3 Product description
EN 3 Product description
3.1 Functional description and components
3.1.1 Function
The Access Control serves to monitor rack doors via
an infrared access sensor. In addition to this, a CMC
III reader unit and a handle can be connected to the
interfaces. The access sensor reports to the CMC III
Processing Unit (base systems) whether the door is
open or closed. Codes for the door release are input
on the coded lock. The door can then be opened and
monitored with an electromagnetic handle. The Access
Control has an identification that allows it to be detect-
ed automatically by the CMC III Processing Unit (base
systems).
Note:
In the following text, the designation
"CMCIII Processing Unit" refers to the
"CMC III Processing Unit" variants and also
to the base systems. All text passages that
apply only to a specific variant are identified
accordingly.
3.1.2 Components
The device consists of a compact plastic housing in
RAL7035 with a ventilated front in RAL 9005.
3.2 Proper use, foreseeable misuse
The CMCIIIAccess Control serves exclusively to mon-
itor access to a server enclosure. It may only be used
together with the CMCIIIProcessing Unit. Any other
use is not permitted.
The unit is state of the art and built according to rec-
ognised safety regulations. Nevertheless, incorrect use
may result in damage to or faults with the system and
other material assets.
Consequently, the unit must only be used properly

EN 5 Installation
5.1 Safety instructions
◾ Please observe the valid regulations for installation
in the country in which the Access Control is in-
stalled and operated, and the national regulations for
accident prevention. Please also observe any internal
company regulations, such as work, operating and
safety regulations.
◾ The technical specifications and limit values stated
must not be exceeded under any circumstances. In
particular, this applies to the specified ambient tem-
perature range and IP degree of protection.
◾ If a higher IP protection class is required for a special
application, the Access Control must be installed in
an appropriate housing or in an appropriate enclo-
sure with the required IP degree of protection. Under
certain circumstances, the integral infrared sensor
may then no longer function.
5.2 Siting location requirements
To ensure the unit functions correctly, the conditions
for the installation site of the unit specified in section 8
"Technical specifications" must be observed.
Electromagnetic interference
– Interfering electrical installations (high frequency)
should be avoided.
5.3 Installation procedure
There are generally several options for installing the
Access Control:
1. Installation on the frame of the enclosure or IT
enclosure using the bracket included.
2. Installation with the provided bracket on a system
chassis.
3. Installation on a top-hat rail using the bracket in-
cluded along with a spring clip.
5.3.1 Installation notes
◾ Install the Access Control in such a way that the front
with the transmitter and receiver points toward the
door to be monitored.
◾ Preferably, install the Access Control in such a way
that the infrared access sensor points toward the
lock-side and not the hinge-side of the door to be
monitored.
◾ Because the angle of the reflecting foil changes fast-
er, an opened door will be detected faster.

sponding line is added at the end of the ta-
ble as in the case where a new transponder
card is added.
6.5.2 Four-eyes principle
When the four-eyes principle is activated, two persons
must identify themselves to open a handle or a door. To
do this, two dierent persons must register themselves
with their transponder cards or their number code with-
in a set time interval on the same card reader.
To activate the four-eyes principle:
◾ Assign the "AccessAck" user to a transponder card
or a number code in the "Access Configurations"
dialogue.
By default, this user is present on each CMCIII Pro-
cessing Unit and belongs to the "Access" group to
which no further rights are assigned.
◾ If the "AccessAck" user and/or the "Access" group
are not present (e.g. because prior to an update of
the CMCIII Processing Unit, all storage spaces are
already occupied), you must manually create the user
and the group (refer to the CMC III Processing Unit
assembly and operating instructions).
◾ Set the time interval in the "Confirm Timeout" field
within which the two users must register for activated
four-eyes principle.
After saving this assignment, the four-eyes principle
governs the complete access control. Consequently,
at least two transponder cards or two access codes
are required for each reader unit.
Note:
After activation of the four-eyes principle,
each reader unit should also be assigned
a transponder card or a number code with
the "AccessAck" user. This user is always
required so that a closed handle or door
can be opened.
To open a handle or a door:
◾ The first user registers himself/herself with his/her
transponder code or number code on the reader unit.
◾ The second user registers himself/herself with his/her
transponder code or number code within the set time
interval on the same reader unit.
At least one of the two users must be the "AccessAck"
user. The order with which the users register does not
matter.

