The Intelligent Copper Pass-thru Module (ICPM) for IBM BladeCenter (44W4483) is a low-cost solution, ideal for clients who want to use their existing switching infrastructure with IBM BladeCenter. It does not require any configuration and so is very easy to use.Pass-thru modules are I/O options that can be used for direct connections of blade ports to the external infrastructure devices such as network switches. The Pass-thru module is almost like a traditional network patch-panel - it routes internal blade ports to outside the BladeCenter.
