CHAS-BP3-MX480-S Juniper MX480 BP3 Chassis
Juniper CHAS-BP3-MX480-S MX480 BP3 Chassis
Mid-Range Enhanced Backplane Chassis for Scalable MX480 Routing
The Juniper CHAS-BP3-MX480-S MX480 BP3 chassis is a next-generation 3D Universal Edge Router platform engineered to deliver high-performance, scalability, and reliability for modern service provider and enterprise networks. Designed with the advanced Backplane 3 (BP3) architecture, this chassis supports the demanding power and signal integrity requirements of high-speed 100GbE and 400GbE networking, making it ideal for evolving data center and edge environments.
With a compact 8RU form factor, the MX480 BP3 chassis offers an optimal balance between performance and space efficiency. It features 6 total slots, including 4 dedicated MPC (Modular Port Concentrator) slots for high-capacity line cards and 2 SCB (Switch Control Board) slots for switching and control plane operations. When paired with compatible SCB3 and MPC line cards (MPC7E, MPC10E, MPC11E), the system delivers an impressive aggregate throughput of up to 7.5 Tbps, enabling seamless handling of high-bandwidth workloads.
The BP3 backplane technology enhances system performance by supporting higher per-slot power and enabling high-frequency signaling required for multi-rate interfaces such as 10GbE, 40GbE, 100GbE, and 400GbE. This ensures future-ready scalability while maintaining backward compatibility with existing MX-series MPCs.
Built for carrier-grade reliability, the Juniper MX480 chassis incorporates redundant switch control boards, routing engines, power supplies, and fan trays, ensuring continuous operation and minimal downtime. Its side-to-side airflow cooling design supports efficient thermal management in high-density rack environments, while N+1 power redundancy ensures consistent and reliable power delivery for mission-critical applications.
Ideal for service provider edge deployments, mobile backhaul, enterprise core networks, and cloud infrastructure, the Juniper CHAS-BP3-MX480-S delivers the performance, scalability, and resilience required for next-generation networking environments.

FAQs:
Q1. Why is the BP3 chassis required for newer MPCs?
Newer line cards like the MPC10E require more power and faster data paths than the original MX480 backplane could provide. The BP3 chassis upgrades the electrical and signal infrastructure to meet these modern requirements.
Q2. How many 100GbE ports can I fit in this chassis?
Depending on the line cards used (such as the MPC7E-MRATE), you can achieve high-density 100GbE configurations across the four available line card slots, supporting up to 48 ports of 100GbE.
Q3. Does this part number include the fan trays?
Typically, the "CHAS-BP3-MX480-S" is a spare chassis that includes the frame and backplane. High-capacity fan trays and power supplies are usually ordered as separate components or part of a system bundle.
Q4. Can I use my existing RE-S-1800X4-16G in this chassis?
Yes. The BP3 chassis is compatible with standard MX-series Routing Engines, provided they are paired with compatible Switch Control Boards (SCBE2 or SCBE3).
Q5. Is the airflow front-to-back?
No. The MX480 uses a side-to-side airflow pattern. You must ensure proper clearance on the sides of the rack for intake and exhaust.
