F.A.Q.
p. 255
Fans - Fans can be replaced while the unit is in operation. If you need to replace a fan it is important
you are aware of the following:
• Don’t keep the unit running for long with the lid is off. Failing to do so will allow the unit to
overheat. The lid helps move the air in the proper direction for optimal cooling.
• Even broken fans can move. Be aware of moving fan blades and keep fingers and tools out of
the blade area.
• Watch for the moving fans you are not replacing. As above, your fingers and tools should stay
out of the area of any fan in the unit.
Drives - Drives can be replaced easily. Be careful to replace drives one at time if you wish to keep the
RAID set intact. When you remove a drive from a RAID set it take a period of time to “re-sync” the
RAID. Replacing more than one drive at a time could cause a loss of data. The G-RACK 12 chassis
supports twelve hot-swappable 3.5” hard drives, which may be removed without powering-down
the system. The drives are mounted in drive carriers to simplify their installation and removal from
the chassis. These carriers also help promote proper airflow for the drive bays.
Cables - All external cables can be replaced with cables sharing the same connectors and electrical
characteristics.
Dust - All environments have dust. Some more than others. It is recommended that you dust out the
unit with a vacuum and paint brush if you see dust gathered
around vents on the server.
