As far as I know, MX960 Supports two types of Midplane(Normal and Enhanced)
I wonder is there any compatibility note between Enhanced Midplane a cards, SCBE and RE?
Specially between MPC7E variants and Enhanced midplane?
MPC7 supported on SCBE2 (MX-SCB & MX-SCBE are not supported.), hence you should use the matching REs (RE-S-X6-64G , RE-S-X6-128G , RE-S-1300 , RE-S-2000 ,RE-S-1800 , RE-S-2000-4096) with SCBE2.
MPC7 requires High capacity PEMS for fully loaded chassis. (e.g., 11 /12 line cards in an mx960)
You can use SCBE2 with the normal Midplane however we do recommend using Enhanced Midplane to be able to run the fabric links faster.
