WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system 
components to cool before touching them. 
CAUTION: Before removing the access panel, make sure that the server is powered down, all 
cables are disconnected from the back of the server, and the power cord is disconnected from 
the grounded (earthed) AC outlet.

integral part of the cooling system and removing it while the system is running may cause 
overheating and subsequent server shutdown.
