Remove a fan

Use this information to remove a fan from the compute enclosure.

To avoid possible danger, read and follow the following safety statement.

S017
moving parts
CAUTION:
Hazardous moving fan blades nearby.
S033
240VA shock hazard
CAUTION:

Hazardous energy present. Voltages with hazardous energy might cause heating when shorted with metal, which might result in spattered metal, burns, or both.

Before removing a fan:

  1. Remove the fan cover (see http://thinksystem.lenovofiles.com/help/topic/7X21/remove_the_fan_cover.html).

    Attention:
    • Static electricity released into internal solution components when the solution is powered on may cause the solution to halt, which may result in data loss. To avoid this problem, always use an electrostatic-discharge wrist strap or other grounding system when you work inside the solution with the power on.

    • Replace the failed fan and reinstall the fan cover in three minutes.

  2. Identify the failed fan. The following illustration shows locations of fan fault LEDs. When the LED is lit, it indicates the fan is having operational issues.
