6 Shutting Down and Restarting
Restart
Procedures
The restart procedures are used to effect network setup changes,
and are part of other procedures recommended in this manual.
The methods available to you, listed below, depend on the state of
the server.
•
From the normal operating state, you can shutdown and
immediately restart the server using HD Server Admin’s
Configuration Æ Shutdown/Restart
page. Click
Shutdown and
Restart
and
[Apply]
.
•
From the shutdown state, you can restart the server at the
control panel by pressing
✔
when it displays
Power off or ✔
to restart
.
•
From fault conditions that halt or freeze the server, it will
automatically restart if the
Automatic Restart
parameter is
enabled. If the parameter is disabled (as it is by default) or
auto-restart has occurred three times, then the server halts and
displays a message on the control panel instructing you to
Power off or ✔ to restart
.
•
From fault conditions causing HD Server Admin to be
unavailable, perform the shutdown or power cycle procedure
from the control panel (see those procedures in this section).
After restarting, the server performs the initialization process,
described starting at step 3 in “Startup Steps” on page 6-1.
Power Cycle
Procedure
Use the power cycle procedure only when necessary to replace failed
components or to move the server to another physical location or
network location (that is, to connect a network cable). Hard disk
drive modules can be replaced using just the shutdown procedure.
CAUTION!
❏
Switching the server’s power off without following the
appropriate shutdown procedure can result in lost user data.
Always make sure it is safe to cycle the power before doing so.
Alert users that the server will be off line (unavailable) while
shut down; then begin the shutdown procedure before switching
off power, as described here.
1. Perform a shutdown procedure using one of the methods
described in “Shutdown Procedures” on page 6-5.
2. When prompted
Power off or ✔ to restart
on the control panel
display, press the power switch to switch power off.
3. When ready to restart the server (at least 10 seconds later, so that
the disk drives stop spinning), switch on the power switch and
follow the initialization process starting at step 3 on page 6-1.
