Installing operating system on Dell C5230

Hi All,

We have a used Dell C5230  with 12 blades. We got it with empty disks (nos system on them). I see on the manual that there is a console/kvm cable, what cab be used to connect monitor and keyboard and install a system on the blades (see the attached screenshot from the manual). I also found the part number (2T2N6) in Dell community forum. However, it looks like, the cable is not available (at least I did not find a source).

Is there any other way to install op. system on C5230 blades?

Thank you
