If you remove a simplexed PCI adapter, or if it fails, communications for applications related to that adapter will terminate. Removing one of two duplexed PCI adapters, however, will not affect communications. To increase the fault tolerance of a system, always install PCI adapters for critical applications in paired slots, and ensure that the adapters are marked as duplexed in ftSMC.

Duplex and simplex mode are also indicated on the PCI slot status LEDs that are located at the rear of each system. Furthermore, because PCI slot status can affect other subsystems, a missing or broken PCI adapter might change ftSMC properties and LED states for an I/O enclosure as well as an entire system.

For more information about using ftSMC to determine whether your PCI adapters or I/O enclosures are operating in duplex mode, see the Express5800/320Ma: System Administrator’s Guide. For information about using status LEDs to determine the PCI slot status, see the operation and maintenance guide for your system, as listed in Table 1-2.
