Removing a fan module
WARNING!
• Ensure electricity safety and never touch the rotating fans when you hot-swap a fan module.
• To prevent a fan from causing loud noise, do not touch the fan blades and rotation axis, even if
the fan is not rotating.
To remove a fan module:
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Press the red part of the handle with one hand and pull the fan module part way out of the slot.
Supporting the fan module bottom with the other, pull the fan module completely out of the slot
along the guide rails.
3.
Put the removed fan module in an antistatic bag.
