4-4 SPARC Enterprise Mx000 Servers XSCF User’s Guide • August 2009
The M8000/M9000 servers do not indicate Middle speed. The M3000 server
indicates multi levels. In case errors detected in the fan, Full or High speed will be
indicated.
TABLE 4-1, TABLE 4-2 and TABLE 4-3 list the fan speed level indicated by using the
showenvironment(8) command, which corresponding to the altitude configured
and the environmental temperature.
For the altitude setting, see Section 2.2.15, “Altitude Administration” on page 2-137
