Table 35 on page 109 provides the acoustical specifications for the 2077-92F, 2077-A9F and 2078-92F,
2078-A9F SAS expansion enclosures in accordance with ISO 9296
(1,2,3)
.
Important: Hearing conservation program (HCP) procedures are required for field service personnel
servicing a 2077-92F, 2077-A9F or 2078-92F, 2078-A9F SAS expansion enclosure.

Notes:
1. Declared level L
WAd
is the upper-limit A-weighted sound power level. Declared level L
pAm
is the mean
A-weighted sound pressure level measured at the 1-meter bystander positions.
2. All measurements are made in conformance with ISO 7779 and declared in conformance with ISO
9296.
3. "B" and "dB" are abbreviations for bels and decibels, respectively. 1 B = 10 dB.
Important: Government regulations (such as those prescribed by OSHA or European Community
Directives) may govern noise level exposure in the workplace and may apply to you and your server
installation. This system is available with an optional acoustical door feature that can help reduce the
noise emitted from this system. The actual sound pressure levels in your installation depend upon a
variety of factors, including the number of racks in the installation; the size, materials, and configuration
of the room where you designate the racks to be installed; the noise levels from other equipment; the
room ambient temperature, and employees' location in relation to the equipment. Further, compliance
with such government regulations also depends upon a variety of additional factors, including the
duration of employees' exposure and whether employees wear hearing protection. IBM recommends
that you consult with qualified experts in this field to determine whether you are in compliance with the
applicable regulations.
