Local Console Connection The local console connector allows a direct connection to a blade server to allow operating system installation and other management tasks to be done directly rather than remotely.

  • Page 7: Modular Storage Subsystem

    Because the blade server can be used without disk drives, it does not come with any modular storage subsystems installed. Blanking panels should be used on a diskless UCS B420 M4 blade server to ensure proper airflow. Order the same number of blanking panels as there are empty drive bays.
