A systems administrator is mounting a fully populated 10U blade chassis in a data-center rack. Which installation requirement is unique to blade enclosures and is not normally encountered when installing the same number of stand-alone 1U rack servers in that rack?
Provisioning and cabling a shared midplane/backplane that distributes power and I/O to all inserted blades
Choosing rail kits that match the rack's square-hole versus threaded-post design
Verifying that the raised-floor weight rating can support each individual server
Running an independent power cord from every server to a separate PDU circuit
Blade enclosures contain a shared midplane or backplane that delivers consolidated power, network and storage connectivity, cooling airflow, and management signalling to every server blade that is inserted. Before any blades are installed, the technician must verify that this midplane is correctly seated and that the enclosure's common power supplies, fans and interconnect modules are cabled to the appropriate power and network infrastructure. Stand-alone rack servers do not rely on a common midplane; each one is wired individually for power and I/O, so the other listed tasks-selecting rail kits for rack post types, checking floor load limits, and running separate power cords-apply equally (or even more) to traditional rack servers and therefore are not unique to blade chassis installation.
