Important Notes
• It is recommended not to downgrade CMC or Mainboard rmware below the supported versions mentioned in this Release notes, since
previous versions of CMC and Mainboard do not support SPERC disable option.
• When the second SPERC is in the disabled mode, if a CMC with rmware version 1.30 or 1.31 is inserted into the chassis, then update
the CMC rmware to 1.35 and run the options to disable the PERC again.
• The shared hard disk drives (HDDs) and the PCIe cards are managed by the CMC and are not visible to the operating system in the
server modules, until the HDDs and PCIe cards are mapped by using the CMC web interface. For instructions about mapping PCIe
cards and managing the Storage subsystem, see the Chassis Management Controller for PowerEdge VRTX User's Guide available at
the support site.
• All the server modules must be turned o before updating the rmware for chassis infrastructure and SPERC. CMC rmware can be
updated while the servers are turned on.
• Some advanced features require CMC enterprise license. For more information about the CMC licenses, see the Chassis Management
Controller for PowerEdge VRTX Version User's Guide available at the support site.
• Before updating the Storage component using the web interface, make sure that the browser’s Cookies are enabled.
