You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product. 1. Align the tabs on the cooling shroud with the slots on the chassis. 2. Lower the cooling shroud into the system until the tabs seat securely on the slots on the blade chassis. 3. Close the blade. 4. Install the blade in the enclosure. Hard Drives/SSDs • The system supports up to four 2.5 inch SAS hard drives or two PCIe SSDs. • All drives connect to the system board through the SSD/SAS hard-drive backplane. • Hard drives/PCIe SSDs are supplied in special hot-swappable drive carriers that fit in the drive slots. • All empty drive slots must have hard-drive blanks installed.
