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:
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
Always On PoE, Quick PoE, LED control, and improved performance with faster CPU and boot times help reduce downtime and simplify operations
