Loudness

The acoustic emission values [loudness in dB(A)] for the Universal Storage
Platform VM storage system are:
• Front/rear = 65 dB(A)
• Both sides = 65 dB(A)

Vibration and Shock

Table 2-11
VM can be subjected to vibration and shock up to these limits and still
perform normally. Consider these requirements if there are large generators
located on the floor above or below the storage system. Generators or any
other source of vibration, if not insulated or shock mounted, can cause
excessive vibration that may adversely affect the storage system.
