Installation Requirements
PPC/CPCI-690 2 - 5
Requirements
To meet the environmental requirements, the board has to be tested in the
system where it is to be installed. Before you power up the board, calculate
the power needed according to your combination of board upgrades and
accessories.
Environmental Requirements
The environmental values must be tested and proven in the used system
configuration. The conditions listed below refer to the surroundings of the
board within the user environment.
Note:
• Operating temperatures refer to the temperature of the air circulating
around the board and not to the component temperature.
• In order to meet the operating conditions, forced air cooling is
required at both sides of the board.
• The environmental values given in the table below only apply to the
board without any accessories. If installing accessories, their environ-
mental requirements must also be taken into account. If you use the
board together with an PMC-243D or PMC-245FD, make sure the
environmental values given in the Hardware Reference Manual
PMC233/4/5 & PMC243/4/5 High Capacity Disk Solutions are met.

pletely dry and there is no moisture on any surface before applying
