Switch gerido L3 HP Enterprise HPE FlexNetwork 5140 48G PoE+ 4SFP+ EI — 48 portas Gigabit PoE+, 4 portas SFP+

The HPE FlexNetwork 5140 48G PoE+ 4SFP+ EI is a managed Layer 3 Ethernet switch designed for medium and large enterprise campus access layers. It provides 48 Gigabit RJ-45 ports with PoE/PoE+ support and four fixed SFP+ uplinks for 10Gb connectivity. The switch supports a 16,384-entry MAC table, 176 Gbit/s switching capacity, full-duplex switching and is rack-mountable in 1U, making it suitable for access aggregation, IP telephony and small datacenter edge deployments.

Advantages

The switch delivers scalability and high availability through Intelligent Resilient Fabric (IRF) stacking, allowing multiple units to operate as a single logical switch and router. It includes enterprise-class security and QoS features such as ACLs, 802.1X, MAC authentication, dynamic ARP protection and advanced classifier-based QoS. Management options include an embedded Smart Management Center for centralized on-box control and compatibility with HPE Intelligent Management Center (IMC) for broader network visibility. Energy Efficient Ethernet and a variety of link redundancy protocols help reduce operational cost and improve uptime.

Suitable for

• Enterprise access layer deployments requiring PoE/PoE+ for IP phones and wireless access points
• Aggregation at the edge of small datacenter or campus networks
• Environments needing advanced QoS and security features (ACLs, 802.1X, ARP protection)
• Networks that benefit from stacking and centralized management via IRF or IMC

When it may not be suitable

This switch is not targeted at small home or very small office environments where 48 ports, PoE+ capacity and advanced L3 features would be unnecessary and cost-inefficient. For deployments requiring very high non-blocking switching capacity or modular flexibility beyond fixed-port designs, a higher-capacity or modular chassis switch may be more appropriate.

Key specifications

• Ports: 48 x 10/100/1000 RJ-45 (PoE/PoE+)
• Uplinks: 4 x SFP+ (10Gb)
• Switching capacity: 176 Gbit/s
• MAC address table: 16,384 entries
• PoE budget: up to 370 W (PoE+ support)
• Management: embedded Smart Management Center, compatible with HPE IMC
• Layer support: Layer 2 switching, static Layer 3 routing and RIP
• Stacking: HPE Intelligent Resilient Fabric (IRF)
• Weight: 6 kg
• Standards: support for IEEE 802.3 family (incl. 802.1Q, 802.1X, 802.3at, 802.3af, 802.3ae)

How to use

Install the switch in a standard 19-inch rack (1U) using included mounting hardware and connect power. Connect access devices to the 48 Gigabit RJ-45 PoE+ ports and use the four SFP+ uplinks for 10Gb aggregation links. Configure basic network settings, VLANs, QoS and security policies via the web-based Smart Management Center or HPE IMC for centralized management. If required, provision IRF stacking to combine multiple switches into a single logical device for simplified management and higher availability.

What to consider before purchase

• Whether 48 PoE/PoE+ ports and up to 370 W PoE budget meet your powered device requirements
• Need for 10Gb SFP+ uplinks for aggregation or high-bandwidth uplinks
• Requirement for Layer 3 routing capabilities (static routes and RIP) versus full dynamic routing
• Rack space (1U) and weight (approximately 6 kg) for installation
• Management preference: local SmartMC versus centralized HPE IMC integration

Recommendations

For reliable access-layer performance, use the HPE FlexNetwork 5140 48G PoE+ 4SFP+ EI to power IP phones and wireless APs on the Gigabit ports while connecting uplinks with SFP+ modules to your aggregation switches. Enable IRF stacking and centralized management through IMC for simplified operations and faster failover. Configure QoS and ACLs to prioritise voice and control access per user or VLAN.
