Removing a fan module
!
Do not touch conductors or terminals on the fan modules.
Do not place the fan module in a moist place. Prevent liquid from entering the fan module.
Fan modules with faulty internal wiring and conductors require maintenance from maintenance
engineers. Do not disassemble the faulty fan modules.
To remove a fan module:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Grasp the two handles of the fan module, as shown by callout 1 in Figure 11, and pull out the
fan module slowly along the guide rails.
3. Put the removed fan module in an antistatic bag.
