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.

What is new supporting point:
Always On PoE, Quick PoE, LED control, and improved performance with faster CPU and boot times help reduce downtime and simplify operations
Advanced smart-managed Layer 2+ switching with 1G, 2.5G, 5G, and 10G connectivity options for higher-performance SMB and mid-market deployments
Built-in static routing and wire-speed inter-VLAN connectivity help optimize local traffic and reduce dependency on the core firewall for internal traffic flows
Select models deliver HPE Smart Rate multi-gigabit ports up to 10G and Class 6 PoE support to power next-generation Wi-Fi, advanced cameras, and demanding IoT devices
Advanced security includes TPM 2.0, TACACS+, AAA authentication and accounting, management access controls, ACLs, and stronger device integrity protections
Cloud, mobile, and local management are enhanced by Direct Ops Commands, SNMP read-only cloud access, and richer diagnostics for faster troubleshooting
