monitoring, and alerting function. If an environmental condition exceeds a
threshold or if a system component fails, the IMM lights LEDs to help you
diagnose the problem, records the error in the IMM event log, and alerts you to
the problem. Optionally, the IMM also provides a virtual presence capability for
remote server management capabilities. The IMM provides remote server
management through the following industry-standard interfaces:
– Intelligent Platform Management Interface (IPMI) version 2.0
– Simple Network Management Protocol (SNMP) version 3.0
– Common Information Model (CIM)
– Web browser
For additional information, see "Using the integrated management module" on
page 33 and the Integrated Management Module II User's Guide at the
http://www.ibm.com/supportportal.
v Large system-memory capacity
The compute node supports up to 128 GB of system memory. The memory
controller provides support for up to 8 industry-standard registered ECC DDR3
on low-profile (LP) DIMMs on the system board. For the most current list of
supported DIMMs, see http://www.ibm.com/systems/info/x86servers/
serverproven/compat/us.
v Light path diagnostics
Light path diagnostics provides LEDs to help you diagnose problems. For more
information about light path diagnostics and the LEDs, see "Compute node
controls, connectors, and LEDs" on page 13.
v Microprocessor technology
The compute node supports up to two multi-core Intel Xeon microprocessors.
For more information about supported microprocessors and their part numbers,
see http://www.ibm.com/systems/info/x86servers/serverproven/compat/us.
Note: The optional microprocessors that IBM supports are limited by the
capacity and capability of the compute node. Any microprocessor that you
install must have the same specifications as the microprocessor that came with
the compute node.
v Mobile access to IBM Service Information website
The server provides a QR code on the system service label, which is on the
cover of the server, that you can scan using a QR code reader and scanner with
a mobile device to get quick access to the IBM Service Information website. The
IBM Service Information website provides additional information for parts
installation and replacement videos, and error codes for server support. For the
QR code, see Chapter 1, "The IBM NeXtScale nx360 M4 Compute Node Type
5455," on page 1.
v PCI Express
PCI Express is a serial interface that is used for chip-to-chip interconnect and
expansion adapter interconnect. You can add optional I/O and storage devices.
Optional expansion nodes are available to provide a cost-effective way for you
to increase and customize the capabilities of the compute node. Expansion nodes
support a wide variety of industry-standard PCI Express, network, storage, and
graphics adapters. For additional information, see .

v Power throttling
By enforcing a power policy known as power-domain oversubscription, the IBM
NeXtScale n1200 Enclosure can share the power load between twelve power
supplies to ensure sufficient power for each device in the IBM NeXtScale n1200