14 Rittal CMC III Access Control
6 Operation
EN Note:
The time interval within which the two users
must register can also be specified directly
in the "access.cmc3" file (see section 6.7
"Manual changes to the “access.cmc3”
file").
6.5.3 Assignment of reader units to access
modules
By default, on input of an authorised code or holding
an authorised card at a reader unit, all handles and
virtual access controllers assigned to the associated
access authorisation in the Access group frame are
opened or switched, respectively (see section 6.5.1
"Specification of the access authorisations").
Reader units and access modules can now be as-
signed to each other in the Keypad Mapping group
frame. This allows you to control which handles and
doors can be opened depending on the associated
reader unit.
– No assignment stored: All access modules as-
signed to the associated access authorisation in the
Access group frame are authorised.
– Assignment between the reader unit and the
access module(s) stored: Only those access
modules assigned to the associated reader unit are
authorised. These access modules must also be
assigned in the Access group frame as a device to
the associated access authorisation.
To configure the assignment of a reader unit to
specific handles and doors:
◾ Mark in the Keypad Mapping group frame the line
with the access module to which the reader unit is
connected, and to which you want to assign specific
handles and doors.
◾ Click the Edit button.
The "Access Configuration" dialogue opens.
Parameter Explanation
Use Enable or disable individual access
modules for the previously selected reader
unit.

be opened, irrespective of which reader unit
is used.
6.6 Monitoring tab
All settings for the Access Control, such as the sen-
sitivity of the integrated access sensor, are made on
the Monitoring tab. You have a choice between two
display options:
– Tree display: This allows fast, targeted access to
individual parameters.

6.7 Manual changes to the "access.cmc3"
file
Alternatively, the access authorisation settings can also
be made directly in the "access.cmc3" file. This file is
created automatically in the "upload" directory of the
CMCIII Processing Unit when it is started for the first
time.

Rittal CMC III Access Control 17
6 Operation
EN
Note:
If the "access.cmc3" file is removed from
the folder, access is only then possible
using the three predefined access codes
"1001", "1002" and "1003". All other access
authorisations have to initially be added
again to a newly created file.
6.7.1 Downloading the file
Note:
The following descriptions assume that you
establish an (S)FTP connection using the
"FileZilla" program. If another program is
used, the file may have to be downloaded
and uploaded in a dierent way.
◾ First establish an FTP or SFTP connection to the
CMCIII Processing Unit from a PC (see the assembly
and operating instructions for the CMCIII Processing
Unit).
◾ In the left-hand subwindow (PC), switch to the folder
where you wish to locally save the "access.cmc3"
file.
◾ Switch to the "upload" folder in the right-hand sub-
window (CMCIII PU).
◾ Right-click the "access.cmc3" file and select the
"Download" action.
◾ Disconnect the (S)FTP connection between the PC
and CMCIII PU.
If there is no "access.cmc3" file in the "upload" directo-
ry, this has to be created first.
◾ When using a coded lock: Input any sequence of
numbers on the coded lock and confirm using the
"Enter" key. The file is now generated in the "upload"
folder.
◾ When using a transponder reader: Hold any tran-
sponder card in front of the reader unit. The file is
now generated in the "upload" folder.
◾ Establish an (S)FTP connection between the PC and
CMCIII PU again and download the file.
◾ Disconnect the (S)FTP connection between the PC
and CMCIII PU again.
6.7.2 Editing the file
The file can now be edited using a text editor. Rittal
recommends using "Notepad++" for this instead of the
standard "Notepad" editor installed under Windows.
This is available online as freeware.
Fig.16: "access.cmc3" file in Notepad++
The file is structured as follows:
– Lines starting with a "#" are comment lines. These
contain basic information on the CMCIII Processing
Unit.
– Lines with "Key" or "Crd" as first entry contain the
authorised access codes if a numeric coded lock is
used, or the authorised card numbers of the tran-
sponder cards if a transponder reader is used (see
section 6.5.1 "Specification of the access authorisa-
tions").
– The line with "4-Eyes" as first entry contains the time
interval for the registration in the four-eyes principle
(see section 6.5.2 "Four-eyes principle").
– Lines with "Keypad" as first entry contain the assign-
ment of reader units to individual access modules
(see section 6.5.3 "Assignment of reader units to
access modules").
Access codes and transponder cards
The lines for the access codes and the transponder
cards contain the following entries:
Parameter Explanation
Key Access code containing up to eight digits
for a coded lock for authorised access.
Crd Card number of a transponder card for
authorised access.
User User to be entered in the CMCIII Pro-
cessing Unit logfile when the coded lock
is opened with the associated access
code or on opening with the associated
transponder card. This user has to exist in
the CMCIII PU.
Information Specific additional information for the ac-
cess. This text is also added for the user
in the CMCIIIProcessing Unit logfile.
Handle Serial number of the Access Control or
(virtual) access controller to which the
access module to be switched is connect-
ed. Several comma-separated entries for
dierent Access Control units can also be
added here.

(line 12). User "Rittal" and the information "Info 2" are
entered in the CMCIII PU logfile.
– Both handles are opened using access code
"12345678" (line 13). User "admin" and the informa-
tion "Info 3" are entered in the CMCIII PU logfile.
In lines 15 to 17, a transponder card has also been as-
signed to each of the users. These transponder cards
open the same handles as the access codes above.
The respective users and associated information are
entered in the CMCIII PU logfile.
Time interval for the four-eyes principle
The time interval for registration in the four-eyes princi-
ple is specified in the line with the "4-Eyes" entry.
