Chapter 2 Preparing for Installation
2.1 Safety Recommendations
To avoid possible bodily injury and equipment damage, please read the following safety
recommendations carefully before installing the S9500 series. The recommendations
do not cover every possible hazardous condition.
2.1.1 General Safety Recommendations
z
Take necessary safety measures to avoid injury and device damage. For example,
wear an ESD-preventive wrist strap.
z
Make sure that the ground is dry and flat and you have adopted anti-slip
measures.
z
Keep the chassis clean and dust-free. Do not place the switch on a moist area and
avoid liquid flowing into the switch.
z
Keep the chassis and installation tools away from walk areas.
2.1.2 Electrical Safety
z
Look carefully for possible hazards in your work area, such as ungrounded power
extension cables, missing safety grounds, and moist floors.
z
Locate the emergency power-off switch in the room before installation. Shut the
power off at once in case accident occurs.
z
Unplug all the external cables (including power cords) before moving the chassis.
z
Better not maintain the equipment alone when it has been powered.
z
Never assume but check each time that power has been disconnected from a
circuit.
2.1.3 ESD Damage Prevention
To prevent the electronic components from being damaged by the electrostatic
discharge (ESD), you should not only take ESD measures where the switch is located,
but also take the following precautions:
z
Always wear an ESD-preventive wrist strap when installing components,
especially the electronic printed circuit boards.
z
Hold the edges of the PCB when necessary. Do not touch any electronic
components or printed circuit.
Take the following steps to use the ESD-preventive wrist strap.
1)
Wear the wrist strap on your wrist.
2)
Lock the wrist strap tight around your wrist to keep good contact with the skin.
