Installing the operating temperature enhancement kit

Use this information to install the operating temperature enhancement kit.

Attention

To ensure proper cooling and airflow, do not operate the server for more than 30 minutes with the side cover removed.

To install the operating temperature enhancement kit on 4U server models with non-hot-swap power supplies, complete the following steps. For the 5U server model with hot-swap power supplies, please see the next sub-section.

1. Read the safety information in Safety and Installation guidelines.
2. Turn off the server and all attached devices; then, disconnect all power cords and external cables.
3. Remove the bezel (see Removing the bezel).
4. Carefully turn the server on its side so that it is lying flat, with the cover facing up.
   Attention

   Do not allow the server to fall over.
5. Remove the side cover (see Removing the side cover).
6. Insert the thermal sensor board into the thermal sensor holder. Attach the holder onto the server and make sure that the cabling goes through the hole as shown in the illustration.
