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.

7026 Model 6M1 CEC Drawer
The RS/6000 Enterprise Server Model M80 and Eserver pSeries 660 Model 6M1 systems are
multiprocessor, multibus systems packaged in two to five drawers. The processors and memory are
packaged in an 8 EIA-unit central electronics complex (CEC) drawer, and the optional DASD and I/O
devices are in 5 EIA-unit I/O drawers. The basic system consists of one CEC drawer and one I/O drawer
in the same rack. The system is expanded by adding up to three additional I/O drawers in a minimum of
two racks. For technical information on the I/O Drawer see “I/O Drawer 5 EIA” on page 79.
