HPE Aruba Networking CX 9300S 32-port (100G) + 8-port (400G) Switch

The HPE Aruba Networking CX 9300S 32-port (100G) + 8-port (400G) Switch (HPE Aruba Networking CX 9300S 32p QSFP28 100G + 8p QSFP-DD 400G (Front-to-Back, 6 Fans, 2 AC PSU) Bundle) is a fixed 1U high-performance switch optimized for data center leaf/spine roles.

It supports 32 ports of 100G (via QSFP28) and 8 ports of 400G (via QSFP-DD), offers robust bandwidth (up to 25.6 Tbps in the CX 9300 family), MACsec encryption, VSX redundancy, and full Layer 2 / Layer 3 features under Aruba’s AOS-CX OS.

Detailed Specifications

Port & Interface Configuration

• 32 × QSFP28 ports (supporting 100G, and via breakout possibly 4×25G)
• 8 × QSFP-DD ports (supporting 400G, and likely breakout to multiple 100/200G links)
• All ports operate at line rates with no oversubscription
• Some ports support MACsec encryption for secure link-level communication

Performance & Fabric

• Switching capacity: up to 25.6 Tbps for the CX 9300 family (fixed 1U switches)
• Forwarding performance: up to 5 Bpps (billion packets per second) in the series
• Low-latency forwarding suitable for high-throughput fabrics
• Packet buffer architecture designed to absorb transient bursts

Redundancy & High Availability

• Dual AC power supplies (hot-swappable)
• 6 hot-swappable fans for efficient cooling and redundancy
• VSX (Virtual Switching Extension) support for active-active redundancy, hitless upgrade paths, and high resilience

Layer 2 / Layer 3 Features & Security

• Layer 2: VLAN, Spanning Tree (RSTP/MSTP), link aggregation (LACP), IGMP snooping
• Layer 3: Static routing, OSPF, BGP, VRF, policy-based routing, IPv4 and IPv6 support
• Overlay / Fabric support: VXLAN / EVPN for modern fabric architectures
• Access Control Lists (L2–L4), MACsec encryption on supported ports, control-plane hardening

Physical & Environmental

• Form factor: 1U fixed chassis
• Airflow: Front-to-back (as bundle specifies “Front-to-Back”)
• Rack-mountable (standard 19-inch racks)
• Operational ranges suitable for data center environments

Key Features

• 32 × 100G QSFP28 ports + 8 × 400G QSFP-DD uplink/backbone ports
• Up to 25.6 Tbps switching capacity and multi-billion packet throughput
• Support for MACsec, VSX, and advanced fabric architectures
• Redundant power and cooling with hot-swappable fans/PSUs
• Full Layer 2 + Layer 3 feature set including VXLAN/EVPN, OSPF, BGP

Meta Description

The HPE Aruba Networking CX 9300S 32-port (100G) + 8-port (400G) Switch delivers high throughput, MACsec support, VSX high availability, dual AC power, and full Layer 3 capabilities — ideal for data center spine or leaf roles in modern campus and enterprise networks.
