Emergency flash
10.4 Emergency flash
If the iRMC S2/S3 firmware can no longer be executed, e.g. because the SDRs
are not compatible with the system, then you can use the emergency mode to
start the firmware running again. In emergency mode, the system automatically
branches to the bootloader and is the ready for the firmware update.
I
Emergency mode is indicated by the error LED (global error LED) (rot)
and the identification LED (blue) flashing alternately.
To switch the managed server to emergency mode and then update the
iRMC S2/S3's firmware, proceed as follows:
Ê Disconnect the power supply connector.
Ê Insert the connector in the socket again with the Identify key held down.
The managed server is now in emergency mode.
Ê Boot the server to DOS and use the recovery flash procedure to update the
iRMC S2/S3’s firmware.
I
If the firmware is not active then the boot operation may take up to 2
minutes to start. You can ignore the error message “iRMC S2/S3
Controller Error” which the BIOS outputs during this period.
