. The assignment of the alarm relay is made by
software parameterization, see Append

relay is shown below.
