Note 1-2: PCI Board Other Than a CLK Board or a CS1 Board Installed
The internal temperature of the PCI Board will rise 10°C at slot 1 and 15°C at slot 2. This may
place the ambient operating temperature at the high end of the range given in *1-1 above.
Therefore, set the ambient operating temperature according to the ambient operating
temperature of the PCI Board that is installed. Check prior to actual use to make sure the PCI
Board will operate properly at the selected ambient operating temperature.
Example: If a PCI Board with an ambient operating temperature of 0 to 45°C will be installed in
slot 1 with the Unit installed at angle greater than 45° and less than 75° off horizontal,
then the ambient operating temperature selected should be 0 to 35°C because of the
10°C rise in the internal temperature of the Board at slot 1.
