HPE J9311A ProCurve 48-Port Managed Ethernet Switch

HPE J9311A 3500‑48G‑PoE+ yl Switch

Overview

The HPE J9311A is a managed access‑layer switch intended for enterprise network environments that require 48 10/100/1000 Base‑T PoE+ ports with the flexibility to add 10‑Gigabit uplink modules for future growth. It supports up to 4 10 GbE ports via the optional yl module slot, enabling migration toward higher‑speed uplinks while maintaining dense Gigabit edge connectivity. Designed to fit in a 1 RU rack‑mount footprint, the switch is well suited for wiring closets, branch offices or campus floor access layers. It integrates advanced Layer 2‑plus features including static routing, dual‑personality ports, PoE+ support and expansion slot capability, delivering a forward‑looking access platform that protects investments in client‑side Gigabit connectivity but allows uplink scaling. Management is via CLI, web GUI, SNMP and RMON, with support for PoE budget management, intelligent power control and advanced QoS and security features.
