Support for SCBE2

The Enhanced SCB-SCBE2-supports the following features:

• Increased fabric bandwidth per slot
• Improved external clock redundancy
• Dynamic multicast replication only
• GRES
  During normal operation, Junos OS does not support mixing of MX-SCB, MX-SCBE, and MX-SCBE2. However, mixed SCB support is provided during the SCB upgrade process.
  The following scenarios are to be noted when you are using an MX Series router with an SCBE2:
• You must configure the set chassis network-services (enhanced-ip | enhanced-ethernet) configuration command and reboot the router to bring up the FPCs on the router. However, after the router reboots, the MS DPC, the MX FPC, and the ADPC are powered off.
• All the FPCs and DPCs in the router are powered off when you reboot the router without configuring either the enhanced-ip option or the enhanced-ethernet option at the [edit chassis network-services] hierarchy level.
• You must reboot the router when you configure or delete the enhanced-ip option or the enhanced-ethernet option at the [edit chassis network-services] hierarchy level.
