Overview of PCI Adapters 1-5
N O T E
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 .
