Intel SERVER CHASSIS SR2500 SR2500 Manual De Usuario

Intel® Server System SR2500AL 

The chassis incorporates several design changes from the previous generation Intel 2U server 
chassis, resulting in improved cable routing.  System boards within the chassis include the mid-
plane, bridge board, hot-swap backplane, and control panel.  This chapter describes the 
interconnect features of each, and defines the pin-outs for each of their connectors. Functional 
details of each system board are described in later chapters. 

The mid-plane is new to this generation of Intel high density server platforms.  Its design and 
use, along with that of the bridgeboard and hot-swap backplane, improve cable routing within 
the system. The mid-plane is the key system board of the chassis.  It serves as the primary 
interface between the server board, hot-swap backplane, and control panel. Two mid-planes are 
offered for this chassis: 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 baseboard or SAS/SATA connectors on an add-in card. 

The following diagram shows the location for each connector found on the passive mid-plane 
board.
