Incorrect Values for Idle Input Power Requirements in
Minimum Server Configurations
The Power Source Requirements section of the SPARC Enterprise T5140 and T5240 Site
Planning Guide contains tables that identify power specifications for various server
configurations. These specifications include values for idle power use in minimum server
configurations. That is, server configurations that have the smallest amount of memory
possible as well as no hard drives and no PCIe I/O cards installed.
The idle power values in the published version of the Site Planning Guide are incorrect
because they were calculated based on servers with one hard drive installed instead of no
hard drives. Consequently, the idle power value for each configuration is too high by 8 Watts.
The following table provides the correct values (as well as the current incorrect values) for
each SPARC Enterprise T5140 and T5240 server configuration.
Configurations Described by Tables
T5140, 1.2 GHz CPU, 4-disk backplane
T5140, 1.2 GHz CPU, 8-disk backplane
