Reinstalling the chassis covers:
To maintain proper system cooling and airflow, do not operate the system
without installing all chassis covers back to the chassis. To reinstall the
chassis covers, please follow the steps listed below:
1. Make sure that all components and devices are securely fastened on
the chassis and there are no loose parts/screws inside the chassis.
2. Make sure that all cables are properly connected to the connectors
and ports.
3. Use the original screws or fasteners to install the covers to the chas-
sis.
4. Be sure to lock the chassis or the system to prevent unauthorized
access.
5. For proper cooling, enclose the chassis with covers before operat-
ing the system.
Before installing the chassis into a rack:
1. Make sure that the rack is securely anchored onto an unmovable
surface or structure before installing the chassis into the rack.
2. Unplug the power cord(s) of the rack before installing the chassis
into the rack.
3. Make sure that the system is adequately supported. Make sure that
all the components are securely fastened to the chassis to prevent
components falling off from the chassis.
4. Be sure to install an AC Power Disconnect for the entire rack
assembly and this Power Disconnect must be clearly marked.
5. The rack assembly shall be properly grounded to avoid electric
shock.
6. The rack assembly must provide sufficient airflow to the chassis for
proper cooling.
