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.
