2.3.1 Operatinq Environment
The disk dr i ve can be installed in any clean, rela tively
dust-free environment with an ambient temperature of 50 ° F
to 113°F (10°C to 45°C) and relative humidity of 20% to 80%.
The maximum stray magnetic field is 4000 Amperes per meter
(Aim) •
Typical hea t diss ipation is 22.3 Ki logram Calor ies
per Hour (Kcal/h) (23.3 Kcal/h with VFO).
2.3.2 Space and Weight Data
The unit should be mounted to provide space for cabling and
servicing. Refer to Figure 2-2 for the physical dimensions
of the disk drive. The unit weighs 7.7 pounds (3.5 kg).
2.3.3 Mounting
The disk drive can be mounted vertically, horizontally, or
on-end. See Figures 2-3, 2-4, and 2-5 for recommended
