48-port PoE+ switch for dense deployments

The HPE Aruba 2930F JL558A#ABA provides 48 autosensing RJ-45 ports with PoE+ support alongside four SFP+ uplinks. It suits offices and campuses that need to power phones, cameras or access points from the switch itself. The desktop form factor fits standard racks or shelf mounting. Total power consumption reaches 980 W at maximum load.

Uplink and PoE limits

Each copper port negotiates 10, 100 or 1000 Mbps while the SFP+ slots accept 1 or 10 GbE modules without on-board PHY. PoE+ follows IEEE 802.3at so the 740 W budget is shared across all 48 ports, not guaranteed per port. Devices requiring more than 30 W per port will exceed the standard this switch implements.

Desktop chassis with modular stacking

The unit measures 1.73 by 17.42 by 12.77 inches and weighs 10.56 lbs, using a 1U desktop profile. Front-facing RJ-45 and SFP+ ports keep patch cables accessible in tight racks. A modular stacking port allows the switch to join a single management plane with compatible peers. No redundant power supply is included in this model.

Questions about this item

Should I pick the 48-port PoE+ model or a smaller version?

This unit provides 48 RJ-45 ports with PoE+ plus four SFP+ uplinks; choose it when you need that many powered connections in one chassis.

What does the 740 W PoE budget deliver in a live rack?

It powers all 48 ports at up to 30 W each simultaneously, with headroom for the switch's own 980 W maximum draw.

How do the four SFP+ ports limit real-world uplink speed?

Each SFP+ cage runs at 1 or 10 GbE, so aggregate uplink throughput caps at 40 Gbps when all four are populated.
