SCBE2-MX Fabric Planes and Redundancy

For the MX960:
Each SCBE2-MX provides two switch fabric planes for packet forwarding among the MPCs in the MX960.
The MX960 chassis may contain up to three SCBE2-MX's Therefore, six fabric planes are available.
Three SCBE2-MX's are required for 2 + 1 redundancy.
In redundant fabric mode, four fabric planes from the first two SCBE2-MX's will be in Active mode, and
two fabric planes from the third SCBE2-MX will be in Spare mode.
In a non-redundant fabric mode, all six fabric planes will be in Active mode to increase fabric bandwidth.
For the MX240 and MX480 routers:
Each SCBE2-MX provides four switch fabric planes for packet forwarding among the MPCs in the MX480
and MX240 chassis.
The MX480 and MX240 routers contain a maximum of two SCBE2-MX's. Therefore, eight logical planes
are available.
Two SCBE2-MX's are required for 1 + 1 redundancy.
In redundant fabric mode, four fabric planes from the first SCBE2-MX will be in Active mode, and four
fabric planes from the second SCBE2-MX will be in Spare mode.
In a non-redundant fabric mode, all eight fabric planes will be in Active mode to provide increased fabric
bandwidth.
Each fabric ASIC is configured in virtual plane mode, where two virtual planes exist on one fabric ASIC.
