Advanced performance and control for growing networks
HPE Networking Instant On Switch Series 1940 is designed for businesses that have outgrown basic access switching and need higher throughput, richer controls, and stronger security.
The series spans flexible 8-, 24-, and 48-port access models plus aggregation options to support a wider range of wired architectures.
Select models add HPE Smart Rate multi-gigabit ports and 10G uplinks to support newer Wi-Fi, high-throughput endpoints, and bandwidth-intensive applications.
Built-in static routing enables efficient inter-VLAN traffic handling directly at the edge to improve local performance.
Enterprise-grade security and smarter operations
HPE Networking Instant On Switch Series 1940 helps reduce risk with TPM 2.0, TACACS+, AAA authentication and accounting, ACLs, and stronger management access controls.
Direct Ops Commands, richer diagnostics, and SNMP read-only cloud access help IT teams troubleshoot and integrate operations more effectively.
Cloud, mobile, and local management options give administrators flexibility without adding license or subscription costs.
Always On PoE and Quick PoE help keep critical devices powered and reduce downtime during restarts or maintenance windows.
Purpose-built for advanced access and aggregation roles
HPE Networking Instant On Switch Series 1940 fits growing organizations that need more than a standard 1G access layer and want room to scale.
It supports advanced access deployments for healthcare, hospitality, retail, offices, and other environments with dense client and device demands.
The series can serve as dedicated edge access or hybrid access and aggregation depending on the model and deployment need.
Higher PoE capacity, multi-gigabit connectivity, and 10G uplinks make it better aligned to modern wireless, surveillance, and converged infrastructure requirements.
HPE Networking Instant On Switch Series 1940 is an advanced smart-managed Layer 2+ switch series built for growing SMB environments that need higher performance, stronger security, and greater flexibility at the edge. Available in 8-, 24-, and 48-port access models plus aggregation options, the series combines gigabit, HPE Smart Rate multi-gigabit, 10G uplinks, and static routing to support demanding voice, video, data, and AI-ready workloads. Administrators can deploy and manage the series through the Instant On Cloud Portal, mobile app, or local web GUI, while features such as Direct Ops Commands, SNMP read-only cloud access, and enhanced diagnostics simplify operations. TPM 2.0, TACACS+, AAA authentication and accounting, ACLs, and management access controls strengthen protection, while select models add Class 6 PoE, HPE Smart Rate ports up to 10G, and faster hardware performance to support modern wireless and IoT infrastructure.
