Dell PowerEdge R940XA 2U Sliding Rail Kit

This genuine Dell T4DFW sliding rail kit is built for the PowerEdge R940XA 2U server. It provides a tool-less mounting solution that fits square-hole or round-hole enterprise racks. The steel construction with an anti-corrosion finish delivers the strength and stability required in data centre environments. Ball-bearing slides allow the server to extend fully for maintenance without removal from the rack.

Who this suits and who should look elsewhere

IT teams deploying or servicing Dell PowerEdge R940XA 2U servers will find the precise fit and Ready-Rail design essential for fast, repeatable installations. Buyers who need rails for a different server model, a different form factor, or a non-Dell rackmount system cannot use this kit. It is also unsuitable for anyone requiring a fixed rail, a cable management arm, or a toolless solution for threadless racks.

Deciding specification: part number T4DFW

The part number T4DFW is the single identifier that confirms compatibility with the Dell PowerEdge R940XA 2U server. Only this OEM kit guarantees the correct rail length, hole pattern, and latch geometry for that chassis. Verifying the T4DFW marking before purchase prevents fitment errors and avoids downtime during rack builds or hardware swaps.

Questions about this item

Does the T4DFW rail kit need any lubrication or part replacement after extended use in a 2U rack?

The ball-bearing design is sealed for life and requires no lubrication; the steel rails with anti-corrosion finish are built for long-term data centre reliability without scheduled part changes.

What stops the rails from extending further when a fully loaded PowerEdge R940XA is pulled out for service?

The Ready-Rail system includes built-in stops that prevent over-extension, keeping the 2U server secure at full slide-out so components stay accessible without the chassis tipping.

How much extra heat or fan noise does the sliding rail assembly add when the server runs continuously?

The rails are passive steel with ball bearings — they generate no heat and add no audible noise, so the server’s own cooling remains the only thermal and acoustic factor.
