48-port Gigabit PoE+ access switch

The HP Aruba 2930F JL557A provides 48 Gigabit Ethernet ports with Class 4 PoE+ support and a single module slot for uplink expansion. It delivers a switching capacity of 336 Gbps and a forwarding rate of 250 Mpps in a 1U rack-mount chassis weighing 10.36 lb. The switch runs Layer 3 firmware with RIP and OSPF support and requires no separate software licensing.

Suited for wired digital workplaces needing PoE+

This switch fits enterprise edge, SMB and branch offices that power access points, cameras or phones over up to 740 W of PoE+ budget and want cloud or on-premise management via Aruba Central, AirWave or ClearPass. It is not for buyers who need higher port density than 48 ports, 25 GbE or 40 GbE uplinks, or a deeper feature set such as EVPN-VXLAN or MPLS.

One module slot enables flexible uplink choices

The single expansion slot accepts compatible 1 GbE or 10 GbE uplink modules so you can tailor uplinks to the site without replacing the switch. Virtual Switching Framework lets up to four chassis stack logically for simplified control-plane management. Zero Touch Provisioning and Aruba Central cloud onboarding reduce initial configuration effort.

Questions about this item

What uplink module do I need to add 10GbE uplinks to the single module slot?

Insert a compatible Aruba 2930F uplink module into the single module slot to provide 1GbE or 10GbE uplinks as required.

Does the 740 W PoE+ budget cover all 48 ports at Class 4 simultaneously?

The 740 W PoE+ budget supports up to 48 Class 4 PoE ports; actual simultaneous ports depend on each device's power draw.

How do I confirm the switch is forwarding at the rated 250 Mpps throughput after setup?

Monitor the forwarding rate via Aruba Central, AirWave, or the CLI; sustained traffic should approach 250 Mpps under load.
