Using the ITSL expansion module, a connection is established to an
extremely fast, synchronous
SIMOLINK fiber-optic cable bus
The expansion module is inserted on a CPU module (PM5, PM6). A
maximum of 2 ITxx expansion modules can be inserted on a CPU module.
An ITxx occupies 1 slot (in addition to the CPU module slot).
• 2 plug connectors for an incoming and outgoing fiber-optic cable
Fiber-optic cable
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
elements using the M4 nuts provided (and washers).
If a second ITxx module is used, the first ITxx must be screwed using
plastic distance pieces (this is 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.
• operation without fan is possible
• noise-immune operation is only possible if the module is tightly screwed
into the subrack
