Important Safety Information 7

Fans
WARNING
To avoid injury do not contact moving fan blades.
Electrostatic Discharge (ESD)
CAUTION
Perform the procedures in this chapter only at an electrostatic discharge
(ESD) workstation, because the server components can be extremely
sensitive to ESD. If no such station is available, you can reduce the risk of
electrostatic discharge ESD damage by doing the following:
• Wear an antistatic wrist strap and attach it to a metal part of the server.
• Touch the metal on the server chassis before touching the server components.
• Keep part of your body in contact with the metal server chassis to dissipate
the static charge while handling the components.
• Avoid moving around unnecessarily.
• Hold the server components (especially boards) only by the edges.
• Place the server components on a grounded, static-free surface. Use a
conductive foam pad if available but not the component wrapper.
• Do not slide the components over any surface.
Cooling and Airflow
CAUTION
For proper cooling and airflow, always install all access covers before
turning on the system. Operating the system for longer than five minutes
without the covers in place can cause overheating and damage to system
components.
Lifting and Moving
CAUTION
Do not attempt to lift or move the server by the handles on the power
supplies.
Equipment Rack Precautions
Follow the rack manufacturer’s safety and installation instructions for proper rack installation. The
following additional rack safety installation measures shall be considered:

ANCHOR THE EQUIPMENT RACK
The equipment rack must be anchored to an unmovable suitable support to
prevent the rack from falling over when one or more systems are fully
extended out of the rack assembly. You must also consider the weight of any
other devices installed in the rack assembly. The equipment rack must be
installed according to the manufacturer's instructions.
MAIN AC POWER DISCONNECT
You are responsible for installing an AC 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 system(s).
GROUNDING THE RACK INSTALLATION
To avoid the potential for an electrical shock hazard, the rack assembly itself
must be suitably earth grounded, according to your local regional electrical
codes. This typically will require the rack to have its own separate earth
ground. We recommend you consult your local approved electrician.
OVER CURRENT PROTECTION
The system is designed to operate on a 20A AC voltage source that is
provided with 20A over current protection. If the AC source for the rack
exceeds 20A over current protection, each system must be provided with
20A or less over current supplemental protection. The supplementary over
current protection must have the appropriate regional safety certifications for
the over current application.
TEMPERATURE LIMITS
The operating temperature of the system, when installed in the rack, must not
go below 10 °C (50 °F) or rise above 35 °C (95 °F). Extreme fluctuations in
temperature may cause a variety of problems in system, and safety limits
may be broken.
VENTILATION CONSIDERATIONS
The equipment rack must provide sufficient airflow to the front of the system
to maintain proper cooling. The rack selected and the ventilation provided
must be suitable to the environment in which the system will be used.
Important Safety Information 9

Important Set-Up Safety Information
WARNINGS
The power supply in this product contains no user-serviceable parts. There may be more than
one supply in this product. Refer servicing only to qualified personnel.
Do not attempt to modify or use the supplied AC power cord if it is not the exact type required.
A product with more than one power supply will have a separate AC power cord for each
supply.
The power button on the system does not turn off system AC power. To remove AC power
from the system, you must unplug each AC power cord from the wall outlet or power supply.
The power cord(s) is considered the disconnect device to the mains (AC) power. The socket
outlet that the system plugs into shall be installed near the equipment and shall be easily
accessible.
SAFETY STEPS: Whenever you remove the chassis covers to access the inside of the
system, follow these steps:
1. Turn off all peripheral devices connected to the system.
2. Turn off the system by pressing the power button.
3. Unplug all AC power cords from the system or from wall outlets.
4. Label and disconnect all cables connected to I/O connectors or ports on the back of the
system.
5. Provide some electrostatic discharge (ESD) protection by wearing an antistatic wrist strap
attached to chassis ground of the system—any unpainted metal surface—when handling
components.
6. Do not operate the system with the chassis covers removed.
After you have completed the six SAFETY steps above, you can remove the system covers.
To do this:
1. Unlock and remove the padlock from the back of the system if a padlock has been installed.
2. Remove and save all screws from the covers.
3. Remove the covers.
For proper cooling and airflow, always reinstall the chassis covers before turning on the
system. Operating the system without the covers in place can damage system parts. To
install the covers:
1. Check first to make sure you have not left loose tools or parts inside the system.
2. Check that cables, add-in boards, and other components are properly installed.
3. Attach the covers to the chassis with the screws removed earlier, and tighten them firmly.
4. Insert and lock the padlock to the system to prevent unauthorized access inside the system.
5. Connect all external cables and the AC power cord(s) to the system.
