•
SCB-MX is the first-generation switch control board. The SCB-MX is designed to work with
first-generation DPC line cards.
•
The SCBE-MX is the second generation switch control board and is designed specifically for use with
MPC3E line cards to provide full line-rate performance and redundancy without a loss of bandwidth.
•
The SCBE2-MX provides improved fabric performance for high-capacity line cards using the third
generation fabric XF2 chip (MPC4E, MPC5E, MPC2/3 NG, and MPC7E).
•
The SCBE3-MX Enhanced Switch Control Board provides improved fabric performance and bandwidth
capabilities for high-capacity line cards using the ZF-based switch fabric.
Table 4 on page 4 compares the SCB capacities of the MX Series 5G Universal Routing Platforms.
Table 71 on page 147 lists the supported routing engines per SCB.
