HPE DL300 GEN10+ 1U CMA for Rail KIT - P26489-B21

HPE P26489-B21 1U Cable Management Arm and Rail Kit

Overview

The HPE P26489-B21 is a 1U cable management arm (CMA) and rail kit designed for DL300 Gen10+ rack servers. At 22.00 x 5.00 x 1.70 inches and 2.25 lb, it fits cleanly into a standard 1U rack slot and routes rear-panel cabling so power, data, and management cables stay organized as the server slides in and out on its rails — eliminating the cable stress and tangling that makes maintenance on dense rack deployments time-consuming and error-prone.

Compatibility

Designed specifically for the HPE ProLiant DL300 Gen10+ server family in 1U rack configurations. Verify your specific DL300 Gen10+ model against HPE's compatibility matrix before ordering — not all DL300 variants use the same rail and CMA attachment points. This kit is not interchangeable with Gen9 or Gen10 (non-Plus) rail systems.

Installation Notes

Form factor is 1U rack; confirm your rack cabinet has sufficient rear clearance for the CMA swing radius before installation. The kit measures 22.00 inches in length, which sets the minimum usable rack depth. Country of manufacture includes CZ, JP, MX, SG, and TW — standard for HPE rack accessories sourced through global supply.
