It is advised to always use staged Update Mode as it provides automatic recovery to
operational IPMC code in case of upgrade failure.
See
more details firmware update modes and the procedure for updating IPMC firmware.
Ejector Mechanism
In addition to captive retaining screws, the MPCBL0050 SBC has two ejector
mechanisms to provide a positive cam action, which ensures that the blade is properly
seated and helps assist during blade extraction. The bottom ejector handle also has a
micro switch that is connected to the IPMC to determine if the board has been properly
inserted.
Hot Swap LED
The MPCBL0050 SBC supports one blue Hot Swap LED, mounted on the front panel.

from the chassis. The on-board IPMC drives this LED to indicate the Hot Swap state.
See
When the lower ejector handle is disengaged from the faceplate, the Hot Swap switch
on the board asserts a signal to the IPMC, and the IPMC moves from the M4 state to
the M5 state. At the M5 state, the IPMC asks the CMM (or Shelf Manager) for
permission to move to the M6 state. The Hot Swap LED indicates this state by blinking
on for about 100 milliseconds, followed by 900 milliseconds in the off state. This occurs
as long as the SBC remains in the M5 state. Once permission is received from the CMM
or higher level software, the SBC moves to the M6 state.
The CMM or higher level system software may be configured to reject the request to
move to the M6 state. If this occurs, the Hot Swap LED returns to a solid off condition,
indicating that the SBC has returned to M4 state.
If the SBC reaches the M6 state, either through an extraction request through the
lower ejector handle or a direct command from higher-level software, and an a ACPI-
enabled OS is loaded on the SBC, the IPMC communicates to the OS that the module
must discontinue operation in preparation for removal. The Hot Swap LED continues to
flash during this preparation time, just like it does in the M5 state. When the main
board power is successfully removed from the SBC, the Hot Swap LED remains lit,
indicating it is safe to remove the SBC from the chassis.
Removing the SBC prematurely can lead to corruption of files on the hard drive.
• Staged Update Mode – The Staged Update feature allows the IPMC operational
MPCBL0050 Single Board Computer
code to be updated while the system is online (OS is running). After the new image
has been staged, it is copied to the internal flash of the IPMC upon completion of
the staged upgrade. If the switchover fails, or at the user’s discretion, the firmware
may be rolled back to the previous version.
The advantage of running this mode are is the user can store the old firmware
image to a rollback region (for redundancy or backup purposes).
