2.21Running Your System Without A CMM

In CMM-based systems, the CMM controls power to the general-purpose slots in accordance with the PICMG* 2.1 specification. PICMG* 2.1 defines the power control signals (BD_SEL#) as pulled up on general-purpose boards. When the BD_SEL# signals are not asserted (grounded) by external means, the general-purpose boards will not power up. Therefore, to operate a CMM-based system without a CMM board, BD_SEL# must be grounded at each slot on the backplane.

Your system may have jumpers at each slot on the backplane to ground BD_SEL#. Inserting the BD_SEL# jumper will allow the node slot to power up regardless of the CMM. Node slots with the BD_SEL# jumper installed cannot be managed using the CMM. Refer to system-specific documentation for more information about running the system with or without a CMM board.
