Each of these two additional I/O modules provides one internal connection to the optional I/O expansion card, up to 14 internal connections per I/O module.

Reliability, availability, and serviceability

Three of the most important features in server design are reliability, availability, and serviceability (RAS). These factors help to ensure the integrity of the data stored on your blade server; that your blade server is available when you want to use it; and that should a failure occur, you can easily diagnose and repair the failure with minimal inconvenience.

The following is a list of some of the RAS features that your BladeCenter unit supports:

vShared key components, such as power, cooling, and I/O

vAll components serviced from the front or rear of the chassis

vAutomatic error retry and recovery

vAutomatic restart after a power failure

vBuilt-in monitoring for blower, power, temperature, and voltage

vBuilt-in monitoring for module redundancy

vCustomer support center 24 hours a day, 7 days a week2

vError codes and messages

vFault-resistant startup

vRemote system management through the management module

vRemote management module firmware upgrade

vRemote upgrade of blade server service processor microcode

vBuilt-in self-test (BIST)

vPredictive Failure Analysis (PFA) alerts

vRedundant components

Cooling fans (blowers) with speed-sensing capability

Power modules

Management modules

vHot-swap components

Cooling fans (blowers) with speed-sensing capability
