Unplug the power cord first.
There is more than one connector. As you flip the front down, mark each one and/or take a photo so you know the correct orientation.
The connectors have a lock, you can practice with the easily accessible ones running from the power supply (but don't remove any there, remove from the front panel). This lock can break if you aren't careful.
Straighten any slightly bent leads when you go to reinsert and make sure each one is in the correct hole before locking the connector.
THANKS!!
