BladeCenter JS20 Type 8842: Installation and User's Guide
IBM Director is a workgroup-hardware-management tool that you can use to
centrally manage servers. For more information, see the IBM Director
documentation on the IBM Director CD.

970 microarchitecture
IBM PowerPC 970 microarchitecture technology leverages proven innovative IBM
technologies to build powerful, scalable, reliable IBM-processor-based servers.
PowerPC 970 microarchitecture technology includes features such as light path
diagnostics, Predictive Failure Analysis (PFA), and Advanced System
1
Management.
Your blade server supports two IBM PowerPC 970 microprocessors and comes
with two microprocessors installed. Together, these two microprocessors enhance
performance. With two microprocessors, your blade server can operate as a
symmetric multiprocessing (SMP) server. With SMP, certain operating systems
and application programs can distribute the processing load between the
microprocessors. To use SMP, obtain an SMP-capable operating system. For a
list of supported operating systems and other options, go to
http://www.ibm.com/servers/eserver/serverproven/compat/us/.
Your blade server comes with one integrated dual-port Gigabit Ethernet controller.
Each Ethernet controller port has an interface for connecting to
10/100/1000-Mbps networks through an Ethernet-compatible switch module on
the BladeCenter unit. The switch module automatically selects between
10BASE-T and 100/1000BASE-TX environments. Each controller port provides
full-duplex (FDX) capability, which enables simultaneous transmission and
reception of data on the Ethernet local area network (LAN). The controller
supports Wake on LAN
Your blade server comes with two connectors on the system board for an
optional I/O expansion card for adding more network communication capabilities
to the blade server.
The memory controller provides support for up to four industry-standard 2.5 V,
184-pin, double-data-rate (DDR), PC2700, registered synchronous dynamic
random-access memory (SDRAM) with error correcting code (ECC) dual inline
memory modules (DIMMs). For the most current list of supported DIMMs, see the
®
ServerProven list at http://www.ibm.com/servers/eserver/serverproven/compat/
us/. For more information, see "Installing memory modules" on page 24.
The light path diagnostics feature provides light-emitting diodes (LEDs) to assist
in isolating problems with the blade server. An LED on the blade-server control
panel is lit if an unusual condition or a problem occurs. If this happens, you can
look at the LEDs on the system board to locate the source of the problem. For
more information, see "Light path diagnostics overview" on page 80.
