Chapter 17 Troubleshooting
Cause
Check that the LAN cable is connected.
Switch off the switching hub power, then
restart the hub.
The problem may not be fixed by only
disconnecting and reconnecting the LAN
cable.
Set the board settings for the switching
hub that connects this product to
100Base/TX, FDX or 1000Base/T.
Remove the installation location base,
and if a connection cannot be established
between a hand-held HUB and the PC,
replace the main board.
•
Check that power supply of the server
PC is ON.
•
Check the connection of the LAN
cable.
•
Restart the DRYPRO 832 and the
server PC.
Cause
Press and hold the operation switch once
again for more than 10 seconds.
If the DRYPRO does shut down, check
the connection of the main
communication Assy, and if there are no
problems, replace the main board, MEC
board, and main communication Assy.
If the DRYPRO does not shut down, there
is a communication error between the
MEC board and multiple power supply.
Switch the main power supply OFF, and
follow the "Communication error
between MEC board and multiple power
supply" solution below. (When a forced
shutdown can be performed)
Replace the MEC board, multiple power
supply, and remote signal Assy.
