HPE FlexNetwork 5140 48G 4SFP+ EI switch - 48x Gigabit Ethernet, 4x 10G SFP+ uplinks, Layer 3 smart managed, rack-mountable

The HPE FlexNetwork 5140 48G 4SFP+ EI switch stands out by combining enterprise-class Layer 3 routing with a compact 1U footprint, delivering wire-speed performance for demanding campus and branch networks. Unlike basic Layer 2 switches, this model supports OSPF, RIP, and BGP, enabling dynamic routing and efficient traffic segmentation without additional hardware.

Highlights

• 48 x 10/100/1000Base-T RJ-45 ports for high-density Gigabit connectivity
• 4 x 1/10 Gigabit Ethernet SFP+ uplink ports for flexible fiber or copper uplinks
• Layer 3 smart managed with static routing, RIP, OSPF, BGP, and ECMP
• 176 Gbps switching capacity and 130.9 Mpps throughput for non-blocking performance
• Advanced security: ACLs, 802.1X, port security, DHCP snooping, IP Source Guard
• Energy-efficient IEEE 802.3az support reduces power consumption during low activity

In daily use

Deploy this switch at the aggregation or access layer where high port density and routing intelligence are required. The 48 Gigabit ports easily accommodate IP phones, access points, and workstations, while the four SFP+ uplinks provide 10G connectivity to the core. Manage the device via CLI, web GUI, or SNMP, and leverage features like VLANs, QoS, and jumbo frames up to 9216 bytes to optimize traffic for voice, video, and data. Redundancy protocols such as RSTP, MSTP, and LACP ensure network resilience, and the internal AC power supply simplifies installation in standard racks.
