The Dell PowerEdge T550/T560 Security Bezel (21NXV) is designed to provide physical security for the T550 and T560 tower servers. It attaches to the front of the server, helping to prevent unauthorized access to the drives and enhancing the overall security of the system.
Constructed to match the tower form factor of the T550 and T560, this bezel includes a lock and key mechanism, ensuring that only authorized personnel can access the drives. Its design seamlessly integrates with the server, maintaining a professional appearance while adding an extra layer of protection.
