S3K88A HPE 2-slot TAA 5945 Managed Switch

High-Performance 19-inch Managed L2/L3 Data Center Switch featuring 100GbE uplinks with the S3K88A

The S3K88A is an HPE Networking Comware 5945 series, rack-mount 2-slot chassis designed for top-of-rack aggregation and resilient access switching where deterministic throughput and segmentation are mandatory. With 100GbE QSFP28 uplinks, the platform aligns to leaf-spine fabrics and high-bandwidth server rows, while maintaining full L2/L3 control for multi-tenant VLAN domains and routed overlays.

Engineered as a managed, stackable Ethernet switch, S3K88A supports enterprise switching and routing features such as ECMP, BFD, MSTP, and MLD to sustain availability during link, node, or path events. Operationally, QoS, Jumbo Frames, sFlow, LLDP, and DCBX enable predictable forwarding for mixed east-west and north-south traffic patterns, while standards alignment with IEEE 802.1Q/802.1X/802.3ad supports secure access control and link aggregation at scale. The management design integrates console access via mini-USB and RJ-45, a dedicated USB Type-A service port, and both RJ-45 and SFP management LAN interfaces for flexible out-of-band workflows.

Why Choose the S3K88A?

The S3K88A provides a balanced density-to-performance ratio by combining a compact 2-slot chassis footprint with 100GbE fabric attachment for aggregation and distribution roles. It is suited to standardized rack deployments where predictable failover, scalable L2/L3 policy enforcement, and stack-based operational consistency reduce change risk across pods and availability zones.

HPE designs the Comware switching portfolio for enterprise reliability, emphasizing standards-based interoperability, robust control-plane behavior, and maintainable lifecycle operations aligned to modern data center cabling, management, and redundancy practices, including optional redundant PSU support where required.

Key Applications:

• Top-of-rack aggregation with 100GbE uplinks
• Leaf-spine edge switching for east-west traffic
• VLAN-segmented multi-tenant data center access
• Enterprise core/distribution L2/L3 routing with ECMP
• Telemetry-enabled operations with sFlow and LLDP
