SKU CH-NJQ2-FV8B2 MPN S0U62A

A modular 24-port Layer 3 switch chassis with six half-width module slots, 1600 W power, and up to 960 Gbps throughput for scalable enterprise networks

  • Layer 3 intelligence with BGP, VSX and OSPF
  • Modular growth via 6 half-width module slots in 4U
  • 960 Gbps switching capacity at 714 Mpps throughput
  • Always-On PoE plus VSX Live Upgrade for high availability
  • Unified AOS-CX OS and Central management simplify operations

Enterprise Layer 3 Switch Chassis

The HP Aruba CX 5420 Switch Chassis is a modular Layer 3 switch designed for enterprise networks that require advanced routing protocols. It supports BGP, VSX and OSPF with robust quality of service for traffic prioritisation. The 4U form factor fits standard racks and includes redundant management modules and power supplies for high availability.

Modular Expansion and Unified Management

Six half-width module slots provide port diversity and allow the chassis to grow with changing connectivity needs. The common AOS-CX operating system delivers a consistent operator experience across the CX portfolio. Management is simplified through Aruba Central, Multi-Edit Software, web GUI or industry-standard CLI with automated role-based policies for users and IoT devices.

High-Capacity Switching Fabric

The Gen7 ASIC architecture delivers up to 960 Gbps switching capacity with 714 Mpps forwarding performance at wire speed. Always-On PoE maintains power to connected devices during firmware upgrades. The 1600 W power budget supports dense PoE deployments while adaptive power consumption optimises efficiency for bandwidth-intensive applications.

Questions about this item

Which components can be swapped without powering down the 24-port chassis?

Redundant management modules and power supplies are hot-swappable, so a failed MM or PSU can be replaced while the switch keeps forwarding traffic.

What throughput ceiling appears first when every module is fully populated?

The backplane caps aggregate switching at 960 Gbps with 714 Mpps, so sustained line-rate traffic across all ports cannot exceed those figures.

How much heat must the rack handle when the 1600 W supply runs continuously?

At full load the chassis draws up to 1600 W, so virtually all of that power becomes heat that the room cooling must remove.
