Features and specifications
The following information is a summary of the features and specifications of the
server. Depending on the server model, some features might not be available, or
some specifications might not apply.
Racks are marked in vertical increments of 1.75 inches. Each increment is referred
to as a unit, or “U.” A 1-U-high device is 1.75 inches tall.

Notes:
1. Power consumption and heat output
vary depending on the number and type
of optional features installed and the
power-management optional features 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
values stated 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.
