1. 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 specific 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.
7042-CR8 Hardware Management Console specifications
Hardware specifications for model 7042-CR8 provide detailed information for your Hardware
Management Console (HMC), including dimensions, electrical, power, temperature, environmental
specifications, and noise emissions.
The HMC controls managed systems, including the management of logical partitions and the use of
capacity on demand. Using service applications, the HMC communicates with managed systems to
detect, consolidate, and send information to IBM for analysis. The HMC provides service technicians with
diagnostic information for systems that can operate in a multiple-partitioned environment.
Use the following specifications to plan for your HMC.
