Utilities
Consider the proximity to required utilities, such as power, water, and network connections. While the
required utilities can be brought to nearly any selected site, there is the potential for increased costs and
decreased efficiency when the HP POD 20c is located farther from the utility sources.
For utility clearance information, see "Dimensions and clearances (on page 8)."
