Replacing the side cover
Use this information to replace the side cover.
Attention: For proper cooling and airflow, replace the side cover before turning
on the server. Operating the server for extended periods of time (more than 30
minutes) with the side cover removed might damage server components.

steps to remove the side cover. For the 5U server model with hot-swap power
supplies, please see the next sub-section.
1. Read the safety information in “Safety” on page vii and “Installation

locks securely into place.
5. Secure the side cover in place with the two chassis screws on the rear of the
side cover.
6. Reconnect the external cables and power cords; then, turn on the attached
devices and turn on the server.
