48-port PoE access switch

The HPE Aruba CX 6100 is a fully managed Layer 2 switch with 48 RJ45 ports and four SFP uplinks. It delivers IEEE 802.3 Class 4 PoE across all copper ports for cameras, access points and other IoT endpoints. The fanless 12-port variant suits quiet workspaces, while this model supports higher-density deployments. No software licensing is required for the included feature set.

Upgrade from unmanaged edge gear

Replacing unmanaged or lightly managed switches adds static routing, ACLs, robust QoS and IPv6 support. The jump is worth it when traffic prioritisation, sFlow visibility or colourless ports with local MAC authentication reduce manual moves, adds and changes. A dedicated ASIC provides low latency of 1.9 µSec at 1 Gbps and 1.8 µSec at 10 Gbps with 98.6 Mpps throughput.

890 W PoE budget and 176 Gbps fabric

The 890 W PoE budget powers all 48 ports simultaneously at Class 4 levels, while the 176 Gbps switching capacity handles aggregation uplinks. Dual-core ARM Cortex-A9 at 1016 MHz with 4 GB DDR3 and 16 GB eMMC runs the AOS-CX operating system. Maximum system draw is 49.7 W. Networks needing Layer 3 routing stacks or higher PoE classes will need a different platform.

Questions about this item

What rack-mount brackets come with the CX 6100 48G switch?

The switch ships with fixed front-mount brackets for a standard four-post rack.

Which step do installers often miss when powering up this switch?

Connecting the AC power cord to a circuit that can deliver the full 740 W PoE budget before enabling the PoE ports.

What component will need replacement after several years of continuous operation?

The internal eMMC storage may wear out after extended use and require a board-level swap.
