6. CHECKUP AND MAINTENANCE
6-6
6.3.2 Before installing or removing components
When you install or removing components, confirm and adhere strictly to the following
instructions.
WARNING
● Do not open the equipment cover if you are not maintenance personnel.
In addition, do not install or replace the hardware.
● Before you start the work, make sure you shut down the OS, unplug the
power cord from the outlet, and wait for at least one minute. Otherwise,
an electric shock or failure of the equipment may result.
CAUTION
Do not directly touch the parts inside the equipment with your hand when you
install or remove an extension board. Those parts are hot and if you touch them,
you may get burned. In addition, if you touch them, they may get damaged and
that may result in failure of the equipment.
・
Allocate sufficient clearance for maintenance work. Carry out the work on a flat surface.
(See “1.6.2 Installation”.)
・
Wear cotton gloves when you install or remove components.
・
When you tighten or remove a screw, use a Phillips screwdriver (JIS #1 or JIS#2) to avoid
stripping the head.
・
When you tighten a screw, drive the screw along the axis of the tapped hole without adding
too much torque in order to avoid damaging the thread.
As well as the above, there are instructions for every work item. Confirm and adhere strictly
to these instructions.
