9 - AFTER THE TERMINAL HAS BEEN SWITCHED ON, THE MESSAGES
'NO ETHERNET BOARD PRESENT' AND 'CANNOT ATTACH
ETHERNET BOARD' APPEAR
This message indicates a hardware failure. Report the problem to your service
representative.
9 - A DOUBLE-BEEP SOUNDS
After switching on the terminal, a double beep may sound, a few seconds after
the normal first beep.
This signal indicates that keyboard initialization has failed. Check the keyboard
connection to the terminal back panel.
It is possible for the keyboard to function correctly, despite this double-beep
signal. As a quick test of keyboard operation, enter set-up mode by pressing the
<Ctrl><Alt><Esc> keys simultaneously. If set-up mode is working, you can
ignore the double beep signal and use the terminal normally.
9 - ETHERNET CONNECTION INDICATOR DOES NOT LIGHT
This indicator is the green LED located next to the network connector on the
terminal back panel.
Failure to light when the terminal is switched on may be due to any of the
following:
- the Ethernet cable is disconnected at the far end,
- the device (host or hub), to which the network cable is connected, is not
switched on,
- there is a fault on the Ethernet cable or the cable is wired with incorrect
pin assignments.
