To access internal components, remove the top cover and follow these steps:
1. Turn off and disconnect the system power. Disconnect power at the DC source end of the
power cables, using the disconnect device that is part of the rack or facility power system.
2. Remove or loosen (as appropriate) the screws that fasten the server to the rack.
3. If the server is slide-mounted, slowly pull the chassis forward (or push from the rear) to
