Note: The power management policy that you have implemented for theBladeCenter S system determines the result of a power module failure.Power modules also provide cooling fans for the disk storage modules.Therefore, if you are using disk storage module 1, you must install powermodules 1 and 2. If you are using disk storage module 2, you must installpower modules 3 and 4.– Fan modules. In normal operation, fan modules share the cooling in theBladeCenter S system. If one fan module fails, the other three fan moduleshandle the entire load. You can replace a fan module without shutting downthe BladeCenter S system.– BladeCenter S system midplane. The midplane has the followingcharacteristics:- Redundant high-speed serialize/deserialize (SERDES) interconnectsbetween blade servers and switches- I2C communication between the advanced management module and allmodules (except blade servers)- RS-485 (EIA 485) communication between the advanced managementmodule and blade servers- Analog video connectors from the blade servers to the advancedmanagement module- USB connections between the blade servers and the advanced managementmodule– Redundant storage access. Installing a pair of SAS connectivity modules orSAS RAID controller modules in I/O module bays 3 and 4 provides supportfor redundant access to the disk storage modules in the BladeCenter S chassis(if both disk storage modules are installed).v Systems managementThe advanced management module is used to communicate with the serviceprocessor in each blade server to provide system monitoring, event recording,and alerts. You can manage the BladeCenter S chassis, its devices, and the bladeservers remotely.Related documentationIn addition to this document, the following related documentation is provided inPortable Document Format (PDF) on the IBM BladeCenter Documentation CD thatcomes with your BladeCenter S chassis.Note: The latest and most up-to-date product information for the BladeCenter STypes 7779 and 8886 can be found at the IBM Systems Information Center, whichis at http://publib.boulder.ibm.com/infocenter/systems/index.jsp.
