IBM xSeries 336 Type 8837: User's Guide
To start the Enhanced Diagnostics diagnostic programs, press F2 while the
server is starting.
The baseboard management controller (BMC) is a service processor that
provides environmental monitoring for the server. If environmental conditions
exceed thresholds or if system components fail, the baseboard management
controller lights LEDs to help you diagnose the problem. Critical errors are also
included in the error log.
IBM Director is a workgroup-hardware-management tool that you can use to
centrally manage xSeries servers. For more information, see the IBM Director
documentation on the IBM Director CD.
IBM X-Architecture technology combines proven, innovative IBM designs to make
your Intel-processor-based server powerful, scalable, and reliable. For more

– Active Memory
The Active Memory feature improves the reliability of memory through memory
mirroring, and online-spare memory. Memory mirroring stores data in two
pairs of DIMMs simultaneously. Online-spare memory disables a failed pair of
DIMMs from the system configuration and activates a pair of online-spare
DIMMs. For more information, see the section about installing DIMMs in the
IBM xSeries 336 Type 8837 Installation Guide.
– Large system-memory capacity
The memory bus supports up to 16 GB of system memory. The memory
controller supports error correcting code (ECC) for up to eight
industry-standard PC3200, 400 MHz, 1.8 V, 184-pin, registered,
double-data-rate (DDR), synchronous dynamic random access memory
(SDRAM) dual inline memory modules (DIMMs).
– Memory ProteXion
The Memory ProteXion feature provides a function that is similar to a
hot-spare drive in a RAID array. It is based in the memory controller, and it
enables the server to sense when a chip on a DIMM has failed and to route
the data around the failed chip.
™
Setup and Installation CD
The ServerGuide Setup and Installation CD that comes with the server provides
programs to help you set up the server and install a 32-bit Windows
system. The ServerGuide program detects installed hardware options and
provides the correct configuration programs and device drivers. For more
information about the ServerGuide Setup and Installation CD, see "Using the
ServerGuide Setup and Installation CD" on page 21.
