1. Inrush currents occur only at initial application of power, no inrush occurs during normal power off-on cycle.
2. For altitudes above 915 meters, the maximum temperature limit is derated by 1 degree C for every 137 meters of
elevation above 915 meters.
3. See “Noise Emission Notes” on page 336 for definitions of noise emissions positions.
4. For systems with FC 6120: 80/160 GB Internal Tape Drive with VXA Technology or FC 6134: 60/150 GB 16-bit
8mm Internal Tape Drive, the maximum operating temperature is limited. For additional information about this
limitation, refer to the following table.
The following table lists maximum operating temperatures for system features at various altitudes.
