Installing a module, Blower modules | IBM 8677 specification

Each pair of power modules is redundant. If either power module fails, the remaining power module continues to supply power, but there is no redundancy; the failed power module must be replaced as soon as possible.

Important:

1.The power modules in a pair must match each other in capacity (wattage, amperage, and so forth).

2.In a pair of power modules, a power module that is not connected to an ac power source creates a non-redundant condition.

To provide true redundant power, BladeCenter power modules 1 and 3 must connect to a different ac power source than power modules 2 and 4. Connect BladeCenter power modules 1 and 3 to a different PDU than power modules 2 and 4; then, connect each PDU to an ac power source (building power source or service entrance) that is controlled by a separate circuit breaker.

Blower modules

Your BladeCenter unit comes with two hot-swap blowers for cooling redundancy. The blower speeds vary depending on the ambient air temperature at the front of the BladeCenter. If the ambient temperature is 72°F or below, the BladeCenter blowers will run at 30% of their maximum rotational speed, increasing their speed as required to control internal BladeCenter temperature. If the ambient temperature is above 72°F, the blowers will run at 80% of their maximum rotational speed, increasing their speed as required to control internal BladeCenter temperature. If a blower fails, the remaining blower continues to cool the BladeCenter unit and blade servers.

Important: Replace a failed blower as soon as possible, to restore cooling redundancy (see the Hardware Maintenance Manual and Troubleshooting Guide on the BladeCenter Documentation CD for instructions).

Installing a module

The following illustration shows how to install a power module, management module, or I/O module in the rear of the BladeCenter unit. See the Hardware Maintenance Manual and Troubleshooting Guide on the BladeCenter Documentation CD for information about replacing a blower module.

Before you begin, read the documentation that comes with your option.
