  • HP JL357A#B2C | Aruba 2540 Series 2540 48G PoE+ 4SFP+ 48 x RJ-45 PoE+ 10/100/1000Base-T and 4 x SFP+ Ports Layer 2 Managed Gigabit Ethernet Network Switch
  • HP Aruba 2540 48G PoE+ 4SFP+ (JL357A#B2C) is the switch IT teams supporting enterprises rolling out PoE access points, IP cameras and phones across large floors often turn to when they need something that just works. It's a good match for IT teams standardizing wiring closets across a campus, schools and offices deploying wireless APs at scale, and security teams running IP camera networks that need power and data on one cable. Facilities with virtualization or NAS traffic riding the same switch will also benefit from the extra headroom. Port-wise, it offers 52 total network ports, laid out as 48xGigabit EthernetPoE+,RJ-45 and 4x10 Gigabit EthernetSFP+,Uplink, topping out at 10GbE per port. Beyond the base ports, there's SFP+ expansion for uplinks. Settings and firmware are stored in onboard non-volatile memory, so they survive reboots and power cycles. PoE+ support means powered endpoints - APs, cameras, phones - plug straight into the switch without extra adapters. Layer 2 switching keeps things fast and simple: MAC-address forwarding and VLAN segmentation. For installation, it's rack-mount, in a 1U footprint, compatible with standard 19-inch racks, runs on ac input power, and moves air side-to-side airflow for straightforward rack cooling. Also, built-in console access plus a USB port makes setup and firmware recovery easier; twisted pair,optical fiber media over SFP+ covers both copper and fiber runs. Buy the HP Aruba 2540 48G PoE+ 4SFP+ from GotoDirect for a genuine, factory-sealed unit with straightforward warranty terms and quick nationwide shipping.
