Description:
  • HP JL355A | Aruba 2540 Series 2540 48G 4SFP+ 48 x RJ-45 10/100/1000Base-T and 4 x SFP+ Ports Layer 2 Managed Gigabit Ethernet Network Switch
  • HP Aruba 2540 48G 4SFP+ (JL355A) shows up a lot in shortlists for data centers, virtualization hosts and server rooms that need high east-west throughput, and for good reason. 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. Port-wise, it offers 52 total network ports, laid out as 48xGigabit EthernetRJ-45 and 4x10 Gigabit EthernetSFP+,Uplink, topping out at 10GbE per port. It also adds SFP+ expansion for uplinks. Firmware and configuration live in onboard non-volatile memory, surviving reboots and power cycles. Layer 2 switching keeps things fast and simple: MAC-address forwarding and VLAN segmentation. On the compatibility side, it's rack-mount, in a 1U footprint, a 19-inch rack fit, takes ac input power, and uses side-to-side airflow to match common data-center airflow layouts. 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. GotoDirect ships this HP Aruba switch as genuine stock with full warranty backing and fast delivery nationwide.
