Scbe3-Mx Maximum Power Consumption Per Ambient Temperature And Cb Slot - Juniper MX960 Hardware Manual

Two SCBE3-MX's installed in the MX240 or MX480 are required for 1 + 1 redundancy. To provide 1 +
1 fabric redundancy, there must be an SCBE3-MX installed in slot 1.
NOTE:
If SCB 0 fails, SCB 1 will be automatically configured with four fabric planes active. In this
fail over scenario, the SCBE3-MX will support full line rate 100% redundancy.
If SCB 1 fails, SCB 0 has only two available fabric planes; therefore, in this failover mode,
the line rate will drop to 50%.
