Chapter 5. IBM BladeCenter HX5

5.14.3 Integrated Management Module (IMM)
The HX5 blade server includes an IMM to monitor server availability, perform predictive failure
analysis and so forth, and trigger IBM Systems Director alerts. The IMM performs the
functions of the baseboard management controller (BMC) of earlier blade servers, and adds
the features of the Remote Supervisor Adapter (RSA) in System x servers, and also remote
control and remote media.
For more information about the IMM, see the IBM white paper, Transitioning to UEFI and
IMM, which is available at the following website:
http://www.ibm.com/support/docview.wss?uid=psg1MIGR-5079769
The IMM controls the service processor LEDs and the light path diagnostics capability. The
IMM controls the LEDs, which can indicate an error and the physical location of the error. To
enable illumination of the LEDs after the blade is removed from the chassis, the LEDs have a
backup power system. The LEDs are related to DIMMs, CPUs, battery, CIOv connector,
CFFh connector, scalability, the system board, non-maskable interrupt (NMI), CPU mismatch,
and the SAS connector.
5.14.4 Video controller
The video subsystem in the HX5 supports an SVGA video display. The video subsystem is a
component of the IMM and is based on a Matrox video controller. The HX5 has 128 MB of
video memory. Table 5-27 lists the supported video resolutions.

5.14.5 Trusted Platform Module (TPM)
Trusted computing is an industry initiative that provides a combination of secure software and
secure hardware to create a trusted platform. It is a specification that increases network
security by building unique hardware IDs into computing devices. The HX5 implements TPM
Version 1.2 support.
The TPM in the HX5 is one of the three layers of the trusted computing initiative, as shown in
Table 5-28.
