Release levers Release button Notes: v In a BladeCenter unit that supports multiple types of power modules with different capacities, such as the BladeCenter Type 8677, the maximum number of blade servers that the BladeCenter unit supports varies by the wattage of the power modules that are installed in the BladeCenter unit. For more information about determining the power requirements for the blade server, see the IBM Eserver BladeCenter Power Module Upgrade Guidelines Technical Update on the World Wide Web at http://www.ibm.com/support/. v Two power modules are required to support the blade servers in power domain A in the BladeCenter unit. The following blade bays are in power domain A: - Blade bays 1 through 6 in a BladeCenter Type 8677 or similar unit - Blade bays 1 through 5 in a BladeCenter T unit If you install blade servers in these blade bays, you must install power modules in power-module bays 1 and 2 in the BladeCenter unit. v Two additional power modules are required to support the blade servers in power domain B in the BladeCenter unit. The following blade bays are in power domain B: - Blade bays 7 through 14 in a Type 8677 or similar BladeCenter unit - Blade bays 6 through 8 in a BladeCenter T unit If you install blade servers in these blade bays, you must install power modules in power-module bays 3 and 4 in the BladeCenter unit. v Make sure that you review and understand the design of the BladeCenter unit. Use this information to help you determine your system configuration requirements and the bays and connectors where you will install or remove 2 BladeCenter JS20 Type 8842: Hardware Maintenance Manual and Troubleshooting Guide
