7. Be sure the keyboard or mouse is connected to the correct port. Determine
whether the keyboard lights flash at POST or the NumLock LED illuminates.
If not, change port connections.
8. Be sure the keyboard or mouse is clean.
Diagnostic adapter problems
Action: If the diagnostic adapter does not have hot-plug functionality, be sure
you are not using a PS/2 keyboard or mouse. With a PS/2 keyboard or mouse, the
diagnostic adapter cannot be connected as a hot-plug device. Connect the
diagnostic adapter before booting the server, or switch to USB devices (if
supported) to use the diagnostic adapter hot-plug functionality.
Modem problems
No dial tone exists
Action:
1. Be sure the cables are plugged in as specified in the modem documentation.
2. Connect a working telephone directly to the wall jack, and then test the line
for dial tone.
If the problem still occurs with the new mouse or keyboard, the
connector port on the system I/O board is defective. Replace the board.
If the problem no longer occurs, the original input device is defective.
Replace the device.
NOTE: The diagnostic adapter is used only with ProLiant BL servers.
