I am yet another that uses and loves Cyclades in my data center. The new ACS
6000 series is what I have now, which is quite nice due to the software pin
switching they have on that unit, this means no more special cisco dongles.
Also part of the reason for my use of the ACS is for the integration of the
Cyclades power strips, very seemless very nice. I have also used the Cisco
terminal server mods in the past and they worked just fine as well, though I
have no modern experience there.
