Remove a Fan Module

The 4 fan modules are user-serviceable, hot-pluggable components. Each module has 2 fans. In normal circumstances, you should shutdown the system near the fan's end of life and replace it with a new fan. However, if a fan malfunctions while the system is running, remove the fan and quickly replace it with a functional fan to prevent overheating.

WARNING:

Overheating can stop packet processing.

If you do not have a replacement fan on hand, shut down the system and disconnect the power before removing the malfunctioning fan.

Note:

When removing and replacing a fan, remember to first ground yourself using appropriate ESD grounding equipment such as a wrist or heel strap.
  1. Remove the top cover.
  2. Grasp the fan module by its center handle and pull it out.
