Installing and Replacing Other Components
Note
Because power to an appliance is automatically disconnected
when the chassis tray assembly is opened, you do not need to manually
disconnect the power for this procedure. Any servicing of the unit,
however, should be completed with the chassis tray assembly fully
removed from the appliance. Power is still active in the chassis body and
care should be taken when working on the power supply or power supply
wiring without disconnecting the power cord.
Caution
You risk damage to the appliance or loss of data if you do not use the
following procedure when you replace the compact flash memory.
1. Use Network Voyager or the CLI to halt the appliance.
To use Network Voyager to shut the appliance down, select
System > Configuration > Reboot or Shutdown > Halt.
To use the CLI to shut the appliance down, enter halt at the prompt.
2. Turn off the power to the IP390 appliance.
Note
Make sure you turn off the power supply.
3. Loosen the two front panel retaining screws.
