17.1 Maintenance Precautions
Note the following points when you maintain the CMU.
Caution - The CMUU weighs 10 kg (22 lb), and the CMUL weighs 13 kg (29 lb). Work must be done by two people if the server 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 server.
  1. If you have replaced the CMUL that has the hardware RAID function enabled, re-enable the hardware RAID volume. For details, see "14.2.11 Re-enabling a Hardware RAID Volume" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 System Operation and Administration Guide.
  2. When you add or remove a CMUU, a root complex is also added or removed. As a result, the PCIe card installation rules and the physical device paths may change, making it necessary to reconfigure the logical domains. For details, see "7.2 Precautions for FRU Expansion" or "7.3 Precautions for FRU Reduction."
