About the Juniper SCB-MX960-S-A Switch Control Board for MX960 Router
The Juniper SCB-MX960-S-A Switch Control Board delivers active-passive and active-active high-availability configurations through support for Graceful Routing Engine Switchover (GRES) and Non-Stop Routing (NSR) when paired SCB modules are installed, ensuring continuous packet forwarding during failover events. This field-replaceable unit (FRU) is purpose-built for the Juniper MX960 Universal Routing Platform and features enhanced switching fabric required for full-capacity line cards such as the MPC5E, MPC6E, and MPC7E series. The part number SCB-MX960-S-A identifies this AC-powered variant with hot-insertable/extractable capability—enabling online insertion and removal without service interruption.
Network engineers deploying carrier-class routing infrastructure will find the SCB-MX960-S-A essential for maximizing MX960 throughput and availability. The MX960 chassis accommodates 3 SCB slots (SCB0, SCB1, SCB2), and Juniper recommends populating all 3 slots to achieve full fabric redundancy. Each SCB includes an integrated Routing Engine bay that accepts compatible modules such as the RE-S-X6-64G, while the AC power input ensures compatibility with standard enterprise power distribution. The unit connects via MX960 midplane fabric connector and runs Juniper JUNOS across all supported releases for MX960 enhanced fabric environments. Manufacturer support is included with every unit, and hot-swap operation allows maintenance without downtime.
Deployment Scenarios
- Carrier and service provider core routing deployments requiring three-slot redundant switching fabric across all SCB0, SCB1, and SCB2 positions
- Multi-protocol environments where MPC5E, MPC6E, or MPC7E line cards demand enhanced switching fabric performance
- Mission-critical networks leveraging GRES and NSR to achieve non-stop routing during planned maintenance or unscheduled failover
- Data center interconnect and backbone routing where hot-swap capability minimizes operational risk
- High-throughput environments where active-active or active-passive HA configurations protect against single points of failure
