What port configuration does the HPE J9021A provide?

The J9021A features 24x 10/100/1000Base-T RJ-45 ports for copper connectivity and 4x dual-personality ports configurable as 10/100/1000 RJ-45 or SFP mini-GBIC slots for fiber uplinks, enabling flexible access and aggregation in SMB networks.

What Layer 2 features are supported on J9021A?

Supports 802.1Q VLANs (up to 256), STP/RSTP/MSTP for loop prevention, IGMPv1/v2 snooping for multicast, port-based ACLs for security, and link aggregation (LACP) for increased bandwidth and redundancy.

What is the switching capacity of the 2810-24G?

Delivers 52 Gbps full-duplex non-blocking switching capacity across all 28 ports, ensuring wire-speed performance for high-traffic SMB environments without bottlenecks.

Can the J9021A be stacked with other switches?

Yes, supports stacking up to 16 units using optional stacking modules, providing unified management, increased port density, and failover capabilities for resilient access switching.

What management options are available?

Offers console CLI, web-based GUI, SNMP v1/v2c/v3, RMON, and syslog; integrates with HP ProCurve Manager for centralized monitoring and configuration in SMB networks.

Is the J9021A suitable for PoE deployments?

Base model is non-PoE but accepts optional PoE modules in dual-personality slots, delivering up to 370W PoE budget for powering IP phones, cameras, or Wi-Fi access points.

Product overview

The HPE ProCurve Switch 2810-24G (J9021A) is a fanless, fully managed Layer 2 Gigabit Ethernet switch designed for small to medium business networks requiring reliable access-layer connectivity. It features 24x auto-sensing 10/100/1000Base-T RJ-45 ports and 4x dual-personality ports that support either 10/100/1000Base-T or SFP mini-GBIC for fiber uplinks, delivering non-blocking 52 Gbps switching capacity. Key capabilities include 802.1Q VLANs (up to 256), QoS with 8 priority queues per port, IGMPv1/v2 snooping for multicast optimization, Spanning Tree Protocol (STP/RSTP/MSTP), and access control lists (ACLs) for security. The switch supports stacking up to 16 units via optional modules for simplified management. Ideal for branch offices, campus wiring closets, and edge deployments, it offers console management, web GUI, and SNMP for configuration. Power consumption is low at 25W typical, with rack-mountable 1U form factor. Though End of Sale, it remains viable for legacy SMB environments needing cost-effective Gigabit switching.
