Attention: Your server installation may be subject to government regulations,
such as those prescribed by OSHA or European Community Directives, that cover
noise-level exposure in the workplace. The BladeCenter unit is available with an
optional acoustic attenuation module that can reduce the likelihood of exceeding
noise-level exposure limits. The actual sound-pressure levels in your installation
depends on a variety of factors, including the number of servers in the installation,
the size, materials, and configuration of the room where the servers are installed,
the noise levels from other equipment, the room ambient temperature, and
employees’ location in relation to the equipment. It is recommended that a qualified
person, such as an industrial hygienist, be consulted to determine whether the
sound-pressure levels to which employees may be exposed exceed regulatory
limits.
Rack considerations
IBM NetBAY
When planning for IBM NetBAY racks the following factors must be considered:
v
floor space that provides adequate access to the front and rear of the rack, and
space on both sides of the rack or a row of racks for ventilation and walk through
space. See Figure 9 on page 42.
v rack weight load limits and floor weight load limits. See Table 4 on page 44.
v
rack height – each BladeCenter unit requires 7U, also consider the space
needed for other equipment that might be installed in the same rack with the
BladeCenter units. See Table 4 on page 44.
Table 4 on page 44 shows the maximum weight limits for IBM NetBAY racks and
expansion cabinets that are recommended for use with BladeCenter units. The
table shows the maximum number of BladeCenter units that can be installed in a
NetBAY rack when the rack is either:
v
installed in placed and sitting on the rack leveling pads
v being relocated and is sitting on the rack casters.
v
is being shipped on a pallet.
