User Manual
FAQ
How many PoE+ ports does this switch have?
This HPE switch has 48 Gigabit Ethernet ports that all support PoE+ (Power over Ethernet Plus). This allows you to power devices like IP phones, wireless access points, and security cameras directly through the network cables, eliminating the need for separate power adapters at each device location.
What is the PoE budget of this switch?
The switch provides a total PoE budget of 740 watts. This budget determines how much power is available to distribute across all PoE+ ports simultaneously. With 740W, you can support numerous power-hungry devices, making it suitable for dense deployments like offices with many IP phones or campuses with multiple wireless access points.
What types of uplink options are available?
This switch includes four SFP+ slots for uplink connections. SFP+ slots support 10 Gigabit Ethernet modules, allowing you to use fiber optic or direct-attach copper cables for high-speed connections to core switches, servers, or other network segments. This provides flexibility in backbone connectivity and future scalability.
Is this a Layer 2 or Layer 3 switch?
This is a Layer 3 managed switch. Layer 3 capability means it can perform routing functions between VLANs or subnets, support dynamic routing protocols, and implement access control lists. This makes it suitable for more complex network designs where segmentation and inter-VLAN routing are required, beyond basic Layer 2 switching.
What rack size does this switch fit?
The switch is designed for 1U rack mounting, meaning it occupies one unit of vertical space in a standard 19-inch rack. Its dimensions are 1.73" (43.94 mm) in height, 17.42" (442.47 mm) in width, and 12.77" (324.36 mm) in depth, making it compact and easy to integrate into existing rack infrastructure.
