Note: The 7GR4270-12, 7GR4202-30, 7GR4280-19, and 7KR4290-02 DFE modules can be
installed in a Matrix E7, N7, N5, N3 or N1 chassis, but only support FTM2 data backplane
interconnections in the Matrix E7 chassis. Traffic flow from FTM2 to FTM1 can only be
accomplished using a bridging module such as the 7H4382-25, 7H4382-49, 7H4383-49, or
7H4385-49.
