HPE S1T82A 6-Slot 4-Post Rack Mount Kit

Overview

The S1T82A is the rack mounting kit designed to install the HPE Aruba Networking CX 5420 6-slot chassis switch into a standard 4-post equipment rack. If you're deploying the CX 5420 in a structured rack environment — data center row, IDF closet, or network core — this kit provides the hardware needed to seat and secure the chassis properly rather than relying on improvised mounting solutions that compromise airflow and cable management.

Compatibility

Designed specifically for the HPE Aruba Networking CX 5420 6-slot modular chassis switch. Fits standard 19-inch 4-post equipment racks. Verify rack post depth and spacing against the CX 5420 chassis dimensions before ordering — the 4-post design assumes a rack with both front and rear post support, and is not intended for 2-post relay-style mounting.

Installation Notes

Confirm your rack's internal usable depth accommodates the CX 5420 chassis with this kit installed. The 4-post configuration requires rear-post attachment points in addition to standard front-mount ears, so open-frame 2-post racks are not supported. Install the chassis according to HPE's published torque and mechanical guidelines for the CX 5420 platform to avoid chassis flex or port misalignment on line card installation.
