User Manual
FAQ
What speeds do the 16 QSFP28 ports on this switch support?
Each of the 16 QSFP28 ports supports auto-negotiation across five Ethernet speeds: 1 Gigabit Ethernet (GbE), 10 GbE, 25 GbE, 40 GbE, and 100 GbE. This flexibility allows you to use the same port for different connection requirements, from legacy 1GbE links to modern 100GbE spine connections, without changing hardware as your network evolves.
Does this switch support Layer 3 routing?
Yes, the Aruba CX 8325H is a Layer 3 switch. It provides advanced IP routing capabilities, including static routing, policy-based routing, and support for routing protocols. This enables it to function as a routing node within your network, facilitating segmentation between VLANs, departments, or data center tiers for improved security, traffic management, and scalable network design.
What is the purpose of the back-to-front airflow design?
The back-to-front airflow design aligns with common data center cooling architectures where cold air is supplied through raised floors or front aisles and hot air is exhausted to the rear. This switch pulls cool air from its front (port side) and exhausts warm air out the rear (power supply side), ensuring efficient heat dissipation and predictable thermal performance when installed in standard racks, preventing hot spots and maintaining component reliability.
How many power supplies are included, and are they redundant?
The switch comes with two AC power supplies pre-installed. These power supplies are hot-swappable and support N+N redundancy. This means if one power supply fails or is removed for maintenance, the other can continue to power the switch fully without interruption, providing high availability for critical network operations.
What does TAA compliance mean for this switch?
TAA (Trade Agreements Act) compliance certifies that this switch is manufactured or substantially transformed in a designated country, making it eligible for purchase by U.S. federal government agencies and other entities bound by TAA procurement rules. This compliance is essential for sales into government, education, and certain institutional markets where sourcing regulations are strictly enforced.
Can this switch be stacked with other Aruba switches?
Yes, the switch includes a stack port, allowing you to connect multiple Aruba CX 8325H switches (or compatible models) together to form a logical stack. Stacking simplifies management by presenting multiple physical switches as a single entity, enables centralized configuration, and can provide increased port capacity and resilience through inter-switch links, making network expansion and maintenance more efficient.
What uplink, SFP, fiber, or media support detail is listed?
The warranty or support detail listed is Optical Fiber, giving buyers a clearer picture of expected coverage after purchase.
What management, monitoring, or control option is listed?
Gigabit Ethernet,10 Gigabit Ethernet,25 Gigabit Ethernet,40 Gigabit Ethernet,100 Gigabit Ethernet.
