Safely Powering Down the J6700 Workstation
You must complete the following steps before performing any of the removal and
replacement procedures:
CAUTION 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.
NOTE Remove any accessory bag(s) and their black tab screws, if present, from the
rear of the workstation. Remove any existing SCSI terminators.
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.
