All PowerEdge servers have key locks on their front bezels to prevent access to the systems resources.
There is a single key lock implementation with a single key code across all PowerEdge tower and rack
servers.
Key orientation is as follows: Vertical (12 o'clock) position is unlocked. Right (3 o'clock) position is locked.
For rack systems, the bezel locks all front panel access.
