J9546A Use Case
Data Center Spine-Leaf 10G Copper Interconnect
Scenario: An enterprise deploys Aruba 8400 switches in a leaf-spine fabric and installs the J9546A-Aruba 8-port 10GBASE-T v2 zl Module for eight 10G RJ-45 uplinks over Cat6a. Benefit: Eliminates SFP+ optics spend, speeds rollout with familiar copper, delivers line-rate, low-latency switching to support high-performance virtualization and storage east-west traffic.
Campus Aggregation of 10G Copper Edge Connections
Scenario: A large university uses Aruba 8320 aggregation switches fitted with the J9546A-Aruba 8-port 10GBASE-T v2 zl Module to connect dozens of building-level access switches over existing Cat6a cabling. Benefit: Leverages installed copper infrastructure, reduces CapEx, simplifies maintenance, and scales 10G service delivery to wireless controllers, IP telephony, and research labs without recabling.
Hyperconverged Virtualization Cluster Connectivity
Scenario: A mid-market data center runs a Nutanix hyperconverged cluster on Aruba CX 6400 switches with the J9546A-Aruba 8-port 10GBASE-T v2 zl Module to link eight server nodes at 10G over Cat6a. Benefit: Provides high-bandwidth, low-latency host-to-switch paths, accelerates VM migrations, optimizes storage I/O, and maximizes ROI by avoiding fiber transceivers.
