Note - To ensure compatibility and optimal performance, You should update your server to the latest version of firmware.
Firmware resides on both the SP module and the CPU modules (CMOD). The firmware versions on both components must match. You can perform firmware updates only on the SP module. The firmware that resides on the CMODs is maintained by the SP module. The SP module automatically updates all CMODs to its version of firmware. If a CMOD is replaced and its version is different from the firmware version that resides on the SP module, then the SP module will update or downgrade the new CMOD to the version of firmware that resides on the SP module. If the SP module is replaced and its firmware is different from the firmware on the CMODs, it will update or downgrade the CMODs to the version of firmware that resides on the SP module.
The following table shows the resulting SP module response to user-initiated firmware updates and component replacements.
