Product Features
Technical Overview
At its core, the 2930F switch provides 48 auto-sensing 10/100/1000BASE-T ports, each capable of delivering data and up to 30W of PoE+ power per port, with a total system budget of 740W. This ensures reliable power delivery to connected devices without the need for separate electrical outlets. The integrated 4 SFP slots offer Gigabit Ethernet expansion, supporting both copper and optical fiber connections for long-distance links or high-bandwidth aggregation.
The switch operates as a full Layer 3 device, supporting static routing, RIP, OSPF, and policy-based routing for intelligent traffic flow. It is fully manageable via a web interface, CLI, or HPE's Intelligent Management Center, providing granular control over VLANs, QoS, security policies, and monitoring. The stack port facilitates easy expansion, allowing multiple units to be managed as a single logical switch, simplifying administration and increasing resiliency.

FAQ
What is the total PoE+ power budget of this switch?
The HPE 2930F 48G PoE+ 4SFP Switch has a total PoE+ power budget of 740 watts. This budget is shared across its 48 Ethernet ports, with each port capable of delivering the IEEE 802.3at standard of up to 30 watts to connected devices like IP phones, wireless access points, or security cameras. The switch intelligently manages power allocation, ensuring critical devices receive priority.
How many SFP slots are available, and are they shared with the Ethernet ports?
This switch includes four dedicated SFP (Small Form-factor Pluggable) slots for uplink expansion. These slots are not shared with the 48 Gigabit Ethernet ports; they are separate, providing flexible connectivity options. You can use them for fiber optic connections (like 1000BASE-SX or LX) for longer distances or copper SFP modules for short-haul Gigabit links to other switches or servers.
Does this switch support Layer 3 routing?
Yes, the HPE 2930F is a full Layer 3 managed switch. It supports static routing and dynamic routing protocols including RIP and OSPF. This allows it to perform inter-VLAN routing, implement access control lists (ACLs) for security, and manage traffic flow based on IP addresses, making it suitable for more complex network designs beyond basic switching.
Can multiple units of this switch be stacked together?
Yes, the switch includes a stack port that allows you to connect multiple 2930F switches together to form a stack. This enables you to manage the entire stack as a single logical device through one IP address, simplifying configuration, monitoring, and maintenance. Stacking also increases resiliency and can improve performance by leveraging the combined bandwidth of the stack.
What are the physical dimensions and rack compatibility?
The switch measures 1.73 inches in height, 17.42 inches in width, and 11.98 inches in depth. It is designed to fit a standard 19-inch equipment rack and occupies 1 rack unit (1U) of vertical space. It includes mounting brackets for rack installation and can also be used on a desktop, making it versatile for various deployment scenarios.
What management options are available for this switch?
The switch offers multiple management interfaces: a web-based graphical user interface (GUI) for easy configuration, a command-line interface (CLI) for advanced control, and support for SNMP for network monitoring systems. It is also compatible with HPE's Intelligent Management Center (IMC) for centralized management of multiple HPE networking devices.
What uplink, SFP, fiber, or media support detail is listed?
The warranty or support detail listed is Yes, giving buyers a clearer picture of expected coverage after purchase.
