The Application layer also can operate in standalone mode intended to debug the payload
without requiring a shelf manager.

HPM.1 Firmware Upgrade and Crisis Recovery
The IPMI firmware of the IPMC and MMC is fully HPM.1 compliant. Both IPMI controllers provide
three components:
z
Boot Loader
z
Active IPMI firmware
z
Backup IPMI firmware
The boot loader maintains redundant copies of the firmware in flash. Each time the IPMI
firmware is upgraded, a redundant copy of the current IPMI firmware is made in flash. Once the
new IPMI firmware is programmed, the IPMI controller will reset itself to boot from the new
image. The boot loader also validates new IPMI firmware images. Provided the IPMI controller
can power up successfully the actual image is made active and the previously active image is
made backup. In case of power up fails, the boot loader will automatically recover from crisis
and boots from the image before.
