Table 1. Features and operating specifications (continued)
Notes:
1. Power consumption and heat output vary depending on the number and type of optional features that are
installed and the optional power-management features that are in use.
2. These levels are 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.
Models and optional devices
The storage subsystem components and configurations are explained in this topic.
