7.3 Hot-Swap Backplane Board Layout
The backplanes reside in the hot-swap drive bay of the Intel
LB440GX 2U rack server chassis. Note
this is a passive backplane, which means there is no firmware associated with it (no SAF-TE ASIC).
As a result, server management will not be able to determine the status of each drive.
The following diagram shows the layout of components and connectors on the hot-swap SCSI
backplane printed circuit board.
