IBM 1754 LCM8 and LCM16 Local Console Managers 3
With server densities continually increasing, cable bulk remains a major concern for network
administrators. The LCM8 and LCM16 switches significantly reduce KVM cable volume in the rack by
utilizing the innovative conversion option cables and single, industry-standard CAT-5 UTP cabling. This
allows a higher server density while providing greater airflow and cooling capacity. In addition, multiple
target systems can be daisy-chained together using CAT-5 cables, and then all connected to the console
switch using one cable, thereby eliminating a lot of cable clutter.
The IBM 1754 LCM Digital Activation Key, part number 81Y2393, is a software upgrade that turns your
IBM 1754 Local Console Manager KVM analog switch into a digital device enabling remote access to
servers it is connected to. No hardware changes are needed.

* The 1x8 and 2x16 console switches support the use of the Virtual Media Conversion Option (VCO) for
connectivity, but they do not support the use of remote virtual media. The use of the VCO with these console
switches represents a lower-cost alternative to the UCO if chaining is not required.
