Operational vibration depends on the type of chassis in the cabinet. The operational vibration limit for a typical node is 0.26G (rms) at 10-500 Hz. The operational vibration limit for a typical disk chassis is 0.28G (rms) at 5-500 Hz.
|Static discharge limit||4000 V direct discharge, 8000 V air discharge||N/A||N/A|
a Operating temperature and moisture level is measured at individual chassis inlet.
b Due to lower air density at higher altitudes, the maximum dry bulb operating temperature is derated linearly by a value of 3.3° C per 1000 m (1.8° F per 1000 ft) between the altitude of 900 m (2952 ft) and 3050 m (10,000 ft).
c The allowable environmental envelope is a statement of functionality of the equipment. The recommended environmental envelope is a statement of reliability—operating equipment near the allowable limits for long periods of time could result in increased reliability issues.
