36 Technical Product Specification
Caution: The ZT 7102 contains a lithium battery. Do not disassemble or recharge the battery. Do not dispose
of the battery in fire. When the battery is replaced, the same type or an equivalent type
recommended by the manufacturer must be used. Used batteries must be disposed of according to
the manufacturer's instructions.
2.21 Running 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.
