- HP J9981A#B2E | OfficeConnect 1820 Series 1820-48G 48 x 10/100/1000Base-T RJ-45 and 4 x SFP (mini-GBIC) Ports Layer 2 Managed Gigabit Ethernet Network Switch
- HP OfficeConnect 1820-48G (J9981A#B2E) is a solid pick for organizations running virtualization clusters, NAS arrays or render farms that need low-latency, high-bandwidth links that don't want to overthink the network layer. Data centers and server rooms running virtualization hosts, NAS/SAN backbones, render farms or AI/ML training nodes are the natural fit, since all of them move heavy traffic between servers. It also works well aggregating traffic from smaller access-layer switches. It brings 52 total network ports, laid out as 48xGigabit EthernetRJ-45 and 4xGigabit EthernetSFP (mini-GBIC), topping out at Gigabit (1GbE) per port. Layer 2 switching keeps things fast and simple: MAC-address forwarding and VLAN segmentation. It rounds this out with SFP (mini-GBIC) expansion for uplinks. Firmware and configuration live in onboard non-volatile memory, surviving reboots and power cycles. On the compatibility side, it's rack-mount, in a 1U footprint, a 19-inch rack fit, takes ac input power, and uses standard front-to-back airflow to match common data-center airflow layouts. Also, twisted pair media over SFP (mini-GBIC) covers both copper and fiber runs. Buy the HP OfficeConnect 1820-48G from GotoDirect for a genuine, factory-sealed unit with straightforward warranty terms and quick nationwide shipping.
