The IBM BladeCenter Optical Pass-thru Module provides non-switching, non-blocking connections between blade server expansion cards and external switches. Pass-thru modules are not switches, but insert into BladeCenter switch bays. The Optical Pass-thru Module provides fiber optic connectivity to each blade server in a BladeCenter, without providing any internal switching capability. The OPM provides an unconfigured gigabit network connection to connect blade servers to an existing network infrastructure.
See the Installation Guide for the IBM BladeCenter Optical Pass-thru module.
