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.

Table 12 on page 46

, describes the:

Connections to base and fabric interfaces on the MPCBL0001 board for E-keying purposes.

Link descriptor list for the two Gigabit Ethernet channels connected to the base interface and
the two Fibre Channels on the fabric interface.

NOTE:

Fibre Channel E-keying is only applicable to MPCBL0001FXX products.

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.
