ProLiant DL3XX Gen11 Rail Kit

The HPE P52341-B21 is a new rail kit designed for ProLiant DL3XX Gen11 servers. It provides the hardware needed to mount a supported server securely in a standard rack enclosure. This accessory targets system builders and IT teams deploying compatible HPE platforms.

Rack mounting hardware and space

The kit fits into a rack using the supplied rails and occupies 13.3 x 93.5 x 8.2 cm of space. It frees up internal server chassis room by moving the sliding mechanism outside the unit. The 3.8 kg assembly adds minimal load to the rack structure while enabling tool-less installation.

Sustained deployment reliability

Under continuous operation the rails maintain alignment while supporting the server weight during repeated extensions for maintenance. The steel construction resists fatigue from vibration and thermal cycling inside the cabinet. No active components are present so long-term behaviour depends on mechanical tolerance alone.

Questions about this item

How far does the 93.5 cm rail depth extend into a standard rack?

The rail measures 93.5 cm (36.81 in) deep, so it requires a rack with at least that much usable post-to-post depth for the server to seat fully.

Does the 3.8 kg rail kit add noticeable vibration or airflow restriction when the server runs continuously?

At 3.8 kg the rails are rigid steel; they do not contain moving parts, so they add no vibration or fan noise and do not impede front-to-rear airflow through the chassis.

Which HPE server chassis is this P52341-B21 rail kit built to support?

It is engineered for HPE ProLiant DL3XX Gen11 rackmount servers and includes the Easy Install Rail 3 hardware for tool-less mounting.
