5.4.5 Mounting
The Itxx module is mounted outside the subrack on a PMx CPU module or is
inserted on an Itxx module already mounted on a PMx (using the 96-pin plug
connector on the module).
All of the modules must be bolted together using the distance pieces
provided (3 are provided)!
The first ITxx, located directly on a CPU module, must be retained using the
metal distance pieces (these are included in the scope of supply of the
PMx). This establishes the electrical contact which is required to identify the
first expansion board.
The metal distance pieces are first retained on the PM4 using the M3
screws, washers and spring washers supplied.
If only one ITxx module is used, then it is screwed to the metal distance
pieces using the M4 nuts provided (and washers).
If a second ITxx module is used, the first ITxx must be screwed using
plastic distance pieces (these are included in the scope of supply of the
ITxx modules).
The second ITxx module can then be inserted and retained using the M4
nuts provided (and washers).
The complete module assembly is then inserted in the subrack.
5.4.6 Application information and noise immunity
• operation without fan is possible
• noise-immune operation is only possible if the module is tightly screwed
into the subrack
