5. System Board Interconnects
System boards within the system include the midplane, bridge board, hot-swap backplane, and
control panel. This chapter describes the interconnect features of each, and defines the pin-
outs for each connector. Functional details of each system board are described in later
chapters.
5.1 Midplane
The midplane is designed and used, along with that of the bridge board and hot-swap
backplane, to improve cable routing within the system. The midplane is the key system board of
the system. It serves as the primary interface between the server board, hot-swap backplane,
and control panel. Two midplanes are offered for this system: a passive SATA/SAS, and an
active SAS/SAS RAID.
The passive midplane is a simple pass-through from the backplane to the SATA connectors on
the server board or SAS/SATA connectors on an add-in card.
The following figure shows the location for each connector found on the passive
midplane board.
