Chapter 2 Installing the Sun Fire X4150 Server Into a Rack with Slide-Rails 11
Caution – Always load equipment into a rack from the bottom up so that it will not
become top-heavy and tip over. Deploy your rack’s anti-tip bar to prevent the rack
from tipping during equipment installation.
Caution – Ensure that the temperature in the rack does not exceed the server’s
maximum ambient rated temperatures. Consider the total airflow requirements of all
equipment installed in the rack to ensure that the equipment is operated within its
specified temperature range.
