About this part
Refurbished Dell 3U sliding rail kit for the Dell 14th gen PowerEdge R940 four-socket server, the ReadyRails sliding kit sold under rail identifier B12. Dell matches rails to servers by rail identifier, so the A or B code is what has to fit your chassis, not the server name. Sliding rails pull the server out of the rack for service, while static rails fit more rack types but hold the chassis in place.

Compatibility
The R940 is a 3U chassis and takes its own rail; the 2U and 4U ReadyRails II kits do not fit it. This kit is the sliding version, which installs tool-less in square-hole and unthreaded round-hole 4-post racks and extends the server forward for service. Rack depth matters on a 3U four-socket chassis with a CMA fitted, so measure from the front mounting flange to the rear door before ordering the arm.

When to Choose This
Choose this kit when the R940 will be opened in place: four sockets, 48 DIMM slots and the riser cage all want a service slide. Dell does not sell a static alternative for this chassis, so the only other route is a third-party shelf. Fair warning: resellers attach the B12 identifier to several Dell part numbers; match the identifier stamped on your existing rail, and if the rack is threaded, confirm the adapter requirement before the install day.
