The Y1215C is a complete rack-mounting kit for the M9018B and M9019A PXIe chassis. It includes rack flanges, handles, and attachment hardware. It suspends the chassis in a Keysight Rack using only 4U of rack space. This kit is not compatible with the Y1270A Front Panel Interfacing Kit Rack rails may be needed in a non-Keysight rack and are ordered separately. When rails are used, the chassis will require 5U of rack space.
