NOTE This section applies only to HP rp7410 and rp8400 servers.
The “doorbell” buttons currently have no functions. Pressing a card slot
doorbell button has no impact on system operations.
On both HP rp7410 and rp8400 servers, access to the doorbell buttons is
prevented by a plastic covering.
The PCI card slot doorbell buttons are provided for future expanded
functionality.
