PRODUCT OVERVIEW & MARKET POSITIONING
Engineered for enterprise aggregation layers and carrier-edge deployments, the stackable gigabit switch bulk series delivers high-density Gigabit Ethernet connectivity with true physical stacking architecture. Designed to unify up to eight individual units into a single logical chassis, this platform eliminates spanning-tree complexities while providing sub-50ms link failover. The bulk SKU configuration is specifically optimized for large-scale infrastructure rollouts, data center top-of-rack deployments, and campus distribution networks requiring predictable forwarding performance and operational simplicity.

HARDWARE ARCHITECTURE & CHASSIS DESIGN
The switch employs a modular, fan-out backplane design supporting mixed fiber and copper interfaces across all 48x 10/100/1000BASE-T ports and 4x 10G SFP+ uplinks. Stacking is accomplished via dedicated 40G QSFP+ stack ports (two per unit), achieving a 160Gbps stack ring bandwidth. Internal airflow is front-to-back with N+1 redundant fan assemblies, enabling hot-swap replacement without service interruption. The bulk packaging variant streamlines procurement for projects exceeding 50 units, reducing per-unit logistics costs while maintaining identical hardware revision control.
HARDWARE FEATURES & REDUNDANCY MECHANISMS
– Physical stacking: Up to 8 units, 384 Gigabit ports + 32x 10G uplinks per stack
– Single IP management with distributed link aggregation (LACP cross-stack)
– Hot-swappable power supplies: 1+1 redundant AC (100-240V) or DC (-48V) options
– IEEE 802.3az Energy Efficient Ethernet (EEE) for idle port power reduction
– Hardware-based IPv4/IPv6 routing: 32k host table, 16k route entries
– Jumbo frame support up to 12kB
– Layer 2 feature set: 802.1Q VLAN (4k active), MSTP, IGMP snooping, GVRP
– Layer 3 base features: Static routes, RIP, OSPFv2, VRRP
COMPLIANCE & STANDARDS CERTIFICATION
This platform holds full CE, FCC Part 15 Class A, VCCI, and RCM certifications for global deployment. Safety compliance includes IEC 62368-1, UL 60950-1, and CB Scheme. Environmental adherence to RoHS2, REACH, and WEEE directives. NEBS Level 3 compliance is available for GR-63-CORE and GR-1089-CORE on DC-powered SKUs. The bulk switch array carries an MTBF of 310,000 hours (MIL-HDBK-217F, 40°C ground benign).
