Installation Environment
The duct work shown in the following diagram is not used for mounting the
Racks. Although optional, the duct work can be used to house the wires from
the I/O Units that run along the sides of the Racks, keeping the wires from
becoming entangled with other machines. The figures illustrate the correct
way to mount the Racks.
The following figure shows a side view of a mounted CPU and two Expansion
I/O Racks. There should be a distance of 70 to 120 mm between the
mounted Units.
