Intel® Server Board S2600CP and Server System P4000CP TPS Intel® Server System P4000CP Storage and Peripheral Drive Bays There are several connectors on the backside of each backplane. The following illustration identifies each of them: Label A B C D Description I2C-Out cable connector for multi-backplane support 4-port Mini-SAS cable connectors I2C-In cable connector (From Server board or other backplane) Power connector Figure 41. 2.5" Backplane, Back Side A, C - I2C Cable Connectors - The backplane includes two cable connectors used as a management interface between the server board and the installed backplanes. In systems configured with multiple backplanes, a short jumper cable is attached between backplanes, with connector B used on the first board and connector D used on the second board, extending the manageability to each installed backplane. B - Multi-port Mini-SAS Cable Connectors - The backplane includes two multi-port mini-SAS cable connectors, each providing I/O signals for four SAS/SATA hard drives on the backplane. Cables can be routed from matching connectors on the server board, add-in SAS/SATA RAID cards, or optionally installed SAS expander cards. D - Power Harness Connector - The backplane includes a 2x2 connector supplying power to the backplane. Power is routed to each installed backplane by a multi-connector power cable harness from the server board. Note: The two SATA 6G connectors from ACHI (white connectors) on server board are not recommended to connect to the 8X2.5 backplane. The LED indicators on the front side of the 8X2.5" drive bay will not light up if used as such. 11.1.2 Cypress* CY8C22545 Enclosure Management Controller The backplanes support enclosure management using a Cypress* CY8C22545 Programmable System-on-Chip (PSoC*) device. The CY8C22545 drives the hard drive activity/fault LED, hard drive present signal, and controls hard drive power-up during system power-on. Revision 1.2 115 Intel order number G26942-003
