Fujitsu Oracle SPARC M12-2 User Manual

Caution -
The CMUU weighs 10 kg (22 lb). Work must be done by two people if the
chassis is mounted at the 24U or higher position of the rack. If the work is done by
one person, it may result in an injury or damage to the chassis.
Caution -
Be sure to remove the XBU before removing the CMUU from the SPARC
M12-2S. Replacing the CMUU with the XBU installed may damage the CMUU or
XBU.
Caution -
Be sure to bundle PCIe cables in the specified procedure before removing
the CMUU. Removing the CMUU without bundling PCIe cables may damage those
PCIe cables. For details on the procedure, see "Chapter 17 Maintaining the CPU
Memory Unit and Memory."
unusable for expansion in the building block configuration.
■
When adding the SPARC M12-2S to a building block configuration, assign BB-IDs
in ascending order without duplication.
■
To use the added CPU resources after SPARC M12-2S addition, you need to assign
CPU Activations. Check the number of CPU Activation keys registered with the
device and the number of CPU Activations assigned to the physical partition,
before using them.
For details, see "Chapter 5 CPU Activation" in the Fujitsu
SPARC M12 and Fujitsu
M10/SPARC M10 System Operation and Administration Guide.
■
To add a SPARC M12-2S with 64 GB DIMMs mounted to a building block
configuration, see "Notes on Memory" in the latest version of the Fujitsu SPARC
M12 Product Notes.
7.3 Precautions for FRU Reduction
This section describes the precautions for FRU reduction.
Before performing reduction work, see "(3) Checking the FRU status" in "8.2.2
Identifying a Fault" to confirm that there is no problem with the chassis requiring
reduction.
Precautions for CMUU removal
■
To operate the system with the CMUU removed, mount the stored CMU filler unit
after removing the CMUU. Not using the CMU filler unit hinders chassis cooling,
resulting in unstable system operation.
■
If the CMUU in the following system or state is removed, a root complex is also
removed and some PCIe slots become unusable:
