Power modules

The BladeCenter H supports up to four hot-swap redundant 2980 W AC power modules. Power module

redundancy is provided within a pair (power modules 1 and 2; power modules 3 and 4). Older models might

contain 2900 W power modules. To determine whether you need 2980 W power supplies, consult the

"Supported servers" section.

The power modules in bays 1 and 2 are used to power blade servers in blade bays 1 - 7 and I/O modules in I/O

module bays 1 - 4 and 7 - 10. The power modules are needed in power module bays 3 and 4 if you install blade

servers in blade bays 8 - 14, or if you install I/O modules in any of I/O module bays 5 - 10.

Two power modules are standard in model 5Tx, and a maximum of four power modules are supported. Models

93x, 94x, and 95x come standard with four power supplies. Table 11 shows the ordering information for power

modules (the part number contains two power modules).

96x, and some older models (4Tx, 91x, 92x, 93x). Optional in other older BladeCenter H models.

To determine whether you need Enhanced Cooling modules, consult the "Supported servers" section.

Table 13 lists the optional enhanced blowers that can be ordered for the BladeCenter H chassis (the part
