FAQ
How many devices can this switch power with PoE+?
The HPE Aruba 3810M 48G PoE+ switch provides Power over Ethernet Plus on all 48 ports, supporting IEEE 802.3at standards. The total PoE budget depends on the specific power supply configuration, but it is designed to deliver up to 30W per port for devices like IP phones, wireless access points, and security cameras. For exact power budgeting, refer to the product datasheet for detailed wattage allocations per port.
What types of uplink modules are compatible with the expansion slot?
The switch features one modular expansion slot that accepts HPE Aruba-specific uplink modules, including SFP, SFP+, and 10GbE transceivers for fiber or copper connections. This allows network administrators to customize uplink capacity based on backbone requirements, such as adding fiber optics for long-distance links or high-speed copper for short-range connections between switches.
Can this switch be stacked with other HPE Aruba switches?
Yes, the HPE Aruba 3810M includes a dedicated stack port that enables stacking with compatible Aruba switches. Stacking allows multiple physical switches to be managed as a single logical device, simplifying configuration, monitoring, and firmware updates. This feature is particularly useful for expanding port count without complex standalone switch management across large networks.
What management features does this Layer 3 switch offer?
As a Layer 3 managed switch, it supports advanced routing protocols like OSPF and static routing, VLAN management with inter-VLAN routing, Quality of Service (QoS) for traffic prioritization, and security features such as ACLs and port security. Management can be performed via CLI, web interface, or network management systems like Aruba Central for centralized oversight.
Is this switch suitable for rack mounting in a data center?
Absolutely. The switch is designed with a 1U rack-mountable form factor, compatible with standard 19-inch server racks. Its dimensions (1.73" H x 17.42" W x 16.98" D) ensure it fits neatly in rack cabinets, and the front-to-back airflow aligns with typical data center cooling designs. The robust construction supports stable operation in rack environments with proper cable management.
Does the switch support redundant power for high availability?
Yes, the HPE Aruba 3810M supports redundant power supply configurations. While it includes a built-in power supply, it is compatible with external redundant power supply units that can be added for failover protection. This feature ensures continuous operation in case of a power supply failure, making it suitable for critical network segments where uptime is essential.
