Figure 3 Placement of the Service Processor
NOTE: In the T800, the SP is located above the backplane, below the lowest drive chassis but
above the upper battery tray. Figure 5 (page 12) illustrates SP placement for the T800.
When a cabinet does not include a SP, a filler panel covers the area of the cabinet that the SP
normally occupies.
Understanding Component Numbering
Because of the large number of potential configurations, we have standardized component
placement and internal cabling to simplify installation and maintenance. For this reason, system
components are placed in the cabinet according to the principles outlined in this section and
numbered according to their order and location in the cabinet.
NOTE: For information about standardized cabling, see the HP 3PAR T-Class Storage System
Installation and Deinstallation Guide.
Cabinet Numbering
The T-Class Storage System 2M (40U) cabinet is an EIA-standard rack that accepts storage system
components. Numbers for chassis bays are assigned:
• beginning with 0.
• from top to bottom.
Figure 4 (page 11) illustrates numbering of chassis bays in T-Class cabinet.
