Removing and installing power modules

The BladeCenter T unit is separated into two power domains. To support devices in

power domain B, a power-supply module option (consisting of two power modules)

must be installed.

The following table summarizes the modules that are powered by each power

domain.

Power domain Power-module bays Modules powered by the power domain

A 1 and 2 I/O-module bays 1 and 2

Management-module bays 1 and 2

Media tray

Blade bays 1 through 4

B 3 and 4 Blade bays 5 through 8

I/O-module bays 3 and 4

All four blowers are required for redundant system operation. Power for all four

blowers is shared by all installed power modules. One failed blower creates a

nonredundant configuration.

If a power module fails or an input power failure occurs, BladeCenter T units that

are configured for redundant power operation will operate in a nonredundant mode.

You must replace the failing power module or restore input power as soon as

possible to regain redundant power operation.

Important:

1. The power modules must be installed in pairs in a domain and must match each

other in capacity (wattage, amperage, and so on).

2. To provide true redundant power, BladeCenter T power modules 1 and 3 must

be connected to a different input power source than power modules 2 and 4.
