Attention: For proper cooling and airflow, replace the side cover before you turn on the HMC. Operating the HMC for extended periods of time (more than 30 minutes) with the side cover removed might damage HMC components.

To replace the cover:

1. Make sure that all cables, adapters, and other components are installed and seated correctly and that you have not left loose tools or parts inside the HMC. Also, make sure that all internal cables are correctly routed.
2. If you removed the upper and lower bezels, reinstall them before you replace the side cover. (Refer to Removing and Replacing the Lower Bezel and Removing and Replacing the Upper Bezel.)
   
   Important: The cover lock must be in the unlocked (opened) position before you install the side cover.
   
   
3. Position the lip on the bottom edge of the side cover on the ledge on the bottom of the chassis. Then, tilt the top of the cover into position on the chassis until it latches securely into place.
4. Lock the side cover.
5. Reconnect the external cables and power cords. Then, turn on the attached devices and turn on the HMC.
