CAUTION
NOTE
Safely Powering Down the J5000 Workstation
You must complete the following steps before performing any of the
removal and replacement procedures:
Do not use the power supply interlock thumbscrew on the rear panel to
power down the workstation. This power down method may hang the
operating system in an unrecoverable state.
Remove any accessory bag(s) and their black tab screws, if present, from
the rear of the workstation.
1. Power off the workstation by simply pressing the power switch on the
front panel of the workstation. Also, power off the monitor and any
attached peripheral devices.
If necessary, shut down the workstation by executing "shutdown -h"
as user root). This ensures that all programs are terminated and all
data is saved before switching the power off.
2. After 30 seconds, unplug the workstation's power cord and all
peripheral devices from AC power outlets. Before attempting to move
the workstation to a disassembly area, disconnect all peripherals
from the back of the system.
3. Place the workstation on a flat, stable surface, such as a tabletop or
floor. To protect against scratches, remove miscellaneous debris from
the work surface.
