Table 2-2: Power Requirements
The exact power requirements for the PmT1 and PmE1 circuit board depend upon the spe-
cific configuration of the board, including the CPU frequency and amount of memory
installed on the board. Please contact Emerson Technical Support at 1-800-327-1251 if you
have specific questions regarding the board’s power requirements.
Environmental Considerations
As with any printed circuit board, be sure that air flow to the board is adequate. Chassis con-
straints and other factors greatly affect the air flow rate. The environmental requirements
are listed in
Tab le 2 -3 .
Table 2-3: Environmental Requirements
RESET METHODS
The entire board is reset on power-up. A baseboard PCI reset causes a PORESET* of the
PmT1 and PmE1. The PCI9060ES may be programmed to initiate a software controlled hard
reset from the PCI bus.
To do a hard reset of the PmT1 and PmE1 from the local bus, clear and then set bit 16 in the
PCI9060ES register at local address C100,00EC
16
.
To do a hard reset of the PmT1 and PmE1 from the PCI bus, the same bit must be cleared
and then set in software. However, the PCI bus is little endian so this bit appears as bit 8
from the (big-endian) point of view of the MPC860P. This means that bit 8 of the register at
offset 6C
16
from the PCI base address must be cleared and then set. After this reset, the
module must be reconfigured on PCI by the baseboard.
