HPE J9147A

Procurve 2910al-48GE 48Port Gigabit Ethernet Managed Switch

The HPEJ9147A (E2910-48G-al) is a fully managed, stackable Gigabit Ethernet switch offering 48 auto-sensing10/100/1000 RJ-45 ports and 4 dual-personality combo ports that support either copper or SFP mini-GBIC fiber links. Equipped with Layer 2 switching and Layer 3 lite routing (static IP and RIP-1/2), it strikes a balance between affordability and advanced routing capability. Designed for enterprise edge, campus distribution, or remote branch office deployment, the switch delivers solid Gigabit access while supporting optional stacking of up to 16 units×allowing streamlined management via a single IP. Robust feature sets include VLAN support, ACLs, QoS, jumbo frames, IPv6 dual-stack, sFlow telemetry, and enterprise security protocols.

Features

Powered by a dual ARM1156T2S processor at 515 MHz with 512 MB SDRAM and 4 MB flash, the E2910-48G-al delivers reliable performance with a non-blocking 176 Gbps switching fabric and forwarding capacity of up to 131 Mpps (64-byte frames). It supports sub-3 µs latency on 1 GbE and <1.3 µs when uplinks run at 10 Gb/s. The four "dual-personality" ports can be used as standard Gigabit RJ-45 or mini-GBIC SFP ports for fiber connectivity, and optional expansion modules supply up to four 10-GbE uplinks via CX4 or SFP+Software features include static IPv4 routing and RIP-1/2, ACL enforcement, VLAN tagging, QoS support, IPv6 management, sFlow monitoring, and stackable architecture for coverage up to 16 switches

Advanced Options

Security is supported via SSHv2, RADIUS, TACACS+, SSL, and 802.1X. Stackable operation ensures redundancy and unified management. Environmental specs include operating temperatures from 0 to 55 °C and support for up to 95% non-condensing humidity, with an altitude rating up to 3 km The E2910-48G-al switch is engineered for consistent, high-throughput network access with wire-speed forwarding across all Gigabit ports. Its architecture delivers sub-3 µs latency and supports full bandwidth even under heavy traffic loads Stacking via HP IRF-equivalent technology allows deployment of up to 16 units as a logical switch with auto-failover and load distribution. Critical fabric operations×including updates, link failure, or maintenance×can occur with minimal disruption. PoE is optional in other variants; this model focuses on non-PoE access stack deployment.
