The CMM or higher level software can 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 HP bc2100 ATCA Server Blade has returned to M4
state.
If the HP bc2100 ATCA Server Blade reaches the M6 state, either through an extraction request through the
lower ejector handle or through a direct command from higher-level software (and an ACPI-enabled OS is
loaded on the HP bc2100 ATCA Server Blade) 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 at the M5 state. When main board power is successfully removed from the
HP bc2100 ATCA Server Blade, the Hot-Swap LED remains lit, indicating it is safe to remove the HP bc2100
ATCA Server Blade from the chassis (see Table 2-31).
CAUTION Removing the HP bc2100 ATCA Server Blade prematurely can lead to device corruption or
failure.
It is possible to override the default IPMC behavior of the LED using ATCA FRU LED Control commands.
Reset Button
The reset button is located in a small recessed hole below the USB ports. The reset button is used as an input
to the IPMC to request a cold reset. There are IPMI commands to reset the board and change power states
through the software. The reset button is a last resort, since you must be physically present at the chassis to
reset the board. The reset button is located on the HP bc2100 ATCA Server Blade front panel
(seeFigure 2-17).
