Frequently asked questions
What is the switching capacity and forwarding performance of the Aruba CX 6000 48G?
The CX 6000 delivers 104Gbps non-blocking switching capacity with 77.3 Mpps (million packets per second) forwarding performance. Latency is sub-2 microseconds (1.9μs at 1Gbps), enabling wire-speed forwarding across all 48 ports simultaneously without congestion or packet loss in typical campus deployments.
How much Power over Ethernet (PoE) does this switch provide?
The R8N85A#ABA provides 370W total PoE budget supporting Class 4 PoE+ on all 48 Gigabit Ethernet ports. This enables powering of high-power devices like enterprise access points, IP phones, and IoT sensors requiring up to 30W per port, with intelligent power management and prioritization.
What uplink options are available for core network connectivity?
The switch includes 4 SFP (mini-GBIC) slots supporting Gigabit Ethernet fiber optics (1000Base-X). These can be populated with SFP transceivers for fiber uplinks to core switches, providing flexible aggregation connectivity without consuming Gigabit Ethernet ports.
Is this switch suitable for fanless deployment in office environments?
Yes. The CX 6000 is completely fanless with side-to-side airflow design, consuming only 30.6W typical power. This makes it ideal for quiet office, branch, and edge deployments where acoustic noise is a concern, while maintaining enterprise-class performance and reliability.
What management and monitoring capabilities does the switch offer?
Management options include Web GUI, CLI, Aruba Central cloud-based management, and on-premise management. Remote access via SNMP 1/2c/3, HTTPS, RADIUS, and REST APIs enables programmable network automation. LLDP-MED support provides automatic discovery and configuration of connected devices.
What Layer 3 routing and security features are supported?
The switch supports static routing, comprehensive VLAN support (up to 16 SVIs), Access Control Lists (ACLs) for ingress filtering, QoS with DiffServ, LACP link aggregation, RSTP/MSTP spanning tree protocols, and IPv6 addressing. MAC address table supports 8,192 entries with 512 IPv4 and 512 IPv6 unicast routes.
What is the physical form factor and power requirements?
The switch is a 1U rack-mountable device (17.4" W x 12" D x 1.7" H) weighing 11.07 lbs. It requires AC 100-240V (50/60 Hz) input with single internal power supply. Typical power consumption is 30.6W, with maximum PoE delivery of 370W, totaling approximately 400W peak under full load.
