Frequently Asked Questions
What is the primary function of the HPE Aruba JL081A module? +
The JL081A is a dedicated 4-port PoE+ expansion module designed specifically for Aruba 3810M and 2930M switch series. It enhances your existing infrastructure by adding high-density Power over Ethernet Plus capabilities, allowing you to power devices like IP phones, surveillance cameras, and wireless access points directly through the switch backplane without needing additional injectors.
Which Aruba switch series are compatible with the JL081A module? +
This module is engineered for seamless integration with the Aruba 3810M and 2930M switch families. It utilizes the modular slot architecture on these units to provide flexible port expansion. Always ensure your switch firmware is updated to the latest recommended version to guarantee full feature support and hardware recognition upon installation.
How much power does each port on the JL081A provide? +
The JL081A provides IEEE 802.3at PoE+ power, delivering up to 30 watts per port. This capacity is sufficient to power demanding network endpoints such as high-performance Wi-Fi 6 access points, pan-tilt-zoom security cameras, and VoIP desk phones, ensuring reliable operation even for devices requiring higher power draw than standard PoE.
Does the JL081A support hot-swapping in Aruba 3810M switches? +
Yes, the Aruba 3810M and 2930M architectures are designed to support modular, hot-swappable components. You can install or remove the JL081A module without powering down the entire switch chassis. This capability is essential for minimizing network downtime during hardware upgrades or maintenance in mission-critical enterprise environments.
What is the physical interface type for the ports on the JL081A? +
The JL081A features four 10/100/1000BASE-T RJ-45 ports. These ports support auto-negotiation and auto-MDIX, allowing for easy connection of copper Ethernet cabling. Because they are standard copper interfaces, they are highly versatile for connecting workstations, servers, and various PoE-enabled IoT peripherals throughout your office or data center environment.
How do I manage the PoE settings for the JL081A ports? +
PoE management for the JL081A is handled through the host switch's standard management interfaces, including the CLI, Web UI, or Aruba AirWave and Aruba Central platforms. You can granularly control power allocation, set priorities for specific ports, and monitor real-time power consumption levels to ensure efficient energy utilization across your network fabric.
Does the JL081A module impact the total PoE budget of my Aruba switch? +
While the JL081A adds physical PoE+ ports, the total available PoE budget for the switch remains dependent on your installed power supplies. When adding this module, verify that your current power supply unit (PSU) configuration can accommodate the aggregate power requirements of all connected PoE devices to prevent power-related port shutdowns.
Is the JL081A appropriate for high-density edge deployments? +
The JL081A is an excellent choice for edge deployments where increasing port density is required without replacing the entire switch chassis. Its PoE+ functionality makes it ideal for wiring closets serving busy office floors, enabling centralized power management for a wide array of network-connected hardware while maintaining the scalability of your existing Aruba infrastructure.
How can I obtain a bulk quote for multiple JL081A modules? +
