Info

Attention: Nonredundant power is not supported in BladeCenter products. Power modules must always be present in power bays 1 and 2. When any blade server or option is in blade bays 7 through 14, power modules must be present in all four power-module bays. If a power module fails or an ac power failure occurs, BladeCenter units configured for redundant power operation operate in a nonredundant mode, and the blower modules runs at full speed. You must replace the failing power module or restore ac power as soon as possible to regain redundant power operation and to reset the blower modules to their normal operating speed. As of the date of this publication, these four BladeCenter power-module options are supported: ► IBM BladeCenter 1200W Power Supply Module (part number 48P7052) ► IBM BladeCenter 1200W to 1400W Power Supply Upgrade Kit (part number 90P0197) ► IBM BladeCenter 1800W Power Supply Module (part number 13N0570) ► IBM BladeCenter 2000W Power Supply Module (part number 26K4816) Not visible in either view of the BladeCenter chassis are the redundant pair of midplanes in the center of the BladeCenter chassis that interconnect the blade servers installed in the front, and other modules that are installed in the rear of the BladeCenter chassis. The midplanes support the hot-plugging of blade servers and the other BladeCenter modules. Note: IBM offers a variant of the BladeCenter called the BladeCenter T. The BladeCenter T is designed to meet the special needs of the telecommunications industry and has been tested for NEBS compliance. Since BladeCenter JS20 is not supported in the BladeCenter T at this time, we do not describe BladeCenter T and its associated features in this book. 2.1.2 BladeCenter power options The standard redundant power supplies are installed in power bays 1 and 2 of the BladeCenter chassis, and provide power to the first six blade server bays. This is known as power domain A. To install blade servers in the remaining bays 7 through 14, you must install an additional pair of redundant power supply modules in power bays 3 and 4. This is known as power domain B. Figure 2-3 shows these two power domains. 10 The IBM Eserver BladeCenter JS20
