HPE Aruba Networking 2930F JL557A 48-Port PoE+ 740 W Switch with 4x 1G SFP
- Managed, Rack-mountable, 48 x 1G PoE+ ports, 4 x 1G SFP Uplinks, PoE+ (740W), Layer 3
Overview
The HPE Aruba Networking 2930F series is HPE's access switch line for smart digital workplaces with an integrated wired and wireless approach, pairing built-in uplinks and VSF stacking with an HPE Aruba Networking ProVision ASIC and a feature set HPE describes as requiring no software licensing. The JL557A is the 48-port PoE+ model with the 740 W budget, twice the 370 W of the standard 48-port PoE+ models, paired with four 1G SFP uplinks for closets that uplink at 1 Gigabit. HPE markets the series as Layer 3, but its OSPF is Access OSPF, limited to one area and 8 interfaces, so the JL557A fits routed access at the network edge rather than a routed core. It can be managed from cloud-based HPE Aruba Networking Central or on-premises AirWave, and HPE supports moving between the two without replacing the switch.
Technical Details
The HPE Aruba Networking 2930F JL557A (2930F 48G PoE+ 4SFP 740W Switch) is a Layer 2+ managed 1U rackmount switch with 48 Gigabit PoE+ access ports and 4x 1G SFP uplinks, running HPE Aruba Networking OS-Switch. Unicast routing is limited to static, RIP and single-area Access OSPF (up to 8 interfaces). Switching capacity is 104 Gbps and forwarding rate is 77.4 Mpps. The PoE+ budget is 740 W (IEEE 802.3at, up to 30 W per port); HPE publishes no higher figure with added power supplies. It supports Virtual Switching Framework (VSF) stacking of up to 8 switches; HPE publishes no VSF bandwidth. It powers wireless access points, IP phones and IP cameras in campus and branch wiring closets.
Best For
The JL557A suits campus and branch wiring closets that power wireless access points, IP phones and IP cameras and use 1-Gigabit SFP uplinks. A 740 W PoE+ budget is suitable for mixed deployments of these devices; actual device counts depend on each powered device's power draw.
Not suitable if:
- you need 10-Gigabit uplinks, since the four uplinks are 1G SFP slots
- you need more than 30 W on a port, since the ports are IEEE 802.3at PoE+
- you need multi-area OSPF or other full dynamic routing, since Access OSPF is limited to one area and up to 8 interfaces
- you need multigigabit access ports, since all access ports are 10/100/1000

FAQ
Does the HPE Aruba Networking 2930F JL557A support PoE+, and what is its power budget?
Yes. All 48 Gigabit access ports on the HPE Aruba Networking 2930F JL557A support IEEE 802.3at PoE+ at up to 30 W per port, for devices such as wireless access points, IP phones and IP cameras. The total PoE+ budget is 740 W, shared across all ports, so the budget rather than the port count limits how many devices draw full power. HPE publishes no second-power-supply option or higher PoE figure for this model.
What uplinks and transceivers does the JL557A use?
The JL557A has four fixed SFP uplink ports that run at up to 1 Gigabit. HPE lists 1G SFP optics for them (SX, LX, LH and a 1G RJ45 copper SFP) plus a 100M FX SFP. They are not SFP+ ports, so 10G SFP+ optics are not supported on this model; the 10-Gigabit option in the series is the SFP+ uplink models. Transceivers are sold separately.
How many JL557A switches can you stack?
Up to eight. The JL557A supports HPE Aruba Networking Virtual Switching Framework (VSF), front-plane stacking that joins up to 8 switches in a ring or chain topology into one virtual switch managed as a single chassis, with link aggregation across stack members. HPE notes that VSF requires HPE Aruba Networking OS-Switch 16.06 software. HPE does not publish a VSF stacking bandwidth or a cross-series stacking statement for the 2930F.
What is the difference between the JL557A and the JL558A?
Both are 48-port PoE+ 2930F switches with a 740 W PoE+ budget and the same published dimensions and weight. Differences documented by HPE include the uplinks and capacity: the JL557A has four 1G SFP uplinks, 104 Gbps of switching capacity and 77.4 Mpps forwarding, while the JL558A has four 1G/10G SFP+ uplinks, 176 Gbps and 112.0 Mpps. Choose the JL557A when 1-Gigabit uplinks are enough and the JL558A when you need 10-Gigabit uplinks.
Is the JL557A a Layer 3 switch, and what routing does it support?
It supports limited routing. HPE markets the 2930F as a Layer 3 series, but the JL557A's routing is static IP routing with ECMP (256 static routes), RIPv1, RIPv2 and RIPng (10,000 RIP routes), and Access OSPF: OSPFv2 and OSPFv3 between the access layer and the next layer, limited to one OSPF area and up to 8 interfaces. It also offers policy-based routing (up to 16 next-hop routes), PIM Sparse and Dense mode (up to 16 interfaces) and VRRP (up to 128 virtual routers). It is not suited to multi-area OSPF designs or a routed core.
How is the JL557A managed?
The JL557A is a fully managed switch running HPE Aruba Networking OS-Switch. HPE lists command-line, web browser, configuration menu and SNMP management, plus cloud-based HPE Aruba Networking Central and on-premises AirWave, with no hardware change needed to move between them. Zero Touch Provisioning and a built-in REST API support automated deployment, and a dual-personality console port (RJ-45 or USB micro-B) provides local serial access. HPE states that the 2930F feature set requires no software licensing.
What condition is the JL557A sold in, and what warranty applies?
The JL557A is sold new and factory-sealed. It is covered by the Network Devices Inc. 1-year warranty and a 30-day return policy.
