HPE Aruba Networking 2930M JL321A 48-Port Gigabit Data Switch with 1 Modular Uplink Slot
- Managed, Rack-mountable, 48 x 1G ports, 4 x 1G combo SFP/RJ-45 ports (shared), No PoE (Data Only), Layer 3
Overview
The HPE Aruba Networking 2930M Series is an access-layer switch family that HPE positions for smart digital workplaces with integrated wired and wireless policy through ClearPass Policy Manager and dynamic segmentation. The JL321A is the 48-port data-only configuration, and its single uplink slot lets backhaul move from 1GbE or 10GbE to 40GbE by changing the module rather than the switch. Its routing is built for routed access toward the next layer of the LAN rather than for core routing. An optional second hot-swappable power supply and VSF stacking let a dense closet grow and stay serviceable.
Technical Details
The HPE Aruba Networking 2930M JL321A is a Layer 2+ managed 1U switch with 48 Gigabit Ethernet ports, four of them combo RJ-45/SFP, and one modular uplink slot for 10GbE SFP+, Smart Rate or 40GbE QSFP+. Switching capacity is 176 Gbps and forwarding rate is 112 Mpps. It carries no Power over Ethernet, so all 48 access ports are data-only. Routing covers static, RIP and single-area Access OSPF. It supports VSF backplane stacking of up to 10 members at 100 Gbps per switch. It connects desktops, printers and wired IoT devices in higher-density campus and branch wiring closets.
Best For
The JL321A suits higher-density campus and branch wiring closets that connect many non-powered endpoints such as desktops, printers and wired IoT devices and want routed access at the edge. The uplink slot takes a 10GbE SFP+, Smart Rate or 40GbE QSFP+ module, and VSF stacking joins up to 10 switches into one logical chassis.
Not suitable if:
- you need to power access points, IP phones or IP cameras, since this model has no Power over Ethernet
- you need BGP or multi-area OSPF, because routing is limited to static, RIP and single-area Access OSPF
- you need multigigabit access ports, since all 48 access ports are Gigabit
- you need a DIN-rail or hardened industrial switch, since this is a 1U rack-mount campus switch

FAQ
Does the HPE Aruba Networking 2930M JL321A support PoE?
No. The HPE Aruba Networking 2930M JL321A is a data-only switch: HPE lists its PoE power as N/A, so none of its 48 Gigabit ports can power access points, IP phones or IP cameras. Even an HPE Smart Rate uplink module receives no PoE power on this model. If the access ports must deliver PoE+, the closest sibling is the 2930M 48G PoE+ 1-slot Switch, JL322A, which keeps 48 Gigabit ports and the single uplink slot and adds IEEE 802.3at PoE+.
What uplink modules and transceivers does the JL321A use?
The JL321A has one uplink slot that holds one module at a time: the JL083A 4-port 100M/1G/10G SFP+ MACsec module, the JL081A 4-port 1/2.5/5/10GbE HPE Smart Rate module, which receives no PoE power on this data-only switch, or the JL078A 1-port 40GbE QSFP+ module. The slot ships empty. The four combo ports take 100 Mbps or 1G SFP transceivers only; 10G SFP+ optics need the JL083A module. HPE's QuickSpecs state that installing the JL308A, JH231A, JH232A or JH233A 40G QSFP+ transceivers lowers the switch's operating range to 0 to 50 °C (32 to 122 °F); HPE's data sheet names the J9150A, J9151A, J9152A and J9153A 10G SFP+ transceivers for the same 0 to 50 °C limit. HPE lists the supported optics in the 2930M QuickSpecs. Transceivers are sold separately.
Can the JL321A be stacked?
Yes. The JL321A supports HPE Aruba Networking Virtual Switching Framework (VSF) backplane stacking of up to 10 switches in a ring or chain topology, and the stacked switches act as a single chassis. Stacking throughput is up to 100 Gbps per switch, with each port of the 2-port stacking module carrying up to 25 Gbps in each direction. Each member needs the JL325A 2-port Stacking Module and stacking cables (J9734A 0.5 m, J9735A 1 m or J9736A 3 m), which are sold separately.
Does the JL321A support BGP or full OSPF?
No. The JL321A does not support BGP. Its Layer 3 feature set is static routing with ECMP, RIPv1, RIPv2 and RIPng, Access OSPF (OSPFv2 and OSPFv3 limited to one OSPF area and up to eight interfaces), policy-based routing limited to 16 next-hop routes, VRRP, and PIM sparse and dense mode multicast routing. That makes it suited to routed access toward the next layer of the LAN rather than to core or multi-area routing.
What is the difference between the JL321A and the JL319A?
The two are closely matched 2930M data-only switches with one uplink slot, VSF stacking and the same JL085A power supply option. Differences documented by HPE include size and throughput: the JL321A has 48 Gigabit ports, 176 Gbps of switching capacity and a 112 Mpps forwarding rate, while the JL319A has 24 Gigabit ports, 128 Gbps and 95.2 Mpps. The JL321A weighs 10.14 lbs and the JL319A 9.81 lbs. Choose the JL319A when 24 access ports are enough.
Does the JL321A come with a power supply?
No. The JL321A has two power supply slots and ships with no power supply. HPE lists the JL085A X371 12VDC 250W 100-240VAC power supply as the compatible unit for this model; one is required and a second can be added for redundancy. The higher-wattage JL086A and JL087A supplies are listed for the PoE models only. HPE recommends matching supplies for full redundancy on a fully populated switch.
What condition is the JL321A sold in, and what warranty applies?
The JL321A is sold new and factory-sealed. It is covered by the Network Devices Inc. 1-year warranty and a 30-day return policy.
