The autorun script in the root of the resource media detects when there is no graphical environment 
running and automatically starts the installer in a text-based mode. This mode provides the same options 
as graphical installation with the exception of the MDCU specific options. The MDCU requires a graphical 
environment to operate.
NOTE: The console mode installer provides the option to install the MDCU. However, a graphical 
environment is required to utilize the MDCU.
Silent Installation
Silent Installation On Windows Systems
To run silent installation on a Windows system:
1. Copy the custom_silent.properties file in the /windows folder of the installation media or image to a 
writable location on the host server.
2. Modify the custom_silent.properties file to reflect the features, models, and installation options to 
be used. Then, save the file.
3. Once the custom_silent.properties file is revised to reflect your specific installation, run the 
following command to begin the silent installation: mdss_install.exe –f <host_server_path>\ 
custom_silent.properties.
Silent Installation On Linux Systems
NOTE: On Red Hat Enterprise Linux 6 operating systems, run the following script from the root 
directory to install prerequisite packages: 
# md_prereq_install.sh.
1. Copy the custom_silent.properties file in the /linux folder of the installation media or image to a 
writable location on the host server.
2. Modify the custom_silent.properties file to reflect the features, models, and installation options to 
be used. Then, save the file.
3. Once the custom_silent.properties file is revised to reflect your specific installation, run the 
following command to begin the silent installation:mdss_install.bin –f <host_server_path>/ 
custom_silent.properties.
