to be installed during initial installation, or as a later update. To determine the power and
air-conditioning that is required, see the applicable documentation for such devices.
Acoustic Noise Specification
The acoustic noise specification for the HP Integrity rx8620 Server is 55.6 db (sound pressure
level at bystander position). It is appropriate for dedicated computer room environments, not
office environments. The LwA is 7.4 Bels. Care should be taken to understand the acoustic noise
specifications relative to operator positions within the computer room or when adding servers
to computer rooms with existing noise sources.
