Refer to the illustration in “Guide for Raised-Floor Preparation” on page 104 for service clearances shown
in a raised-floor installation.
Cooling Requirements
The
Eserver
pSeries 655 requires air for cooling. As shown in
″
Proposed Floor Layout for Multiple
Systems
″
on page 116, rows of
Eserver
pSeries 655 systems must face front-to-front. The use of a
raised floor is recommended to provide air through perforated floor panels placed in rows between the
fronts of systems (the cold aisles shown in the figure on page 116).
The following table provides system cooling requirements based on system configuration. The letter
designations in the table correspond to the letter designations in the graph shown in “Cooling
Requirements Graph” on page 119.
