Dell B6 ReadyRails II 2U sliding rail kit for PowerEdge R740, R740xd, R730 and R720 servers in 19-inch four-post racks.
The Dell B6 is a ReadyRails II sliding rail kit for 2U Dell rack systems, supplied here as a refurbished pair under our SKU SD-RAIL-DELL-B6-2U. B6 is Dell's rail identifier, and the same code covers three PowerEdge generations: the 12th generation R520, R720 and R720xd, the 13th generation R530, R730 and R730xd, and the 14th generation R540, R740 and R740xd. It also fits the Compellent SC8000 storage controller and the Precision 7920 Rack workstation. Because the rails slide, the chassis can be drawn forward out of a 19-inch four-post rack, so drives, memory, fans and expansion cards can be reached without unbolting the system or disturbing the units above and below. Data centre teams and integrators in Doha buy the B6 to rack a newly sourced server, to replace a lost or damaged kit, or to keep one common spare for a mixed PowerEdge estate across Qatar.
SD-RAIL-DELL-B6-2UWill it fit my system?
Dell lists the B6 rail across three generations of 2U PowerEdge servers, which is why it is a common spare in estates that mix 12th, 13th and 14th generation hardware in the same racks. All systems below are 2U.
| Server | Generation | Note |
|---|---|---|
| PowerEdge R520 | 12th generation | 2U rack server |
| PowerEdge R720 | 12th generation | 2U rack server |
| PowerEdge R720xd | 12th generation | 2U storage-dense variant |
| PowerEdge R530 | 13th generation | 2U rack server |
| PowerEdge R730 | 13th generation | 2U rack server |
| PowerEdge R730xd | 13th generation | 2U storage-dense variant |
| PowerEdge R540 | 14th generation | 2U rack server |
| PowerEdge R740 | 14th generation | 2U rack server |
| PowerEdge R740xd | 14th generation | 2U storage-dense variant |
| Compellent SC8000 | Storage | 2U storage controller |
Specification
The B6 is a sliding kit, so the chassis extends forward for servicing while it stays supported on both rails. Static rails, by contrast, hold the system in a fixed position, and internal work usually means taking it out of the rack first.
Installation
Fit the rails to the rack before handling the chassis, making sure the left and right assemblies are on the correct sides and sit at the same U position front and rear. In square-hole and unthreaded round-hole racks the rail ends mount without tools; in threaded-hole racks, use appropriate screws and adjust the rails before fitting the system. Extend the rails, lower the chassis onto them with a second person (a populated 2U server is heavy), and slide it home until it latches. Check that the chassis draws forward and returns freely, and leave enough cable slack at the rear so it can be extended for servicing without unplugging anything.

Ask on WhatsApp sales@serverdove.comWhich servers use the Dell B6 rail kit?
The B6 ReadyRails II sliding rail is used with the Dell PowerEdge R520, R530, R540, R720, R720xd, R730, R730xd, R740 and R740xd, the Dell Compellent SC8000 and the Dell Precision 7920 Rack. All are 2U systems, and the rail is intended for 19-inch four-post racks.
Do the B6 rails fit both the R730 and the R740?
Yes. Dell lists the B6 rail for the 13th generation R730 and R730xd and the 14th generation R740 and R740xd, as well as the 12th generation R720 and R720xd. That makes the B6 a useful common spare where several generations of 2U PowerEdge servers share the same racks.
Are tools needed to install the B6 rails?
Not in square-hole or unthreaded round-hole racks, where the rails mount tool-free. Racks with threaded holes need appropriate screws and some adjustment of the rails before the chassis can be fitted.
What is the difference between sliding and static Dell rails?
Sliding rails such as the B6 let the chassis extend forward out of the rack, so drives, memory, fans and cards can be reached without removing the server. Static rails hold the chassis in a fixed position, so internal work usually means taking the system out of the rack first.
Can the B6 rails be used in a two-post rack?
The B6 kit is specified for 19-inch four-post racks. It is not intended for two-post relay racks, which do not provide the rear mounting points the sliding rails rely on to support a 2U chassis when it is extended.
How do I confirm a rail is a B6?
Dell marks its ReadyRails with a rail identifier on the rail label, and B6 is the code to look for. The specific Dell part number on the label can vary between production runs, so the B6 identifier is the reliable value to match against the system's rail requirement.

Off-lease or decommissioned enterprise hardware that we clean, test and reset in Doha. Every unit goes through POST, burn-in, memory and drive checks and a power-supply check, with firmware and BIOS returned to defaults and drives securely erased.

Why buy refurbished
Enterprise hardware, tested in Doha, at a fraction of the price of new
Every unit we sell has already proven itself in a data centre. We test it again, grade it, and back it with a warranty before it leaves our stock.
Tested before it ships
POST, burn-in, memory and power-supply checks on every unit. Anything that fails is repaired or pulled from stock, not sold.
Same performance, lower cost
A Xeon runs the same workloads whether it is new or two years old. Spend the difference on more CPUs, memory or storage.
In stock, not on order
New enterprise hardware can take weeks or months to arrive. Ours is on the shelf in Doha and delivered across Qatar within a day.
Warranty and local support
Every unit is covered. Installation, configuration and hardware support are handled by our own team in Qatar, not a call centre abroad.
