Intel® Server Board S2600CP and Server System P4000CP TPS Intel® Server System P4000CP Storage and Peripheral Drive Bays 11.2.2 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. 11.3 SAS Expander Card Option RS2CV240 The expander card RS2CV240 is an optional accessory that can support more than eight 2.5" hard disk drives. The expander card can be mounted directly behind the drive bay assembly as shown in the following illustration. Figure 45. Internal SAS Expander Installation The following diagrams are used to help identify the mini-SAS connectors found on the SAS expander cards. Care should be taken when connecting connectors from the SAS expander to the connectors on the backplane because each connector is pre-programmed at the factory to provide specific drive identification mapping. Improper connections may provide undesirable drive mappings. Figure 46. Internal 24-Port SAS Expander Card Revision 1.2 119 Intel order number G26942-003
