General Precautions
The procedures in this manual are for qualified service personnel.
Before beginning the installation, see the precautions in “Power Precautions.”
Be careful not to accidently insert your fingers into the fan tray while removing it from the chassis. The fan may still be spinning at a high speed.
Changes or modifications made to this device that are not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
Disassembling any part of the power supply and fan assembly voids the warranty and regulatory certifications. There are no user-serviceable parts inside the power supply and fan assembly.
Make sure the airflow around the front and back of the device is not restricted.
Ensure that the airflow direction of the power supply unit matches that of the installed fan tray. The power supplies and fan trays are clearly labeled with either a green arrow with an "E" or an orange arrow with an "I."
Never leave tools inside the chassis.
To protect the serial port from damage, keep the cover on the port when not in use.
If you do not install a module or a power supply in a slot, you must keep the slot filler panel in place. If you run the chassis with an uncovered slot, the system will overheat.
Do not install the device in an environment where the operating ambient temperature might exceed 40°C (104°F).
