• Secure airflow clearance inside and around the rack cabinet.
• Secure an 18 to 20 cm clearance on the rear side.
• Do not cover the enclosure openings.
• Route the cables inside the rack cabinet.
• Do not leave drive bays empty as it will affect airflow efficiency.
• Secure each enclosure module using its retention screws.
• Placepowercordsandothercablesawayfromfoottraffic.Donotplaceitemsontopofpower
cords and ensure they do not rest against data cables.
• Install all modules to the enclosure before turning on the systems.
• Ensure that the correct power range is tested before turning on.
• DO NOT remove the covers or replaceable modules if they are not faulty.
• Ifthesystemisnotusedforalongperiodoftime,disconnectitfromthepoweroutlettoavoid

• Whenreplacingcomponents,insertthemasgentlyaspossiblewhileassuringfullengagement.
Vibration and shock can easily damage hard drives.
• Only qualified service personnel should open the enclosure.
• Contact service personnel if any of the following situations occurs:
• The power cord or plug is damaged.
• The enclosure has been exposed to moisture.
• The system has not been working properly.
• The enclosure was dropped against a hard surface.
• The enclosure shows obvious signs of breakage.
• Tomovetheenclosure,morethanonepersonmightbenecessaryduetoitsweight.Drivesshould
