The bezel has a deep envelope specifically designed for the IBM BladeCenter T chassis which maintains integrity of cabling when deployed with a PEU II Expansion unit. This bezel keeps cabling inside the envelope of the chassis versus having to remove the bezel to support I/O cabling. With this option, customers do not have to remove the bezel when supporting I/O applications with cabling protruding from the front of the IBM BladeCenter T chassis.
