E-Keying
E-Keying has been defined in the PICMG 3.0 Specification to prevent board damage, prevent
misoperation, and verify fabric compatibility. The FRU data contains the board point-to-point
connectivity record as described in Section 3.7.2.3 of the PICMG 3.0 Specification.
Upon management power-on, the firmware sets the Fibre Channel ports to front panel by default.
When the board enters M3 power state, the shelf manager reads in the board point-to-point
connectivity record from FRU and determines whether the board can enable the Fibre Channel
ports to the back plane. Set/Get Port State IPMI commands defined by the PICMG 3.0
Specification are used for either granting or rejecting the E-keys.
If user Fibre Channel selection is to the front, the firmware maintains the Fibre Channel ports to the
front panel regardless of the shelf manager's granting or rejecting of E-keys for the board.

IPMC Firmware Code
IPMC firmware code is organized into boot code and operational code, both of which are stored in
a flash module. Upon an IPMC reset, the IPMC executes the boot code and performs the following:
1. Self test to verify the status of its hardware and memory.
2. Sets up the internal real-time operating system (RTOS).
3. Performs a checksum of the operational code.
Upon successful verification of the operational code checksum, the firmware will jump to the
operational code.
