A Core That Fits Your Rack
Not every campus has space or thermal budget for a full-height chassis. This 4U platform brings modular switching to environments where rack depth, vertical space, or cooling capacity ruled out larger alternatives. Three business slots and dual main control deliver 166.4 Tbps ceiling in a package that slots into standard 19-inch racks without special mounting.
Grow Capacity, Not Footprint
Start with the line cards your current traffic demands and add capacity as the campus grows. Each slot accepts high-density 10G cards with non-blocking throughput across all ports. When more bandwidth is needed, additional line cards install without chassis replacement - investment protection built into the architecture.
Resilience Without the Rack Units
all modules support hot-swap with service auto-recovery - impressive for a 4U form factor. Dual main control automatic failover, N+M power redundancy, and ISSU firmware upgrades maintain service continuity during both planned and unplanned events. The same reliability stack found in 9U and 12U platforms, without the vertical cost.
Integration
Full L2/L3 including OSPF and BGP, MPLS LDP for metro handoff, and comprehensive IPv6 routing. VSS virtualization unifies multiple chassis into one logical device - reducing management overhead for campus cores that span multiple wiring closets or buildings.
Who Deploys This
Campus network architects with 3-5 building deployments, branch office aggregation points, and education IT teams upgrading from fixed-port cores to modular platforms. The 4U height and empty weight of 10.5 kg make it practical for two-person installation in standard IDF closets.
Product Features
3-Slot Modular Architecture
Three business slots in a 4U chassis provide the modularity of chassis-based switching where rack height is constrained. Each slot takes high-density 10G line cards. Dual main control slots in the same 4U form factor deliver automatic failover protection for the control plane.
01
Up to 166.4 Tbps in a Single 4U Enclosure
The distributed backplane scales from 38.4 Tbps to 166.4 Tbps as line cards are added. Forwarding performance reaches 36000 Mpps - enough to keep every 10G port at line rate under any traffic load. Capacity grows with the campus, not ahead of it.
02
Carrier-Grade Redundancy at Campus Scale
Dual main control failover, power supplies in N+M backup configuration, redundant fans, and ISSU. Every major subsystem has a backup. HW-based fault detection isolates failures deterministically. Multiple layers of protection without the complexity of full carrier platforms.
03
VSS Fabric Virtualization
Multiple chassis consolidate into a single managed entity through VSS. Cross-chassis link aggregation distributes traffic for both throughput and resilience. One management interface replaces the complexity of per-chassis configuration.
04
MPLS and Full IPv6 Routing
MPLS LDP for metro integration. Full IPv6 with OSPFv3 and BGP4+. IGMP/PIM multicast with cross-VLAN replication. The protocol coverage eliminates external routers at the campus core.

Product Advantages
Fits Where Full-Height Chassis Cannot
4U form factor and 10.5 kg empty weight install in standard two-post and four-post racks without reinforced mounting, in IDF closets where 9U and 12U chassis simply do not fit. Core switching reaches locations that previously settled for fixed-port compromises.
Modular Scalability Without Platform Replacement
Three slots grow from 38.4 to 166.4 Tbps. Add line cards as traffic demands increase - the chassis stays. This extends platform life across multiple budget cycles and avoids the disruption of core hardware swaps.
Dual Main Control in a Compact Chassis
Control plane redundancy - typically found only in large chassis - in a 4U form factor. If the active main control fails, the standby takes over automatically. Every component can be replaced while the system stays online.
Custom branding and configuration at competitive MOQ supports distributors building campus switching portfolios.
Application Scenarios
Mid-Sized Campus Core
Serves as the single-chassis core for 3-5 building campuses. 3 slots provide sufficient line card diversity for access aggregation, distribution, and data center interconnect without the over-investment of larger chassis. 4U height keeps the core in standard IDF closets, not dedicated equipment rooms.
Branch Office Aggregation
Aggregates multiple branch switches with 10G uplinks while providing MPLS handoff to the carrier backbone. Compact form factor deploys in branch equipment rooms where space is shared with servers and UPS.
Education District Office
Connects multiple school sites across a district with modular line card flexibility. Hot-swap maintenance and ISSU keep the network running during school hours. 4U chassis fits standard education IT racks without modification.
