 Do not access the inside of the power supply. There are no serviceable parts
in the power supply. Return to manufacturer for servicing.
 Power down the server and disconnect all power cords before adding or
replacing any non hot-plug component.
 When replacing a hot-plug power supply, unplug the power cord to the
power supply being replaced before removing the power supply from the
server.
If the server has been running, any installed processor(s) and heatsink(s) may
be hot. Unless you are adding or removing a hot-plug component, allow the
system to cool before opening the covers.
To avoid the possibility of coming into contact with hot component(s) during
a hot-plug installation, be careful when removing or installing the hot-plug
component(s).
Rack mount guidelines
 The equipment rack must be anchored to an unmovable support to prevent it
from tipping when equipment is extended from it.
 You must consider the weight of any other device installed in the rack. A crush
hazard (serious injury) exists if the rack tilts forward.
 The equipment rack must be installed according to the rack manufacturer's
instructions.
 Install equipment in the rack from the bottom up, with the heaviest equipment
at the bottom of the rack.
 Extend only one piece of equipment from the rack at a time.
 You are responsible for installing a main power disconnect for the entire rack
unit. This main disconnect must be readily accessible, and it must be labeled as
controlling power to the entire unit, not just to the server(s).
 To avoid risk of potential electric shock, a proper safety ground must be
implemented for the rack and each piece of equipment installed in it.
 The temperature in the room where the devices operate must not be below 5 °C
(41 °F) or above 40 °C (104 °F). Extreme fluctuations in temperature can cause
problems in your equipment.
