  • HP J9728A#ACJ | Aruba 2920 Series 2920-48G 44 x RJ-45 10/100/1000Base-T and 4 x Dual Personality SFP Ports + 2 x Expansion Module Layer 3 Managed Stackable Gigabit Ethernet Network Switch
  • HP Aruba 2920-48G (J9728A#ACJ) is worth a close look if you're setting up or upgrading a network for IT teams building out server, NAS and storage backbones. 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. Wiring is handled by 55 total network ports, laid out as 48xGigabit EthernetRJ-45 and 4xGigabit EthernetSFP (mini-GBIC),Uplink and 2xExpansion Module and 1xStacking Module, topping out at Gigabit (1GbE) per port. It rounds this out with SFP (mini-GBIC),Stacking Module,Expansion Module expansion for uplinks and stacking so multiple units run as one logical switch. With 1 (GB) of onboard flash, firmware and configuration backups don't depend on a remote server. Layer 3 support means it routes between VLANs on its own rather than forwarding everything to an upstream router. It slots into a standard 19-inch rack in a 1U footprint, without any special hardware, runs on ac input power, and follows standard front-to-back airflow for predictable cooling. Also, built-in console access plus a USB port makes setup and firmware recovery easier; twisted pair,optical fiber media over SFP (mini-GBIC),Stacking Module,Expansion Module covers both copper and fiber runs. Buy the HP Aruba 2920-48G from GotoDirect for a genuine, factory-sealed unit with straightforward warranty terms and quick nationwide shipping.
