POWERING DOWN THE D400
CHAPTER 5: POWERING UP THE D400
Powering down the D400
Powering down or shutting down the D400 without using the proper procedure could
result in loss of system log data (SOE log, alarm log, user log, etc.), and could prevent the
D400 from restarting properly. Follow the instructions provided to shut down the D400
safely.
The D400 is like a computer and the system must be shut down properly before removing
the power. For the shut down procedure, see “Shutting down the D400” on page 98.
NOTE
It may take a couple of minutes for the D400 to fully shut down and for the CPU Ready LED
to go off.
Once you have completely shut down the D400, you can safely disconnect the power.
