Maintenance of a proper service clearance should allow proper air flow.
Service (See service clearances for the 7014 Series Model T00 Rack )
1. See “Noise Emission Notes” on page 336 for definitions of noise emissions positions.
2. Noise emissions data are based on the following configuration: the drawer is mounted in a 7014 Series Model
T00 Rack , a power distribution unit is installed in the rack, and the system is operating in a normal environment
of 25 °C (78 °F).
3. Inrush currents occur only at initial application of power; no inrush occurs during normal power off-on cycle.
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.
