3.5 Inch LFF Hot Swap Hard Drive Tray Caddy P/N X7K8W 0X7K8W, SAS SATA HDD SSD Carrier Bracket for Dell PowerEdge 14th/15th/16th Gen R7415 R740 R640 R540 R440 R750 R650 R550 R450 R760 R7615 R660

This 3.5-inch large form factor hot swap hard drive caddy is a direct OEM replacement with part number X7K8W (alternative code 0X7K8W), engineered to match Dell 14th, 15th and 16th generation server hard disk bays without chassis modification.

It perfectly fits mainstream Dell rack server models covering three generations: 14G R7415, R740, R640, R540, R440; 15G R750, R650, R550, R450; 16G R760, R7615, R660. The tray supports all standard 3.5-inch SATA and SAS mechanical hard disks and enterprise SSDs, and can pair with matched 2.5-inch adapter brackets to realize mixed SFF/LFF storage deployment.

Constructed with thickened steel structure, the carrier adopts hollow airflow design to accelerate heat dissipation and avoid thermal throttling under heavy continuous I/O loads. Anti-vibration rubber cushions reduce operational vibration to protect hard disk hardware and guarantee data integrity for round-the-clock data center operation.

Hot swap function allows IT technicians to remove or replace faulty storage drives without shutting down the whole server, greatly cutting maintenance downtime for enterprise business. Dual front panel LED lights offer intuitive visual monitoring of disk running state, enabling fast fault inspection without accessing server management software.

The tray is fully plug-and-play with Dell PERC RAID controllers, no firmware upgrade required after installation. Matched mounting screws are included to lock hard drives firmly inside the sled and prevent loose contact during equipment transport or long-term running.

Ideal for server storage capacity expansion, defective hard disk replacement, mixed SSD/HDD layout and cross-generation Dell server hardware renovation.
