Notes:
1. Power consumption and heat
output vary depending on the
number and type of optional
features that are installed and the
power-management optional
features that are in use.
2. These levels were measured in
controlled acoustical environments
according to the procedures
specified by the American National
Standards Institute (ANSI) S12.10
and ISO 7779 and are reported in
accordance with ISO 9296. Actual
sound-pressure levels in a given
location might exceed the average
stated values because of room
reflections and other nearby noise
sources. The declared sound-power
levels indicate an upper limit, below
which a large number of computers
will operate.
What the IBM System Storage EXP3000 offers
