Installing a hot-swap fan - Lenovo System x3550 M4

Use this information to install a hot-swap fan.

The server comes standard with four dual-motor hot-swap cooling fans. When there is one microprocessor installed, install fan 1, 2, 3, and 5 for proper cooling.

Attention: To ensure proper operation, replace a failed hot-swap fan within 30 seconds.

To install an additional hot-swap fan, complete the following steps:

Read the safety information that begins on Safety and Installation guidelines.
Remove the cover (see Removing the cover).
Remove the fan filler panel (if it has not been removed already). Keep the filler panel in a safe place.
Touch the static-protective package that contains the new fan to any unpainted metal surface on the server. Then, remove the new fan from the package.
Figure 1. Fan installation
Orient the fan over the fan slot in the fan assembly bracket so that the fan connector aligns with the connector on the system board.
Figure 2. Fan installation
Insert the fan into the fan slot in the fan assembly bracket and press it down until it is seated correctly in the slot and the fan connector is seated correctly in the connector on the system board.
Note: Make sure that the newly-installed fan aligns horizontally with other correctly-seated fans for proper installation.

If you have other devices to install or remove, do so now. Otherwise, go to Completing the installation.
