Aruba 5406R zl2 6-Slot Switch Chassis

The HPE Aruba J9821A switch chassis serves as the robust base for the 5400R zl2 modular switch family. With room for up to six plug‑in modules, it supports high-density deployment of Gigabit, 10 GbE, PoE+, and 40 GbE network access—perfect for campus, data center edge, or enterprise backbones that demand scalability, resiliency, and advanced control. 

Features :

Based on the powerful sixth-generation ProVision ASIC and delivering a massive 2 Tbps crossbar fabric at 2.1 µs latency, the J9821A chassis offers exceptional performance. . Equipping up to six modules—including PoE+, SFP+, QSFP+, and Smart Rate expansion cards—provides tailored connectivity (up to 96×10 GbE, 288×1 GbE). Dual PSU slots and fan trays ensure operational reliability and redundancy.

Advanced Options :

Featuring Virtual Switching Framework (VSF) with hitless failover, the chassis can integrate multiple units under one management plane for high availability.  It also supports SDN/OpenFlow, IPv4/IPv6 routing, OSPF, BGP, QoS, and security tools—all license-free.
